Intercontinental de Aviación Flight ITC256 was scheduled to depart at 12:10 on a service to Cartagena and San Andres Island. The flight was delayed because of a malfunction on the previous flight. Maintenance work had to be carried out on the electrical system.

The flight finally departed at 18:45 after a delay of over six hours. At 19:09 the contacted the Bogota Center controller and reported en route at FL310. At 19:26 Barranquilla Control cleared the flight to start the descent from FL310 to FL140 and to report passing FL200. They passed FL200 at 19:33 and were instructed to contact Barranquilla Approach.

– Cause:

“PROBABLE CAUSE:

The probable cause of this accident was the loss of situational awareness by the crew.

CONTRIBUTING FACTORS:

Contributing to the loss of Vertical Situational Awareness, was the failure of the altimeter Number one during the descent, the lack of light in the altimeter Number two, the ineffectiveness of the Altitude Alert due to the failure of the altimeter Number one, the lack of radar service in the area, the complacency of the command crew because of good weather conditions, flight training that may not have been authorized by the company, the failure of the ground proximity warning system (GPWS), or lack of crew reaction time to respond to this alarm.”
