A flight crashed into a mountain slope near Tegucigalpa-Toncontin Airport during its approach, resulting in the loss of all three crew members.

What happened

During an approach to Tegucigalpa-Toncontin Airport, an aircraft encountered adverse weather conditions. While navigating the descent, the crew did not identify that the plane had descended to an insufficient altitude. Consequently, the aircraft collided with the southern slope of Cerro de Hula, a peak reaching 1,600 meters, situated approximately 14 km from the threshold of runway 01.

The impact resulted in the total destruction of the aircraft. There were three fatalities among the crew members on board.

Findings

Investigations into the accident indicate that the primary factor was the crew's failure to maintain the required altitude while operating in poor visibility and difficult weather conditions.

Probable cause

The crew failed to maintain a safe altitude during the approach in poor weather, leading to a collision with terrain.
