Airworthiness Directive · Amendment 39-17534 · Standard practices/structures
Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Airplanes
This AD applies to all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L-1011-385-1, L-1011-385-1-14, L-1011-385-1-15, and L-1011-385-3 airplanes, certificated in any category.
We are superseding an airworthiness directive (AD) for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model L-1011 series airplanes. AD 2005-15-01 required 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 new AD reduces certain compliance times for the initial inspection and the repetitive inspection interval for certain airplanes. This AD was prompted by reports of small cracks in additional areas outside those addressed in AD 2005-15-01, prior to the inspection threshold required by the AD 2005-15-01. 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.
This paragraph restates the inspections 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 (The applicable service bulletins are also identified in Table 1 to paragraph (g) of this AD.) 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.
