The helicopter had taken off from a temporary landing site in the vicinity of Pego in order to apply phytosanitary products by spraying chemicals on the surface of a crop field using auxiliary fumigation equipment installed on the aircraft.
After flying for about 1:30 hours, and during the sixth takeoff of the day, after landing to refill the chemicals, during the initial takeoff phase and before reaching an effective translational lift speed, the aircraft lost height, with the right part of the spray boom impacting the crop field. This caused the subsequent dynamic rollover and impact with the ground.
The aircraft sustained significant damage to its landing gear, booms, spray equipment and main rotor. The pilot, who exited the aircraft under his own power, was not injured.
The investigation has determined that the accident was most likely caused by the execution of a takeoff maneuver without maintaining suitable external visual references.
The following factors contributed to the accident:
• Applying less power than necessary to avoid losing altitude before reaching the effective translational lift speed during takeoff.
• Maintaining a curved, instead of straight, flight path over the terrain during takeoff.
• The improper implementation of the reduced flight periods specified in the operator’s Operations Manual for pilots with little experience in aerial spraying operations
