Narrative:

I was cleared for a touch and go for runway 27L at gellespie field (see) and had just touched down. I was going to start taking off but I noticed a low wing, single engine plane which apparently had ignored the hold short instructions. It was taxiing onto the runway and at that point, I began braking hard. The low wing turned away and gave me an extra few ft to stop, or else I might have collided with it. It was also fortunate I was fling a high wing and it was a low wing, which again would have increased the likelihood of a collision. I am convinced the fault was with the airplane, which ignored the hold short instructions. The tower controller at gellespie agreed with me on this in a later phone conversation.

Narrative: I WAS CLRED FOR A TOUCH AND GO FOR RWY 27L AT GELLESPIE FIELD (SEE) AND HAD JUST TOUCHED DOWN. I WAS GOING TO START TAKING OFF BUT I NOTICED A LOW WING, SINGLE ENG PLANE WHICH APPARENTLY HAD IGNORED THE HOLD SHORT INSTRUCTIONS. IT WAS TAXIING ONTO THE RWY AND AT THAT POINT, I BEGAN BRAKING HARD. THE LOW WING TURNED AWAY AND GAVE ME AN EXTRA FEW FT TO STOP, OR ELSE I MIGHT HAVE COLLIDED WITH IT. IT WAS ALSO FORTUNATE I WAS FLING A HIGH WING AND IT WAS A LOW WING, WHICH AGAIN WOULD HAVE INCREASED THE LIKELIHOOD OF A COLLISION. I AM CONVINCED THE FAULT WAS WITH THE AIRPLANE, WHICH IGNORED THE HOLD SHORT INSTRUCTIONS. THE TWR CTLR AT GELLESPIE AGREED WITH ME ON THIS IN A LATER PHONE CONVERSATION.
