Airworthiness Directive · Amendment 39-9626 · British Aerospace Regional Aircraft Airplanes
British Aerospace Regional Aircraft Airplanes
This AD applies to British Aerospace Regional Aircraft Jetstream 3201, Jetstream Series 3101.
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) that applies to Jetstream Aircraft Limited (JAL) Jetstream Models 3101 and 3201 airplanes. This action requires modifying the automatic airframe de-ice system to allow the wing and tail de-ice boots to automatically operate through one cycle. The present system repeats the wing de-ice boot inflation cycle before starting to inflate the tail de-ice boots. Reports of ice accumulating on the tail faster than the automatic tail de-ice boots inflate on the affected airplanes prompted this action. The actions specified by this AD are intended to prevent excessive ice accretion on the tail or wings of the affected airplanes, which could result in loss of control of the airplane.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
