What happened
On 28 September 2002, an Aerotrike Scout, registration ZU-CLJ, was conducting a private VFR flight departing from Springs Airfield (FASI). The pilot and one passenger were returning to the microlight general flying area when the aircraft's engine suddenly failed.
Upon the loss of power, the pilot assessed the surrounding environment, noting that the terrain near the flight path was characterized by trees, a railway line, power lines, and uneven ground. Seeking the safest possible landing site, the pilot opted to maneuver over Murry Park dam. The aircraft subsequently performed an emergency landing in the water. While there were two injuries reported among the occupants, no fatalities occurred. The aircraft sustained extensive damage during the impact.
The investigation
SACAA AIID investigators reviewed the maintenance history and operational status of the aircraft. Records indicated that the Aerotrike Scout had been properly maintained, having completed only 22 flight hours since its last annual inspection, which was certified on 28 August 2002. The pilot held a valid microlight pilot license with the appropriate type endorsement and a current medical certificate. Following the accident, the engine underwent a ground run, which revealed no mechanical defects.
Findings
- The primary factor in the accident was an undetermined engine failure.
- The pilot's decision to target the dam was an attempt to avoid hazardous obstacles such as power lines, trees, and rough terrain.
- The aircraft was in a state of compliant maintenance at the time of the incident.
