## Discrepancy

DOWEL SHEARED IN FLIGHT, THE ACFT WAS A TOTAL LOSS, NO INJURIES TO CREW, BUT WAS CLASSIFIED AS AN INCIDENT.  NO PROP STRIKES EVER RECORDED, INCLUDING THE NEW DEFINITION.  THE INSURANCE COMPANY REQUESTED THE DOWEL FOR METALLURGY TESTS.  GIVEN THE TIMES BETWEEN THE O/H.  CALENDAR - ALMOST 11 YEARS AND FLIGHT 1881, DIFFICULT TO PROVIDE ANY PREVENTATIVE ACTION FOR THIS TYPE OF OCCURRENCE.  HAVE OWNED ACFT SINCE 1988.  ENGINE HAS BEEN O/H TWICE IN THIS TIME.  (K)
