Narrative:

A city maintenance vehicle Y crossed runway 27 in front of a departing small aircraft X. He was instructed to hold short of runway 27 and acknowledged. He was observed crossing. The departing aircraft had just begun takeoff roll and was approximately 2800' from the point of the incursion. No evasive action was necessary. The situation occurred because the vehicle driver was not paying attention. I feel that the maintenance vehicle drivers have become complacent in regard to the seriousness of runway xings because xings are made so frequently at flint. One way of preventing a recurrence is to limit the number of vehicle xings. Another might be to establish routes for the vehicles that avoid crossing the runways.

Narrative: A CITY MAINT VEHICLE Y CROSSED RWY 27 IN FRONT OF A DEPARTING SMA X. HE WAS INSTRUCTED TO HOLD SHORT OF RWY 27 AND ACKNOWLEDGED. HE WAS OBSERVED XING. THE DEPARTING ACFT HAD JUST BEGUN TKOF ROLL AND WAS APPROX 2800' FROM THE POINT OF THE INCURSION. NO EVASIVE ACTION WAS NECESSARY. THE SITUATION OCCURRED BECAUSE THE VEHICLE DRIVER WAS NOT PAYING ATTN. I FEEL THAT THE MAINT VEHICLE DRIVERS HAVE BECOME COMPLACENT IN REGARD TO THE SERIOUSNESS OF RWY XINGS BECAUSE XINGS ARE MADE SO FREQUENTLY AT FLINT. ONE WAY OF PREVENTING A RECURRENCE IS TO LIMIT THE NUMBER OF VEHICLE XINGS. ANOTHER MIGHT BE TO ESTABLISH ROUTES FOR THE VEHICLES THAT AVOID XING THE RWYS.
