cprice-sewell on PROD1PC69 with RULES
SUMMARY: We are adopting a new
airworthiness directive (AD) for all
Lockheed Model L–1011 series
airplanes. This AD requires revising the
FAA-approved maintenance program by
incorporating new airworthiness
limitations for fuel tank systems to
satisfy Special Federal Aviation
Regulation No. 88 requirements. This
AD also requires the accomplishment of
certain fuel system modifications, the
initial inspections of certain repetitive
fuel system limitations to phase in those
inspections, and repair if necessary.
This AD results from a design review of
the fuel tank systems. 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.

Jkt 214001
We issued a notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness
directive (AD) that would apply to all
Lockheed Model L–1011 series
airplanes. That NPRM was published in
the Federal Register on February 20,
2008 (73 FR 9235). That NPRM
proposed to require revising the FAAapproved maintenance program by
incorporating new airworthiness
limitations (AWLs) for fuel tank systems
to satisfy Special Federal Aviation
Regulation No. 88 (‘‘SFAR 88’’)
requirements. That NPRM also proposed
to require the accomplishment of certain
fuel system modifications, the initial
inspections of certain repetitive fuel
system limitations (FSLs) to phase in
those inspections, and repair if
necessary.
Comments
We gave the public the opportunity to
participate in developing this AD. We
considered the comments received from
the one commenter.

Request To Supersede AD 2001–08–21,
Amendment 39–12198
ATA Airlines requests that we revise
the NPRM by removing the proposed
requirement to accomplish the FSL
specified in paragraph 2.B.(1)(d) of
Lockheed Service Bulletin 093–28–098,
Revision 1, dated January 22, 2008.
(Lockheed Service Bulletin 093–28–098,
Revision 1, refers to Lockheed Service
Bulletin 093–28–094, Revision 1, dated
June 23, 2006, for accomplishing that
FSL.) The commenter further requests
that we instead issue a separate
rulemaking action to supersede AD
2001–08–21 (66 FR 21072, April 27,
2001) to require the accomplishment of
Revision 1 of Lockheed Service Bulletin
093–28–094. (As stated in the NPRM,
AD 2001–08–21 requires the
accomplishment of the original issue of
Lockheed Service Bulletin 093–28–094,
dated March 3, 2000, but more work is
necessary for Revision 1 of the service
bulletin.)
We agree that it is more appropriate
to require the accomplishment of
Revision 1 of Lockheed Service Bulletin
093–28–094 by superseding AD 2001–
08–21. Our current policy specifies that,
whenever a ‘‘substantive change’’ is
made to an existing AD that imposes a
new burden, we must supersede the AD.
‘‘Substantive changes’’ are those made
to any instruction or reference that
affects the substance of the AD.
Substantive changes include part
numbers, service bulletin and manual
references, compliance times,
applicability, methods of compliance,
corrective action, inspection
requirements, and effective dates. We
consider the changes in Revision 1 of
the service bulletin to be substantive.
Therefore, we have revised paragraphs
(h) and (i) and Table 2 of this AD by
removing references to paragraph
2.B.(1)(d) and Lockheed Service Bulletin
093–28–094. Further, we will consider
superseding AD 2001–08–21 with a
separate rulemaking action.
Request To Extend the Compliance
Time for Certain Actions
ATA Airlines requests that we extend
the compliance time for accomplishing
the FSLs in paragraphs 2.B.(1)(d),
2.B.(1)(e), 2.B.(1)(f), and 2.B.(1)(g) of
Lockheed Service Bulletin 093–28–098,
Revision 1, dated January 22, 2008, to
the following: on or before the next
heavy maintenance inspection after the
effective date of the AD, but not to
exceed 60 months after the effective
date of the AD. The commenter
recommends revising the compliance
time by either adding a compliance
time, initial threshold, and grace period
E:\FR\FM\21MYR1.SGM
21MYR1
cprice-sewell on PROD1PC69 with RULES
Federal Register / Vol. 73, No. 99 / Wednesday, May 21, 2008 / Rules and Regulations
to Table 2 of the NPRM, or removing
Table 2 from the NPRM and issuing
separate rulemaking actions to address
those FSLs. The commenter also
requests that we include a note in the
AD to define a heavy maintenance
inspection as equivalent to a ‘‘D’’ check
and similar to the definition in the
Lockheed L–1011 Maintenance Review
Board Report, dated March 1, 1998.
