Incident Overview
Description
The Metro III airplane took off from Bogot -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. CAUSAS PROBABLES: El juicio equivocado de la distancia, la velocidad, la altitud y el margen de franqueamiento de obst culos en la aproximaci¢n final, intentando la operaci¢n m s all ele la experiencia y nivel de competencia requerida en el equipo. El encontrar circunstancias imprevistas superiores a la capacidad de la tripulaci¢n, desviando la atenci¢n en la operaci¢n de la aeronave. CAUSAS CONTRIBUYENTES: – La falta de seguimiento de procedimientos, directivas e instrucciones aprobados. – La ausencia de procedimientos de CRN1 y baja conciencia situacional. – La falta de acci¢n evasiva cuando se present¢ la alarma del sistema de advertencia de proximidad del terreno. – La perdida de potencia s£bita en alguno de los motores. – La utilizaci¢n equivocada de los mundos principales de vuelo para mantener el control direccional. – La activacion del sistema de aumento de la estabilidad (SAS) sobre la columna el e control, desplaz ndola hacia delante estando el avi¢n a baja altura. Probable cause: The wrong judgement of distance, speed, altitude and the obstacle clearance during the final approach, attempting the operation beyond the experience and the high level of competence required by the crew. Encountering unforeseen circumstances exceeded the capacity of the crew, diverting attention on the operation of the aircraft. Contributing causes: – 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. – The wrong use of the worlds major flight to maintain directional control. – The activation of the Stall Avoidance System (SAS) on the control column, moving it forward when the plane was at low altitude.
Primary Cause
The incident was likely caused by a combination of factors related to inadequate procedures, insufficient situational awareness, and a lapse in pilot judgment regarding distance, speed, altitude, and obstacle clearance during the final approach. The crew’s lack of proper CRM, combined with the failure to react appropriately to the ground proximity alarm and the loss of engine power, significantly contributed to the incident.The incident was likely caused by a combination of factors related to inadequate procedures, insufficient situational awareness, and a lapse in pilot judgment regarding distance, speed, altitude, and obstacle clearance during the final approach.
