Airworthiness Directive · Amendment 39-9246 · McDonnell Douglas Corporation Airplanes
McDonnell Douglas Corporation Airplanes
Superseded. A later AD replaced this one: AD 96-01-02. Comply with the one in force.
This AD applies to McDonnell Douglas Corporation MD-11 Series (all).
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model MD-11 series airplanes. This action requires a visual inspection to detect cracks or discrepancies in the aft mount beam assembly of the engines; and replacement of the cracked or discrepant aft mount beam assembly with a new assembly, or a previously inspected and re-identified assembly. This amendment is prompted by reports of cracking in a certain aft mount beam assembly on Airbus Model A310 series airplanes. The actions specified in this AD are intended to prevent cracks in the aft mount beam assembly of the engines, which could result in loss of the capability of the aft mount beam assembly to support engine loads, and possible separation of the engine from the airplane.
