Narrative:
The Piper 25-235 Pawnee aircraft took off on a private flight from runway 03 at Potchefstroom Aerodrome (FAPS), with the intention to land at Bospan airstrip.
The pilot stated that during the climb phase at approximately 300 feet (ft) above ground level (AGL), she noticed partial engine power loss which was below 2400 revolutions per minute (RPM). At this time, the aircraft had already flown beyond the runway and the pilot could not land back on the runway. The pilot then sought out and identified an open field covered with grass ahead of the aircraft’s path on which to conduct an emergency landing. After touchdown on the grass, the aircraft ran over a body of water which led to the main landing gear wheels sinking into the muddy soil; the aircraft nosed over and came to rest in an inverted position. The aircraft sustained substantial damage during the accident sequence. The pilot did not sustain injuries; he disembarked the aircraft without assistance.

Probable Cause
Water contaminated fuel led to partial engine power loss during the initial climb phase which led to the inability of the aircraft to climb. This prompted the pilot to perform a forced landing on an open area in a grass-covered wetland which led to substantial damage to the aircraft.

Contributory Factor
Draining fuel samples too soon after refuelling; not allowing time for any impurities/contaminants in the fuel to settle into the drain sump/point of each tank before draining fuel samples.
