Factual narrative

THE PILOT REPORTED THAT DURING TAKEOFF, HE EXPERIENCED A 400 RPM DROP IN THE ENGINE SPEED. HE BEGAN A RIGHT TURN TO LAND ON RUNWAY 04, BUT REPORTEDLY, THE ENGINE THEN STOPPED. THE PILOT INTENDED TO LAND ON THE HULL WITH THE GEAR RETRACTED; HOWEVER, THE PLANE "PANCAKED" ONTO A SMALL RIDGELINE AND WAS BADLY DAMAGED. AN INVESTIGATION REVEALED THAT THE CARBURETOR HEAT CONTROL LEVER WAS IN THE "OFF" (COLD) POSITION, BUT THE CARBURETOR HEAT CONTROL DOOR WAS IN THE HOT POSITION. THE CONTROL CABLE HAD SLIPPED OUT OF POSITION AT THE CLAMP WHICH SECURED IT TO THE ENGINE PYLON. THE ENGINE DRIVEN FUEL PUMP WAS FOUND FRACTURED, BUT NO FUEL STAINS WERE FOUND IN THE AREA OF THE PUMP. LATER, THE ENGINE WAS PREPARED FOR A RUN-UP, AND SUBSEQUENTLY, IT OPERATED NORMALLY. THE DENSITY ALTITUDE WAS ABOUT 9700 FT. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
