Airworthiness Directive · Amendment 39-9045 · 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 installation of a placard near the decouple control handle for the elevator control system to ensure that the pilots are made aware that maintenance action is required to reset the disconnect unit once the decouple control handle has been pulled. This amendment is prompted by a report that, if the decouple control handle for the elevator control system is pulled, the lock linkage will remain unlocked until it is reset during maintenance. The actions specified by this AD are intended to prevent reduced controllability of the airplane due to loss of the mechanical linkage between the pilots' elevator controls, and each pilot having control authority over only one-half of the elevator control system.
