On 1 December 2020, a Viking DHC6-300 crew departing Wobagen set asymmetric power in response to directional control difficulties but this did not prevent the aircraft subsequently veering off the runway and into a ditch. Both engines were found to have been operating normally and with failure to complete takeoff checks resulting in the initial setting of asymmetric power. This was then followed by an unsuccessful attempt to regain directional control on the wet and deteriorated clay/silt runway surface without reducing power. Both pilots were experienced in the use of small airstrips generally and with Wobagen in particular.
