THE PILOT OF THE ACCIDENT HELICOPTER WAS PERFORMING TEST FLIGHTS USING VARIOUS FLIGHT ATTITUDES TO CHANGE AIRFLOW PATTERNS THROUGH THE ENGINE COMPARTMENT WHEN THE ENGINE LOST POWER. THE PILOT STATED HE WAS TOO FAST AND TOO LOW TO COMPLETE A SMOOTH LANDING. DURING TOUCHDOWN THE HELICOPTER LANDED HARD AND SUSTAINED SUBSTANTIAL DAMAGE. POST ACCIDENT INSPECTION OF THE ENGINE REVEALED THE BORE DIAMETER ON THE CONNECTING ROD WAS INCORRECT WHERE IT ATTACHES TO THE CRANKSHAFT.
