Narrative:

After landing on runway 25L we exited onto taxiway M. The tower instructed us to hold short of runway 25R which we acknowledged. As we cleared the runway I removed the approach plate from on top of the airport chart. The sun was low in the sky and we were taxiing directly into it. Combined with the haze it made a very intense glare to taxi into. The first yellow line that I noticed I thought was the line to clear runway 25L. Any caution lights associated with that line were not obvious to me (I suppose because of the sun's glare). The next line I saw was the white runway edge marking for runway 25R. At that point, the nose of the aircraft was already passing over the yellow line. I applied brakes, about the same time the tower again issued instructions to hold short of runway 25R. When the aircraft stopped, it appeared to me that the yellow line was somewhere under the engines. I feel that the glare from the sun had a lot to do with this as many times in the past exiting onto a high speed turnoff and holding short as instructed had never been a problem. Our company SOP's were followed exactly. For the short amount of time that my eyes were diverted from outside to switch to a different chart we must have passed the first yellow line, I just never saw it. Even though I acknowledged the hold short instructions to my first officer if I had added to that something like 'do you see where that is' it would have opened a discussion that may have made me aware that the yellow line I was looking at was in fact the hold short line. Callback conversation with reporter revealed the following information: the reporter said he does not routinely use sun glasses or the aircraft sun shades. When reconsidering this incident, he says that he can now see a need for that and the anticipation of sun position after runway exit in this and similar sits where low to the horizon sun position could be a problem. While the reporter's aircraft was protruding into the runway safety area the tower cleared a F100 for takeoff. As it went by, it was approximately 450 ft AGL and over the centerline of the runway. During debrief with the lax tower the next day he was told that taxiway K and M are two of the locations where incursions are a problem at lax and the controllers watch for it.

Title: AN ACR CROSSES THE RWY HOLD SHORT LINE WHEN THE SETTING SUN CAUSES GLARE THAT MADE THE LINES DIFFICULT TO SEE.

Narrative: AFTER LANDING ON RWY 25L WE EXITED ONTO TXWY M. THE TWR INSTRUCTED US TO HOLD SHORT OF RWY 25R WHICH WE ACKNOWLEDGED. AS WE CLRED THE RWY I REMOVED THE APCH PLATE FROM ON TOP OF THE ARPT CHART. THE SUN WAS LOW IN THE SKY AND WE WERE TAXIING DIRECTLY INTO IT. COMBINED WITH THE HAZE IT MADE A VERY INTENSE GLARE TO TAXI INTO. THE FIRST YELLOW LINE THAT I NOTICED I THOUGHT WAS THE LINE TO CLR RWY 25L. ANY CAUTION LIGHTS ASSOCIATED WITH THAT LINE WERE NOT OBVIOUS TO ME (I SUPPOSE BECAUSE OF THE SUN'S GLARE). THE NEXT LINE I SAW WAS THE WHITE RWY EDGE MARKING FOR RWY 25R. AT THAT POINT, THE NOSE OF THE ACFT WAS ALREADY PASSING OVER THE YELLOW LINE. I APPLIED BRAKES, ABOUT THE SAME TIME THE TWR AGAIN ISSUED INSTRUCTIONS TO HOLD SHORT OF RWY 25R. WHEN THE ACFT STOPPED, IT APPEARED TO ME THAT THE YELLOW LINE WAS SOMEWHERE UNDER THE ENGINES. I FEEL THAT THE GLARE FROM THE SUN HAD A LOT TO DO WITH THIS AS MANY TIMES IN THE PAST EXITING ONTO A HIGH SPEED TURNOFF AND HOLDING SHORT AS INSTRUCTED HAD NEVER BEEN A PROBLEM. OUR COMPANY SOP'S WERE FOLLOWED EXACTLY. FOR THE SHORT AMOUNT OF TIME THAT MY EYES WERE DIVERTED FROM OUTSIDE TO SWITCH TO A DIFFERENT CHART WE MUST HAVE PASSED THE FIRST YELLOW LINE, I JUST NEVER SAW IT. EVEN THOUGH I ACKNOWLEDGED THE HOLD SHORT INSTRUCTIONS TO MY FO IF I HAD ADDED TO THAT SOMETHING LIKE 'DO YOU SEE WHERE THAT IS' IT WOULD HAVE OPENED A DISCUSSION THAT MAY HAVE MADE ME AWARE THAT THE YELLOW LINE I WAS LOOKING AT WAS IN FACT THE HOLD SHORT LINE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR SAID HE DOES NOT ROUTINELY USE SUN GLASSES OR THE ACFT SUN SHADES. WHEN RECONSIDERING THIS INCIDENT, HE SAYS THAT HE CAN NOW SEE A NEED FOR THAT AND THE ANTICIPATION OF SUN POS AFTER RWY EXIT IN THIS AND SIMILAR SITS WHERE LOW TO THE HORIZON SUN POS COULD BE A PROB. WHILE THE RPTR'S ACFT WAS PROTRUDING INTO THE RWY SAFETY AREA THE TWR CLRED A F100 FOR TAKEOFF. AS IT WENT BY, IT WAS APPROX 450 FT AGL AND OVER THE CTRLINE OF THE RWY. DURING DEBRIEF WITH THE LAX TWR THE NEXT DAY HE WAS TOLD THAT TXWY K AND M ARE TWO OF THE LOCATIONS WHERE INCURSIONS ARE A PROB AT LAX AND THE CTLRS WATCH FOR IT.