As justification for its request, the
commenter states that the NPRM is
inconsistent with other rulemaking
actions addressing other airplane
models. The commenter also states that
those other rulemaking actions are
consistent with the guidance in FAA
Policy Memorandum PS–ANM112–05–
001, ‘‘Policy Statement on Process for
Developing SFAR 88–Related
Instructions for Maintenance and
Inspection of Fuel Tank Systems,’’ dated
October 6, 2004. In support of its
position, the commenter refers to
paragraphs 3.D, 3.D.1, and 4 of that
policy memorandum, and to the ‘‘FourElement Unsafe Condition Evaluation
Criteria’’ section of FAA Policy
Memorandum PS–ANM100–2003–112–
15, ‘‘SFAR 88—Mandatory Action
Design Criteria,’’ dated February 25,
2003. The commenter contends that
each identified unsafe condition and the
AWL changes should be issued as
separate rulemaking actions.
The commenter also contends that it
would be unduly and
disproportionately impacted by the
proposed requirements of the NPRM.
The commenter states that, for other
airplane models, we have issued
separate rulemaking actions to address
design changes and the incorporation of
AWLs for fuel tank systems into the
FAA-approved maintenance program.
The commenter also states that, in some
instances, we have provided a
compliance time of up to 5 years for
accomplishing the design changes. The
commenter, therefore, asserts that
requiring the accomplishment of the
design changes identified in Table 2 of
the NPRM by December 16, 2008, is a
substantial, immediate burden.
The commenter also asserts that
paragraph (h) of the NPRM effectively
makes the service bulletins identified in
Table 2 of the NPRM retroactively
applicable. The commenter notes that
Table 2 does not include the compliance
times recommended in those service
bulletins. ATA Airlines believes that, as
written, the NPRM would effectively
make the compliance recommendation
of up to 2-year-old service documents
rule. As an example, the commenter
points to Lockheed Service Bulletin
093–28–096, dated June 8, 2004, which
recommends doing the initial inspection
VerDate Aug<31>2005
14:17 May 20, 2008
Jkt 214001
of the wiring harnesses of the No. 1 and
No. 3 engine tank valves on or before
the next heavy maintenance inspection,
but not to exceed 5 years from the date
of the service bulletin. That service
bulletin also recommends revising the
maintenance planning documentation to
require repeating the inspection at
intervals not to exceed 10 years from the
date of the last inspection. The
commenter states that, upon issuance of
the final rule, an operator is at risk of
non-compliance, since it is possible for
an airplane to have undergone a heavy
maintenance inspection between
publication of the service bulletin and
the effective date of the AD without
having accomplished the actions
specified in the service bulletin.
We agree to extend the compliance
time for accomplishing the design
changes identified in paragraphs
2.B.(1)(d), 2.B.(1)(e), 2.B.(1)(f), and
2.B.(1)(g) of Lockheed Service Bulletin
093–28–098, Revision 1. We have added
a new paragraph (h)(2) specifying that
the FSLs in paragraphs 2.B.(1)(e),
2.B.(1)(f), and 2.B.(1)(g) must be done
within 60 months after the effective date
of this AD. As stated previously, we
have removed the requirement to
accomplish the FSL in paragraph
2.B.(1)(d) of Lockheed Service Bulletin
093–28–098, Revision 1.
However, we disagree with issuing
separate ADs to address the other design
changes identified in Table 2 of this AD.
The policy memorandum to which the
commenter refers to does not specify
that the design changes must be
addressed by separate rulemaking
actions. We also point out that when the
compliance time in an AD differs from
the recommended compliance time in a
service bulletin, operators are required
to comply with the compliance time
specified in the AD, not the service
bulletin. We have not changed this AD
in this regard.
Request To Extend the Compliance
Time of Paragraph (g)
ATA Airlines requests that we extend
the compliance time by 1 year to
December 16, 2009 in paragraph (g) of
the NPRM. The commenter states that
the airplane manufacturers of other
airplane models have provided
comprehensive data to support
operators in complying with a
compliance date of December 16, 2008.
