Narrative:
The BAe-125 operated on a repositioning flight from Abuja to Benin City, Nigeria.
At 65 NM to Benin, the aircraft was cleared by Benin ATC to descend to FL120, subsequently to 3,500 ft, and afterwards to 2,200 ft; to commence a straight in approach to runway 23 as requested by the crew, and to report runway in sight.
The current weather report in Benin was also passed to the crew, which showed a deterioration of the weather since departure from Abuja.
The crew executed two missed approaches on runway 23 and requested to shoot an approach on runway 05. Benin ATC advised the crew of the unserviceability of the approach lights on runway 05, which the crew acknowledged.
Two landing attempts were made on runway 05. On the second attempt, the aircraft touched down past the mid-point of the wet runway, overran the runway and came to a stop on the marshy grass verge at about 450 ft beyond the end of runway 05. The engines were shut down and the three persons on board disembarked without injuries, through the passenger exit door.
The aircraft was slightly damaged.

Causal factor:
The final approach was not stable; the aircraft crossed the threshold at 395 ft AGL with airspeed of 212 k t while the Vref for landing was 122 kt.
Contributory factor
1. The aircraft touched down beyond the runway midpoint into the wet runway.
2. The decision to continue the approach despite marginal weather at destination.
3. The approved companys Standard Operating Procedure (SOP) was inadequate.
4. The Crew Resource Management (CRM) in the flight deck was poor which resulted in non-standard call-outs by the pilot monitoring (PM).
