Rio Branco-Presidente Médici

Poor approach configuration on part of the flying crew who continued the approach after passing the MDA at 1,150 feet while the aircraft was not stabilized and the crew did not establish a visual contact with the obstacles on short final. The following contributing factors were identified:
- Following the first impact with trees, branches and pieces of wood entered the engines, causing a loss of power followed by a loss of speed and altitude,
- Complacency on the part of the crew,
- Pressure and stress,
- Visual perception issues,
- Violation of the standard operating procedures,
- Loss of situational awareness,
- Lack of crew resources management,
- Poor approach and landing planning,
- Poor weather conditions,
- Relative low experience of the copilot.

The exact cause of the accident could not be determined with certainty. However, it is believed that the accident was the consequence of a controlled flight into terrain after the crew continued the approach in poor weather conditions and descended below the MDA until the aircraft, in a flaps and gear down configuration, impacted ground. The following contributing factors were identified:
- A difference of 70 feet in the settings was noted between both pilot's altimeters,
- Poor crew coordination,
- Complacency on part of the flying crew caused several deviations from procedures during the approach,
- Lack of crew resources management,
- The crew failed to check the altitude during the final stage of the approach,
- Poor weather conditions.

Failure of both engines on final approach due to fuel exhaustion following three unsuccessful approaches. The following contributing factors were reported:
- Poor weather conditions,
- Poor visibility,
- Poor flight planning,
- Lack of Company assistance,
- Operational deficiencies,
- Infrastructures deficiencies.
