The helicopter was operating a non-scheduled flight from Port Harcourt to Lagos with a proposed re-fuelling stop at Ward. The estimated time of departure from Port Harcourt was 1305 local time, flying on visual flight rules in clear weather. The Captain, Zsolt Batorfi gave his estimated time of arrival in Warri as 1405. The last contact with Port Harcourt was at 1319 when the helicopter reported at the Control Zone Boundary-20 Nautical Miles.
Contact was made with the Warri Aero Contractors Radio Room at 1359.
The Pilot was making a descent from 34.8m approximately 10 minutes out from Warri when he heard a metallic sound and the helicopter immediately spun violently to the left losing height. The pilot made a frantic attempt to reduce the rate of fall by increasing the collective pitch of the main rotor blades.
