The FAA is adopting a new airworthiness directive (AD) for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382, 382B, 382E, 382F, 382G, and 382J airplanes; and Model C-130A, HP- C-130A, EC-130Q, 282-44A-05 (C-130B), C-130B, and C-130H airplanes. This AD was prompted by a report indicating a quality audit found aft fuselage sloping longerons manufactured with an overaged condition. This AD requires a conductivity check on certain aft fuselage sloping longerons and applicable on-condition actions. This AD also limits the installation of certain aft fuselage sloping longerons under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
For all airplanes except Model 382J airplanes: Within 35 days after the effective date of this AD, review the airplane maintenance records to determine if the left or right aft fuselage sloping longeron, having part number (P/N) 342986-(), has been replaced on or after December 31, 2012.
If, during the airplane maintenance records review required by paragraph (g) of this AD, it is determined that the left or right aft fuselage sloping longeron, having P/N 342986-(), has been replaced on or after December 31, 2012, or it cannot be conclusively determined that the part has not been replaced, before further flight, do a conductivity check on the longeron, in accordance with paragraph 2.E. of the Accomplishment Instructions of Lockheed Martin Aeronautics Company Alert Service Bulletin A382-53-69, dated April 12, 2023.
If, during the conductivity check required by paragraph (h) of this AD, the conductivity measurements exceed the values specified in paragraph 2.E.(6) or (7), as applicable, of the Accomplishment Instructions of Lockheed Martin Aeronautics Company Alert Service Bulletin A382-53-69, dated April 12, 2023, before further flight, do a Rockwell hardness test of the longeron, in accordance with paragraph 2.F. of the Accomplishment Instructions of Lockheed Martin Aeronautics Company Alert Service Bulletin A382-53-69, dated April 12, 2023.
For all Model 382J airplanes: Within 35 days after the effective date of this AD, do a conductivity check on any aft fuselage sloping longeron having P/N 342986-13/-14/-19/-20, in accordance with paragraph 2.D. of the Accomplishment Instructions of Lockheed Martin Aeronautics Company Alert Service Bulletin A382J-53-004, dated March 27, 2023.
If, during the conductivity check required by paragraph (j) of this AD, the conductivity measurements exceed the values specified in paragraph 2.E.(6) or (7), as applicable, before further flight, do a Rockwell hardness test of the longeron, in accordance with paragraph 2.E. of the Accomplishment Instructions of Lockheed Martin Aeronautics Company Alert Service Bulletin A382J-53-004, dated March 27, 2023.
If, during any hardness test required by paragraph (i) or (k) of this AD, the hardness reading is below 80 Rockwell B, before further flight, repair using a method approved by the Manager, East Certification Branch, FAA.
Although Lockheed Martin Aeronautics Company Alert Service Bulletin A382-53-69, dated April 12, 2023; and Lockheed Martin Aeronautics Company Alert Service Bulletin A382J-53-004, dated March 27, 2023; specify to submit all conductivity and hardness inspection results to Lockheed Martin Aeronautics Company, this AD does not require any report.
(1) For all airplanes except Model 382J airplanes: As of the effective date of this AD, no person may install any aft fuselage sloping longeron having P/N 342986-() unless the conductivity check specified in paragraph (h) of this AD has been accomplished and all applicable actions specified in paragraphs (i) and (l) have been accomplished.
(2) For all Model 382J airplanes: As of the effective date of this AD, no person may install any aft fuselage sloping longeron having P/N 342986-() unless the conductivity check specified in paragraph (j) of this AD has been accomplished and all applicable actions specified in paragraphs (k) and (l) have been accomplished.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
