On March 26, 1991, a Piper PA-25 (registration N9845P) operated by Double "s" Flying, Inc. was involved in an aviation accident near Spiro, OK. Investigators recorded the probable cause as: The pilot's inability to maintain control of the airplane during the forced landing due to a total loss of engine power for undetermined reasons. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
The pilot lost engine power shortly after takeoff and executed a forced landing on an upslope. The aircraft slid into fencing, nosed over, and was destroyed by fire.
What happened
Shortly after departing the airport, the pilot experienced a complete loss of engine power for reasons that were not immediately determined. With no option to return to the departure field or reach another suitable airfield, the pilot initiated a forced landing in the surrounding terrain.
The aircraft made initial ground contact on a gentle upslope while maintaining a wings-level attitude with the nose slightly pitched down. However, approximately 20 feet after this initial touchdown, the airplane slid forward into two fence posts and associated wire fencing material. This impact caused the aircraft to nosed over violently.
Following the rollover, a post-impact fire ignited and rapidly consumed the wreckage, resulting in total destruction of the aircraft.
Probable cause
The pilot's inability to maintain control of the airplane during the forced landing due to a total loss of engine power for undetermined reasons.
