Federal Register / Vol. 77, No. 141 / Monday, July 23, 2012 / Rules and Regulations
For the reasons discussed above, I
certify that this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Is not a ‘‘significant rule’’ under
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities
under the criteria of the Regulatory
Flexibility Act.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation
safety, Incorporation by reference,
Safety.
Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:
PART 39—AIRWORTHINESS
DIRECTIVES

(d) Subject
Joint Aircraft System Component (JASC)/
Air Transport Association (ATA) of America
Code 53, Fuselage.
(e) Unsafe Condition
This AD was prompted by reports of
fatigue cracks in the lap joints, which
initiated at scribe lines that were made
during production when maskant was
removed from the affected skin panels during
the chemical milling process. We are issuing
this AD to detect and correct such fatigue
cracking, which could grow large and cause
sudden decompression and the inability to
sustain limit flight and pressure loads.

revising the Airworthiness Limitations
(AWLs) section of the Instructions for
Continued Airworthiness by

incorporating new limitations for fuel
tank systems to satisfy Special Federal
Aviation Regulation No. 88
requirements. That AD also requires the
initial inspection of certain repetitive
AWL inspections to phase-in those
inspections, and repair if necessary.
This new AD requires actions that were
provided previously as optional actions,
and would require a certain initial
inspection to be accomplished for a
revised AWL. This AD was prompted by
a report that an AWL required by the
existing AD must be revised. We are
issuing this AD to prevent the potential
for ignition sources inside fuel tanks
caused by latent failures, alterations,
repairs, or maintenance actions, which,
in combination with flammable fuel
vapors, could result in a fuel tank
explosion and consequent loss of the
airplane.
DATES: This AD is effective August 27,
2012.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of August 27, 2012.
The Director of the Federal Register
approved the incorporation by reference
of a certain other publication listed in
this AD as of June 12, 2008 (73 FR

SUPPLEMENTARY INFORMATION:
(n), and (o) of the NPRM, respectively)
to reference Boeing TR 09–011, dated
November 2010, to Section 9,
‘‘Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements
(CMRs),’’ of the Boeing 757 MPD
Document, D622N001–9.
Discussion
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to supersede airworthiness
directive (AD) AD 2008–10–11,
Amendment 39–15517 (73 FR 25974,
May 8, 2008). That AD applies to the
specified products. The NPRM
published in the Federal Register on
April 8, 2011 (76 FR 19710). That NPRM
proposed to continue to require revising
the Airworthiness Limitations (AWLs)
section of the Instructions for Continued
Airworthiness by incorporating new
limitations for fuel tank systems to
satisfy Special Federal Aviation
Regulation No. 88 requirements, and the
initial inspection of certain repetitive
AWL inspections to phase-in those
inspections, and repair if necessary.
That NPRM also proposed to require
actions that were provided previously as
optional actions, and would require a
certain initial inspection to be
accomplished for a revised AWL.
Request To Allow Use of Later
Revisions to Certain Service
Information
UAL requested that additional
revisions of service information be
included in paragraphs (s) and (t) of the
NPRM (76 FR 19710, April 8, 2011).
UAL noted in particular, the MPD
revisions approved by the ACO after
publication of AD 2008–10–11,
Amendment 39–15517 (73 FR 25974,
May 8, 2008). Since paragraphs (g), (h),
and (i) of AD 2008–10–11 allow the use
of a later revision of the MPD that is
approved by the Seattle ACO without
requesting an alternative method of
compliance (AMOC), UAL believed that
operators that used those later revisions
after publication of AD 2008–10–11,
without an AMOC, for the actions
required by paragraphs (g), (h), and (i)
of that AD would be in violation of the
NPRM because they would not receive
credit for using those revisions.
We agree that for paragraph (h) of this
AD (the restated actions of AD 2008–10–
11, Amendment 39–15517 (73 FR
25974, May 8, 2008)), the following
revisions of the MPD are acceptable.
Section 9, ‘‘Airworthiness Limitations
(AWLs) and Certification Maintenance
Requirements (CMRs),’’ of the Boeing
757 MPD Document, D622N001–9,
Revision December 2008; Boeing TR 09–
010, dated July 2010, to Section 9,
‘‘Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements
(CMRs),’’ of Boeing 757 MPD Document,
D622N001–9; and Boeing TR 09–011,
dated November 2010, to Section 9,
‘‘Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements
(CMRs),’’ of the Boeing 757 MPD
Document, D622N001–9; are the
acceptable revisions that have been
approved after June 12, 2008 (the
effective date of AD 2008–10–11). No
AMOC approval is needed to use any of
those three documents. We have revised
paragraph (h) of this AD accordingly,
and also paragraphs (k), (l), (m), and (n)
of this AD (paragraphs (l), (m), (n), and
(o) of the NPRM (76 FR 19710, April 8,
2011)) to reference all three MPD
revisions that are acceptable for
compliance with the requirements of
this AD.
No change is necessary for paragraph
(g) of this AD, because paragraph (k) of
this AD (paragraph (l) of the NPRM (76
FR 19710, April 8, 2011)) (which
Comments
We gave the public the opportunity to
participate in developing this AD. We
have considered the comments received.
Boeing supports the NPRM (76 FR
19710, April 8, 2011).
Request To Refer to the Most Recent
Revision of Service Information
United Airlines (UAL) requested that
paragraph (l) of the NPRM (76 FR 19710,
April 8, 2011) be revised to allow use
of Boeing Temporary Revision (TR) 09–
010, dated July 2010, to Section 9,
‘‘Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements
(CMRs),’’ of the Boeing 757
Maintenance Planning Data (MPD)
Document, D622N001–9; or Boeing TR
09–011, dated November 2010, to
Section 9, ‘‘Airworthiness Limitations
(AWLs) and Certification Maintenance
Requirements (CMRs),’’ of the Boeing
757 MPD Document, D622N001–9; to
comply with the proposed requirements
of that paragraph.
We infer that the commenter would
like the AD to reference the current
revision of the service information. We
agree to revise this AD to refer to the
most recent revision. We have revised
paragraph (k) of this AD (paragraph (l)
of the NPRM (76 FR 19710, April 8,
2011), and also paragraphs (h), (l), (m),
and (n) of this AD (paragraphs (h), (m),

