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

2. Section 39.13 is amended by adding the following new airworthiness 
directive:

2005-15-01 Lockheed: Amendment 39-14190. Docket 99-NM-129-AD.

    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-
041, Revision 1, dated March 3, 2000. Thereafter, repeat the 
inspections at intervals specified in the ``Repetitive Intervals'' 
column of Table 1 of this AD.
