## Abstract

This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 222, 222B, 222U, 230 and 430 helicopters that requires rewiring and testing the fuel valve switch on each engine and testing the ignitor system. This amendment is prompted by an in-flight incident in which a fuel valve switch failed, causing the fuel valve to inadvertently close. The actions specified by this AD are intended to prevent interruption of the fuel supply caused by failure of the fuel switch, which could result in loss of engine power and subsequent loss of control of the helicopter.
