Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
AGENCY:
SUMMARY: The FAA is superseding an
existing airworthiness directive (AD),
which applies to certain McDonnell
Douglas transport category airplanes.
That AD currently requires, among other
things, revision of an existing program
of structural inspections. This new AD
requires implementation of a program of
structural inspections of baseline
structure to detect and correct fatigue
cracking in order to ensure the
continued airworthiness of these
airplanes as they approach the
manufacturer’s original fatigue design
life goal. This AD results from a
significant number of these airplanes
approaching or exceeding the design
service goal on which the initial type
certification approval was predicated.
We are issuing this AD to detect and
correct fatigue cracking that could
compromise the structural integrity of
these airplanes.
DATES: This AD becomes effective
November 29, 2006.
The Director of the Federal Register
approved the incorporation by reference
of certain publications listed in the AD
as of November 29, 2006.
The incorporation of a certain other
publication, as listed in the regulations,
was approved previously by the Director

Discussion
The FAA issued a notice of
supplemental notice of proposed
rulemaking (NPRM) to amend 14 CFR
part 39 to include an AD that
supersedes AD 96–13–03, amendment
39–9671 (61 FR 31009, June 19, 1996).
The existing AD applies to all
McDonnell Douglas Model DC–9–10,
–20, –30, –40, –50, and C–9 (military)
series airplanes. (Since the issuance of
that AD, the FAA has revised the
applicability of the existing AD to
identify model designations as
published in the most recent type
certificate data sheet for the affected
models.) That supplemental NPRM was
published in the Federal Register on
March 7, 2006 (71 FR 11328). That
supplemental NPRM proposed to
require implementation of a program of
structural inspections of baseline
structure to detect and correct fatigue
cracking in order to ensure the
continued airworthiness of these
airplanes as they approach the
manufacturer’s original fatigue design
life goal.

Comments
We provided the public the
opportunity to participate in the
development of this AD. No comments
have been received on the supplemental
NPRM or on the determination of the
cost to the public.
Conclusion
We have carefully reviewed the
available data and determined that air
safety and the public interest require
adopting the AD as proposed.
mstockstill on PROD1PC61 with RULES
Costs of Compliance
There are about 710 McDonnell
Douglas transport category airplanes
worldwide of the affected design. This
AD will affect about 477 airplanes of
U.S. registry, or 26 U.S. airline
operators.
The recurring inspection costs, as
required by AD 96–13–03, take 362
work hours per airplane, at an average
labor rate of $65 per work hour. Based
on these figures, the estimated cost of
the currently required actions is
$11,223,810, or $23,530 per airplane,
per inspection cycle.
The incorporation of the revised
procedures in this AD action will
require approximately 20 additional
work hours per operator to accomplish,
at an average labor rate of $65 per work
hour. Based on these figures, the cost to
the 26 affected U.S. operators to
incorporate these revised procedures
into the SID program is estimated to be
$33,800, or $1,300 per operator.
Additionally, the number of required
work hours for each inspection (and the
Supplemental Inspection Document
(SID) program), as indicated above, is
presented as if the accomplishment of
those actions were to be conducted as
‘‘stand alone’’ actions. However, in
actual practice, these actions for the
most part will be accomplished
coincidently or in combination with
normally scheduled airplane
inspections and other maintenance
program tasks. Further, any costs
associated with special airplane
scheduling are expected to be minimal.
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
VerDate Aug<31>2005
15:06 Oct 24, 2006
Jkt 211001
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); 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.
We prepared a regulatory evaluation
of the estimated costs to comply with
this AD and placed it in the AD docket.
See the ADDRESSES section for a location
to examine the regulatory evaluation.

Inspection for Transferred Airplanes
(m) Before any airplane that has exceeded
the fatigue life threshold (Nth) can be added
to an air carrier’s operations specifications, a
program for the accomplishment of the
inspections required by this AD must be
established per paragraph (m)(1) or (m)(2) of
this AD, as applicable.
(1) For airplanes that have been inspected
in accordance with this AD, the inspection of
each PSE must be accomplished by the new
operator in accordance with the previous
operator’s schedule and inspection method,
or the new operator’s schedule and
inspection method, at whichever time would
result in the earlier accomplishment date for
that PSE inspection. The compliance time for
accomplishment of this inspection must be
measured from the last inspection
accomplished by the previous operator. After
each inspection has been performed once,
each subsequent inspection must be
performed in accordance with the new
operator’s schedule and inspection method.
(2) For airplanes that have not been
inspected in accordance with this AD, the
inspection of each PSE required by this AD
must be accomplished either prior to adding
the airplane to the air carrier’s operations
specification, or in accordance with a
schedule and an inspection method approved
by the Manager, Los Angeles ACO. After each
inspection has been performed once, each
subsequent inspection must be performed per
the new operator’s schedule.
Inspections Accomplished Before the
Effective Date of This AD

AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: The FAA is superseding an existing airworthiness directive
(AD), which applies to certain McDonnell Douglas transport category
airplanes. That AD currently requires, among other things, revision of
an existing program of structural inspections. This new AD requires
implementation of a program of structural inspections of baseline
structure to detect and correct fatigue cracking in order to ensure the
continued airworthiness of these airplanes as they approach the
manufacturer's original fatigue design life goal. This AD results from
a significant number of these airplanes approaching or exceeding the
design service goal on which the initial type certification approval
was predicated. We are issuing this AD to detect and correct fatigue
cracking that could compromise the structural integrity of these
airplanes.
DATES: This AD becomes effective November 29, 2006.
The Director of the Federal Register approved the incorporation by
reference of certain publications listed in the AD as of November 29,
2006.
The incorporation of a certain other publication, as listed in the
regulations, was approved previously by the Director of the Federal
Register as of July 24, 1996 (61 FR 31009, June 19, 1996).
ADDRESSES: You may examine the AD docket on the Internet at https://

SUPPLEMENTARY INFORMATION:
Examining the Docket
You may examine the airworthiness directive (AD) docket on the
Internet at https://dms.dot.gov or in person at the Docket Management
Facility office between 9 a.m. and 5 p.m., Monday through Friday,
except Federal holidays. The Docket Management Facility office
(telephone (800) 647-5227) is located on the plaza level of the Nassif
Building at the street address stated in the ADDRESSES section.
Discussion
The FAA issued a notice of supplemental notice of proposed
rulemaking (NPRM) to amend 14 CFR part 39 to include an AD that
supersedes AD 96-13-03, amendment 39-9671 (61 FR 31009, June 19, 1996).
The existing AD applies to all McDonnell Douglas Model DC-9-10, -20, -
30, -40, -50, and C-9 (military) series airplanes. (Since the issuance
of that AD, the FAA has revised the applicability of the existing AD to
identify model designations as published in the most recent type
certificate data sheet for the affected models.) That supplemental NPRM
was published in the Federal Register on March 7, 2006 (71 FR 11328).
That supplemental NPRM proposed to require implementation of a program
of structural inspections of baseline structure to detect and correct
fatigue cracking in order to ensure the continued airworthiness of
these airplanes as they approach the manufacturer's original fatigue
design life goal.
[[Page 62381]]
Comments
We provided the public the opportunity to participate in the
development of this AD. No comments have been received on the
supplemental NPRM or on the determination of the cost to the public.
Conclusion
We have carefully reviewed the available data and determined that
air safety and the public interest require adopting the AD as proposed.
Costs of Compliance
There are about 710 McDonnell Douglas transport category airplanes
worldwide of the affected design. This AD will affect about 477
airplanes of U.S. registry, or 26 U.S. airline operators.
The recurring inspection costs, as required by AD 96-13-03, take
362 work hours per airplane, at an average labor rate of $65 per work
hour. Based on these figures, the estimated cost of the currently
required actions is $11,223,810, or $23,530 per airplane, per
inspection cycle.
The incorporation of the revised procedures in this AD action will
require approximately 20 additional work hours per operator to
accomplish, at an average labor rate of $65 per work hour. Based on
these figures, the cost to the 26 affected U.S. operators to
incorporate these revised procedures into the SID program is estimated
to be $33,800, or $1,300 per operator.
Additionally, the number of required work hours for each inspection
(and the Supplemental Inspection Document (SID) program), as indicated
above, is presented as if the accomplishment of those actions were to
be conducted as ``stand alone'' actions. However, in actual practice,
these actions for the most part will be accomplished coincidently or in
combination with normally scheduled airplane inspections and other
maintenance program tasks. Further, any costs associated with special
airplane scheduling are expected to be minimal.
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); 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.
We prepared a regulatory evaluation of the estimated costs to
comply with this AD and placed it in the AD docket. See the ADDRESSES
section for a location to examine the regulatory evaluation.

