Airworthiness Directives; Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Airplanes

FAA / Federal Register · 2019-16130

The FAA proposes to adopt a new airworthiness directive (AD) for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382, 382B, 382E, 382F, 382G, C-130A, C-130B, C-130BL, C130E, C- 130H, C 130H 30, C130J, C130J-30, EC130Q, HC130H, KC 130H, NC-130B, NC130, and WC-130H airplanes. This proposed AD was prompted by a report indicating that two elevator booster assemblies experienced significant hydraulic fluid leaks, caused by fatigue cracks in the actuator cylinder. This proposed AD would require an inspection to determine the part number of the elevator booster actuator, repetitive ultrasonic inspections of the actuator to detect cracking, and replacement of cracked elevator booster assemblies. The FAA is proposing this AD to address the unsafe condition on these products.
