Aircraft involved
Probable cause & findings
INADEQUATE QUALITY CONTROL DURING MAINTENANCE OR MANUFACTURING BY FAILING TO USE CORROSION INHIBITER, WHICH RESULTED IN CORROSION, FATIGUE, AND SUBSEQUENT FAILURE.
Factual narrative
A PROPELLER BLADE FAILED DURING TAKEOFF AND ENTERED THE FUSELAGE. THE CREW ABORTED THE TAKEOFF SUCCESSFULLY. METALLURGICAL EXAMINATION REVEALED THAT THE BLADE FAILED AS A RESULT OF 'MULTIPLE FATIGUE CRACK ORIGINS (WHICH) HAD EMANATED FROM CORROSION PITS ON THE BLADE BORE SURFACE.' THE BLADE BORE WAS SUPPOSED TO BE COATED WITH A CHROMATE CONVERSION TO INHIBIT CORROSION. ENERGY DISPERSIVE X-RAY SPECTROGRAPH (EDS) REVEALED NO EVIDENCE THAT THE CHROMATE CONVERSION COATING HAD BEEN ACCOMPLISHED.
