            This Airworthiness Directive becomes effective on 2 October 2002.

            Background: This Directive has been issued to require core samples of crankshaft material be taken from certain crankshafts for the purpose of metallurgical evaluation. The requirement follows reports of crankshaft failures in service. The failed crankshafts had been manufactured from steel suspected of containing material anomalies.
