The helicopter disintegrated and burned to the ground.
The pilot, the only occupant of the aircraft, died in the crash.
Causes of the Accident
1 Primary Cause
Hit the ground due to poor operating technique - due to a tight turn with the Bambi Bucket system, loaded with water, causing the bucket to oscillate and subsequent loss of control of the helicopter
2 Contributing Causes
1. Pilot with reduced flight experience in forest fire fighting missions
2. Pilot with reduced flight experience with suspended load
3. Pilot with no experience in mountain flight;
4. Helicopter mass at operating limits;
5. Downward currents caused by wind circulation over the mountain (mountain effect);
6. Omission in the execution of emergency procedures;
7. Deficient organization of the operator for not having identified the need for mountain flight education and training;
8. Deficient organization of the Operations Manual by not contemplating a flight prevention and safety program that identifies and corrects human failures;
9. Deficient information in the mass and balance spreadsheet.
