SANSA Flight 32, a CASA C-212 Aviocar on its way to Palmar Sur Airport crashed into the Cerro Cedral, a mountain in Costa Rica after takeoff from Juan Santamaría International Airport in San Jose on January 15, 1990.

SANSA Flight 32 took off from Juan Santamaria International Airport at 08:25 local time and was cleared to climb to 5500 feet.

Midway through the climb, the aircraft flew into Cerro Cedral at 7200 feet, killing all on board.

[1] The investigation found that the main cause of the accident was the failure to comply with the proposed flight plan discussed with air traffic control, which would have led the aircraft to be flying under IMC conditions instead of VFR ones.

Supporting factors include the lack of a Ground Proximity Warning System, pilot fatigue and a lack of a flight safety program in SANSA.
