Airworthiness Directive · Amendment 39-11289 · McDonnell Douglas Model MD-90-30 Series Airplanes
McDonnell Douglas Model MD-90-30 Series Airplanes
Superseded. A later AD replaced this one: AD 2014-24-03. Comply with the one in force.
All Model MD-90-30 airplanes, certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to all McDonnell Douglas MD-90-30 series airplanes, that requires revising the Airworthiness Limitations Section of the Instructions for Continued Airworthiness [MD-90-30 Airworthiness Limitations Instructions (ALI)] to incorporate certain replacement times for safe-life limited parts. This amendment is prompted by analysis of data that identified reduced replacement times for certain safe-life limited parts. The actions specified by this AD are intended to prevent fatigue cracking of various safe-life limited parts; such fatigue cracking could adversely affect the structural integrity of these airplanes.
