## Analysis

THE EXPERIMENTAL AIRCRAFT EQUIPPED WITH A BUICK V-8 ALUMINUM BLOCK ENGINE EXPERIENCED POWER LOSS ON APPROACH FOR LANDING. THE PILOT DECIDED THAT THE DISTANCE AND TERRAIN WAS TOO GREAT FOR A GLIDE TO THE AIRPORT, AND AN EMERGENCY WATER LANDING IN A NEARBY LAKE WAS MADE. THE ENGINE WAS TESTED AND NO DISCREPANCIES WERE DISCOVERED.
