## Analysis

WHILE TURNING TO BEGIN A SWATH RUN AT ABOUT 200 FT AGL, A PROPELLER BLADE FAILED AND SEPARATED. SUBSEQUENTLY, THE ENGINE BEGAN A SEVERE VIBRATION AND ALSO SEPARATED. OIL COVERED THE WINDSHIELD AND PREVENTED FORWARD VISIBILITY. THE PILOT REPORTED THAT HE WAS TOO BUSY TRYING TO PUT OUT A FIRE TO DUMP HIS LOAD. DURING THE FORCED LANDING, THE AIRCRAFT COLLIDED WITH TREES, THEN IMPACTED THE GROUND. A METALLURGICAL EXAMINATION OF THE MCCAULEY MODEL P2A36098-8/S90AT-4 PROPELLER, PN 122A34098-4, REVEALED THAT IT FAILED FROM FATIGUE. THE PROPELLER HAD ABOUT 411 HRS TOTAL FLIGHT TIME SINCE NEW.
