## Analysis

THE ACFT LANDED WHEELS-UP WITH ONE ENGINE FEATHERED AND NOSED OVER DURING THE SLIDE-OUT. THE PILOT HAD INTENTIONALLY FEATHERED THE LEFT ENGINE TO 'TRY OUT' THE ACFT. THE LEFT ENGINE HAS THE ONLY ENGINE DRIVEN HYDRAULIC PUMP. THIS PUMP ISNECESSARY TO LOWER LANDING GEAR AND FLAPS. THERE WAS NOT TIME TO LOWER THE GEAR BY EMERGENCY MEANS SO THE ACFT WAS LANDED GEAR AND FLAPS UP. DURING THE LANDING THE ACFT NOSED OVER AND WAS DESTROYED. THERE WAS NO FIRE AND ALL OCCUPANTS WERE ABLE TO EXIT THE WRECKAGE UNINJURED. THE LANDING WAS MADE IN A FIELD OFF THE AIRPORT.
