What happened
On 5 August 2003, a Gippsland GA200C, registered as ZS-OLF, departed from Ermelo Aerodrome for a local recreational flight. Shortly after takeoff, at approximately 0450Z, the aircraft struck a water pan located northwest of Amsterdam at coordinates S26º 25’ and E030º 28’. The impact resulted in two fatalities, as both the pilot and the passenger were killed in the crash. The aircraft was destroyed during the event.
The investigation
Investigators examined the engine, propeller, and airframe of the ZS-OLF. The inspection revealed no mechanical failures or evidence of unserviceability; all damage found was consistent with the impact of the accident. Maintenance records indicated that the aircraft had been kept in accordance with the approved maintenance schedule.
The pilot was found to be fully qualified, holding a valid commercial pilot license, a proper rating for the aircraft type, and a medical certificate that was valid at the time of the incident. Post-mortem examinations of the pilot showed no presence of alcohol or drugs in the system, and the injuries were consistent with an aviation accident.
Findings
At the time of the accident, the meteorological conditions in the Ermelo area were unstable, characterized by shifting low cloud and intermittent fog patches moving in from the southeast.
The investigation established that the pilot misjudged the aircraft's altitude while attempting a turn over the water, causing the wing to strike the surface. While the specific reason for the low flight altitude could not be determined, the presence of adverse weather and low visibility contributed to the circumstances of the crash.
