Hydro Air Cargo's Boeing 747 freighter ZS-OOS was operating on a cargo flight from Brussels (BRU) to Johannesburg (JNB) with an intermediate stop at Lagos (LOS). A Notam stated that runway 19R, a 3900 x 60 meters asphalt runway, was closed because of resurfacing work. During the descent the controller at Lagos told the crew that 19R was in use. After a query by the Hydro crew he made the correction and reported that the runway in use was 19L. Apparently the approach controller cleared the flight to land on 19R. On landing the Boeing struck stacks of asphalt and the aircraft slewed left with its first engine in contact with the surface until the nose wheel came to rest in a drainage ditch.

Probable Cause:

The AIPB reported that the Nigerian Civil Aviation Authority did not know of the closure of the runway, nor that it was aware of the NOTAM until the accident occurred. Runway 19R was not properly closed in accordance with standard practice, as the runway lights were all switched on indicating runway serviceability.
