Airworthiness Directive · Amendment 39-9617 · 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 inspections of the handrail assembly at the main entrance door to detect loose or missing rivets, abnormal movement between the handrail pivot-tube and the spigot that attaches to the bearing assembly, and cracks on the handrail pivot-tube. It also requires repair or replacement of the assembly, if necessary, and provides for two optional terminating actions. This amendment is prompted by a report indicating that fatigue cracks and loose rivets were found on the handrail assembly of the main passenger entrance door on an in-service airplane. The actions specified by this AD are intended to prevent these conditions, which can lead to the failure of the door handrail assembly; such failure could allow the door to fall free and subsequently cause injury to people on the airplane or on the ground.
