The Grumman G-164A Ag-Cat sustained substantial damage due to loss of engine power while on an aerial spraying operation at Purok Avocado, Brgy. Pangi, Maco, Davao de Oro. The pilot who was the sole occupant did not sustain any injury.
The pilot was on pull-up maneuver to gain altitude after the third (3rd) pass of chemical spray of his fifth load, when the engine suddenly sputtered followed by loss of engine power.
Immediately, the pilot checked and saw that the engine oil pressure instrument is slowly decreasing. He then dumped the remaining chemicals to gain altitude and tried to restart the engine. After the engine failed to re-start, the pilot decided to make a forced landing on the banana plantation. The aircraft landed and came to a stop with the nose in a downward position with last heading of 330 degrees.
The pilot egressed safely after performing engine shutdown.