Discrepant Findings
(j) If any discrepancy (e.g., a PSE cannot be inspected as
specified in Volume II of the SID or does not match rework, repair,
or modification description in Volume I of the SID) is detected
during any inspection required by paragraph (i) of this AD,
accomplish the action specified in paragraph (j)(1) or (j)(2) of
this AD, as applicable.
(1) If a discrepancy is detected during any inspection performed
prior to \3/4\Nth or Nth: The area of the PSE
affected by the discrepancy must be inspected prior to
Nth or within 18 months of the discovery of the
discrepancy, whichever is later, in accordance with a method
approved by the Manager, Los Angeles ACO, FAA.
(2) If a discrepancy is detected during any inspection performed
after Nth: The area of the PSE affected by the
discrepancy must be inspected prior to the accumulation of an
additional [Delta]NDI/2, measured from the last non-discrepant
inspection finding, or within 18 months of the discovery of the
[[Page 62383]]
discrepancy, whichever occurs later, in accordance with a method
approved by the Manager of the Los Angeles ACO.
Reporting Requirements
(k) All negative, positive, or discrepant (discrepant finding
examples are described in paragraph (j) of this AD) findings of the
inspections accomplished under paragraph (i) of this AD must be
reported to Boeing, at the times specified in, and in accordance
with the instructions contained in, Section 4 of Volume I, Revision
6, of the SID. Information collection requirements contained in this
regulation have been approved by the Office of Management and Budget
(OMB) under the provisions of the Paperwork Reduction Act (44 U.S.C.
3501 et seq.) and have been assigned OMB Control Number 2120-0056.
Corrective Actions
(l) Any cracked structure of a PSE detected during any
inspection required by paragraph (i) of this AD must be repaired
before further flight in accordance with a method approved by the
Manager, Los Angles ACO, or by using a method approved in accordance
with procedures specified in paragraph (p) of this AD. Accomplish
follow-on actions described in paragraphs (l)(1), (l)(2), and (l)(3)
of this AD, at the times specified.
(1) Within 18 months after repair, perform a damage tolerance
assessment (DTA) that defines the threshold for inspection of the
repair and submit the assessment for approval.
(2) Before reaching 75% of the repair threshold as determined in
paragraph (l)(1) of this AD, submit the inspection methods and
repetitive inspection intervals for the repair for approval.
(3) Before the repair threshold, as determined in paragraph
(l)(1) of this AD, incorporate the inspection method and repetitive
inspection intervals into the FAA-approved structural maintenance or
inspection program for the airplane.
Note 6: For the purposes of this AD, we anticipate that
submissions of the DTA of the repair, if acceptable, should be
approved within six months after submission.
Note 7: Advisory Circular AC 25.1529-1, ``Instructions for
Continued Airworthiness of Structural Repairs on Transport
Airplanes,'' dated August 1, 1991, is considered to be additional
guidance concerning the approval of repairs to PSEs.
Inspection for Transferred Airplanes
(m) Before any airplane that has exceeded the fatigue life
threshold (Nth) can be added to an air carrier's
operations specifications, a program for the accomplishment of the
inspections required by this AD must be established per paragraph
(m)(1) or (m)(2) of this AD, as applicable.
(1) For airplanes that have been inspected in accordance with
this AD, the inspection of each PSE must be accomplished by the new
operator in accordance with the previous operator's schedule and
inspection method, or the new operator's schedule and inspection
method, at whichever time would result in the earlier accomplishment
date for that PSE inspection. The compliance time for accomplishment
of this inspection must be measured from the last inspection
accomplished by the previous operator. After each inspection has
been performed once, each subsequent inspection must be performed in
accordance with the new operator's schedule and inspection method.
(2) For airplanes that have not been inspected in accordance
with this AD, the inspection of each PSE required by this AD must be
accomplished either prior to adding the airplane to the air
carrier's operations specification, or in accordance with a schedule
and an inspection method approved by the Manager, Los Angeles ACO.
After each inspection has been performed once, each subsequent
inspection must be performed per the new operator's schedule.
Inspections Accomplished Before the Effective Date of This AD
(n) Inspections accomplished prior to the effective date of this
AD in accordance with Boeing Report No. L26-008, ``DC-9 All Series
Supplemental Inspection Document (SID),'' Volume I, Revision 6,
dated November 2002, are acceptable for compliance with the
requirements of paragraph (i) of this AD.
Acceptable for Compliance
(o) Boeing Report MDC 91K0263, ``DC-9/MD-80 Aging Aircraft
Repair Assessment Program Document,'' Revision 1, dated October
2000, provides inspection/replacement programs for certain repairs
to the fuselage pressure shell. These repairs and inspection/
replacement programs are considered acceptable for compliance with
the requirements of paragraphs (i), (l), and (m) of this AD for
repairs subject to that document.
Alternative Methods of Compliance (AMOCs)
(p)(1) The Manager, Los Angles ACO, has the authority to approve
AMOCs for this AD, if requested in accordance with the procedures
found in 14 CFR 39.19.
(2) Before using any AMOC approved in accordance with CFR 39.19
on any airplane to which the AMOC applies, notify the appropriate
principal inspector in the FAA Flight Standards Certificate Holding
District Office.
(3) An AMOC that provides an acceptable level of safety may be
used for any repair required by this AD, if it is approved by an
Authorized Representative for the Boeing Commercial Airplanes
Delegation Option Authorization Organization who has been authorized
by the Manager, Los Angeles ACO, to make those findings. For a
repair method to be approved, the repair must meet the certification
basis of the airplane and 14 CFR 25.571, Amendment 45, and the
approval must specifically refer to this AD.
(4) AMOCs approved previously for alternative inspection
procedures per AD 87-14-07 R1, amendment 39-6019; AD 94-03-01,
amendment 39-8807; and AD 96-13-03; are acceptable for compliance
with the actions required by paragraph (f) of this AD for
inspections performed before the requirements of paragraph (i) are
accomplished.
(5) AMOCs approved previously for repairs per AD 87-14-07 R1, AD
94-03-01, and AD 96-13-03; are acceptable for compliance with the
requirements of paragraph (l) of this AD.
