Aircraft involved
Probable cause & findings
THE PILOT'S POOR DECISION AND MISJUDGEMENT OF DISTANCE. THE SEPARATION OF THE CYLINDER, FAILURE OF THE PROPELLER TO FEATHER, AND IMPACT WITH WIRES AND A RESIDENCE WERE FACTORS IN THE ACCIDENT.
Factual narrative
THE PLT CONTACTED THE ARSA CONTROLLER FOR ADVISORIES AFTER LOSING PWR ON THE RIGHT ENG OVER AN AIR FORCE BASE. THE CONTROLLER ADVISED THE PLT THAT HIS POSITION WAS NEAR A CIVILIAN ARPT WITH LIMITED MAINTENANCE FACILITIES AND AN AIR FORCE BASE. THE PLT ADVISED THAT HE DESIRED TO CONTINUE TO A LARGER CIVILIAN ARPT ALONG HIS ROUTE WHERE HE COULD OBTAIN SERVICE. THE PLT THEN INFORMED THE CONTROLLER THAT HE COULD BARLEY SEE THE GROUND AND THAT HE WAS UNABLE TO MAINTAIN ALT DUE TO THE PROPELLER NOT FEATHERING. THE ACFT OVERFLEW A SMALL CIVILIAN ARPT AND THE PLT TOLD THE UNICOM OPERATOR THAT HE WOULD ATTEMPT TO LAND ON AN INTERSTATE HWY. THE ACFT OVERFLEW THE HWY AND IMPACTED AN ELECTRICAL TRANSMISSION LINE AND COLLIDED WITH A RESIDENCE. POST ACCIDENT INSPECTION REVEALED THE RIGHT ENG #3 CYLINDER HEAD FRACTURED ALLOWING THE HEAD TO DISPLACE OUTWARD 3/8 INCH. FRACTURE RESULTED FROM FATIGUE AT THREADED AREA BTW HEAD AND CYLINDER. THE PROPELLER GOVERNOR OPERATED NORMALLY DURING FUNCTIONAL TESTING AFTER THE ACCIDENT. Source: NTSB Aviation Accident Database (Pre-2008 Archive) Retrieved: 2026-02-12
