Airspeed Indicator Anomaly Leads to Takeoff Abort and Runway Overrun

Accident Sequence

The pilot reported that the airspeed indicator was not displaying normal values as the airplane accelerated during the takeoff roll. After identifying the anomaly, she continued the takeoff roll for an unspecified distance before ultimately deciding to abort the takeoff. The runway surface had an accumulation of dew on the grass.

During the rejected takeoff, the airplane overran the end of the runway, slid down an embankment, and nosed over in a ravine. Both wings sustained substantial damage.

Investigation Findings

An inspection of the airplane revealed that the pilot had not removed the pitot-tube protective cover before departure.
