DEPARTMENT OF TRANSPORTATION
Federal Aviation Administration
14 CFR Part 39
[Docket No. 99-NM-129-AD; Amendment 39-14190; AD 2005-15-01]
RIN 2120-AA64
Airworthiness Directives; Lockheed Model L-1011-385 Series
Airplanes
AGENCY: Federal Aviation Administration (FAA), Department of
Transportation (DOT).
ACTION: Final rule.
-----------------------------------------------------------------------
SUMMARY: This amendment adopts a new airworthiness directive (AD),
applicable to all Lockheed Model L-1011-385 series airplanes, that
requires repetitive inspections to detect corrosion or fatigue cracking
of certain structural elements of the airplane; corrective actions if
necessary; and incorporation of certain structural modifications. This
action is necessary to prevent corrosion or fatigue cracking of certain
structural elements, which could result in reduced structural integrity
of the airplane. This action is intended to address the identified
unsafe condition.
DATES: Effective August 26, 2005.
The incorporation by reference of certain publications listed in
the regulations is approved by the Director of the Federal Register as
of August 26, 2005.
ADDRESSES: The service information referenced in this AD may be
obtained from Lockheed Martin Aircraft & Logistics Centers, 120 Orion
Street, Greenville, South Carolina 29605. This information may be
examined at the Federal Aviation Administration (FAA), Transport
Airplane Directorate, Rules Docket, 1601 Lind Avenue, SW., Renton,
Washington; or at the FAA, Atlanta Aircraft Certification Office, One
Crown Center, 1895 Phoenix Boulevard, suite 450, Atlanta, Georgia.

SUPPLEMENTARY INFORMATION: A proposal to amend part 39 of the Federal
Aviation Regulations (14 CFR part 39) to include an airworthiness
directive (AD) that is applicable to all Lockheed Model L-1011-385
series airplanes was published as a supplemental notice of proposed
rulemaking (NPRM) in the Federal Register on December 16, 2004 (69 FR
75282). That action proposed to require repetitive inspections to
detect corrosion or fatigue cracking of certain structural elements of
the airplane; corrective actions if necessary; and incorporation of
certain structural modifications.
Comments
Interested persons have been afforded an opportunity to participate
in the making of this amendment. Due consideration has been given to
the comments received.
Request To Separate Service Bulletins into Two Tables
One commenter requests that Table 1--Compliance Times be split into
two tables--an inspection table (Table I) and an inspection/
modification table (Table II)--similar to that in Lockheed Tristar L-
1011 Service Bulletin 093-51-041, Revision 1, dated March 3, 2000
(referenced in the supplemental NPRM as an appropriate source of
service information; hereafter called the ``Collector Service
Bulletin''). The commenter believes that Table 1 of the supplemental
NPRM implies that all listed service bulletins have a terminating
modification, which would cause confusion. Whereas Table I lists
service bulletins with no terminating action in most cases, and Table
II lists service bulletins with terminating actions.
We partially agree. We do not agree that Table 1 of the AD should
be split into two tables. As explained in the preamble of the
supplemental NPRM, we revised the original NPRM by adding Table 1 for
the sole purpose of listing the compliance times for each individual
service bulletin listed in Tables I and II of the referenced Lockheed
service bulletin. We made this change based on commenters' requests to
clarify the compliance times. We agree with the commenter that
operators could misinterpret that all service bulletins listed in Table
1 have a terminating modification. Therefore, we have revised Table 1
of the AD by adding a new column ``Terminating Action'' to identify
service bulletins that have a terminating modification.
Request To Include Revision Level of Service Bulletin
One commenter notes that the service bulletin date (i.e., 093-53-
054, dated August 12, 1975) identified in paragraph (a)(8) of the
supplemental NPRM corresponds to Revision 1 of the service bulletin,
not the original issue as indicated.
From this comment, we infer that the commenter is requesting
clarification. The commenter is correct that the service bulletin
reference should have included ``Revision 1.'' We have revised
paragraph (a)(8) of the final rule accordingly.
