What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(.4)The pilot stated he experienced a partial loss of engine power at 4,500 feet. He made a forced landing to an ultralight airfield. The airplane touched down long, went off the end of the runway, and nosed over. The engine was removed and transported to the engine manufacturer. The engine was placed in an engine test cell, started and developed power. (-23) the pilot reported a loss of power while enroute from dothan, AL to bessemmer, AL at 4500' MSL in VMC. Pilot stated that the engine was producing large vibrations and he performed an emergency landing under partial power at the happy valley community airpark (ultralight) 11 NM NE of the Troy, AL airport (toi). The aircraft's landing roll exceeded the runway length and struck tree stumps and dirt piles at a low rate of speed. The aircraft flipped on its back and came to rest at the end of the runway, left side of centerline. The aircraft sustained damage to both wing tips, the fuselage, vertical stabilizer, and nose landing gear. Subsequent investigation revealed that the engine was in good working order and that the propeller's #2 phenolic block had failed. This failure disconnected the propeller blade from the hub, thus causing severe vibration and loss of thrust.
As the FAA filed it
(.4)THE PILOT STATED HE EXPERIENCED A PARTIAL LOSS OF ENGINE POWER AT 4,500 FEET. HE MADE A FORCED LANDING TO AN ULTRALIGHT AIRFIELD. THE AIRPLANE TOUCHED DOWN LONG, WENT OFF THE END OF THE RUNWAY, AND NOSED OVER. THE ENGINE WAS REMOVED AND TRANSPORTED TO THE ENGINE MANUFACTURER. THE ENGINE WAS PLACED IN AN ENGINE TEST CELL, STARTED AND DEVELOPED POWER. (-23) THE PILOT REPORTED A LOSS OF POWER WHILE ENROUTE FROM DOTHAN, AL TO BESSEMMER, AL AT 4500' MSL IN VMC. PILOT STATED THAT THE ENGINE WAS PRODUCING LARGE VIBRATIONS AND HE PERFORMED AN EMERGENCY LANDING UNDER PARTIAL POWER AT THE HAPPY VALLEY COMMUNITY AIRPARK (ULTRALIGHT) 11 NM NE OF THE TROY, AL AIRPORT (TOI). THE AIRCRAFT'S LANDING ROLL EXCEEDED THE RUNWAY LENGTH AND STRUCK TREE STUMPS AND DIRT PILES AT A LOW RATE OF SPEED. THE AIRCRAFT FLIPPED ON ITS BACK AND CAME TO REST AT THE END OF THE RUNWAY, LEFT SIDE OF CENTERLINE. THE AIRCRAFT SUSTAINED DAMAGE TO BOTH WING TIPS, THE FUSELAGE, VERTICAL STABILIZER, AND NOSE LANDING GEAR. SUBSEQUENT INVESTIGATION REVEALED THAT THE ENGINE WAS IN GOOD WORKING ORDER AND THAT THE PROPELLER'S #2 PHENOLIC BLOCK HAD FAILED. THIS FAILURE DISCONNECTED THE PROPELLER BLADE FROM THE HUB, THUS CAUSING SEVERE VIBRATION AND LOSS OF THRUST.
