AD 95-02-19 60 FR 6397

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.
