McDonnell Douglas DC-9-10 to DC-9-50 Airplanes: Revised Airworthiness Directive to Detect Engine Pylon Fatigue Cracking

The Federal Aviation Administration (FAA) has revised an earlier proposed airworthiness directive for certain McDonnell Douglas Model DC-9-10 to DC-9-50 series airplanes, as well as C-9 military aircraft, to detect and correct fatigue cracking in the engine pylon aft upper spar cap. The revised directive aims to prevent major damage to the adjacent structure and reduce the airplane's structural integrity.
