Probable cause
The crankshaft gear attach bolt loosening and backing out of its crankshaft bore, which led to the fatigue failure of the crankshaft gear dowel pin due to excessive working of the gear. The sequence of failures was the result of the engine overhaul shop's failure to comply with an Airworthiness Directive and the engine manufacturer's Service Bulletin.
