SYNOPSIS
While the aircraft, a tail-wheeled Piper Cub, was backtracking at Navan Airfield, Co. Meath, the Pilot experienced increasing resistance to aircraft movement which necessitated increased engine power to maintain taxi speed. On encountering an upward-sloping section of the airfield, further application of engine power resulted in the aircraft tipping forward onto its nose and the propeller striking the grass surface. The Pilot exited the aircraft unaided and no injuries were reported.
