F100 FLC HAS RWY INCURSION AT LGA.

Narrative

FROM LOCATION X; RECEIVED A CLRNC FROM GND TO TAXI TO RWY 13 VIA TXWY G; THEN TXWY F; HOLD SHORT RWY 22. IN MAKING THE TURN ONTO TXWY F; WHILE HELPING A NEW COPLT FIX/ENTER TPS DATA INTO THE FMS; I TAXIED BEYOND THE HOLD SHORT LINE. I ASSUMED THE HOLD SHORT LINE WOULD BE AT RWY 22. TXWY F FROM LOCATION X IS A REVERSE HIGH SPD TXWY OFF OF RWY 22. BEING UNFAMILIAR WITH LGA; I DID NOT KNOW OR SEE THAT THE HOLD SHORT FOR RWY 22 ON TXWY F IS LOCATED AFTER THE TURN. AFTER REALIZING I HAD PASSED THE LINE; I STOPPED THE ACFT WELL BEFORE RWY 22. THEN I NOTICED AN ACFT HAD GONE AROUND. GND CALLED AND SAID; 'ACR X NEXT TIME LET US KNOW YOU'RE GOING TO DO THAT.' THEN GAVE US A CLRNC TO CROSS RWY 22 AND TAXI TO RWY 13; THEN ADVISED US TO CALL GND AT ARR. I TALKED TO THE GND SUPVR AND HE SAID HE WOULD LISTEN TO THE TAPE AND FOR ME TO CALL HIM IN THE MORNING. I TALKED TO THE SUPVR AGAIN AND HE INFORMED ME THAT HE FILED A RWY INCURSION AT THE LOWEST LEVEL; NO LOSS OF SEPARATION WITH FLT STANDARDS. I WILL BE MORE VIGILANT WHILE TAXIING AT ARPTS.
