Narrative:

We were cleared to taxi to runway 15 at bur to hold short of runway 08/26 at the base of the tower. I taxied west to what looked like a hold line for runway 15/33 near the base of the tower and stopped, facing west. I was confident I knew where the parallel taxiway for runway 15/33 was, even though I couldn't see it out the first officer's side window. We were cleared to cross 08/26. I simultaneously pushed up the power, scanning for traffic and trying to make sure I wasn't taxiing over any runway or taxiway lights and started an immediate right turn, which I shallowed out when it appeared I was undershooting the turn to the 'taxiway.' bur ground control and the first officer simultaneously gave warning that I was turning onto runway 15, but it was too late. We were already on the runway and a light aircraft, attempting to land on runway 15, was on the go around. I would not call it a near miss, thanks to an alert tower operator or the other pilot, I don't know which. It was a great day, I felt really good and very confident. That probably diminished my usual wariness, and having flown into bur a # of times lately I was getting very comfortable with its layout and peculiarities. I must add that bur is a confusing airport, visually. There is so much asphalt of different shades and textures, with many markings of various prominence and vintage, in taxiing 'to the base of the tower' I actually went beyond the turning point for a normal 90-110 degree turn onto the parallel to an apparent but faint hold line. In my right turn, the opening for the taxiway was far enough behind the aircraft that I never picked it up and confidently chose the runway as the taxiway. Supplemental information from acn 145646: suddenly I realized that the captain was not completing the turn toward the taxiway, but was proceeding onto runway 15 instead. He stopped when I pointed out the error and indicated the correct taxiway to him, but immediately thereafter we saw a light plane make a go around at the approach end of runway 15. The ground controller then told us that we had caused a go around by encroaching on the active runway. Had I stamped on the brakes at the first inkling of doubt about my captain's intentions, we would not have made the runway incursion. There was only time enough for action, not discussion, to prevent the incident, and it's difficult to bring yourself to interfere with the captain's control of the aircraft. Nonetheless, a copilot has to be prepared for that possibility. Act now--discuss later.

Title: ART MLG TAXIES ONTO RWY IN MISTAKEN BELIEF THAT IT IS THE ENTRY FOR A TXWY.

Narrative: WE WERE CLRED TO TAXI TO RWY 15 AT BUR TO HOLD SHORT OF RWY 08/26 AT THE BASE OF THE TWR. I TAXIED W TO WHAT LOOKED LIKE A HOLD LINE FOR RWY 15/33 NEAR THE BASE OF THE TWR AND STOPPED, FACING W. I WAS CONFIDENT I KNEW WHERE THE PARALLEL TXWY FOR RWY 15/33 WAS, EVEN THOUGH I COULDN'T SEE IT OUT THE F/O'S SIDE WINDOW. WE WERE CLRED TO CROSS 08/26. I SIMULTANEOUSLY PUSHED UP THE PWR, SCANNING FOR TFC AND TRYING TO MAKE SURE I WASN'T TAXIING OVER ANY RWY OR TXWY LIGHTS AND STARTED AN IMMEDIATE RIGHT TURN, WHICH I SHALLOWED OUT WHEN IT APPEARED I WAS UNDERSHOOTING THE TURN TO THE 'TXWY.' BUR GND CTL AND THE F/O SIMULTANEOUSLY GAVE WARNING THAT I WAS TURNING ONTO RWY 15, BUT IT WAS TOO LATE. WE WERE ALREADY ON THE RWY AND A LIGHT ACFT, ATTEMPTING TO LAND ON RWY 15, WAS ON THE GAR. I WOULD NOT CALL IT A NEAR MISS, THANKS TO AN ALERT TWR OPERATOR OR THE OTHER PLT, I DON'T KNOW WHICH. IT WAS A GREAT DAY, I FELT REALLY GOOD AND VERY CONFIDENT. THAT PROBABLY DIMINISHED MY USUAL WARINESS, AND HAVING FLOWN INTO BUR A # OF TIMES LATELY I WAS GETTING VERY COMFORTABLE WITH ITS LAYOUT AND PECULIARITIES. I MUST ADD THAT BUR IS A CONFUSING ARPT, VISUALLY. THERE IS SO MUCH ASPHALT OF DIFFERENT SHADES AND TEXTURES, WITH MANY MARKINGS OF VARIOUS PROMINENCE AND VINTAGE, IN TAXIING 'TO THE BASE OF THE TWR' I ACTUALLY WENT BEYOND THE TURNING POINT FOR A NORMAL 90-110 DEG TURN ONTO THE PARALLEL TO AN APPARENT BUT FAINT HOLD LINE. IN MY RIGHT TURN, THE OPENING FOR THE TXWY WAS FAR ENOUGH BEHIND THE ACFT THAT I NEVER PICKED IT UP AND CONFIDENTLY CHOSE THE RWY AS THE TXWY. SUPPLEMENTAL INFO FROM ACN 145646: SUDDENLY I REALIZED THAT THE CAPT WAS NOT COMPLETING THE TURN TOWARD THE TXWY, BUT WAS PROCEEDING ONTO RWY 15 INSTEAD. HE STOPPED WHEN I POINTED OUT THE ERROR AND INDICATED THE CORRECT TXWY TO HIM, BUT IMMEDIATELY THEREAFTER WE SAW A LIGHT PLANE MAKE A GAR AT THE APCH END OF RWY 15. THE GND CTLR THEN TOLD US THAT WE HAD CAUSED A GAR BY ENCROACHING ON THE ACTIVE RWY. HAD I STAMPED ON THE BRAKES AT THE FIRST INKLING OF DOUBT ABOUT MY CAPT'S INTENTIONS, WE WOULD NOT HAVE MADE THE RWY INCURSION. THERE WAS ONLY TIME ENOUGH FOR ACTION, NOT DISCUSSION, TO PREVENT THE INCIDENT, AND IT'S DIFFICULT TO BRING YOURSELF TO INTERFERE WITH THE CAPT'S CONTROL OF THE ACFT. NONETHELESS, A COPLT HAS TO BE PREPARED FOR THAT POSSIBILITY. ACT NOW--DISCUSS LATER.
