What happened
The airplane impacted terrain while attempting to depart from a 1,400-foot-long grass runway. The accident occurred as the aircraft approached the end of the strip, where it came over the edge of a significant drop-off. During the takeoff roll, the pilot reported that the airplane did not accelerate as expected. In an effort to gain necessary airspeed, the pilot lowered the nose of the aircraft further than usual. Despite these efforts, the aircraft failed to become airborne and struck the ground beyond the runway threshold.
The investigation
Following the incident, the pilot provided a statement regarding the events leading up to the impact. The pilot explicitly stated that there were no mechanical problems with the airplane prior to or during the takeoff roll. This indicates that the failure to accelerate was likely due to performance limitations related to the runway length and terrain rather than an equipment malfunction.
Findings
The primary factor in this accident was the insufficient runway length available for a safe takeoff given the aircraft's performance characteristics. The pilot's decision to continue the takeoff roll on a short grass strip, combined with the abrupt termination of the runway at a drop-off, resulted in a fatal outcome. The lack of mechanical issues confirms that the event was driven by operational constraints and terrain hazards.
Safety message
Pilots must carefully calculate takeoff performance requirements against available runway length, especially on unimproved surfaces like grass strips. Short runways with abrupt ends or terrain changes pose significant risks if the aircraft cannot achieve sufficient speed within the available distance.
