What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) During acceleration in the takeoff roll (of a touch and go) at Camas County Airport U86, pilot proceeded to raise the flaps to the takeoff setting. Due to a momentary reduction in lift, the weight of the aircraft increased, causing the main tires to sink into the unexpectedly deep snow covering the runway. The force of drag caused by the deep snow completely stopped the main wheels. In an instant, the aircraft rotated forward onto its nose and struck the prop.
