AD 99-10-04 Amendment 39-11158

This amendment adopts a new airworthiness directive (AD), applicable to all British Aerospace (Jetstream) Model 4101 airplanes, that requires modification of the pulley assemblies of the elevator and rudder control cables on the rear pressure bulkhead. 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 failure of the pulley assemblies of the elevator and rudder control cables in the event of an elevator or rudder control cable jam, which could result in reduced controllability of the airplane.
