Aircraft Accident/Incident Report
West Chester, Pennsylvania 19380
Monday, May 21, 2001 9:55 EDT
NTSB Narrative Summary Released at Completion of Accident
The pilot reported that the airspeed indicator would not exceed 65 knots during the takeoff roll. He aborted the takeoff, but the airplane continued off the end of the runway, and came to rest in a parking lot. An airspeed calibration test was performed, and the airspeed indicator read about 10 knots higher than the test equipment. Further examination of the system revealed that the pitot tube was blocked with a "corrosion-type material". The airspeed indicator was then removed from the airplane and bench tested. The indicator read about 4-5 knots higher than the test equipment. The most recent pitot-static system check was performed on March 14, 2001.
NTSB Probable Cause Narrative
The partial blockage of the pitot/static system, which led to an inaccurate airspeed indication, and resulted in an aborted takeoff and runway overrun. A factor was the wet runway.
