PRIOR TO DEPARTURE, THE ACFT WAS OBSERVED BEING RUN UP WITH THE ENG SPUTTERING & BACKFIRING QUITE BADLY. THE ACFT RETURNED TO THE HANGER & 3 LOWER PLUGS WERE CHANGED. THE FLT WAS THEN RESUMED. THE ACFT WAS NEXT OBSERVED OFF SHORE, WITH THE ENG SPUTTERING & MISSING, & THE BANNER HAVING BEEN RELEASED. THE ACFT THEN PITCHED UP, STALLED & STRUCK THE WATER. ENG EXAMINATION REVEALED NUMEROUS MECHANICAL DISCREPANCIES. THE #4 EXHAUST VALVE FAILED IN FATIGUE. THE RIGHT EXHAUST FLAME TUBE WAS DETERIORATED & SEPARATED WITH PARTS MISSING WHICH WERE LARGER THAN THE OPENING IN THE EXHAUST MANIFOLD. 4/5 OF THE #2 PISTON CAP SKIRT WAS MISSING. THE #2 SCRAPER RING ON THE #2 PISTON WAS BROKEN IN HALF. THE #4 EXHAUST CAM LOBE WAS WORN TO ABOUT 1/2 ITS NORMAL HEIGHT. THE #4 EXHAUST CAM FOLLOWER FACE WAS CONCAVED & PITTED. THE OIL PUMP HOUSING & GEARS SHOWED SCRATCH MARKS SUGGESTIVE OF METAL CONTANINATION.
