Airworthiness Directive · Amendment 39-8870 · BAE Systems (Operations) Limited Airplanes
BAE Systems (Operations) Limited Airplanes
This AD applies to BAE Systems (Operations) Limited ATP.
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 Jetstream Model ATP series airplanes, that requires inspections to detect fatigue-related cracking and loose rivets in the subframe yoke assemblies of the quick engine change units (QECU) on both wings; replacement of rivets; and repair or replacement of yoke assemblies, if necessary. This amendment is prompted by in-service and fatigue test reports of cracking in the yoke of a QECU subframe. The actions specified by this AD are intended to prevent loss of structural integrity of the engine mount.
