Event Summary
During the takeoff roll, as the aircraft reached approximately 60 feet above ground level, the pilot noticed the airspeed indicator reading drop below 40 mph. The engine sounded normal. The pilot lowered the nose, but the airspeed indicator remained below 40 mph, prompting the decision to abort the takeoff.
During the abort, the aircraft touched down 600 feet beyond the end of the 5,000-foot runway. After the first touchdown, the aircraft bounced and traveled 170 feet before a second touchdown, then bounced again and traveled another 65 feet before a third touchdown. It subsequently collided with a berm and a chain-link fence, then traveled an additional 320 feet before coming to rest.
Damage and Inspection
All three landing gear separated from the aircraft. Extensive damage was noted to the nose section, belly, right wing, and fuselage. Both propeller blades were curled rearward and exhibited considerable twisting, bending, edge gouging, and chordwise scratching.
The pitot system was checked, and no system leaks were found. The airspeed indicator was tested and found to be within 1 mph of comparator indications.
Probable Cause
Not stated.
