A cargo aircraft overran the wet runway after landing, veered left, and suffered left main gear collapse. The reverse thrust system on engine #4 failed. All six crew escaped uninjured.

Accident Overview

After an uneventful cargo flight from Paris, the crew completed a night landing on runway 05. Upon touchdown, the crew initiated the braking procedure by selecting spoilers and reverse thrust.

Sequence of Events

Shortly after touchdown, the aircraft began veering to the left. In response, the captain reduced the use of the reverse thrust systems. The runway surface was wet, and the aircraft was unable to stop within the remaining distance. It overran the runway end at a speed of 10 knots.

Damage and Outcome

The aircraft sank into soft ground beyond the runway, causing the left main landing gear to collapse. The aircraft came to rest approximately 50 metres past the runway end. It sustained damage beyond repair. All six crew members on board escaped uninjured.

Cause

The probable cause, as stated in the official investigation, is that the reverse thrust system failed on engine n°4.
