B735, Jos Nigeria, 2010

Summary

On 24 August 2010, a Boeing 737-500 made an uncontrolled touchdown on a wet runway at Jos in daylight after the approach was continued despite not being stabilised. A lateral runway excursion onto the grass occurred before the aircraft regained the runway centreline and stopped two-thirds of the way along the 3000 metre-long runway. Substantial damage was caused to the aircraft but none of the occupants were injured. The aircraft commander was the Operator's 737 Fleet Captain and the Investigation concluded that the length of time he had been on duty had led to fatigue which had impaired his performance.

Description

On 24 August 2010, a Boeing 737-500 (5N-BLE) being operated by Aero Contractors Nigeria on a scheduled domestic passenger flight (210) from Lagos to Jos made an uncontrolled touchdown at destination after a daylight non-precision approach had become unstabilised and remained so after the visual reference transition to land. The aircraft departed the side of the runway onto the grass before regaining the centreline and stopping. Damage to the aircraft was substantial but there were no occupant injuries. Three runway light assemblies and some armoured electrical cables were also damaged.

Investigation

An Investigation was carried out by the Nigerian Accident Investigation Bureau (AIB) aided by successful download of Flight Data Recorder (FDR) and Cockpit Voice Recorder (CVR) data undertaken by the UK AAIB.

It was established that the 25 year-old First Officer had been designated as PF for the accident flight and that the 53 year-old aircraft commander was the aircraft operator's Boeing 737 Fleet Captain. He was also a Training Captain, although he had not been operating in the latter capacity on the accident flight.