As an example, the commenter refers to
Docket Nos. FAA–2006–26710, FAA–
2007–28383, and FAA–2007–28384
published on the Internet at https://
www.regulations.gov. The commenter
states that those NPRMs all refer to
comprehensive maintenance planning
documents provided by the airplane
PO 00000
Frm 00025
Fmt 4700
Sfmt 4700
29411
manufacturer, and that those NPRMs
provide explicit thresholds and grace
periods for accomplishing many of the
AWLs for fuel tank systems. The
commenter also states that the airplane
manufacturer either has or is providing
comprehensive revisions to the AWLs
section of the Instructions for Continued
Airworthiness (ICA) to address critical
design configuration control limitations
(CDCCLs) and other SFAR 88 findings.
The commenter asserts that Lockheed
has not provided the same level of
support, which substantially increases
the burden on operators. The
commenter believes that, as a result of
the manner and timeliness of the data
provided for the Model L–1011 series
airplanes, it is appropriate and
justifiable to provide a 12-month grace
period for operators to amend their
maintenance programs.
We disagree with extending the
compliance time for paragraph (g) of
this AD. We have determined that
Lockheed has met the minimum
requirements for supporting operators in
complying with the SFAR 88
requirements. Further, in other similar
NPRMs for other airplane models, we
have not provided a grace period for
revising the FAA-approved maintenance
program or the AWLs section of ICA, as
applicable, to incorporate AWLs for fuel
tank systems. As stated in the preambles
of those NPRMs, we have already issued
regulations that require operators to
revise their maintenance/inspection
programs to address fuel tank safety
issues. The compliance date for these
regulations is December 16, 2008. To
provide for efficient and coordinated
implementation of these regulations and
those NPRMs, we are using this same
compliance date. We have not changed
this AD in this regard.
Request To Extend the Comment Period
ATA Airlines requests that we extend
the comment period for a minimum of
30 days. As justification, the commenter
states that Lockheed Service Bulletin
093–28–098, Revision 1, dated January
22, 2008, was not available to operators
until 9 days after the NPRM was
published in the Federal Register.
We disagree with extending the
comment period. We have attempted to
contact this commenter to better
understand its needs and rationale with
regard to extending the comment
period. However, we have been unable
to reach the commenter after numerous
attempts. To further delay this action
would be inappropriate, since we have
determined that an unsafe condition
exists and it must be addressed to
ensure continued safety.

Federal Register / Vol. 73, No. 99 / Wednesday, May 21, 2008 / Rules and Regulations
Request To Revise Paragraph (b)
ATA Airlines notes that paragraph (b)
of the NPRM specifies that no other
airworthiness directives are affected by
the NPRM. The commenter believes that
this is incorrect because Lockheed
Service Bulletin 093–28–098, Revision
1, dated January 22, 2008, refers to AD
80–25–04, amendment 39–3983 (45 FR
79011, November 28, 1980); AD 99–24–
12, amendment 39–11436 (64 FR 66756,
November 30, 1999); and AD 2001–08–
21. (AD 80–25–04 requires
accomplishing the actions specified in
Lockheed Service Bulletin 093–28–062,
Revision 1, dated August 20, 1980. AD
99–24–12 requires accomplishing the
actions specified in Lockheed Service
Bulletin 093–28–093, Revision 1, dated
February 8, 1999. AD 2001–08–21
requires accomplishing the actions
specified in Lockheed Service Bulletin
093–28–094, dated March 3, 2000.) The
commenter states that AD 2001–08–21
should be identified as a superseded
AD, according to paragraph 121.b. of
Section 12 of the ‘‘Airworthiness
Directives Manual,’’ FAA–IR–M–
8040.1A.
We infer the commenter requests that
we revise paragraph (b) of this AD to
specify that this AD is related to AD 80–
25–04 and AD 99–24–12, and that it
supersedes AD 2001–08–21. We
disagree with revising paragraph (b) of
this AD. Paragraph (b) of an AD is
reserved for referencing any previously
issued AD that is revised or superseded
by a new AD. As stated previously, we
will consider superseding AD 2001–08–
21 with a separate rulemaking action.
No change to this AD is necessary in
this regard.
Change Made to This AD
We have revised paragraph (g) of this
AD to require revising the FAAapproved maintenance program to
incorporate the FSLs and CDCCLs
specified in Lockheed Service Bulletin
093–28–098, Revision 1, except as
provided by paragraphs (g)(1), (g)(2),
and (h) of this AD. In the NPRM, we
inadvertently omitted reference to
paragraph (h).