Conclusion
After careful review of the available data, including the comments
noted above, the FAA has determined that air safety and the public
interest require the adoption of the rule with the change previously
described. The FAA has determined that this change will neither
increase the economic burden on any operator nor increase the scope of
the AD.
Changes to 14 CFR Part 39/Effect on the AD
On July 10, 2002, the FAA issued a new version of 14 CFR part 39
(67 FR 47997, July 22, 2002), which governs the FAA's airworthiness
directives system. The regulation now includes material that relates to
altered products, special flight permits, and alternative methods of
compliance. However, for clarity and consistency in this final rule, we
have retained the language of the supplemental NPRM regarding that
material.
Cost Impact
There are approximately 125 airplanes of the affected design in the
worldwide fleet. The FAA estimates that 49 airplanes (7 in-service and
42 in storage) of U.S. registry will be affected by this AD. Few, if
any of the 42 airplanes in storage, will be returned to service due to
the economic feasbility of operating and maintaining older technology
airplanes. Therefore, the cost estimate below is based on the 7 in-
service airplanes.
It will take approximately 32 work hours per airplane (for actions
specified in Table I of the Collector Service Bulletin) and 97 work
hours per airplane (for actions specified in Table II of the Collector
Service Bulletin) to accomplish the required inspections, at an average
labor rate of $65 per work hour. Based on these figures, the cost
impact of the AD on U.S. operators is estimated to be $14,560, or
$2,080 per airplane, per inspection cycle (for Table I), and $44,135,
or $6,305 per airplane, per inspection cycle (for Table II).
It will take approximately 614 work hours per airplane to
accomplish the required modifications, at an average labor rate is $65
per work hour. Required parts will cost approximately $142,275 per
airplane. Based on these figures, the cost impact of the proposed
[[Page 42263]]
AD on U.S. operators is estimated to be $1,275,295, or $182,185 per
airplane.
The cost impact figures discussed above are based on assumptions
that no operator has yet accomplished any of the requirements of this
AD action, and that no operator would accomplish those actions in the
future if this AD were not adopted. The cost impact figures discussed
in AD rulemaking actions represent only the time necessary to perform
the specific actions actually required by the AD. These figures
typically do not include incidental costs, such as the time required to
gain access and close up, planning time, or time necessitated by other
administrative actions.
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 Impact
The regulations adopted herein 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. Therefore, it
is determined that this final rule does not have federalism
implications under Executive Order 13132.
For the reasons discussed above, I certify that this action (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. A final evaluation has been prepared for this action
and it is contained in the Rules Docket. A copy of it may be obtained
from the Rules Docket at the location provided under the caption

Applicability: All Model L-1011-385 series airplanes,
certificated in any category.
Note 1: This AD applies to each airplane identified in the
preceding applicability provision, regardless of whether it has been
modified, altered, or repaired in the area subject to the
requirements of this AD. For airplanes that have been modified,
altered, or repaired so that the performance of the requirements of
this AD is affected, the owner/operator must request approval for an
alternative method of compliance in accordance with paragraph (d) of
this AD. The request should include an assessment of the effect of
the modification, alteration, or repair on the unsafe condition
addressed by this AD; and, if the unsafe condition has not been
eliminated, the request should include specific proposed actions to
address it.
Compliance: Required as indicated, unless accomplished
previously.
To prevent corrosion or fatigue cracking of certain structural
elements, which could result in reduced structural integrity of the
airplane, accomplish the following:
Inspections
(a) At the time specified in the ``Initial Compliance Time''
column of Table 1 of this AD, perform structural inspections to
detect corrosion or fatigue cracking of certain structural elements
of the airplane, in accordance with the applicable service bulletins
listed under ``Service Bulletin Number, Revision, and Date'' in
Tables I and II of Lockheed Tristar L-1011 Service Bulletin 093-51-
