[Docket No. FAA-2012-1078; Directorate Identifier 2011-NM-012-AD] RIN 2120-AA64

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: Federal eRulemaking Portal: Go to http://www.regulations.gov.

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:

Estimated Costs ---------------------------------------------------------------------------------------------------------------- Cost on U.S. Action Labor cost Parts cost Cost per product operators ---------------------------------------------------------------------------------------------------------------- Inspections [retained actions 129 work-hours x $0 $10,965 per $285,090 per from existing AD 2005-15-01, $85 per hour = inspection cycle. inspection cycle. Amendment 39-14191 (70 FR 42262, $10,965 per July 22, 2005)]. inspection cycle. Modification [retained action 614 work-hours x $142,275 $194,465........... $5,056,194. from existing AD 2005-15-01, $85 per hour = Amendment 39-14191 (70 FR 42262, $52,190. July 22, 2005)]. ----------------------------------------------------------------------------------------------------------------

[[Page 63277]]

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