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.
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 108 airplanes of the
affected design in the worldwide fleet.

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

§ 39.13
[Amended]
2. The FAA amends § 39.13 by adding
the following new AD:
I
2008–11–02 Lockheed: Amendment 39–
15524. Docket No. FAA–2008–0181;
Directorate Identifier 2007–NM–180–AD.
Effective Date
(a) This airworthiness directive (AD) is
effective June 25, 2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Lockheed Model
L–1011 series airplanes, certificated in any
category.
Note 1: This AD requires revisions to
certain operator maintenance documents to
include new inspections. Compliance with
these inspections 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
inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c),
the operator must request approval for an
alternative method of compliance (AMOC) in
accordance with paragraph (k) of this AD.
The request should include a description of
changes to the required inspections that will
ensure the continued operational safety of
the airplane.
Unsafe Condition
(d) This AD results from a design review
of the fuel tank systems. 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.
Compliance
(e) You are responsible for having the
actions required by this AD performed within
the compliance times specified, unless the
actions have already been done.
Service Bulletin Reference
(f) The term ‘‘service bulletin,’’ as used in
this AD, means the Accomplishment
Instructions of Lockheed Service Bulletin
093–28–098, Revision 1, dated January 22,
2008.
Maintenance Program Revision
(g) Before December 16, 2008, revise the
FAA-approved maintenance program to
incorporate the fuel system limitations (FSLs)
specified in paragraphs 2.B.(1)(b), 2.B.(1)(e),
2.B.(1)(f), and 2.B.(1)(g) of the service
bulletin, and the critical design configuration
29413
control limitations (CDCCLs) specified in
paragraph 2.C. of the service bulletin; except
as provided by paragraphs (g)(1), (g)(2), and
(h) of this AD.
(1) Where the FSLs specify to inspect, this
AD would require doing a general visual
inspection.
Note 2: For the purposes of this AD, a
general visual inspection is: ‘‘A visual
examination of an interior or exterior area,
installation, or assembly to detect obvious
damage, failure, or irregularity. This level of
inspection is made from within touching
distance unless otherwise specified. A mirror
may be necessary to ensure visual access to
all surfaces in the inspection area. This level
of inspection is made under normally
available lighting conditions such as
daylight, hangar lighting, flashlight, or
droplight and may require removal or
opening of access panels or doors. Stands,
ladders, or platforms may be required to gain
proximity to the area being checked.’’
(2) For the CDCCLs specified in paragraphs
2.C.(2)(c), 2.C.(2)(d), and 2.C.(15)(a) of the
service bulletin, do the applicable actions
using a method approved in accordance with
the procedures specified in paragraph (k) of
this AD. The applicable service information
listed in Table 1 of this AD is one approved
method.

SUPPLEMENTARY INFORMATION:
Discussion
We issued a notice of proposed rulemaking (NPRM) to amend 14 CFR
part 39 to include an airworthiness directive (AD) that would apply to
all Lockheed Model L-1011 series airplanes. That NPRM was published in
the Federal Register on February 20, 2008 (73 FR 9235). That NPRM
proposed to require revising the FAA-approved maintenance program by
incorporating new airworthiness limitations (AWLs) for fuel tank
systems to satisfy Special Federal Aviation Regulation No. 88 (``SFAR
88'') requirements. That NPRM also proposed to require the
accomplishment of certain fuel system modifications, the initial
inspections of certain repetitive fuel system limitations (FSLs) to
phase in those inspections, and repair if necessary.
Comments
We gave the public the opportunity to participate in developing
this AD. We considered the comments received from the one commenter.
Request To Supersede AD 2001-08-21, Amendment 39-12198
ATA Airlines requests that we revise the NPRM by removing the
proposed requirement to accomplish the FSL specified in paragraph
2.B.(1)(d) of Lockheed Service Bulletin 093-28-098, Revision 1, dated
January 22, 2008. (Lockheed Service Bulletin 093-28-098, Revision 1,
refers to Lockheed Service Bulletin 093-28-094, Revision 1, dated June
23, 2006, for accomplishing that FSL.) The commenter further requests
that we instead issue a separate rulemaking action to supersede AD
2001-08-21 (66 FR 21072, April 27, 2001) to require the accomplishment
of Revision 1 of Lockheed Service Bulletin 093-28-094. (As stated in
the NPRM, AD 2001-08-21 requires the accomplishment of the original
issue of Lockheed Service Bulletin 093-28-094, dated March 3, 2000, but
more work is necessary for Revision 1 of the service bulletin.)
