Cessna 182T N1491D accident near Stigler, Oklahoma

Probable cause

The loss of directional control during takeoff. Contributing to the accident was the pilot's decision to take off with 40-degrees of flaps and with a tailwind.

NTSB analysis

With winds gusting from the southeast, the private pilot elected to depart to the north from a private grass strip. During the takeoff sequence, the airplane drifted to the west of the grass strip and the airplane impacted terrain in a crab. The airplane rolled and came to rest in the inverted position. The airplane's airbag system did not deploy. No pre-impact anomalies were detected with the airframe or engine. The airbag system was tested and found to be within system tolerances. The takeoff flap setting of 40-degrees, which is not recommended by the airplane manufacturer, allowed the airplane to become airborne prior to reaching an airspeed which would allow for maximum effectiveness of the control surfaces.
