            Background: This Directive was originally issued in September 1992 to address two reports of uncontained failure of AlliedSignal TFE731-3 first stage low pressure turbine discs following failure of certain low pressure turbine nozzle airseals. Following a report of a further low pressure turbine disc failure, this Directive has been amended to reflect more stringent requirements for verifying low pressure rotor lock-up during engine start and for the detection of rubbing noises following engine shut down.
