Airworthiness Directives; AlliedSignal Inc. TFE731-40R-200G Turbofan Engines

This amendment adopts a new airworthiness directive (AD) that is applicable to AlliedSignal Inc. TFE731-40R-200G turbofan engines. This action requires inspection of the fuel flow meter tube assembly part number (P/N) 3061157-2, which connects the fuel control to the fuel flow meter, and eventual replacement of the tube and fuel flow meter mounting bracket. This amendment is prompted by two in-flight shutdowns on two recently certified TFE731-40R turbofan engines within the last six months that resulted from fuel flow meter tube assembly failures. The actions specified in this AD are intended to prevent fuel from spraying on and around electrical components due to a cracked fuel line, which can result in an in-flight engine shutdown, and could possibly result in an engine fire.
