The pilot aborted takeoff after noticing the airspeed indicator was inoperative. The aircraft could not stop, ran off the runway, and entered a ditch. Inspection revealed a mud dauber nest blocking the pitot head.

Incident Details

During the takeoff roll on a 3600-foot runway, the pilot observed that the airspeed indicator was inoperative and aborted the takeoff approximately halfway down the runway. The aircraft could not be stopped before it ran off the end of the runway and entered a ditch.

Findings

An examination by an A&P mechanic determined that the pitot head was obstructed by a mud dauber nest. The obstruction was not visible through the pitot opening. The mechanic noted that this type of problem was common at that airport. The aircraft had been flown several days prior to the accident without any reported issues. The pilot operating handbook recommended that a pitot cover be used whenever the aircraft was not in use.
