What happened
Following the closure of Santos Dumont Airport due to heavy fog, an aircraft was forced to divert to Galeão Airport. After passengers had already disembarked at the diversion site, the crew attempted a brief ferry flight back to the original destination once visibility improved.
Upon arriving at Santos Dumont Airport, the aircraft landed on runway 02. During the landing roll, the plane failed to decelerate sufficiently within the available runway length. This resulted in an overrun that caused the aircraft to plunge into Guanabara Bay. The incident resulted in five injuries among the crew members, and the aircraft was destroyed.
Findings
Investigations determined that the primary factor in the accident was an incorrect approach configuration by the flight crew, which led to the aircraft touching down too far down the runway, leaving insufficient distance for a safe stop.
