What happened
The aircraft attempted to depart from a gravel runway measuring approximately 1,600 feet in length. Environmental conditions during the operation included variable crosswinds, which can complicate ground handling and directional control. As the airplane accelerated down the runway for takeoff, the pilot monitored performance parameters closely.
Approximately halfway through the available runway distance, the pilot observed a significant anomaly: a decrease in indicated airspeed of 10 knots. This loss of speed during the critical takeoff roll prompted an immediate decision to abort the departure. The pilot applied maximum braking and reverse thrust (if applicable) to halt the aircraft's momentum.
Despite these efforts, the airplane was unable to come to a complete stop before reaching the end of the paved or gravel surface. The aircraft overran the runway boundary. Upon impact with the terrain beyond the runway limit, the nose landing gear structure failed catastrophically. The nose gear sheared off under the stress of the overrun, causing the forward fuselage to pitch downward and the airplane to nosed over.
The investigation
Examination of the wreckage confirmed that the nose landing gear had separated from the airframe. The failure mode was consistent with overload due to the ground impact associated with the runway overrun. No evidence of pre-impact mechanical failure of the gear system was found; the damage was a result of the accident sequence rather than its cause.
Findings
The primary factor in this incident was the inability to stop within the remaining runway distance after the decision to abort. Contributing factors included the short length of the gravel runway and the variable crosswind conditions which may have affected braking efficiency and directional control during the high-speed abort maneuver.
