Bik Air LLC

Location: Nenana, AK 
Accident Number: WPR20CA232
Date & Time: 07/10/2020, 1700 AKD
Registration: N756DJ
Aircraft: CESSNA U206
Aircraft Damage: Substantial
Defining Event: Loss of control on ground
Injuries: 3 None
Flight Conducted Under: Part 91: General Aviation - Personal 


The pilot reported that he was performing a soft field takeoff at a private dirt airstrip with a right crosswind. During the takeoff roll, staying on the left side of the airstrip to clear a known dip, the nosewheel lifted off the ground quickly as expected, however he now had no turning ability. The pilot utilized right rudder input to compensate for the cross wind, but the ground speed was too low and he did not have enough rudder authority to keep the left wing from impacting a parked bulldozer on the side of the airstrip. The airplane's left wing was substantially damaged.

The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.

Probable Cause and Findings

The National Transportation Safety Board determines the probable cause(s) of this accident to be:
The pilot's failure to maintain directional control during a soft field takeoff on a dirt airstrip, which resulted in an impact with a vehicle.
