A Grumman G-164 AgCat, RP-R1423, sustained substantial damage following a forced landing due to loss of engine power at Purok 5, Brgy. Concepcion, Maco, Davao de Oro.
The accident occurred after the second round of spraying activities at the banana plantation in the area was completed. The aircraft had earlier taken off from the MEPI airstrip located at Sto. Tomas, Davao del Norte.
According to the pilot, he observed the engine sputtered while executing a turn, just after completing his fourth (4th) line of spraying for his second (2nd) sortie. The engine continued to sputter and subsequently began to lose power. The pilot adjusted his throttle settings to regain power, however, the engine continued to sputter, and the aircraft began to lose altitude.
The pilot decided to look for a suitable area for a forced landing. He spotted a creek that appeared to be a potential landing spot, but decided not to proceed because he could not estimate the water’s depth. Instead, he opted to make the forced landing on a small clearing within the banana plantation area
Primary Cause Factors

Contributory Cause Factor
