Accident investigation report completed and information captured
Narrative: A Guimbal Cabri G2 helicopter used for training crashed near the Heliport EFAI in Contagem. Shortly after takeoff, control of the aircraft was lost, leading it to collide with a truck parked nearby. The aircraft sustained substantial damage. The pilots suffered serious injuries.
Contributing factors. - Attitude – undetermined. The IN may have felt a greater level of confidence flying with an AL so experienced in fixed-wing aviation, which could have contributed to complacency and overconfidence in the AL’s ability. This allowed the takeoff roll to develop differently than expected. - Training – a contributor. The AL did neither receive specific instructions relative to the presence of the obstacle (high-voltage power lines) nor the procedures to follow when operating in proximity to it. This is an indication of inefficiencies in the structured training process designed to enhance knowledge, skills, and decision-making. Additionally, the pre-flight briefing was not conducted properly, representing a missed opportunity to address this critical factor. - Handling of aircraft flight controls – a contributor. The helicopter's flight controls were not applied correctly during takeoff, preventing the aircraft from reaching the necessary altitude to clear the high-voltage power line. Additionally, when the collective was increased to clear the obstacle, the right pedal was not applied with sufficient amplitude, allowing the helicopter to enter a left yaw and subsequently lose control. - Limited pilot’s experience – a contributor. Although highly experienced in fixed-wing aviation, the AL had no prior experience with rotary-wing aircraft, a state of affairs that led him to execute the takeoff inappropriately.
