On 24 May, 2011 at 11:54 h, a Beechcraft C90 aircraft with nationality and registration marks N364UZ, operated by Shoreline Energy International Limited (SEIL), departed Old Kaduna (Military) airport on a test flight with a pilot and an engineer onboard, three hours’ endurance on a visual flight rules (VFR) flight plan.
According to an eye witness the aircraft sound was unusual and the aircraft seemed not to be gaining altitude after takeoff.
According to another eyewitness (a local farmer), he saw the aircraft moving up and down with increasing and decreasing engine sound. It impacted a mango tree turned and crashed. The local farmer and some military personnel tried all they could to rescue the aircraft occupants but it proved abortive. The aircraft burst into flames.
