This mishap involves Airbus A-310 model 221, serial numbered 329 with registration mark of 5N-AUG. It was operated by Nigeria Airways Limited as flight WT 104 and crashed in the landing phase on September 8th, 1987 at approximately 1756 hours UTC at Port-Harcourt International Airport, Rivers State.
Earlier on that day, the aircraft had operated five flights in and out of Port-Harcourt International Airport; the last three flights were made by the accident crew. The sixth one was the unfortunate incident and no technical problem had been indicated in the log books, which could be a contributory factor to the accident.
Throughout the approach and landing phases it was raining. The approach profile became unstabilized at about 45 seconds before touchdown, the landing was made off the runway centreline and the aircraft over-ran onto an unsafe shoulder. The decision to continue the approach despite the unstable approach profile was deemed a bad judgement.
