Docket No. 98-SW-61-AD
Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to Eurocopter France Model AS 332L2 helicopters with a certain power-loss printed circuit board (PCB) installed. This action requires replacing that power-loss PCB with an airworthy power-loss PCB. This amendment is prompted by malfunctions discovered during environmental testing of the power-loss PCB conducted by the manufacturer. The actions specified in this AD are intended to prevent incorrect engine status indications, random activation of the maximum rotor revolutions-per-minute (RPM) alarm, and failure to reset the One- Engine Inoperative (OEI) logic after an actual loss of power from one engine.