We agree that it is more appropriate to require the accomplishment
of Revision 1 of Lockheed Service Bulletin 093-28-094 by superseding AD
2001-08-21. Our current policy specifies that, whenever a ``substantive
change'' is made to an existing AD that imposes a new burden, we must
supersede the AD. ``Substantive changes'' are those made to any
instruction or reference that affects the substance of the AD.
Substantive changes include part numbers, service bulletin and manual
references, compliance times, applicability, methods of compliance,
corrective action, inspection requirements, and effective dates. We
consider the changes in Revision 1 of the service bulletin to be
substantive. Therefore, we have revised paragraphs (h) and (i) and
Table 2 of this AD by removing references to paragraph 2.B.(1)(d) and
Lockheed Service Bulletin 093-28-094. Further, we will consider
superseding AD 2001-08-21 with a separate rulemaking action.
Request To Extend the Compliance Time for Certain Actions
ATA Airlines requests that we extend the compliance time for
accomplishing the FSLs in paragraphs 2.B.(1)(d), 2.B.(1)(e),
2.B.(1)(f), and 2.B.(1)(g) of Lockheed Service Bulletin 093-28-098,
Revision 1, dated January 22, 2008, to the following: on or before the
next heavy maintenance inspection after the effective date of the AD,
but not to exceed 60 months after the effective date of the AD. The
commenter recommends revising the compliance time by either adding a
compliance time, initial threshold, and grace period
[[Page 29411]]
to Table 2 of the NPRM, or removing Table 2 from the NPRM and issuing
separate rulemaking actions to address those FSLs. The commenter also
requests that we include a note in the AD to define a heavy maintenance
inspection as equivalent to a ``D'' check and similar to the definition
in the Lockheed L-1011 Maintenance Review Board Report, dated March 1,
1998.
As justification for its request, the commenter states that the
NPRM is inconsistent with other rulemaking actions addressing other
airplane models. The commenter also states that those other rulemaking
actions are consistent with the guidance in FAA Policy Memorandum PS-
ANM112-05-001, ``Policy Statement on Process for Developing SFAR 88-
Related Instructions for Maintenance and Inspection of Fuel Tank
Systems,'' dated October 6, 2004. In support of its position, the
commenter refers to paragraphs 3.D, 3.D.1, and 4 of that policy
memorandum, and to the ``Four-Element Unsafe Condition Evaluation
Criteria'' section of FAA Policy Memorandum PS-ANM100-2003-112-15,
``SFAR 88--Mandatory Action Design Criteria,'' dated February 25, 2003.
The commenter contends that each identified unsafe condition and the
AWL changes should be issued as separate rulemaking actions.
The commenter also contends that it would be unduly and
disproportionately impacted by the proposed requirements of the NPRM.
The commenter states that, for other airplane models, we have issued
separate rulemaking actions to address design changes and the
incorporation of AWLs for fuel tank systems into the FAA-approved
maintenance program. The commenter also states that, in some instances,
we have provided a compliance time of up to 5 years for accomplishing
the design changes. The commenter, therefore, asserts that requiring
the accomplishment of the design changes identified in Table 2 of the
NPRM by December 16, 2008, is a substantial, immediate burden.
The commenter also asserts that paragraph (h) of the NPRM
effectively makes the service bulletins identified in Table 2 of the
NPRM retroactively applicable. The commenter notes that Table 2 does
not include the compliance times recommended in those service
bulletins. ATA Airlines believes that, as written, the NPRM would
effectively make the compliance recommendation of up to 2-year-old
service documents rule. As an example, the commenter points to Lockheed
Service Bulletin 093-28-096, dated June 8, 2004, which recommends doing
the initial inspection of the wiring harnesses of the No. 1 and No. 3
engine tank valves on or before the next heavy maintenance inspection,
but not to exceed 5 years from the date of the service bulletin. That
service bulletin also recommends revising the maintenance planning
documentation to require repeating the inspection at intervals not to
exceed 10 years from the date of the last inspection. The commenter
states that, upon issuance of the final rule, an operator is at risk of
non-compliance, since it is possible for an airplane to have undergone
a heavy maintenance inspection between publication of the service
bulletin and the effective date of the AD without having accomplished
the actions specified in the service bulletin.
