Summary
This document proposes to adopt a new airworthiness directive (AD) that would apply to certain Fairchild Aircraft, Inc. (Fairchild Aircraft) SA26, SA226, and SA227 series airplanes. The proposed AD would require you to modify the negative torque sensing test system to allow the igniters to automatically turn when an engine senses low torque. The proposed AD is the result of two instances of a dual engine flameout on the affected airplanes. The actions specified by the proposed AD are intended to prevent a dual engine flameout on the affected airplanes by providing a system that automatically turns on the engine igniters when low torque is sensed.A dual engine flameout could result in failure of both engines with consequent loss of control of the airplane.
