Airworthiness Directive · Amendment 39-9190 · BAE Systems (Operations) Limited Airplanes
BAE Systems (Operations) Limited Airplanes
This AD applies to BAE Systems (Operations) Limited Jetstream Model 4101.
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 Jetstream Model 4101 airplanes, that requires modification of the spoiler system. This amendment is prompted by reports of fatigue failures of the tee fittings of the spoiler bleed nipples. The actions specified by this AD are intended to ensure that the tee fittings do not fail, and subsequently lead to loss of the main system hydraulics.