terminates the requirements of
paragraph (g) of this AD) has been
revised to include those three MPD
revisions.
Also, no change is necessary to
paragraph (i) of this AD, because that
paragraph does not reference service
information. The paragraph clarifies that
after accomplishing paragraphs (g) and
(h) of this AD (except as required by
paragraphs (k) and (l) of this AD
respectively), no alternative inspections,
inspection intervals, or critical design
configuration control limitations
(CDCCLs) are acceptable unless
approved in accordance with the
procedures specified in paragraph (s) of
this AD.
Since we have included the MPD
revision that was proposed as credit by
paragraph (s) of the NPRM (76 FR
19710, April 8, 2011) as an MPD
revision that is acceptable for
compliance with this AD, we have
deleted paragraph (s) of the NPRM (and
re-identified paragraph (t) of the NPRM
as paragraph (r)(2) of this AD) from this
AD.
We do not agree that any revision to
paragraph (r)(2) of this AD (paragraph (t)
of the NPRM (76 FR 19710, April 8,
2011)) is necessary. Paragraph (r)(2) of
this AD gives credit for a certain
revision of the MPD for paragraphs (m)
and (n) of this AD (paragraphs (n) and
(o) of the NPRM), which are not a part
of the existing actions of AD 2008–10–
11, Amendment 39–15517 (73 FR
25974, May 8, 2008). We have not
revised this AD in this regard.
Request To Revise Wording in Certain
AWLs
UAL requested that wording in
certain AWLs that refer to ‘‘later
revisions’’ of component maintenance
manuals (CMMs) be removed. UAL
noted that the FAA removed references
to ‘‘a later revision’’ of Section 9 of the
Boeing 757 MPD Document, D622N001–
9 (referenced as Boeing TR 09–008,
dated March 2008, to Section 9,
‘‘Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements
(CMRs),’’ of the Boeing 757 MPD
Document, D622N001–9, in AD 2008–
10–11, Amendment 39–15517 (73 FR
25974, May 8, 2008)), to be consistent
with FAA policy and with Office of the
Federal Register regulations for
approving materials that are
incorporated by reference. UAL stated
that section 51.1(f) of the Code of
Federal Regulations (1 CFR 51.1(f))
prohibits the incorporation by reference
of future amendments or revisions of
publications, and because specific
revisions of the Boeing 757 MPD
Document, D622N001–9, are
VerDate Mar<15>2010
16:44 Jul 20, 2012
Jkt 226001
incorporated by reference into the
Federal Register, UAL believed that the
MPD should also omit language
referring to future revisions of CMMs.
We disagree with the request.
Paragraphs (g)(3) and (k)(3) (paragraph
(l)(3) of the NPRM (76 FR 19710, April
8, 2011)) of this AD do not require
operators to comply with applicable
AWLs, but instead, require operators to
incorporate applicable AWLs into their
maintenance program. Once those
applicable AWLs are incorporated into
the operators’ maintenance programs,
operators are in compliance with
paragraphs (g)(3) and (k)(3) of this AD.
Compliance with the condition defined
in each AWL is required by section
91.403(c) of the Federal Aviation
Regulations (14 CFR 91.403(c)) as stated
in Note 1 of the NPRM (76 FR 19710,
April 8, 2011). Because this AD does not
mandate compliance with the AWLs,
any documents specified in the AWLs
are not incorporated by reference in the
Federal Register, and therefore, section
51.1(f) of the Code of Federal
Regulations (1 CFR 51.1(f)) does not
apply. We have not changed this AD in
this regard.
Request To Clarify Differences Between
Paragraphs (l)(3), (i), and (p) of the
NPRM (76 FR 19710, April 8, 2011)
UAL requested further clarification in
regards to paragraphs (i), (l)(3), and (p)
of the NPRM (76 FR 19710, April 8,
2011). UAL noted that certain AWLs
contain reference to later revisions of
component maintenance manuals
(CMMs). However, paragraphs (i) and
(p) of the NPRM state that once certain
AWLs are incorporated into the
maintenance program, ‘‘no alternative
inspections, intervals, or CDCCLs may
be used unless * * * approved as an
AMOC * * *.’’ Given this restriction,
UAL believes that as long as certain
AWLs specify ‘‘later revisions’’ of
certain documents, it would not be
possible to comply with paragraphs (i)
and (p) of the NPRM. UAL also asked if
every future revision of a CMM
approved by the Seattle ACO would
require separate AMOC approval to
satisfy the requirements of paragraphs
(i) and (p) of the NPRM.
We agree to provide clarification.
There is no conflict between the
requirements of paragraph (k)(3) of this
AD (paragraph (l)(3) of the NPRM (76 FR
19710, April 8, 2011)) and paragraphs (i)
and (o) of this AD. Paragraphs (i) and (o)
(paragraphs (i) and (p) of the NPRM) of
this AD prohibit the use of an
alternative inspection, inspection
interval, or CDCCL unless it is approved
as an AMOC. The intent of paragraphs
(i) and (o) of this AD is to prohibit the
PO 00000
Frm 00018
Fmt 4700
Sfmt 4700
use of an alternative AWL without
AMOC approval, as each AWL defines
an inspection, inspection interval, or
CDCCL. If an operator desires to use an
alternative AWL, such as an AWL
defined in an MPD revision that is
different from those specified in
paragraphs (g)(3) and (k)(3) of this AD,
that operator must obtain AMOC
approval to use that alternative AWL, as
required by paragraphs (i) and (o) of this
AD. Once operators incorporate the
AWLs required by this AD or alternative
AWLs that have been approved as an
AMOC into their maintenance program,
they are in compliance with the
requirements of paragraphs (g)(3) and
(k)(3) of this AD, as applicable. After
incorporation of the AWLs, operators
are required to comply with each AWL
by 14 CFR 91.403(c). Operators are in
compliance with those AWLs as long as
they use CMM revisions that have been
approved by the Seattle ACO. Therefore,
separate AMOC approval is not
necessary to use CMM revisions that
have been approved by the Seattle ACO.
We have not changed this AD in this
regard.
Request To Consolidate Paragraphs (i)
and (p) of the NPRM (76 FR 19710,
April 8, 2011)
UAL requested that we consolidate
paragraphs (i) and (p) of the NPRM (76
FR 19710, April 8, 2011) into a single
paragraph. UAL stated that it found
what it considers to be an overlap
between paragraphs (i) and (p) of the
NPRM. UAL suggested that
consolidating the paragraphs would
streamline the AD and reduce confusion
for operators.
We disagree. Paragraph (i) of this AD
is a part of the restatement of the
existing requirements of AD 2008–10–
11, Amendment 39–15517 (73 FR
25974, May 8, 2008), and is for the
restated requirements of paragraphs (g)
and (h) of this AD. Paragraph (o) of this
AD (paragraph (p) of the NPRM (76 FR
19710, April 8, 2011)) is part of the new
requirements of this superseding AD,
and is intended to be effective once the
revision required by paragraph (k) of
this AD is done. We have not changed
this AD in this regard. However, we
have clarified paragraph (i) of this AD
by noting that doing the actions
required by paragraph (k) of this AD is
an exception to the requirements of
paragraph (i) of this AD.
Request To Consolidate the Credit
Paragraphs
UAL requested that we consolidate
paragraphs (j), (s), and (t) of the NPRM
(76 FR 19710, April 8, 2011) into a
single paragraph. UAL requested this

