Airworthiness Directive · Amendment 39-9409 · 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 supersedes an existing airworthiness directive (AD), applicable to certain Jetstream Model ATP airplanes, that currently requires daily and/or pre-flight cleaning and inspections to detect damaged main landing gear (MLG) wheel bearings and replacement of discrepant parts. That AD was prompted by reports of failure of the MLG wheel bearings. This action requires an additional inspection, in lieu of the pre-flight inspection, for certain airplanes. This action also requires the accomplishment of a terminating modification that eliminates the need for daily and pre-flight inspections. The actions specified by this AD are intended to prevent failure of the MLG wheel bearing, which could result in detachment of a MLG wheel from the airplane.
