## Abstract

This amendment supersedes an existing airworthiness directive (AD), applicable to Bell Helicopter Textron, a Division of Textron Canada (BHT), Model 206B and 206L helicopters, that currently requires a revision to the Limitations section of the FAA-approved Supplemental Type Certificate (STC) Rotorcraft Flight Manual Supplement (RFMS) until replacement of the engine power-out warning sensor on BHT Model 206B and 206L helicopters equipped with Allison 250-C20R engines in accordance with certain supplemental type certificates. This amendment requires a revision to the Limitations section of the STC RFMS, but removes the requirement for replacement of the engine power-out warning sensor. This amendment is prompted by a reevaluation of the need for an engine power-out warning sensor based on the lack of reported operational occurrences of the false engine-out warnings. The actions specified by this AD are intended to maintain a heightened pilot awareness that false engine-out warnings may occur when practicing autorotations and could result in an unnecessary emergency autorotative landing.
