Airworthiness Directives; Dornier Model 328-100 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all Dornier Model 328-100 series airplanes, that requires repetitive lubrication of the engine control push-pull cables, and installation of heating tubes on the control cables in the cockpit area and in the left-hand and right-hand engine balconies, which terminates the repetitive lubrication requirement. 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 ice from building up on the engine control push- pull cables, which could result in friction or jamming of the engine controls, and consequent reduced controllability of the airplane.