Federal Register / Vol. 77, No. 141 / Monday, July 23, 2012 / Rules and Regulations
mstockstill on DSK4VPTVN1PROD with RULES
action for the convenience of providing
operators a single paragraph to
reference. In an example that UAL
provided, UAL suggested combining
paragraphs (j) and (s) of the NPRM into
one sub-paragraph with the same
effective date of June 12, 2008, and
paragraph (t) of the NPRM as the other
sub-paragraph with an effective date of
‘‘before the effective date of this AD.’’
We partially agree. Paragraph (s) of
the NPRM (76 FR 19710, April 8, 2011)
has been deleted as previously
discussed. Paragraphs (j) and (t) of the
NPRM can be consolidated. We have
removed paragraph (j) of the NPRM, reidentified subsequent paragraphs, and
relocated the information from
paragraph (j) of the NPRM to paragraph
(r)(1) of this AD. The information in
paragraph (t) of the NPRM is now in
paragraph (r)(2) of this AD.
Request To Clarify or Revise the
Effective Dates in Regards to a Certain
Revision Level of the MPD Document
UAL requested that we revise a
sentence in paragraph (h) of the NPRM
(76 FR 19710, April 8, 2011) that reads
‘‘After the effective date of this AD, only
* * * may be used’’ to allow 6 months
before requiring operators to use the
current revision of the MPD when
complying with the initial inspection
requirements of paragraph (h) of the
NPRM. UAL noted that paragraph (h) of
the NPRM proposed to require use of
Boeing TR 09–010, dated July 2010, to
Section 9, ‘‘Airworthiness Limitations
(AWLs) and Certification Maintenance
Requirements (CMRs),’’ of Boeing 757
MPD Document, D622N001–9,
immediately after the effective date of
the AD, while paragraph (l) of the
NPRM would have allowed 6 months to
incorporate the Boeing TR 09–010,
dated July 2010, to Section 9,
‘‘Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements
(CMRs),’’ of Boeing 757 MPD Document,
D622N001–9, into the maintenance
program. UAL is concerned about the
effect that such a short compliance time
could have on airplanes on which the
operator started the initial inspection
(using a previous revision of the MPD)
before the effective date of the AD and
completes the inspection after the
effective date of the AD.
We agree to revise paragraph (h) of
this AD to allow 6 months after the
effective date of this AD before
operators are required to do initial
inspections using Section 9,
‘‘Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements
(CMRs),’’ of the Boeing 757 MPD

dated November 2010, to Section 9,
‘‘Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements
(CMRs),’’ of the Boeing 757 MPD
Document, D622N001–9. This change
would make paragraphs (h) and (k) of
this AD more consistent with each
other.
Request To Confirm Existence of
Paragraph (h)(2) of the NPRM (76 FR
19710, April 8, 2011)
UAL stated that it could not confirm
the existence of paragraph (h)(2) of the
NPRM (76 FR 19710, April 8, 2011).
We agree to provide clarification.
Paragraph (h)(1)(ii) of this AD
(paragraph (h)(2) of the NPRM (76 FR
19710, April 8, 2011)), along with
paragraphs (h)(1)(i) and (h)(1)(iii) of this
AD (paragraphs (h)(1) and (h)(3) of the
NPRM), are located within table 1 to
paragraph (h)(1) of this AD. We have not
changed this AD in this regard.
Request To Allow Use of Certain Hot
Short Protectors (HSPs)
UAL requested the addition of a
paragraph to the NPRM (76 FR 19710,
April 8, 2011) that would allow the use
of an HSP that passed a functional test
described in a manufacturer’s CMM.
UAL noted that paragraph (r) of the
NPRM discusses AWL No. 28–AWL–22,
which specifies that a new unit be used
during replacement of the HSP. UAL
stated that Goodrich’s CMM stated that
the HSP is not repairable, however, the
inclusion of a functional test procedure
seems to indicate that an HSP can be
used if it passes the functional test.
We disagree. AWL No. 28–AWL–22 as
specified in the Boeing 757 MPD
Document revisions required by
paragraph (k)(3) of this AD (paragraph
(l)(3) of the NPRM (76 FR 19710, April
8, 2011)) specifies the use of a new HSP.
An operator’s failure to comply with
that AWL would be a violation of
section 91.403(c) of the Federal Aviation
Regulations (14 CFR 91.403(c)).
However, if an operator wants to
incorporate an alternative AWL that
allows for use of an HSP unit that
passed a functional test, that operator
may request an AMOC under the
provisions of paragraph(s) of this AD.
We have not changed this AD in this
regard.
Request To Revise Instead of Supersede
UAL asked why the FAA is proposing
to supersede AD 2008–10–11,
Amendment 39–15517 (73 FR 25974,
PO 00000
Frm 00019
Fmt 4700

May 8, 2008) instead of revising that
AD. UAL listed 18 revised ADs that
address the same subject for different
model airplanes. UAL stated that
superseding an AD drives many AMOC
requests and could also set up
‘‘compliance traps.’’
We disagree. This AD requires new
actions in addition to those originally
required by AD 2008–10–11,
Amendment 39–15517 (73 FR 25974,
May 8, 2008), while the other ADs that
UAL listed do not require any
additional action. When additional
actions must be mandated, we
supersede the existing AD instead of
revising the AD. No change to this AD
has been made in this regard.
Explanation of Other Changes Made to
This AD
We have re-designated Note 4 of the
NPRM (76 FR 19710, April 8, 2011) as
paragraph (k)(4) of this AD. We have
also reviewed Note 4 of the NPRM and
determined that the reference to
paragraph (k) of this AD may be
removed. Paragraph (k)(4) of this AD is
intended to clarify that this AD does not
require rework of components that had
been maintained using acceptable
methods before the revisions of the
maintenance program, as originally
required by paragraph (g) of AD 2008–
10–11, Amendment 39–15517 (73 FR
25974, May 8, 2008).
We have redesignated Note 1 of the
NPRM (76 FR 19710, April 8, 2011) as
paragraph (c)(2) of this AD, and
paragraph (c) of the NPRM as paragraph
(c)(1) of this AD.
We have revised the paragraph
structure of paragraph (h) of this AD.
Paragraphs (h), (h)(1), (h)(2), and (h)(3)
of the NPRM (76 FR 19710, April 8,
2011) are reidentified as paragraphs
(h)(1), (h)(1)(i), (h)(1)(ii), and (h)(1)(iii)
of this AD, respectively. We have also
revised the heading of table 1 of the
NPRM for more orderly codification
within the Code of Federal Regulations.
We have redesignated Notes 2 and 3
of the NPRM (76 FR 19710, April 8,
2011) as paragraphs (h)(2), and (h)(3) of
this AD, respectively.
We have revised certain headers
throughout this AD.
We have revised the wording in
paragraphs (r)(1) and (r)(2) of this AD
(paragraphs (j) and (t) of the NPRM (76
FR 19710, April 8, 2011); this change
has not changed the intent of these
paragraphs.
We have corrected the definition of
the term ‘‘MPD document’’ throughout
this AD; this change does not affect the
intent of any requirement in this AD.

