Airworthiness Directive · Amendment 39-9137 · Jetstream Aircraft Limited (formerly British Aerospace, Regional Airlines Limited) HP137 Mk1, Jetstream Series 200, and Jetstream Models 3101 and 3201 Airplanes
Jetstream Aircraft Limited (formerly British Aerospace, Regional Airlines Limited) HP137 Mk1, Jetstream Series 200, and Jetstream Models 3101 and 3201 Airplanes
HP137 Mk1, Jetstream Series 200, and Jetstream Models 3101 and 3201 airplanes (all serial numbers), certificated in any category.
This amendment adopts a new airworthiness directive (AD) that applies to Jetstream Aircraft Limited (JAL) HP137 Mk1, Jetstream series 200, and Jetstream Models 3101 and 3201 airplanes. This action requires repetitively inspecting the left and right pilot windscreens for poly vinyl butyrate (PVB) interlayer cracks, and replacing any windscreen that has a crack exceeding certain limits. Several reports of PVB interlayer cracking of pilot windscreens on the affected airplanes prompted this action. The actions specified by this AD are intended to prevent such windscreen cracking, which, if not detected and corrected, could result in decompression injuries.
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.
