Airworthiness Directives; Lockheed Martin Corporation/Lockheed 
Martin Aeronautics Company Airplanes

AGENCY: Federal Aviation Administration (FAA), DOT.

ACTION: Notice of proposed rulemaking (NPRM).

-----------------------------------------------------------------------

SUMMARY: We propose to supersede an existing airworthiness directive 
(AD) that applies to all Lockheed Martin Corporation/Lockheed Martin 
Aeronautics Company Model L-1011 series airplanes. The existing AD 
currently 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. Since we issued that AD, we have received 
reports of small cracks in additional areas outside those addressed in 
the existing AD, prior to the inspection threshold required by the 
existing AD. This proposed AD would reduce certain compliance times for 
the initial inspection, and the repetitive inspection interval for 
certain airplanes. We are proposing this AD to prevent corrosion or 
fatigue cracking of certain structural elements, which could result in 
reduced structural integrity of the airplane.

DATES: We must receive comments on this proposed AD by November 30, 
2012.

ADDRESSES: You may send comments, using the procedures found in 14 CFR 
11.43 and 11.45, by any of the following methods:

Discussion

    On July 8, 2005, we issued AD 2005-15-01, Amendment 39-14191 (70 FR 
42262, July 22, 2005), for all Lockheed Martin Corporation/Lockheed 
Martin Aeronautics Company Model L-1011 series airplanes. That AD 
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. That 
AD resulted from new recommendations related to incidents of fatigue 
cracking and corrosion in transport category airplanes that are 
approaching or have exceeded their economic design goal. We issued that 
AD to prevent corrosion or fatigue cracking of certain structural 
elements, which could result in reduced structural integrity of the 
airplane.

Actions Since Existing AD Was Issued

    Since we issued AD 2005-15-01, Amendment 39-14191 (70 FR 42262, 
July 22, 2005), we have received reports of small cracks found outside 
the areas addressed by the existing AD. Specifically, these cracks were 
found from inner wing station (IWS) 477.70 to IWS 372.64 (inboard) and 
from outer wing station (OWS) 52.2 to OWS 296.5 (outboard).

Relevant Service Information

    AD 2005-15-01, Amendment 39-14191 (70 FR 42262, July 22, 2005), 
refers to Lockheed Tristar L-1011 Service Bulletin 093-51-041, Revision 
1, dated March 3, 2000 (a ``collector service bulletin''), as the 
appropriate source of service information for the required actions. 
This service bulletin has since been revised. We have reviewed Lockheed 
Service Bulletin 093-51-041, Revision 2, dated March 30, 2010, which, 
in turn, refers to Lockheed Service Bulletin 093-57-195, now at 
Revision 4, dated March 17, 2010.
    Lockheed Service Bulletin 093-57-195, Revision 4, dated March 17, 
2010, includes the following changes:
     Supersedes Lockheed Service Bulletin 093-57-069, Revision 
4, dated October 5, 1998.
     Reduces the initial inspection threshold to 15,000 flight 
cycles; or 15,000 flight cycles after incorporation of Lockheed Service 
Bulletin 093-57-069, Revision 4, dated October 5, 1998.
     Reduces the repetitive inspection interval to 1,750 flight 
cycles for Model L-1011-385-3 airplanes.
     Changes the fastener hole cold working procedure from 
``FTI-LCC-8701'' to ``FTI-LASC-51-20-01.''

FAA's Determination

    We are proposing this AD because we evaluated all the relevant 
information and determined the unsafe condition described previously is 
likely to exist or develop in other products of these same type 
designs.

Proposed AD Requirements

    This proposed AD would retain all requirements of AD 2005-15-01, 
Amendment 39-14190 (70 FR 42262, July 22, 2005). This proposed AD would 
reduce the initial inspection threshold for certain airplanes for 
accomplishment of the actions specified in Lockheed Service Bulletin 
093-57-195, Revision 4, dated March 17, 2010, and would reduce the 
repetitive inspection interval for Model L-1011-385-3 airplanes. This 
proposed AD would also require accomplishing the actions specified in 
the service information described previously.

