Full official abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Short Brothers Model SD3-30 series airplanes, that requires modification of electrical wiring associated with heater components. 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 autofeather system, which could result in reduced controllability of the airplane in the event of engine failure during takeoff.
