Narrative:
The aircraft, operated by the Presidential Implementation Committee on Maritime Safety and Security (PICOMSS), departed Benin Airport for a low level range navigation south of the airfield with two crew members on board and was airborne at 10:02 hrs with endurance of 4 hrs. The two pilots were Nigerians and Nigerian Air Force personnel. 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 10:20hrs. The crew reported ‘ops normal’ and requested rejoining for some touch and go. After the fourth touch and go at 10:54hrs, the crew called Benin at 10:58hrs 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 airplane operated for the Presidential Implementation Committee on Maritime Safety and Security.

Nobody was injured.

Causal Factor
The decision of the crew to continue the glide approach despite repeated landing gear warnings with the power lever below 25% rather than initiating a Goaround.
Contributory Factors:
- The failure of the crew to recognize the landing gear warnings.
- No Standard Operating Procedure/Training Policy in place.
- The crew low hours and experience, coupled with the rostering of two pilots with same capability on a training flight.
- Lack of Crew Resource Management (CRM) training.

Two safety recommendations were raised.
