NTSB investigators used data provided by various sources and may not have traveled in support of this investigation to prepare this aircraft incident report.
The airplane rotated approximately 500 feet from the intersection of runway 15R and taxiway M as the vehicle cleared the runway edge southbound on taxiway M. Taxiway M was under construction to connect the northern and southern portions for a full-length parallel taxiway. The operator of the construction vehicle was just coming on shift at the construction site at taxiway M. The Airport Authority had designated the south haul route as active at the time of the incident. The operator of the construction vehicle departed the construction trailer and drove to the construction site via the north haul route. He recalled turning on the construction vehicle’s rotating lights and the radio. He made no radio contact with the tower air traffic controllers during the drive, and despite not seeing any stop signs in place indicating a closed runway or looking both ways at the intersection, crossed the active runway without clearance. The operator of the vehicle stated in his interview he was “on autopilot during the drive to the construction site” and “was preoccupied” with thoughts of what needed to be done at the construction site.
The National Transportation Safety Board determines the probable cause(s) of this incident to be: The vehicle operator's failure to follow the designated haul route to the construction site and his failure to adhere to airport driving procedures, which led to missed visual cues and lack of required communication prior to crossing the active runway. Contributing to the incident was the vehicle operator's distraction. Full narrative available
