What happened
On 12 January 2019, a Cessna Textron, C182N was conducting a private, hire-and-fly cross-country flight from Grand Central Aerodrome to Iwamanzi Game Lodge. While on final approach to Runway 33 at the destination, the aircraft experienced a sudden loss of engine power. The pilot attempted to restore power by advancing the throttle, but the engine remained unresponsive and eventually ceased operation.
As the aircraft lost altitude, the pilot identified telephone lines positioned near the runway threshold. To avoid the hazard of the wires, the pilot executed a forced landing in a field located approximately 300 metres short of the runway threshold. The impact resulted in substantial damage to the aircraft's nose gear, propeller, engine cowling, and lower fuselage. The two occupants on board sustained no injuries.
The investigation
SACAA AIID investigators examined the aircraft's mechanical state and the circumstances surrounding the power loss. Post-incident inspections and bench tests conducted by an aircraft maintenance organisation revealed that the engine started normally and operated within standard parameters during testing. Further technical examinations included:
- A visual and bench test of the carburettor, which showed no blockages.
- Verification of the fuel selector valve, which functioned correctly in all positions.
- An analysis of the fuel, which showed no evidence of water contamination.
- An inspection of the fuel line screens and strainers, which were found to be clear of obstructions.
Additionally, the investigation confirmed the aircraft had sufficient fuel for the planned flight duration and that all maintenance records, including the most recent mandatory periodic inspection, were up to date.
Findings
- The engine failure occurred during the final approach phase of the flight.
- The cause of the engine failure could not be determined following mechanical testing.
- The pilot's decision to land short of the runway was driven by the presence of telephone lines near the threshold.
- Meteorological conditions were visual (VMC) with a light risk of carburettor icing noted at the nearest weather station.
