Narrative:
Construction worker crossed intersection of runway 7/25 and runway 12/30 at ggw after I had started my departure roll for an air ambulance flight. Construction company has placed stop signs at intersection, placed a worker at the intersection with a radio to direct vehicle traffic as necessary. The company has stated they reviewed an advisory circular and amended their policy as needed. Callback conversation with reporter revealed the following information: pilot was astonished and angry that a truck pulled out in front of his aircraft just as it was lifting off. The truck was a one ton truck belonging to a worker who was part of a runway paving company. The truck had a strobe light on top of it, but there were tool boxes surrounding the strobe light which prevented the light from being seen by anyone away from the truck. The truck driver crossed the runway at a heading of 120 degrees from the takeoff path of the aircraft. The truck driver never turned the truck 90 degrees to the runway which would have permitted him to have an unobstructed view of the runway. The aircraft he should have seen was a C421 which is a large enough aircraft to be more easily seen. The truck driver was disturbed by the event, he and his supervisor reported to the chief pilot regarding the event and came up with the following resolution: 1) stop signs would be placed at all runways where ground traffic should come to a stop before crossing the runway, and 2) all vehicles that might be crossing an active runway will have a radio to monitor the unicom frequency in order to monitor arriving or departing aircraft. This is an uncontrolled airport. With the changes made after this incident, the reporter and his chief pilot feel everything is working properly and there have been no more incidents of this type.

Title: ACFT MISSES TRUCK XING RWY BY 50 FT.
Narrative: CONSTRUCTION WORKER CROSSED INTXN OF RWY 7/25 AND RWY 12/30 AT GGW AFTER I HAD STARTED MY DEP ROLL FOR AN AIR AMBULANCE FLT. CONSTRUCTION COMPANY HAS PLACED STOP SIGNS AT INTXN, PLACED A WORKER AT THE INTXN WITH A RADIO TO DIRECT VEHICLE TFC AS NECESSARY. THE COMPANY HAS STATED THEY REVIEWED AN ADVISORY CIRCULAR AND AMENDED THEIR POLICY AS NEEDED. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: PLT WAS ASTONISHED AND ANGRY THAT A TRUCK PULLED OUT IN FRONT OF HIS ACFT JUST AS IT WAS LIFTING OFF. THE TRUCK WAS A ONE TON TRUCK BELONGING TO A WORKER WHO WAS PART OF A RWY PAVING COMPANY. THE TRUCK HAD A STROBE LIGHT ON TOP OF IT, BUT THERE WERE TOOL BOXES SURROUNDING THE STROBE LIGHT WHICH PREVENTED THE LIGHT FROM BEING SEEN BY ANYONE AWAY FROM THE TRUCK. THE TRUCK DRIVER CROSSED THE RWY AT A HDG OF 120 DEGS FROM THE TKOF PATH OF THE ACFT. THE TRUCK DRIVER NEVER TURNED THE TRUCK 90 DEGS TO THE RWY WHICH WOULD HAVE PERMITTED HIM TO HAVE AN UNOBSTRUCTED VIEW OF THE RWY. THE ACFT HE SHOULD HAVE SEEN WAS A C421 WHICH IS A LARGE ENOUGH ACFT TO BE MORE EASILY SEEN. THE TRUCK DRIVER WAS DISTURBED BY THE EVENT, HE AND HIS SUPVR RPTED TO THE CHIEF PLT REGARDING THE EVENT AND CAME UP WITH THE FOLLOWING RESOLUTION: 1) STOP SIGNS WOULD BE PLACED AT ALL RWYS WHERE GND TFC SHOULD COME TO A STOP BEFORE XING THE RWY, AND 2) ALL VEHICLES THAT MIGHT BE XING AN ACTIVE RWY WILL HAVE A RADIO TO MONITOR THE UNICOM FREQ IN ORDER TO MONITOR ARRIVING OR DEPARTING ACFT. THIS IS AN UNCTLED ARPT. WITH THE CHANGES MADE AFTER THIS INCIDENT, THE RPTR AND HIS CHIEF PLT FEEL EVERYTHING IS WORKING PROPERLY AND THERE HAVE BEEN NO MORE INCIDENTS OF THIS TYPE.
