On October 4, 2007, a Cessna 172N (registration N2263E) was involved in an aviation accident near Calhan, CO. Investigators recorded the probable cause as: The student pilot's failure to maintain directional control during the soft field takeoff, which resulted in the aircraft veering off the runway and impacting a fence. This summary draws on records from the U.S. National Transportation Safety Board (NTSB) historical archive; 1 related events involving the same aircraft type or operator are linked below.
A student pilot lost control during a soft field takeoff, causing the aircraft to leave the runway, strike a fence, and nose over. No mechanical issues were found.
What happened
The incident occurred during the initial phase of flight when a student pilot was attempting a soft field takeoff. According to the pilot's account, the airplane began to veer to the left while still on the runway surface. The aircraft continued its lateral deviation until it departed the paved area and collided with a fence located adjacent to the runway. The force of this impact caused the nose gear to collapse, resulting in the airplane nosing over onto its fuselage.
The investigation
Following the accident, investigators conducted a thorough examination of the aircraft's systems to determine if any mechanical failures contributed to the loss of control. The pilot had reported no prior mechanical anomalies with the airplane before the event. Post-accident inspection confirmed that there were no mechanical discrepancies or system failures present in the aircraft that would have caused the veering behavior.
Findings
The primary factor in this accident was the aircraft leaving the runway environment during takeoff. The substantial damage to the airframe was a direct result of the ground impact with the fence and the subsequent nose-over. Since mechanical causes were ruled out, the event is attributed to pilot technique or control input errors during the critical takeoff roll phase.
Probable cause
The student pilot's failure to maintain directional control during the soft field takeoff, which resulted in the aircraft veering off the runway and impacting a fence.
