After an airborne spray, the aircraft landed in the Fengshan operational area to pick up the mechanic and then headed back to Chishan Base. Flying northward along Kaoping Stream, the aircraft made a request to Pingtung Control Tower to pass through the glide path of Pingtung Airport, ascend to 200 feet over the high-voltage power cable tower, and then descend back to approximately 50 feet for a 5-minute flight just above the water. The mechanic stated that despite the rain, visibility was fair and he could see the buildings and trees along the stream. However, visibility through the front windshield was limited because of the rain.
The aircraft went down at approximately 1008 which is about 2 to 3 minutes after the aircraft reported to have passed the water reservoir near the sand-retaining dam on Kaoping Stream,. The helicopter crashed in an nearly horizontal attitude with a last recorded speed of 60Kts and altitude of roughly 50 feet.
The cockpit immediately filled with water after the aircraft went down. The aircraft rolled to the right and the left door bounced open. The mechanic abandoned the cockpit first, followed by the pilot. The pilot was not injured in the crash, however though the mechanic suffered a minor bruise to the right side of his forehead.
The pilot drowned when he tried to swim ashore and was pronounced dead on arrival to the hospital.
Probable causes
The aircraft flew in poor visibility, and failed to maintain safe altitude; there was a lack of situational awareness of ground (water) obstruction. The aircraft struck the water because it was flying at an altitude too low for the pilot to take corrective actions.
Contributing factors
1. Noncompliance with regulations to file a flight plans.
2. Failure to follow.visual flight rules.
3. Lack of training and ignorance of potential danger when conducting visual flights..
