Event Location
Probable Cause
The pilot’s failure to remove the pitot tube cover during the preflight inspection, which resulted in his delayed decision to reject the takeoff with insufficient runway remaining to safely stop the airplane.
Full Narrative
The pilot of the twin-engine airplane reported that during the takeoff roll on the 3,500-foot runway the airplane's airspeed indicator did not indicate an airspeed, so he rejected the takeoff. He added that, he attempted to brake, but "full braking [was] not initially possible due to lift". Subsequently, the airplane overran the runway onto a downhill grass area and struck a wood fence.
During a post-accident inspection the pilot discovered that the pitot tube cover had not been removed before the flight.
According to the manufacturer, the typical takeoff roll is approximately 1,336 feet and the approximate landing roll is 1,440 feet.
The airplane sustained substantial damage to both wings.
The pilot reported that there were no preaccident mechanical failures or malfunctions with the airplane that would have precluded normal operation.
The pilot added that his preflight memory list was: fuel, oil, tires, props, and surfaces. He will now add, "chocks, cowl plugs, pitot tube covers".
