Beschrijving:
The Metro III airplane took off from Bogotá-Eldorado Airport (BOG) on a passenger flight to Carepa. During the descent the first officer was Pilot Flying.
During the approach the captain took over control. During the approach the airplane was operated by the crew with a lack of discipline and poor CRM.
The ground proximity alarm activated seven times during the approach, but the crew did not make any correcting maneuvers. They descended below obstacle clearance height. At a height of 200 feet on finals one of the engines indicated a failure. The pilot did not fly the plane within the parameters required to operate with one engine inoperative. The stick-pusher alarm activated, warning the pilot of an impending stall. The pilot made no attempt to avoid the stall. With undercarriage down and full flaps the airplane stalled and impacted with terrain approximately 300 feet short of runway 33.

- Lack of approved procedures, directives and instructions.
- The absence of CRM procedures and low situational awareness.
- The lack of evasive action when the ground proximity warning system's alarm sounded.
- The sudden loss of power in one of the engines.
