What happened
While performing the takeoff roll, the aircraft experienced a sudden loss of hydraulic pressure. In response to this mechanical failure, the crew initiated an aborted takeoff procedure. Despite attempts to utilize emergency braking techniques, the aircraft could not decelerate sufficiently before reaching the end of the runway.
As a result of the insufficient stopping distance, the plane exited the runway and entered Guanabara Bay. All passengers and crew members were successfully evacuated from the vessel without injury. Shortly after the impact with the water, the aircraft submerged.
Findings
- The primary factor in the accident was a failure of the hydraulic system.
- The loss of hydraulic pressure rendered standard braking ineffective during the high-speed portion of the takeoff roll.
