Session #1 was in the afternoon after daybreak at 05:00 UTC and conducted 28 cycles. The session #1 was carried out with normal and safely. One Pilot was on-board in the aircraft. The session #2, the aircraft was take-off at 05:00 using runway 18. After take-off, the pilot turned to the left to the fertilization area. The fertilization area was on the left of the runway. The pilot informed while the aircraft turned to the left, he felt the strong wind from the right. Then the aircraft was descending and the left wing hit the palm tree. After losing the wing tip, the aircraft difficult to control and crashed into the palm trees on the left runway for about 238 meters from the end of runway 18. The aircraft was substantial damaged.
