Circumstances:
Following an uneventful flight from São Paulo-Congonhas Airport, the crew started the descent to Rio de Janeiro-Santos Dumont Airport from the north. While flying at an altitude of 5,000 feet by night and in marginal weather conditions, the crew informed ATC he just passed over AF NDB. Two minutes later, the airplane struck the slope of a mountain located near Petrópolis, about 50 km north of Santos Dumont Airport. The airplane disintegrated on impact and all 25 occupants were killed.
Probable cause:
It was determined that while descending in IMC conditions, the crew mistakenly tuned the ADF instrument to a wrong NDB, causing the airplane to follow a wrong approach path and to descend at an inappropriate altitude. The lack of visibility due to the night and clouds was considered as a contributing factor.

Circumstances:
On an ILS approach to Ponta Pelada AFB on a cargo flight from Panama City to São Paulo, the airplane was not properly aligned and was too high on the glide. The captain overcorrected, causing the airplane to adopt a high sink rate. In a nose-down attitude, the nose gear struck a concrete wall located 12 meters short of runway threshold and was torn off. The airplane landed on its nose and slid for about 300 meters before coming to rest. All three crew members escaped uninjured while the aircraft was damaged beyond repair.
Probable cause:
Wrong approach configuration on part of the pilot-in-command.

Probable cause:
The takeoff was performed with a simulated failure of the right engine. Incorrect procedure used by the instructor by simulating the engine failure below V1 and attempting to unstick the aircraft below minimum control speed.
