The pilot on-board a Grumman G-164A aircraft with registration ZS-IRW took off from Middelburg Aerodrome (FAMB) on a crop spraying exercise over a farm in Doornkop area. Two full loads of chemicals were uplifted and sprayed over the farm without incident; thereafter, the aircraft returned to base to uplift the third load. After uplifting the third load, the aircraft took off to the Doornkop farm again. The first and second crop spraying patterns were uneventful, but during the initiation of a climb for the third spray pattern at about 50 feet above ground level (AGL), the engine lost power and stopped.
The pilot instantly dumped the remaining chemical load to lighten the aircraft’s weight and initiated a forced landing on an open field. The aircraft landed on a soft muddy terrain on an open field, and it flipped over. The aircraft was substantially damaged during the landing sequence; however, the pilot was not injured.

The investigation revealed that the engine stopped because of the failed impeller bearing and broken impeller gear which caused the supercharger to malfunction.