We agree to extend the compliance time for accomplishing the design
changes identified in paragraphs 2.B.(1)(d), 2.B.(1)(e), 2.B.(1)(f),
and 2.B.(1)(g) of Lockheed Service Bulletin 093-28-098, Revision 1. We
have added a new paragraph (h)(2) specifying that the FSLs in
paragraphs 2.B.(1)(e), 2.B.(1)(f), and 2.B.(1)(g) must be done within
60 months after the effective date of this AD. As stated previously, we
have removed the requirement to accomplish the FSL in paragraph
2.B.(1)(d) of Lockheed Service Bulletin 093-28-098, Revision 1.
However, we disagree with issuing separate ADs to address the other
design changes identified in Table 2 of this AD. The policy memorandum
to which the commenter refers to does not specify that the design
changes must be addressed by separate rulemaking actions. We also point
out that when the compliance time in an AD differs from the recommended
compliance time in a service bulletin, operators are required to comply
with the compliance time specified in the AD, not the service bulletin.
We have not changed this AD in this regard.
Request To Extend the Compliance Time of Paragraph (g)
ATA Airlines requests that we extend the compliance time by 1 year
to December 16, 2009 in paragraph (g) of the NPRM. The commenter states
that the airplane manufacturers of other airplane models have provided
comprehensive data to support operators in complying with a compliance
date of December 16, 2008. As an example, the commenter refers to
Docket Nos. FAA-2006-26710, FAA-2007-28383, and FAA-2007-28384
published on the Internet at https://www.regulations.gov. The commenter
states that those NPRMs all refer to comprehensive maintenance planning
documents provided by the airplane manufacturer, and that those NPRMs
provide explicit thresholds and grace periods for accomplishing many of
the AWLs for fuel tank systems. The commenter also states that the
airplane manufacturer either has or is providing comprehensive
revisions to the AWLs section of the Instructions for Continued
Airworthiness (ICA) to address critical design configuration control
limitations (CDCCLs) and other SFAR 88 findings. The commenter asserts
that Lockheed has not provided the same level of support, which
substantially increases the burden on operators. The commenter believes
that, as a result of the manner and timeliness of the data provided for
the Model L-1011 series airplanes, it is appropriate and justifiable to
provide a 12-month grace period for operators to amend their
maintenance programs.
We disagree with extending the compliance time for paragraph (g) of
this AD. We have determined that Lockheed has met the minimum
requirements for supporting operators in complying with the SFAR 88
requirements. Further, in other similar NPRMs for other airplane
models, we have not provided a grace period for revising the FAA-
approved maintenance program or the AWLs section of ICA, as applicable,
to incorporate AWLs for fuel tank systems. As stated in the preambles
of those NPRMs, we have already issued regulations that require
operators to revise their maintenance/inspection programs to address
fuel tank safety issues. The compliance date for these regulations is
December 16, 2008. To provide for efficient and coordinated
implementation of these regulations and those NPRMs, we are using this
same compliance date. We have not changed this AD in this regard.
Request To Extend the Comment Period
ATA Airlines requests that we extend the comment period for a
minimum of 30 days. As justification, the commenter states that
Lockheed Service Bulletin 093-28-098, Revision 1, dated January 22,
2008, was not available to operators until 9 days after the NPRM was
published in the Federal Register.
We disagree with extending the comment period. We have attempted to
contact this commenter to better understand its needs and rationale
with regard to extending the comment period. However, we have been
unable to reach the commenter after numerous attempts. To further delay
this action would be inappropriate, since we have determined that an
unsafe condition exists and it must be addressed to ensure continued
safety.
[[Page 29412]]
Request To Revise Paragraph (b)
ATA Airlines notes that paragraph (b) of the NPRM specifies that no
other airworthiness directives are affected by the NPRM. The commenter
believes that this is incorrect because Lockheed Service Bulletin 093-
28-098, Revision 1, dated January 22, 2008, refers to AD 80-25-04,
amendment 39-3983 (45 FR 79011, November 28, 1980); AD 99-24-12,
amendment 39-11436 (64 FR 66756, November 30, 1999); and AD 2001-08-21.