Conclusion
We reviewed the relevant data,
considered the comments received, and
determined that air safety and the
public interest require adopting the AD
with the changes described previously
and minor editorial changes. We have
determined that these minor changes:
• Are consistent with the intent that
was proposed in the NPRM (76 FR
19710, April 8, 2011) for correcting the
unsafe condition; and
• Do not add any additional burden
upon the public than was already
proposed in the NPRM (76 FR 19710,
April 8, 2011).
We also determined that these
changes will not increase the economic
burden on any operator or increase the
scope of the AD.
Costs of Compliance
There are about 990 airplanes of the
affected design in the worldwide fleet.
The following table provides the
estimated costs for U.S. operators to
comply with this AD.

mstockstill on DSK4VPTVN1PROD with RULES
Authority for This Rulemaking
Title 49 of the United States Code
specifies the FAA’s authority to issue
rules on aviation safety. Subtitle I,
Section 106, describes the authority of
the FAA Administrator. Subtitle VII,
Aviation Programs, describes in more
detail the scope of the Agency’s
authority.
We are issuing this rulemaking under
the authority described in Subtitle VII,
Part A, Subpart III, Section 44701,
‘‘General requirements.’’ Under that
section, Congress charges the FAA with
promoting safe flight of civil aircraft in
air commerce by prescribing regulations
for practices, methods, and procedures
the Administrator finds necessary for
safety in air commerce. This regulation
is within the scope of that authority
because it addresses an unsafe condition
that is likely to exist or develop on
products identified in this rulemaking
action.
Regulatory Findings
We have determined that this AD will
not have federalism implications under
Executive Order 13132. This AD will
not have a substantial direct effect on
the States, on the relationship between
the national government and the States,
or on the distribution of power and
responsibilities among the various
levels of government.
For the reasons discussed above, I
certify that this AD:
(1) Is not a ‘‘significant regulatory
action’’ under Executive Order 12866,
(2) Is not a ‘‘significant rule’’ under
DOT Regulatory Policies and Procedures
(44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation
in Alaska, and
(4) Will not have a significant
economic impact, positive or negative,
on a substantial number of small entities

Adoption of the Amendment
Accordingly, under the authority
delegated to me by the Administrator,
the FAA amends 14 CFR part 39 as
follows:

(c) Applicability
(1) This AD applies to all The Boeing
Company Model 757–200, –200PF, –200CB,
and –300 series airplanes, certificated in any
category.
(2) This AD requires revisions to certain
operator maintenance documents to include
new actions (e.g., inspections) and/or critical
design configuration control limitations
(CDCCLs). Compliance with these actions
and/or CDCCLs is required by 14 CFR
91.403(c). For airplanes that have been
previously modified, altered, or repaired in
the areas addressed by these inspections, the
operator may not be able to accomplish the
actions described in the revisions. In this
situation, to comply with 14 CFR 91.403(c),
the operator must request approval of an
alternative method of compliance (AMOC)
according to paragraph(s) of this AD. The
request should include a description of
changes to the required actions that will
ensure the continued operational safety of
the airplane.

(d) Subject
Air Transport Association (ATA) of
America Code 28: Fuel.
2012–12–15 The Boeing Company:
Amendment 39–17095; Docket No.
FAA–2011–0304; Directorate Identifier
2011–NM–103–AD.
(e) Unsafe Condition
This AD results from a design review of the
fuel tank systems. The Federal Aviation
Administration is issuing this AD to prevent
the potential for ignition sources inside fuel
tanks caused by latent failures, alterations,
repairs, or maintenance actions, which, in
combination with flammable fuel vapors,
could result in a fuel tank explosion and
consequent loss of the airplane.
2. The FAA amends § 39.13 by
removing airworthiness directive (AD)
2008–10–11, Amendment 39–15517 (73
FR 25974, May 8, 2008), and adding the
following new AD:
(a) Effective Date
This airworthiness directive (AD) is
effective August 27, 2012.
(b) Affected ADs
This AD supersedes AD 2008–10–11,
Amendment 39–15517 (73 FR 25974, May 8,
2008). Certain requirements of this AD
terminate certain requirements of AD 2008–
11–07, Amendment 39–15529 (73 FR 30755,
May 29, 2008); AD 2008–06–03, Amendment

AGENCY: Federal Aviation Administration (FAA), DOT.
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: We are superseding an existing airworthiness directive (AD)
for The Boeing Company Model 757 Airplanes. That AD currently requires
revising the Airworthiness Limitations (AWLs) section of the
Instructions for Continued Airworthiness by
[[Page 42965]]
incorporating new limitations for fuel tank systems to satisfy Special
Federal Aviation Regulation No. 88 requirements. That AD also requires
the initial inspection of certain repetitive AWL inspections to phase-
in those inspections, and repair if necessary. This new AD requires
actions that were provided previously as optional actions, and would
require a certain initial inspection to be accomplished for a revised
AWL. This AD was prompted by a report that an AWL required by the
existing AD must be revised. We are issuing this AD to prevent the
potential for ignition sources inside fuel tanks caused by latent
failures, alterations, repairs, or maintenance actions, which, in
combination with flammable fuel vapors, could result in a fuel tank
explosion and consequent loss of the airplane.
DATES: This AD is effective August 27, 2012.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of August 27,
2012.
The Director of the Federal Register approved the incorporation by
reference of a certain other publication listed in this AD as of June

