Accident Details
During the takeoff roll on a 2,400-foot-long runway, the pilot observed that the aircraft's acceleration was slow. At approximately three-fifths of the way down the runway, the airspeed remained below 55 knots. The pilot elected to abort the takeoff. However, the aircraft overran the end of the runway, crossed a road, and collided with poles before the pilot could bring it to a stop.
Investigation Findings
Examination of the aircraft's pitot-static system revealed that the static port was completely clogged by a gummy substance, and the pitot port was partially clogged by a coiled leaf. Following cleaning, functional testing of the pitot-static system was satisfactory. No other malfunctions or anomalies were reported.
