Narrative:

Ground cleared us to taxi from ramp via taxiway G, taxiway east, hold short of runway 3. Ground also mentioned that holding short of runway 3 on taxiway G not authority/authorized, (for aircraft with wing span more than 117 ft). During taxi, the captain then ran the radios while I started engines #4 and #1. Ground then cleared us to taxi taxiway G, taxiway east, runway 3 to runway 30L, monitor tower frequency. Captain replied to the clearance. While finishing engine starts and remainder of checklist and dividing my attention between cockpit duties and taxi route, I had a slight difficulty in trying to distinguish where runway 3 and runway 30L intersected, to determine position relative to runway 30L. Finally picked up visual cues and found hold short line. Noted captain's taxi speed and told him hold short line was coming up. It didn't appear captain was slowing, so I told him again, 'again, we need to hold short of runway 30. At hold short line.' captain realized hold short lien position but nose of aircraft went past line. Aircraft did not enter runway 30L. We immediately notified tower of position. Tower initiated a go around of a learjet on 3/4 mi final. Tower then cleared us for takeoff. Possible contributing factors: round about taxi route to hold short line to runway 30L. Difficulty in distinguishing runway 30L and runway 3 intersection. It appeared to me that hold short line was positioned farther from runway than usual hold short lines on txwys relative to runway. This also may not be the case due to dividing attention between taxi route and cockpit duties. Next time in sat will make mental note of hold short line.

Title: LEARJET ON FINAL APCH SENT AROUND BY TWR AFTER A DC8 FLT CREW ADVISES TWR THAT THEY HAD CROSSED THE HOLD SHORT LINE FOR RWY 30L AT SAT.

Narrative: GND CLRED US TO TAXI FROM RAMP VIA TXWY G, TXWY E, HOLD SHORT OF RWY 3. GND ALSO MENTIONED THAT HOLDING SHORT OF RWY 3 ON TXWY G NOT AUTH, (FOR ACFT WITH WING SPAN MORE THAN 117 FT). DURING TAXI, THE CAPT THEN RAN THE RADIOS WHILE I STARTED ENGS #4 AND #1. GND THEN CLRED US TO TAXI TXWY G, TXWY E, RWY 3 TO RWY 30L, MONITOR TWR FREQ. CAPT REPLIED TO THE CLRNC. WHILE FINISHING ENG STARTS AND REMAINDER OF CHKLIST AND DIVIDING MY ATTN BTWN COCKPIT DUTIES AND TAXI RTE, I HAD A SLIGHT DIFFICULTY IN TRYING TO DISTINGUISH WHERE RWY 3 AND RWY 30L INTERSECTED, TO DETERMINE POS RELATIVE TO RWY 30L. FINALLY PICKED UP VISUAL CUES AND FOUND HOLD SHORT LINE. NOTED CAPT'S TAXI SPD AND TOLD HIM HOLD SHORT LINE WAS COMING UP. IT DIDN'T APPEAR CAPT WAS SLOWING, SO I TOLD HIM AGAIN, 'AGAIN, WE NEED TO HOLD SHORT OF RWY 30. AT HOLD SHORT LINE.' CAPT REALIZED HOLD SHORT LIEN POS BUT NOSE OF ACFT WENT PAST LINE. ACFT DID NOT ENTER RWY 30L. WE IMMEDIATELY NOTIFIED TWR OF POS. TWR INITIATED A GAR OF A LEARJET ON 3/4 MI FINAL. TWR THEN CLRED US FOR TKOF. POSSIBLE CONTRIBUTING FACTORS: ROUND ABOUT TAXI RTE TO HOLD SHORT LINE TO RWY 30L. DIFFICULTY IN DISTINGUISHING RWY 30L AND RWY 3 INTXN. IT APPEARED TO ME THAT HOLD SHORT LINE WAS POSITIONED FARTHER FROM RWY THAN USUAL HOLD SHORT LINES ON TXWYS RELATIVE TO RWY. THIS ALSO MAY NOT BE THE CASE DUE TO DIVIDING ATTN BTWN TAXI RTE AND COCKPIT DUTIES. NEXT TIME IN SAT WILL MAKE MENTAL NOTE OF HOLD SHORT LINE.
