Crew was peforming a cargo flight from Abidjan to Lagos with an intermediate stop in Accra. On approach to Lagos, weather was poor with ceiling 100 feet above minimum, heavy rain falls, visibility 1,000 meters and winds from 080 degrees at 18 knots gusting 30 knots. Copilot was peforming the approach and landing and aircraft touch down at a speed of 167 knots (30 knots above Vref) and 1,427 metres after the runway threshold. Thrust reversers were deployed but captain realised he could not stop the aircraft within the remaining runway so he decided to abort and to started a go around procedure. Thrust reversers were briefly stowed and then re-deployed again. Aircraft overran at a speed of 80 knots, went through the localizer antenna, lost its nose gear and came to rest 400 metres past the runway end. All three occupants were uninjured while the aircraft was considered as damaged beyond repair.
Decision of the crew to continue an unstabilised approach despite the prevailing adverse weather condition.
The following factors were considered as contributory:
Captain did not take over the control of the flight from the first officer in the known bad weather situation.
Crew resource management was inadequate.
