Descripción:
A McDonnell Douglas DC-9-33RC cargo plane was substantially damaged in a landing accident at Saltillo Airport, Mexico.
The airplane originated in Managua, Nicaragua and operated on a non-scheduled cargo flight to Saltillo via Tapachula, Mexico.
The flight landed at Tapachula at 00:25 hours local time. An IFR flight plan was then filed for Saltillo, with Monterrey as alternate. It was not taken into account though, that Monterrey's main runway was closed that night as per Notam.
The flight departed Tapachula at 01:40. The flight was uneventful up to the approach. The aircraft carried out an ILS/DME approach to runway 17. At 04:05 the flight was cleared to land by the controller. One minute later the pilot reported going around. He stated that they would divert to their alternate, Monterrey Airport.
At 04:15 the pilot again contacted the controller at Saltillo, reporting that Monterrey Airport was closed and requesting another approach to runway 17. He radioed: "We saw runway but ehhh let's do a rough minimum approach or below the minimums".
The airplane continued the approach until it touched down to the right of the centreline and on the last third of the runway. It rolled off the side and the nose gear collapsed.

Probable Cause:

Causa Probable:
"Continuar la aproximación de precisión (ILS CAT 1) en condiciones de visibilidad reducida por niebla (sin contacto visual con la pista en un aeropuerto bajo mínimos), lo que resulto en un aterrizaje brusco y desalineado a la derecha en el último tercio de la pista, durante un segundo intento de aterrizaje, la Comisión también determinó que lo que originó a continuar con el aterrizaje fue la falta de combustible para volar a un segundo aeropuerto alterno no contemplado en la operación"

Factores contribuyentes:
1. Falta de análisis de la información operacional previa al vuelo (NOTAMs vigentes, METAR, pronósticos, combustible a un segundo aeropuerto alterno y el seguimiento del vuelo)
2. Aproximación no estabilizada
3. Falta de applicación de los conceptos de CRM
4. Falta de apego al procedimiento - operaciones, de proporcionar METAR y NOTAM a la tripulación para el despacho de la aeronave
5. Falta de apego al procedimiento para el control y seguimiento de vuelo
6. Falta de procedimientos para establecer dos aeropuertos alternos cuando el aeropuerto de destino se encuentre bajo mínimos
7. Falta de supervisión de la Companía, a la operación y vigilancia al mantenimiento de los registradores de vuelo de la aeronave
