## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

DECLARED AN EMERGENCY DUE TO ENGINE FAILURE. UNABLE TO MAKE AIRPORT, CRASHED IN A FIELD. (.4)ATLANTIC SOUTHEAST AIRLINE FLIGHT 529 WAS CLIMBING THROUGH 18,000', WHEN A BLADE FROM THE LEFT PROPELLER SEPARATED. THIS RESULTED IN DISTORTION OF THE LEFT ENGINE NACELLE, EXCESSIVE DRAG, LOSS OF WING LIFT, & REDUCED DIRECTIONAL CONTROL. THE DEGRADED PERFORMANCE RESULTED IN A FORCED LANDING. WHILE LANDING, THE AIRPLANE PASSED THROUGH TREES, IMPACTED THE GROUND, & WAS FURTHER DAMAGED BY POSTIMPACT FIRE. AN EXAM OF THE LEFT PROPELLER REVEALED THE BLADE HAD FAILED DUE TO A FATIGUE CRACK THAT ORIGINATED FROM MULTIPLE CORROSION PITS IN THE TAPER BORE SURFACE OF THE BLADE SPAR. THE CRACK HAD PROPAGATED TOWARD THE OUTSIDE OF THE BLADE & AROUND BOTH SIDES OF THE TAPER BORE. DUE TO 2 PREVIOUS BLADE FAILURES (SEPARATIONS), A BORESCOPE INSPECTION PROCEDURE HAD BEEN DEVELOPED BY HAMILTON STANDARD TO INSPECT RETURNED BLADES (THAT HAD REJECTABLE ULTRASONIC INDICATIONS) FOR EVIDENCE OF CRACKS, PITS & CORROSION. THE ACCIDENT BLADE WAS ONE OF 490 REJECTED BLADES THAT HAD BEEN SENT TO HAMILTON STANDARD FOR FURTHER EVALUATION & POSSIBLE REPAIR. MAIN                                                             TENANCE TECHNICIANS, WHO INSPECTED THE BLADE, LACKED PROPER NDI FAMILIARIZATION TRAINING & SPECIFIC EQUIPMENT TO IDENTIFY THE CORROSION THAT RESULTED IN FATIGUE. (SEE NTSB/AAR-96/06 FOR ADDITIONAL INFORMATION).
