The FAA is adopting a new airworthiness directive (AD) for 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, and C-130B airplanes. This AD requires 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 reports of cracked inner tangs of the center wing lower rainbow fittings. The FAA is issuing this AD to address the unsafe condition on these products.
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 the effective date of this AD, 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. 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.
For any airplane on which the number of flight hours on the lower rainbow fitting cannot be determined, do the inspections required by paragraphs (g)(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, specifies 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.
