The FAA is superseding Airworthiness Directive (AD) 2019-18- 09, which applied to all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G airplanes; and Model C-130A, HP-C-130A, EC-130Q, C-130B, and C-130H airplanes. AD 2019-18-09 required a visual inspection of the center wing upper and lower rainbow fittings for cracks, an eddy current inspection of the center wing lower rainbow fittings for cracks, and replacement if necessary. This AD was prompted by an analysis of reported cracks showing repetitive inspections are needed to adequately address cracked inner tangs of the center wing lower rainbow fittings. This AD requires repetitive inspections of the center wing upper and lower rainbow fittings for cracks and replacement if necessary. The FAA is issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2019-18-09, with revised service information. Except as specified in paragraph (h) of this AD: Before the accumulation of 15,000 flight hours on the lower center wing rainbow fitting, or within 30 days after October 11, 2019 (the effective date of AD 2019-18-09), whichever occurs later, do the inspections required by paragraphs (g)(1) and (2) of this AD, in accordance with the Accomplishment Instructions of Lockheed Martin Aeronautics Company Alert Service Bulletin A382-57-98, Revision 1, dated August 16, 2019; or Lockheed Martin Aeronautics Company Alert Service Bulletin A382-57-98, Revision 2, dated February 14, 2023. If any cracks are found during any inspection required by paragraphs (g)(1) and (2) of this AD, replace the rainbow fitting before further flight.
(1) Do a visual inspection of the center wing upper and lower rainbow fittings for any cracks.
(2) Do an eddy current inspection of the center wing lower rainbow fittings for any cracks.
This paragraph restates the exception specified in paragraph (h) of AD 2019-18-09, with no changes. For any airplane on which the number of flight hours on the lower rainbow fitting cannot be determined for paragraph (g) of this AD: Do the inspections required by paragraphs (g)(1) and (2) of this AD within 30 days after October 11, 2019 (the effective date of AD 2019-18-09).
Except as specified in paragraph (j) of this AD: Within 5,000 flight hours after accomplishing the inspections required by paragraph (g) of this AD, or within 30 days after the effective date of this AD, whichever occurs later, do the inspections specified in paragraphs (i)(1) and (2) of this AD, in
accordance with the Accomplishment Instructions of Lockheed Martin Aeronautics Company Alert Service Bulletin A382-57-98, Revision 2, dated February 14, 2023. Repeat the inspections thereafter at intervals not to exceed 5,000 flight hours. If any crack is found during any inspection required by paragraph (i)(1) or (2) of this AD, replace the rainbow fitting before further flight.
(1) Do a visual inspection of the left and right center wing upper and lower rainbow fittings for any crack.
(2) Do an eddy current inspection of the left and right center wing lower rainbow fittings for any crack.
For any airplane on which the number of flight hours on the lower rainbow fitting cannot be determined for paragraph (i) of this AD: Do the inspections required by paragraphs (i)(1) and (2) of this AD within 30 days after the effective date of this AD.
Although Lockheed Martin Aeronautics Company Alert Service Bulletin A382-57-98, Revision 1, dated August 16, 2019; and Lockheed Martin Aeronautics Company Alert Service Bulletin A382-57-98, Revision 2, dated February 14, 2023; specify to report inspection findings, this AD does not require any report.
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.
