The Accident Investigation Bureau (AIB) was notified of the serious incident at about 1200hrs on 5th July, 2012. Investigators were dispatched to the crash site same day. All relevant authorities were notified.
The aircraft departed Benin airport for a low level range navigation south of the airfield with two crew members on board and was airborne at 1002hrs with endurance of 04hrs. At about 10NM the crew was asked to confirm whether they wanted to maintain Benin frequency or go to Osubi frequency, the crew replied that they will remain with Benin and was advised to report ‘ops normal’ at 1020hrs. The crew reported ‘ops normal’ and requested rejoining for some touch and go. After the fourth touch and go at 1054hrs, the crew called Benin at 1058hrs for a full stop landing.
The crew stated that during the final approach for a full stop landing in a glide approach exercise, they were preoccupied with the procedures and failed to recognize and heed landing gear warning. However, as they made last minute attempt to select the gear down it was too late for the gear to lock down before the aircraft touched down. The aircraft touched down with the gears in transit and the gears collapsed under the weight of the aircraft.
The aircraft first point of touchdown was at about 3,609ft (1,100m) from the threshold of runway 05. The aircraft belly rolled for another 656ft (200m) before veering-off the runway into the grass area.
The Federal Airports Authority of Nigeria (FAAN) and the Nigerian Air Force (NAF) Fire Services responded immediately by sending their Rapid Response Vehicles to the crash site, in readiness to combat any fire outbreak.
