Airworthiness Directive · Amendment 39-9756 · McDonnell Douglas Corporation Airplanes
McDonnell Douglas Corporation Airplanes
Superseded. A later AD replaced this one: AD 2001-09-18. Comply with the one in force.
This AD applies to McDonnell Douglas Corporation DC-9-81, DC-9-82, DC-9-83, DC-9-87, MD-88.
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), applicable to certain McDonnell Douglas Model DC-9-80 series airplanes and Model MD-88 airplanes, that requires a one-time inspection to detect cracking of the main landing gear (MLG) pistons, and repair or replacement of the pistons with new or serviceable parts, if necessary. This amendment is prompted by reports of failure of the MLG pistons that occurred during towing of the airplanes. The actions specified by this AD are intended to prevent fatigue cracking of the MLG pistons, which could result in failure of the pistons and subsequent damage to the airplane structure or injury to airplane occupants.
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.
