What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
While passing K1A7 (en route to airventure, oshkosh, WI) pilot felt abnormal airframe vibrations and attempted an emergency landing on runway 180. During turn to align on the runway, pilot observed a portion of the propeller blade depart the aircraft and he reduced power due to increased severe vibration. Surface headwind contributed to airspeed loss and aircraft stall. Aircraft contacted the ground (on landing gear) short of the paved runway surface and stopped upon striking the airport perimeter fence. No aircraft fire occurred. Impact with the fence resulted in damage to the leading edge of the left wing and bending of the fuselage frame severe enough to not allow movement of the fuel cutoff control linkage. FAA iic found aircraft fuel level to be at least 3/4 full and engine oil full. No signs of ground scarring were observed. Damage to vertical fence and gate framing appeared consistent with the non-high speed impact described by the pilot. NTSB investigator and aircraft owner agreed a propeller damage analysis may be required. Aircraft owner stated that the aircraft maintenance records (requested by the FAA iic) would be provided upon his return to azalea aviation at cook county airport, adel, GA.
As the FAA filed it
WHILE PASSING K1A7 (EN ROUTE TO AIRVENTURE, OSHKOSH, WI) PILOT FELT ABNORMAL AIRFRAME VIBRATIONS AND ATTEMPTED AN EMERGENCY LANDING ON RUNWAY 180. DURING TURN TO ALIGN ON THE RUNWAY, PILOT OBSERVED A PORTION OF THE PROPELLER BLADE DEPART THE AIRCRAFT AND HE REDUCED POWER DUE TO INCREASED SEVERE VIBRATION. SURFACE HEADWIND CONTRIBUTED TO AIRSPEED LOSS AND AIRCRAFT STALL. AIRCRAFT CONTACTED THE GROUND (ON LANDING GEAR) SHORT OF THE PAVED RUNWAY SURFACE AND STOPPED UPON STRIKING THE AIRPORT PERIMETER FENCE. NO AIRCRAFT FIRE OCCURRED. IMPACT WITH THE FENCE RESULTED IN DAMAGE TO THE LEADING EDGE OF THE LEFT WING AND BENDING OF THE FUSELAGE FRAME SEVERE ENOUGH TO NOT ALLOW MOVEMENT OF THE FUEL CUTOFF CONTROL LINKAGE. FAA IIC FOUND AIRCRAFT FUEL LEVEL TO BE AT LEAST 3/4 FULL AND ENGINE OIL FULL. NO SIGNS OF GROUND SCARRING WERE OBSERVED. DAMAGE TO VERTICAL FENCE AND GATE FRAMING APPEARED CONSISTENT WITH THE NON-HIGH SPEED IMPACT DESCRIBED BY THE PILOT. NTSB INVESTIGATOR AND AIRCRAFT OWNER AGREED A PROPELLER DAMAGE ANALYSIS MAY BE REQUIRED. AIRCRAFT OWNER STATED THAT THE AIRCRAFT MAINTENANCE RECORDS (REQUESTED BY THE FAA IIC) WOULD BE PROVIDED UPON HIS RETURN TO AZALEA AVIATION AT COOK COUNTY AIRPORT, ADEL, GA.
