What happened
On January 10, 1966, a cargo aircraft was performing a nighttime transport mission to Ecuador, transporting a shipment of cigarettes. During the flight, the plane encountered intense rainfall and subsequently collided with a mountain slope in the vicinity of Urrao. Following the failure of the aircraft to reach its intended destination, search and rescue operations were initiated.
The wreckage was eventually located on the slopes of Mt Cerro Pelado, situated between the towns of Frontino and Urrao. The impact resulted in the total destruction of the airframe. There were four fatalities among the occupants of the flight.
Findings
Investigations into the crash determined that the aircraft was being operated by Vicair under a lease arrangement involving Atlantic Aircraft Corporation and Associated Aviation Industries. The primary factor contributing to the accident was controlled flight into terrain during adverse weather conditions.