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to supersede airworthiness directive (AD) AD 2008-10-11,
Amendment 39-15517 (73 FR 25974, May 8, 2008). That AD applies to the
specified products. The NPRM published in the Federal Register on April
8, 2011 (76 FR 19710). That NPRM proposed to continue to require
revising the Airworthiness Limitations (AWLs) section of the
Instructions for Continued Airworthiness by incorporating new
limitations for fuel tank systems to satisfy Special Federal Aviation
Regulation No. 88 requirements, and the initial inspection of certain
repetitive AWL inspections to phase-in those inspections, and repair if
necessary. That NPRM also proposed to require actions that were
provided previously as optional actions, and would require a certain
initial inspection to be accomplished for a revised AWL.
Comments
We gave the public the opportunity to participate in developing
this AD. We have considered the comments received. Boeing supports the
NPRM (76 FR 19710, April 8, 2011).
Request To Refer to the Most Recent Revision of Service Information
United Airlines (UAL) requested that paragraph (l) of the NPRM (76
FR 19710, April 8, 2011) be revised to allow use of Boeing Temporary
Revision (TR) 09-010, dated July 2010, to Section 9, ``Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements (CMRs),''
of the Boeing 757 Maintenance Planning Data (MPD) Document, D622N001-9;
or Boeing TR 09-011, dated November 2010, to Section 9, ``Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements (CMRs),''
of the Boeing 757 MPD Document, D622N001-9; to comply with the proposed
requirements of that paragraph.
We infer that the commenter would like the AD to reference the
current revision of the service information. We agree to revise this AD
to refer to the most recent revision. We have revised paragraph (k) of
this AD (paragraph (l) of the NPRM (76 FR 19710, April 8, 2011), and
also paragraphs (h), (l), (m), and (n) of this AD (paragraphs (h), (m),
(n), and (o) of the NPRM, respectively) to reference Boeing TR 09-011,
dated November 2010, to Section 9, ``Airworthiness Limitations (AWLs)
and Certification Maintenance Requirements (CMRs),'' of the Boeing 757
MPD Document, D622N001-9.
Request To Allow Use of Later Revisions to Certain Service Information
UAL requested that additional revisions of service information be
included in paragraphs (s) and (t) of the NPRM (76 FR 19710, April 8,
2011). UAL noted in particular, the MPD revisions approved by the ACO
after publication of AD 2008-10-11, Amendment 39-15517 (73 FR 25974,
May 8, 2008). Since paragraphs (g), (h), and (i) of AD 2008-10-11 allow
the use of a later revision of the MPD that is approved by the Seattle
ACO without requesting an alternative method of compliance (AMOC), UAL
believed that operators that used those later revisions after
publication of AD 2008-10-11, without an AMOC, for the actions required
by paragraphs (g), (h), and (i) of that AD would be in violation of the
NPRM because they would not receive credit for using those revisions.
We agree that for paragraph (h) of this AD (the restated actions of
AD 2008-10-11, Amendment 39-15517 (73 FR 25974, May 8, 2008)), the
following revisions of the MPD are acceptable. Section 9,
``Airworthiness Limitations (AWLs) and Certification Maintenance
Requirements (CMRs),'' of the Boeing 757 MPD Document, D622N001-9,
Revision December 2008; Boeing TR 09-010, dated July 2010, to Section
9, ``Airworthiness Limitations (AWLs) and Certification Maintenance
Requirements (CMRs),'' of Boeing 757 MPD Document, D622N001-9; and
Boeing TR 09-011, dated November 2010, to Section 9, ``Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements (CMRs),''
of the Boeing 757 MPD Document, D622N001-9; are the acceptable
revisions that have been approved after June 12, 2008 (the effective
date of AD 2008-10-11). No AMOC approval is needed to use any of those
three documents. We have revised paragraph (h) of this AD accordingly,
and also paragraphs (k), (l), (m), and (n) of this AD (paragraphs (l),
(m), (n), and (o) of the NPRM (76 FR 19710, April 8, 2011)) to
reference all three MPD revisions that are acceptable for compliance
with the requirements of this AD.
No change is necessary for paragraph (g) of this AD, because
paragraph (k) of this AD (paragraph (l) of the NPRM (76 FR 19710, April
8, 2011)) (which
[[Page 42966]]
terminates the requirements of paragraph (g) of this AD) has been
revised to include those three MPD revisions.
Also, no change is necessary to paragraph (i) of this AD, because
that paragraph does not reference service information. The paragraph
clarifies that after accomplishing paragraphs (g) and (h) of this AD
(except as required by paragraphs (k) and (l) of this AD respectively),
no alternative inspections, inspection intervals, or critical design
configuration control limitations (CDCCLs) are acceptable unless
approved in accordance with the procedures specified in paragraph (s)
of this AD.
Since we have included the MPD revision that was proposed as credit
by paragraph (s) of the NPRM (76 FR 19710, April 8, 2011) as an MPD
revision that is acceptable for compliance with this AD, we have
deleted paragraph (s) of the NPRM (and re-identified paragraph (t) of
the NPRM as paragraph (r)(2) of this AD) from this AD.
We do not agree that any revision to paragraph (r)(2) of this AD
(paragraph (t) of the NPRM (76 FR 19710, April 8, 2011)) is necessary.
Paragraph (r)(2) of this AD gives credit for a certain revision of the
MPD for paragraphs (m) and (n) of this AD (paragraphs (n) and (o) of
the NPRM), which are not a part of the existing actions of AD 2008-10-
11, Amendment 39-15517 (73 FR 25974, May 8, 2008). We have not revised
this AD in this regard.
Request To Revise Wording in Certain AWLs
UAL requested that wording in certain AWLs that refer to ``later
revisions'' of component maintenance manuals (CMMs) be removed. UAL
noted that the FAA removed references to ``a later revision'' of
Section 9 of the Boeing 757 MPD Document, D622N001-9 (referenced as
Boeing TR 09-008, dated March 2008, to Section 9, ``Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements (CMRs),''
of the Boeing 757 MPD Document, D622N001-9, in AD 2008-10-11, Amendment
39-15517 (73 FR 25974, May 8, 2008)), to be consistent with FAA policy
and with Office of the Federal Register regulations for approving
materials that are incorporated by reference. UAL stated that section
51.1(f) of the Code of Federal Regulations (1 CFR 51.1(f)) prohibits
the incorporation by reference of future amendments or revisions of
publications, and because specific revisions of the Boeing 757 MPD
Document, D622N001-9, are incorporated by reference into the Federal
Register, UAL believed that the MPD should also omit language referring
to future revisions of CMMs.
We disagree with the request. Paragraphs (g)(3) and (k)(3)
(paragraph (l)(3) of the NPRM (76 FR 19710, April 8, 2011)) of this AD
do not require operators to comply with applicable AWLs, but instead,
require operators to incorporate applicable AWLs into their maintenance
program. Once those applicable AWLs are incorporated into the
operators' maintenance programs, operators are in compliance with
paragraphs (g)(3) and (k)(3) of this AD. Compliance with the condition
defined in each AWL is required by section 91.403(c) of the Federal
Aviation Regulations (14 CFR 91.403(c)) as stated in Note 1 of the NPRM
(76 FR 19710, April 8, 2011). Because this AD does not mandate
compliance with the AWLs, any documents specified in the AWLs are not
incorporated by reference in the Federal Register, and therefore,
section 51.1(f) of the Code of Federal Regulations (1 CFR 51.1(f)) does
not apply. We have not changed this AD in this regard.
Request To Clarify Differences Between Paragraphs (l)(3), (i), and (p)
of the NPRM (76 FR 19710, April 8, 2011)
UAL requested further clarification in regards to paragraphs (i),
(l)(3), and (p) of the NPRM (76 FR 19710, April 8, 2011). UAL noted
that certain AWLs contain reference to later revisions of component
maintenance manuals (CMMs). However, paragraphs (i) and (p) of the NPRM
state that once certain AWLs are incorporated into the maintenance
program, ``no alternative inspections, intervals, or CDCCLs may be used
unless * * * approved as an AMOC * * *.'' Given this restriction, UAL
believes that as long as certain AWLs specify ``later revisions'' of
certain documents, it would not be possible to comply with paragraphs
(i) and (p) of the NPRM. UAL also asked if every future revision of a
CMM approved by the Seattle ACO would require separate AMOC approval to
satisfy the requirements of paragraphs (i) and (p) of the NPRM.
We agree to provide clarification. There is no conflict between the
requirements of paragraph (k)(3) of this AD (paragraph (l)(3) of the
NPRM (76 FR 19710, April 8, 2011)) and paragraphs (i) and (o) of this
AD. Paragraphs (i) and (o) (paragraphs (i) and (p) of the NPRM) of this
AD prohibit the use of an alternative inspection, inspection interval,
or CDCCL unless it is approved as an AMOC. The intent of paragraphs (i)
and (o) of this AD is to prohibit the use of an alternative AWL without
AMOC approval, as each AWL defines an inspection, inspection interval,
or CDCCL. If an operator desires to use an alternative AWL, such as an
AWL defined in an MPD revision that is different from those specified
in paragraphs (g)(3) and (k)(3) of this AD, that operator must obtain
AMOC approval to use that alternative AWL, as required by paragraphs
(i) and (o) of this AD. Once operators incorporate the AWLs required by
this AD or alternative AWLs that have been approved as an AMOC into
