Airworthiness Directive · Amendment 39-8898 · Saab AB, Saab Aerosystems Airplanes
Saab AB, Saab Aerosystems Airplanes
This AD applies to Saab AB, Saab Aerosystems SAAB 340B, 340A (SAAB SF340A).
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain SAAB Model SAAB SF340A and SAAB 340B airplanes. This action requires installation of a placard in the cockpit that informs the flight crew of the prohibition against moving the power levers below "flight idle" (beta mode) when the airplane is airborne. This amendment is prompted by an incident during which a Model SAAB 340B airplane, that was in "beta mode" for a short duration during descent, lost all engine power. The action specified in this AD is intended to prevent engine overspeed and the resultant loss of engine power.
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.
