Airworthiness Directives; Jetstream Aircraft Limited (Formerly British Aerospace, Regional Airlines Limited) HP137 Mk1 and Jetstream Series 200 Airplanes

This amendment supersedes AD 81-09-03 R1, which currently requires repetitively inspecting the rudder pedal adjusting mounting bracket for cracks on Jetstream Aircraft Limited (JAL) HP137 Mk1 and Jetstream Series 200 airplanes, and replacing any cracked bracket. The Federal Aviation Administration's policy on aging commuter-class aircraft is to eliminate, or in certain instances, reduce the number of repetitions of certain short-interval inspections when improved parts or modifications are available. This action requires replacing the mounting bracket with a new mounting bracket of improved design as terminating action for the repetitive inspections that are currently required by AD 81-09-03 R1. The actions specified by this AD are intended to prevent inadvertent rudder movement caused by a cracked rudder pedal adjusting bracket, which, if not detected and corrected, could result in loss of rudder control.