their maintenance program, they are in compliance with the requirements
of paragraphs (g)(3) and (k)(3) of this AD, as applicable. After
incorporation of the AWLs, operators are required to comply with each
AWL by 14 CFR 91.403(c). Operators are in compliance with those AWLs as
long as they use CMM revisions that have been approved by the Seattle
ACO. Therefore, separate AMOC approval is not necessary to use CMM
revisions that have been approved by the Seattle ACO. We have not
changed this AD in this regard.
Request To Consolidate Paragraphs (i) and (p) of the NPRM (76 FR 19710,
April 8, 2011)
UAL requested that we consolidate paragraphs (i) and (p) of the
NPRM (76 FR 19710, April 8, 2011) into a single paragraph. UAL stated
that it found what it considers to be an overlap between paragraphs (i)
and (p) of the NPRM. UAL suggested that consolidating the paragraphs
would streamline the AD and reduce confusion for operators.
We disagree. Paragraph (i) of this AD is a part of the restatement
of the existing requirements of AD 2008-10-11, Amendment 39-15517 (73
FR 25974, May 8, 2008), and is for the restated requirements of
paragraphs (g) and (h) of this AD. Paragraph (o) of this AD (paragraph
(p) of the NPRM (76 FR 19710, April 8, 2011)) is part of the new
requirements of this superseding AD, and is intended to be effective
once the revision required by paragraph (k) of this AD is done. We have
not changed this AD in this regard. However, we have clarified
paragraph (i) of this AD by noting that doing the actions required by
paragraph (k) of this AD is an exception to the requirements of
paragraph (i) of this AD.
Request To Consolidate the Credit Paragraphs
UAL requested that we consolidate paragraphs (j), (s), and (t) of
the NPRM (76 FR 19710, April 8, 2011) into a single paragraph. UAL
requested this
[[Page 42967]]
action for the convenience of providing operators a single paragraph to
reference. In an example that UAL provided, UAL suggested combining
paragraphs (j) and (s) of the NPRM into one sub-paragraph with the same
effective date of June 12, 2008, and paragraph (t) of the NPRM as the
other sub-paragraph with an effective date of ``before the effective
date of this AD.''
We partially agree. Paragraph (s) of the NPRM (76 FR 19710, April
8, 2011) has been deleted as previously discussed. Paragraphs (j) and
(t) of the NPRM can be consolidated. We have removed paragraph (j) of
the NPRM, re-identified subsequent paragraphs, and relocated the
information from paragraph (j) of the NPRM to paragraph (r)(1) of this
AD. The information in paragraph (t) of the NPRM is now in paragraph
(r)(2) of this AD.
Request To Clarify or Revise the Effective Dates in Regards to a
Certain Revision Level of the MPD Document
UAL requested that we revise a sentence in paragraph (h) of the
NPRM (76 FR 19710, April 8, 2011) that reads ``After the effective date
of this AD, only * * * may be used'' to allow 6 months before requiring
operators to use the current revision of the MPD when complying with
the initial inspection requirements of paragraph (h) of the NPRM. UAL
noted that paragraph (h) of the NPRM proposed to require use of Boeing
TR 09-010, dated July 2010, to Section 9, ``Airworthiness Limitations
(AWLs) and Certification Maintenance Requirements (CMRs),'' of Boeing
757 MPD Document, D622N001-9, immediately after the effective date of
the AD, while paragraph (l) of the NPRM would have allowed 6 months to
incorporate the Boeing TR 09-010, dated July 2010, to Section 9,
``Airworthiness Limitations (AWLs) and Certification Maintenance
Requirements (CMRs),'' of Boeing 757 MPD Document, D622N001-9, into the
maintenance program. UAL is concerned about the effect that such a
short compliance time could have on airplanes on which the operator
started the initial inspection (using a previous revision of the MPD)
before the effective date of the AD and completes the inspection after
the effective date of the AD.
We agree to revise paragraph (h) of this AD to allow 6 months after
the effective date of this AD before operators are required to do
initial inspections using Section 9, ``Airworthiness Limitations (AWLs)
and Certification Maintenance Requirements (CMRs),'' of the Boeing 757
MPD Document, D622N001-9, Revision December 2008; Boeing TR 09-010,
dated July 2010, to Section 9, ``Airworthiness Limitations (AWLs) and
Certification Maintenance Requirements (CMRs),'' of Boeing 757 MPD
Document, D622N001-9; or Boeing TR 09-011, dated November 2010, to
Section 9, ``Airworthiness Limitations (AWLs) and Certification
Maintenance Requirements (CMRs),'' of the Boeing 757 MPD Document,
D622N001-9. This change would make paragraphs (h) and (k) of this AD
more consistent with each other.
Request To Confirm Existence of Paragraph (h)(2) of the NPRM (76 FR
19710, April 8, 2011)
UAL stated that it could not confirm the existence of paragraph
(h)(2) of the NPRM (76 FR 19710, April 8, 2011).
We agree to provide clarification. Paragraph (h)(1)(ii) of this AD
(paragraph (h)(2) of the NPRM (76 FR 19710, April 8, 2011)), along with
paragraphs (h)(1)(i) and (h)(1)(iii) of this AD (paragraphs (h)(1) and
(h)(3) of the NPRM), are located within table 1 to paragraph (h)(1) of
this AD. We have not changed this AD in this regard.
Request To Allow Use of Certain Hot Short Protectors (HSPs)
UAL requested the addition of a paragraph to the NPRM (76 FR 19710,
April 8, 2011) that would allow the use of an HSP that passed a
functional test described in a manufacturer's CMM. UAL noted that
paragraph (r) of the NPRM discusses AWL No. 28-AWL-22, which specifies
that a new unit be used during replacement of the HSP. UAL stated that
Goodrich's CMM stated that the HSP is not repairable, however, the
inclusion of a functional test procedure seems to indicate that an HSP
can be used if it passes the functional test.
We disagree. AWL No. 28-AWL-22 as specified in the Boeing 757 MPD
Document revisions required by paragraph (k)(3) of this AD (paragraph
(l)(3) of the NPRM (76 FR 19710, April 8, 2011)) specifies the use of a
new HSP. An operator's failure to comply with that AWL would be a
violation of section 91.403(c) of the Federal Aviation Regulations (14
CFR 91.403(c)). However, if an operator wants to incorporate an
alternative AWL that allows for use of an HSP unit that passed a
functional test, that operator may request an AMOC under the provisions
of paragraph(s) of this AD. We have not changed this AD in this regard.
Request To Revise Instead of Supersede
UAL asked why the FAA is proposing to supersede AD 2008-10-11,
Amendment 39-15517 (73 FR 25974, May 8, 2008) instead of revising that
AD. UAL listed 18 revised ADs that address the same subject for
different model airplanes. UAL stated that superseding an AD drives
many AMOC requests and could also set up ``compliance traps.''
We disagree. This AD requires new actions in addition to those
originally required by AD 2008-10-11, Amendment 39-15517 (73 FR 25974,
May 8, 2008), while the other ADs that UAL listed do not require any
additional action. When additional actions must be mandated, we
supersede the existing AD instead of revising the AD. No change to this
AD has been made in this regard.
Explanation of Other Changes Made to This AD
We have re-designated Note 4 of the NPRM (76 FR 19710, April 8,
2011) as paragraph (k)(4) of this AD. We have also reviewed Note 4 of
the NPRM and determined that the reference to paragraph (k) of this AD
may be removed. Paragraph (k)(4) of this AD is intended to clarify that
this AD does not require rework of components that had been maintained
using acceptable methods before the revisions of the maintenance
program, as originally required by paragraph (g) of AD 2008-10-11,
Amendment 39-15517 (73 FR 25974, May 8, 2008).
We have redesignated Note 1 of the NPRM (76 FR 19710, April 8,
2011) as paragraph (c)(2) of this AD, and paragraph (c) of the NPRM as
paragraph (c)(1) of this AD.
We have revised the paragraph structure of paragraph (h) of this
AD. Paragraphs (h), (h)(1), (h)(2), and (h)(3) of the NPRM (76 FR
19710, April 8, 2011) are reidentified as paragraphs (h)(1), (h)(1)(i),
(h)(1)(ii), and (h)(1)(iii) of this AD, respectively. We have also
revised the heading of table 1 of the NPRM for more orderly
codification within the Code of Federal Regulations.
We have redesignated Notes 2 and 3 of the NPRM (76 FR 19710, April
8, 2011) as paragraphs (h)(2), and (h)(3) of this AD, respectively.
We have revised certain headers throughout this AD.
We have revised the wording in paragraphs (r)(1) and (r)(2) of this
AD (paragraphs (j) and (t) of the NPRM (76 FR 19710, April 8, 2011);
this change has not changed the intent of these paragraphs.
We have corrected the definition of the term ``MPD document''
throughout this AD; this change does not affect the intent of any
requirement in this AD.
[[Page 42968]]
Conclusion
We reviewed the relevant data, considered the comments received,
and determined that air safety and the public interest require adopting
the AD with the changes described previously and minor editorial
changes. We have determined that these minor changes:
Are consistent with the intent that was proposed in the
NPRM (76 FR 19710, April 8, 2011) for correcting the unsafe condition;
and
Do not add any additional burden upon the public than was
already proposed in the NPRM (76 FR 19710, April 8, 2011).
We also determined that these changes will not increase the
economic burden on any operator or increase the scope of the AD.
Costs of Compliance
There are about 990 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs for
U.S. operators to comply with this AD.

