McDonnell Douglas Model DC-9, DC-9-80, and C-9 (Military) Series Airplanes, Model MD-88 Airplanes, and Model MD-90 Airplanes
Superseded. A later AD replaced this one: AD 2002-04-01. Comply with the one in force.
Model DC-9, DC-9-80, and C-9 (military) series airplanes, Model MD-88 airplanes, and Model MD-90 airplanes; as listed in McDonnell Douglas Alert Service Bulletins DC9-32A298 [for Model DC-9, DC-9-80, and C-9 (military) series airplanes, and Model MD-88 airplanes], and McDonnell Douglas Alert Service Bulletin MD90- 32A019 [for Model MD-90 airplanes], both dated December 19, 1996; certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain McDonnell Douglas Model DC-9, DC-9-80, and C-9 (military) series airplanes, Model MD-88 airplanes, and Model MD-90 airplanes. This action requires a visual check to determine the part and serial numbers of the upper lock link assembly of the nose landing gear (NLG); repetitive inspections of certain upper lock link assemblies to detect fatigue cracking; and modification of the NLG. This action also provides for terminating action for the repetitive inspections. This amendment is prompted by a report indicating that, due to fatigue cracking, the upper lock link assembly on an airplane fractured, and consequently prevented the NLG from extending fully. The actions specified in this AD are intended to prevent this assembly from fracturing due to fatigue cracking, and the NLG consequently failing to extend fully; this condition could result in injury to passengers and flight crew, and damage to the airplane.
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.
