Narrative:
During acceleration in the takeoff roll (of a touch-and-go); I 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 tail dragger rotated forward onto its nose and struck the propeller.
Original NASA ASRS Text
Title: PA18 PLT SHOOTING TOUCH AND GO LANDINGS ON A SNOW COVERED TURF RWY NOSES OVER ON TKOF ROLL WHEN WHEELS SINK INTO SNOW.
Narrative: DURING ACCELERATION IN THE TKOF ROLL (OF A TOUCH-AND-GO); I PROCEEDED TO RAISE THE FLAPS TO THE TKOF SETTING. DUE TO A MOMENTARY REDUCTION IN LIFT; THE WT OF THE ACFT INCREASED CAUSING THE MAIN TIRES TO SINK INTO THE UNEXPECTEDLY DEEP SNOW COVERING THE RWY. THE FORCE OF DRAG CAUSED BY THE DEEP SNOW COMPLETELY STOPPED THE MAIN WHEELS. IN AN INSTANT; THE TAIL DRAGGER ROTATED FORWARD ONTO ITS NOSE AND STRUCK THE PROP.
