Description

The DHC-6 Twin Otter veered off runway 05 at Kairik Airstrip during takeoff and ran into a ditch, sustaining substantial damage. During the take-off roll, the aircraft veered to the left of the runway. The crew attempted to correct this by applying right rudder and asymmetric power. However, the aircraft continued veering left onto the grass surface. The flight crew decided to abort the takeoff and applied full reverse thrust and brakes. The grass was wet due to rain on the accident day and the days before, causing the aircraft to slide into a drainage ditch. The aircraft sustained substantial damage to its left wing and nose.