(AD 80-25-04 requires accomplishing the actions specified in Lockheed
Service Bulletin 093-28-062, Revision 1, dated August 20, 1980. AD 99-
24-12 requires accomplishing the actions specified in Lockheed Service
Bulletin 093-28-093, Revision 1, dated February 8, 1999. AD 2001-08-21
requires accomplishing the actions specified in Lockheed Service
Bulletin 093-28-094, dated March 3, 2000.) The commenter states that AD
2001-08-21 should be identified as a superseded AD, according to
paragraph 121.b. of Section 12 of the ``Airworthiness Directives
Manual,'' FAA-IR-M-8040.1A.
We infer the commenter requests that we revise paragraph (b) of
this AD to specify that this AD is related to AD 80-25-04 and AD 99-24-
12, and that it supersedes AD 2001-08-21. We disagree with revising
paragraph (b) of this AD. Paragraph (b) of an AD is reserved for
referencing any previously issued AD that is revised or superseded by a
new AD. As stated previously, we will consider superseding AD 2001-08-
21 with a separate rulemaking action. No change to this AD is necessary
in this regard.
Change Made to This AD
We have revised paragraph (g) of this AD to require revising the
FAA-approved maintenance program to incorporate the FSLs and CDCCLs
specified in Lockheed Service Bulletin 093-28-098, Revision 1, except
as provided by paragraphs (g)(1), (g)(2), and (h) of this AD. In the
NPRM, we inadvertently omitted reference to paragraph (h).
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. 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 108 airplanes of the affected design in the
worldwide fleet. The following table provides the estimated costs, at
an average labor rate of $80 per work hour, 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
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), and
(3) 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.
You can find our regulatory evaluation and the estimated costs of
compliance in the AD Docket.

2. The FAA amends Sec. 39.13 by adding the following new AD:
2008-11-02 Lockheed: Amendment 39-15524. Docket No. FAA-2008-0181;
Directorate Identifier 2007-NM-180-AD.
Effective Date
(a) This airworthiness directive (AD) is effective June 25,
2008.
Affected ADs
(b) None.
Applicability
(c) This AD applies to all Lockheed Model L-1011 series
airplanes, certificated in any category.
Note 1: This AD requires revisions to certain operator
maintenance documents to include new inspections. Compliance with
these inspections 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 inspections described in the revisions. In this
situation, to comply with 14 CFR 91.403(c), the operator must
request approval for an alternative method of compliance (AMOC) in
accordance with paragraph (k) of this AD. The request should include
a description of changes to the required inspections that will
ensure the continued operational safety of the airplane.
Unsafe Condition
(d) This AD results from a design review of the fuel tank
systems. 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.
Compliance
(e) You are responsible for having the actions required by this
AD performed within the compliance times specified, unless the

(f) The term ``service bulletin,'' as used in this AD, means the
Accomplishment Instructions of Lockheed Service Bulletin 093-28-098,
Revision 1, dated January 22, 2008.
Maintenance Program Revision
(g) Before December 16, 2008, revise the FAA-approved
maintenance program to incorporate the fuel system limitations
(FSLs) specified in paragraphs 2.B.(1)(b), 2.B.(1)(e), 2.B.(1)(f),
and 2.B.(1)(g) of the service bulletin, and the critical design
configuration control limitations (CDCCLs) specified in paragraph
2.C. of the service bulletin; except as provided by paragraphs
(g)(1), (g)(2), and (h) of this AD.
(1) Where the FSLs specify to inspect, this AD would require
doing a general visual inspection.
Note 2: For the purposes of this AD, a general visual inspection
is: ``A visual examination of an interior or exterior area,
installation, or assembly to detect obvious damage, failure, or
irregularity. This level of inspection is made from within touching
distance unless otherwise specified. A mirror may be necessary to
ensure visual access to all surfaces in the inspection area. This
level of inspection is made under normally available lighting
conditions such as daylight, hangar lighting, flashlight, or
droplight and may require removal or opening of access panels or
doors. Stands, ladders, or platforms may be required to gain
proximity to the area being checked.''
(2) For the CDCCLs specified in paragraphs 2.C.(2)(c),
2.C.(2)(d), and 2.C.(15)(a) of the service bulletin, do the
applicable actions using a method approved in accordance with the
procedures specified in paragraph (k) of this AD. The applicable
service information listed in Table 1 of this AD is one approved
method.
