Circumstances:
During preflight preparation for departure from a short field the pilot failed to remove the Pitot tube covers. On takeoff roll, the stall warning light began to flicker. Pilot noted airspeed was not registering but did not consider this unusual in the early part of a takeoff roll. Pilot turned left stall warning switch off, then back on, warning light remained on. Pilot then initiated abort procedures, using full reverse thrust and brakes. The aircraft overran runway by about 100 feet and down a rough embankment which separated the landing gear.
