Analysis

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