Changes to Existing AD

    This proposed AD would retain all requirements of AD 2005-15-01, 
Amendment 39-14191 (70 FR 42262, July 22, 2005). Since AD 2005-15-01 
was issued, the AD format has been revised, and certain paragraphs have 
been rearranged. As a result, the corresponding paragraph identifiers 
have changed in this proposed AD, as listed in the following table:

                      Revised Paragraph Identifiers
------------------------------------------------------------------------
   Requirement in AD 2005-15-01,
   Amendment 39[dash]14190 (70 FR     Corresponding requirement in this
       42262, July 22, 2005)                     proposed AD
------------------------------------------------------------------------
           paragraph (a)                       paragraph (g).
           paragraph (b)                       paragraph (h).
           paragraph (c)                       paragraph (i).
------------------------------------------------------------------------

    In addition, we have removed paragraph (b)(2) from AD 2005-15-01, 
Amendment 39-14190 (70 FR 42262, July 22, 2005), and added a new 
sentence to paragraph (h)(3) of this proposed AD to specify that 
information on additional methods of compliance can be obtained from 
the Manager, Atlanta Aircraft Certification Office (ACO). We might 
decide to approve certain sections of the Lockheed L-1011 structural 
repair manual as an alternative method of compliance with this proposed 
AD, as provided by paragraph (l) of this proposed AD.
    We have also revised the applicability of the existing AD 2005-15-
01, Amendment 39-14190 (70 FR 42262, July 22, 2005), to identify model 
designations as published in the most recent type certificate data 
sheet for the affected models.

Costs of Compliance

    We estimate that this proposed AD affects 26 airplanes of U.S. 
registry. We estimate the following costs to comply with this proposed 
AD:

    We have received no definitive data that would enable us to provide 
cost estimates for the retained on-condition actions specified in this 
proposed 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 proposed AD would not have federalism 
implications under Executive Order 13132. This proposed AD would 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 the proposed 
regulation:
    (1) Is not a ``significant regulatory action'' under Executive 
Order 12866,
    (2) Is not a ``significant rule'' under the 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.

The Proposed Amendment

    Accordingly, under the authority delegated to me by the 
Administrator, the FAA proposes to amend 14 CFR part 39 as follows:

PART 39--AIRWORTHINESS DIRECTIVES

    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]

    2. The FAA amends Sec.  39.13 by removing airworthiness directive 
(AD) 2005-15-01, Amendment 39-14190 (70 FR 42262, July 22, 2005), and 
adding the following new AD:

(e) Unsafe Condition

    This AD was prompted by reports of small cracks in additional 
areas outside those addressed in the existing AD (AD 2005-15-01, 
Amendment 39-14190 (70 FR 42262, July 22, 2005)), prior to the 
inspection threshold required by the existing AD. We are issuing 
this AD to prevent corrosion or fatigue cracking of certain 
structural elements, which could result in reduced structural 
integrity of the airplane.

(f) Compliance

    Comply with this AD within the compliance times specified, 
unless already done.

(g) Retained Inspections With Revised Service Information and Reduced 
Compliance Times

    This paragraph restates the inspection required by paragraph (a) 
of AD 2005-15-01, Amendment 39-14190 (70 FR 42262, July 22, 2005), 
with revised service information and reduced compliance times for 
paragraph (g)(16) of this AD. At the time specified in the ``Initial 
Compliance Time'' column of table 1 to paragraph (g) 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, or Revision 2, dated March 30, 2010. As of the 
effective date of this AD, only Lockheed Tristar L-1011 Service 
Bulletin 093-51-041, Revision 2, dated March 30, 2010, may be used 
for the actions required by this paragraph. Thereafter, repeat the 
inspections at intervals specified in the ``Repetitive Intervals'' 
column of table 1 to paragraph (g) of this AD.
