On August 11, 1996, an Aeronca 7CCM (registration N2836E) was involved in an aviation accident near Marsing, ID. Investigators recorded the probable cause as: loss of engine power for undetermined reason(s), and failure of the pilot to maintain adequate airspeed, while maneuvering for a forced landing, which resulted in a stall and collision with terrain. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A single-engine aircraft experienced engine failure while surveying fields at low altitude. The pilot attempted a 180-degree turn toward an open field, but the engine briefly restarted then quit again. The aircraft rocked its wings, then nosed down and impacted the ground in a steep descent. Investigators found no reason for the engine power loss.
Incident Details
The flight departed from a private crop duster airstrip with the purpose of surveying fields scheduled for spraying later that night and the following day. Approximately five minutes after takeoff, a witness observed the aircraft cruising at a low altitude, roughly level with nearby power poles.
Witness Account
The witness reported hearing the engine cease operation. Subsequently, the aircraft began a 180-degree turn, apparently aiming for an open field. During this turn, the engine restarted briefly before quitting again. The witness then saw the aircraft's wings begin to rock, followed by a sudden drop of the nose. The aircraft descended steeply and impacted the ground.
Investigation
Investigators examined the wreckage and operational history but could not determine a cause for the reported loss of engine power. No pre-existing mechanical issues or other factors were identified that would explain the engine's intermittent operation and eventual failure.
