Narrative:

Runway incursion occurred at ont airport. My taxi instructions were to taxi to runway 26L via taxiway K, taxiway M, and taxiway Q. The route crossed runway 26R (which was closed) at taxiway K. From terminal, the route took me across runway 26R at taxiway K with a left turn at taxiway M to the intersection of runway 26L and taxiway 1. I did not stop until I realized that I had crossed the hold short lines. As I came to a stop I saw caravan rotate on runway 26L, our separation was still safe. I was able to stop my aircraft outside of the physical boundaries of runway 26L. I feel a big factor was that taxiway K is a high speed turnoff and therefore a large distance exists between the actual runway and the hold short lines. Since I was still far from the physical boundaries of runway 26L, I was complacent and did not realize I was crossing the hold short lines. Another factor was a new route that I had not been on before. I reviewed the airport diagram before taxi and felt that I was familiar enough with the taxi route assigned. I am surprised and disappointed in myself that I was not more aware operating in a sensitive environment as ont. I feel the way to avoid an incident like this is to absolutely do nothing on the taxi but focus on your route, instead of being distraction by things inside the cockpit.

Title: C208 PLT HAS RWY INCURSION AT ONT, AS ANOTHER C208 IS ON INITIAL TKOF.

Narrative: RWY INCURSION OCCURRED AT ONT ARPT. MY TAXI INSTRUCTIONS WERE TO TAXI TO RWY 26L VIA TXWY K, TXWY M, AND TXWY Q. THE RTE CROSSED RWY 26R (WHICH WAS CLOSED) AT TXWY K. FROM TERMINAL, THE RTE TOOK ME ACROSS RWY 26R AT TXWY K WITH A L TURN AT TXWY M TO THE INTXN OF RWY 26L AND TXWY 1. I DID NOT STOP UNTIL I REALIZED THAT I HAD CROSSED THE HOLD SHORT LINES. AS I CAME TO A STOP I SAW CARAVAN ROTATE ON RWY 26L, OUR SEPARATION WAS STILL SAFE. I WAS ABLE TO STOP MY ACFT OUTSIDE OF THE PHYSICAL BOUNDARIES OF RWY 26L. I FEEL A BIG FACTOR WAS THAT TXWY K IS A HIGH SPD TURNOFF AND THEREFORE A LARGE DISTANCE EXISTS BTWN THE ACTUAL RWY AND THE HOLD SHORT LINES. SINCE I WAS STILL FAR FROM THE PHYSICAL BOUNDARIES OF RWY 26L, I WAS COMPLACENT AND DID NOT REALIZE I WAS XING THE HOLD SHORT LINES. ANOTHER FACTOR WAS A NEW RTE THAT I HAD NOT BEEN ON BEFORE. I REVIEWED THE ARPT DIAGRAM BEFORE TAXI AND FELT THAT I WAS FAMILIAR ENOUGH WITH THE TAXI RTE ASSIGNED. I AM SURPRISED AND DISAPPOINTED IN MYSELF THAT I WAS NOT MORE AWARE OPERATING IN A SENSITIVE ENVIRONMENT AS ONT. I FEEL THE WAY TO AVOID AN INCIDENT LIKE THIS IS TO ABSOLUTELY DO NOTHING ON THE TAXI BUT FOCUS ON YOUR RTE, INSTEAD OF BEING DISTR BY THINGS INSIDE THE COCKPIT.
