Airworthiness Directives; British Aerospace (Jetstream) Model 4101 Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain British Aerospace (Jetstream) Model 4101 airplanes, that requires a one-time inspection of the bottom aft roller of the main baggage-bay door structure for cracking or damage to the sub-frame; repetitive operational tests to determine if the counter- balance motor functions properly; and corrective actions, if necessary. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent sub-frame damage, which, if left undetected, could cause rapid decompression of the airplane and consequent injury to passengers and crew.
