Airworthiness Directive · Amendment 39-9308 · BAE Systems (Operations) Limited Airplanes
BAE Systems (Operations) Limited Airplanes
This AD applies to BAE Systems (Operations) Limited BAe 146-100A, BAe 146-200A, BAe 146-300A.
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 British Aerospace Model BAe 146-100A, -200A, and -300A airplanes, that requires modification of the elevator control system of the flight controls. This amendment is prompted by reports of low frequency constant amplitude oscillations of the elevator control system and non-centering of the pitch control upon autopilot disconnect. The actions specified by this AD are intended to prevent uncommanded descent upon autopilot disconnect and reduced controllability of the airplane due to low frequency constant amplitude oscillations.
