What happened
During a routine flight, the crew performed an approach and landed at Santos Dumont Airport. Upon touching down on a runway that was wet at the time, the aircraft was unable to decelerate sufficiently within the available runway length. This led to an overrun where the plane exited the paved surface and entered Guanabara Bay.
Despite the severity of the excursion, all 31 occupants were successfully evacuated from the wreckage without sustaining any injuries. The aircraft itself was a total loss following the incident.
Findings
Investigations into the accident identified that the crew performed the landing with an incorrect approach configuration. This error resulted in the aircraft maintaining an excessive speed during the touchdown phase. Additional contributing elements included the presence of a tailwind component and the reduced braking effectiveness caused by the wet runway surface.