Authority for This Rulemaking
Title 49 of the United States Code specifies the FAA's authority to
issue rules on aviation safety. Subtitle I, Section 106, describes the
authority of the FAA Administrator. Subtitle VII, Aviation Programs,
describes in more detail the scope of the Agency's authority.
We are issuing this rulemaking under the authority described in
Subtitle VII, Part A, Subpart III, Section 44701, ``General
requirements.'' Under that section, Congress charges the FAA with
promoting safe flight of civil aircraft in air commerce by prescribing
regulations for practices, methods, and procedures the Administrator
finds necessary for safety in air commerce. This regulation is within
the scope of that authority because it addresses an unsafe condition
that is likely to exist or develop on products identified in this
rulemaking action.
Regulatory Findings
We have determined that this AD will not have federalism
implications under Executive Order 13132. This AD will not have a
substantial direct effect on the States, on the relationship between
the national government and the States, or on the distribution of power
and responsibilities among the various levels of government.
For the reasons discussed above, I certify that this AD:
(1) Is not a ``significant regulatory action'' under Executive
Order 12866,
(2) Is not a ``significant rule'' under DOT Regulatory Policies and
Procedures (44 FR 11034, February 26, 1979),
(3) Will not affect intrastate aviation in Alaska, and
(4) Will not have a significant economic impact, positive or
negative, on a substantial number of small entities under the criteria
of the Regulatory Flexibility Act.
List of Subjects in 14 CFR Part 39
Air transportation, Aircraft, Aviation safety, Incorporation by
reference, Safety.
Adoption of the Amendment
Accordingly, under the authority delegated to me by the
Administrator, the FAA amends 14 CFR part 39 as follows:
PART 39--AIRWORTHINESS DIRECTIVES
0
1. The authority citation for part 39 continues to read as follows:
Authority: 49 U.S.C. 106(g), 40113, 44701.
Sec. 39.13 [Amended]
0
2. The FAA amends Sec. 39.13 by removing airworthiness directive (AD)
2008-10-11, Amendment 39-15517 (73 FR 25974, May 8, 2008), and adding
the following new AD:
2012-12-15 The Boeing Company: Amendment 39-17095; Docket No. FAA-
2011-0304; Directorate Identifier 2011-NM-103-AD.
(a) Effective Date
This airworthiness directive (AD) is effective August 27, 2012.
(b) Affected ADs
This AD supersedes AD 2008-10-11, Amendment 39-15517 (73 FR
25974, May 8, 2008). Certain requirements of this AD terminate
certain requirements of AD 2008-11-07, Amendment 39-15529 (73 FR
30755, May 29, 2008); AD 2008-06-03, Amendment 39-15415 (73 FR
13081, March 12, 2008); and AD 2009-06-20, Amendment 39-15857 (74 FR
12236, March 24, 2009).
(c) Applicability
(1) This AD applies to all The Boeing Company Model 757-200, -
200PF, -200CB, and -300 series airplanes, certificated in any
category.
(2) This AD requires revisions to certain operator maintenance
documents to include new actions (e.g., inspections) and/or critical
design configuration control limitations (CDCCLs). Compliance with
these actions and/or CDCCLs is required by 14 CFR 91.403(c). For
airplanes that have been previously modified, altered, or repaired
in the areas addressed by these inspections, the operator may not be
able to accomplish the actions described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval of an alternative method of compliance (AMOC)
according to paragraph(s) of this AD. The request should include a
description of changes to the required actions that will ensure the
continued operational safety of the airplane.
(d) Subject
Air Transport Association (ATA) of America Code 28: Fuel.
(e) Unsafe Condition
This AD results from a design review of the fuel tank systems.
The Federal Aviation Administration is issuing this AD to prevent
the potential for ignition sources inside fuel tanks caused by
latent failures, alterations, repairs, or maintenance actions,
which, in combination with flammable fuel vapors, could result in a
fuel tank explosion and consequent loss of the airplane.
(f) Compliance
You are responsible for having the actions required by this AD
performed within the compliance times specified, unless the actions
have already been done.
(g) Retained Revision of Airworthiness Limitations (AWLs) Section
This paragraph restates the requirements of paragraph (g) of AD
2008-10-11, Amendment 39-15517 (73 FR 25974, May 8, 2008). Before
December 16, 2008, revise the
[[Page 42969]]
AWLs section of the Instructions for Continued Airworthiness (ICA)
by incorporating the information in the subsections specified in
paragraphs (g)(1) through (g)(3) of this AD into the maintenance
planning data (MPD) document; except that the initial inspections
specified in table 1 to paragraph (h)(1) of this AD must be done at
the compliance times specified in table 1 to paragraph (h)(1) of
this AD. Accomplishing the requirements of paragraph (k) of this AD
terminates the requirements of this paragraph.
(1) Subsection E, ``AIRWORTHINESS LIMITATIONS--FUEL SYSTEMS,''
of Boeing Temporary Revision (TR) 09-008, dated March 2008, to
Section 9, ``Airworthiness Limitations (AWLs) and Certification

