On July 28, 2006, a Cessna 140 (registration N89669) was involved in an aviation accident near Cunningham, KS. Investigators recorded the probable cause as: The pilot's decision to abort the takeoff roll due to insufficient airspeed, which resulted in the aircraft drifting off the runway and nosing over. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive.
A pilot aborted a takeoff roll after feeling insufficient airspeed for rotation. The aircraft drifted right into runway mud and nosed over, sustaining substantial damage with no mechanical anomalies found.
What happened
The pilot initiated the takeoff roll but determined during the acceleration phase that the aircraft was not achieving the necessary airspeed for rotation. Consequently, the decision was made to abort the takeoff. As the aircraft decelerated along the runway, it drifted toward the right side. The right main landing gear encountered soft mud located on the shoulder of the runway, causing the nose to pitch forward and resulting in a nosedown attitude.
The investigation
Following the incident, a thorough examination of the airplane's systems was conducted to determine if any mechanical failures contributed to the event. The inspection revealed no anomalies or malfunctions within the aircraft's systems that would have prevented normal operation or influenced the outcome.
Probable cause
The pilot's decision to abort the takeoff roll due to insufficient airspeed, which resulted in the aircraft drifting off the runway and nosing over.
