Airworthiness Directive · Amendment 39-11275 · Short Brothers Model SD3-30 Series Airplanes
Short Brothers Model SD3-30 Series Airplanes
Model SD3-30 series airplanes that have been modified in accordance with Shorts Service Bulletin SD330-30-30, dated June 1988; certificated in any category.
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.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