(3) Subsection G, ``AIRWORTHINESS LIMITATIONS--FUEL SYSTEM
AWLs,'' AWLs No. 28-AWL-01 through No. 28-AWL-24 inclusive, of
Boeing TR 09-008, dated March 2008, to Section 9, ``Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements
(CMRs),'' of the Boeing 757 MPD Document, D622N001-9. As an optional
action, AWLs No. 28-AWL-25 and No. 28-AWL-26, as identified in
Subsection G of Boeing TR 09-008, dated March 2008, to Section 9,
``Airworthiness Limitations (AWLs) and Certification Maintenance
Requirements (CMRs),'' of the Boeing 757 MPD Document, D622N001-9,
also may be incorporated into the AWLs section of the ICA.
(h) Retained Initial Inspections and Repair, With Revised Service
Information
(1) This paragraph restates the requirements of paragraph (h) of
AD 2008-10-11, Amendment 39-15517 (73 FR 25974, May 8, 2008). Do the
inspections specified in table 1 to paragraph (h)(1) of this AD at
the compliance time identified in table 1 to paragraph (h)(1) of
this AD, and repair any discrepancy, in accordance with Subsection G
of Boeing TR 09-008, dated March 2008, to Section 9, ``Airworthiness
Limitations (AWLs) and Certification Maintenance Requirements
(CMRs),'' of the Boeing 757 MPD Document, D622N001-9; Section 9,

Requirements (CMRs),'' of the Boeing 757 MPD Document, D622N001-9;
except as required by paragraph (n) of this AD. The repair must be
done before further flight. Accomplishing the inspections identified
in table 1 to paragraph (h)(1) of this AD as part of a maintenance
program before the applicable compliance time specified in table 1
paragraph (h)(1) of this AD constitutes compliance with the
requirements of this paragraph. As of 6 months after the effective

(4) Notwithstanding any other maintenance or operational
requirements, components that have been identified as airworthy or
installed on the affected airplanes before the revision of the
maintenance program, as required by paragraph (g) of this AD, do not
need to be reworked in accordance with the CDCCLs. However, once the
maintenance program has been revised, future maintenance actions on
these components must be done in accordance with the CDCCLs.
