What happened
During a local training session at São Paulo-Congonhas Airport, the crew was performing a series of touch-and-go maneuvers. Shortly after departing the runway and entering the initial climb phase, the aircraft type became uncontrollable. The flight path ended in a crash approximately 7,450 meters from the airport boundaries.
The impact resulted in the total destruction of the plane. The accident caused the deaths of both pilots and one person on the ground.
Findings
Investigation into the event revealed that the aircraft was attempting to climb while operating with at least one engine inoperative, and potentially two engines non-functional. The primary factor in the loss of control was insufficient airspeed during the climb under these degraded power conditions. It is suggested that the crew may have miscalculated the performance capabilities and limitations of the aircraft while flying with reduced engine power.
