Narrative:

After given taxi instructions from the gate to the departure runway at bwi, I confirmed the taxi route with the captain. At that point the captain called for the taxi checklist. While I was performing the checklist we made a wrong turn on the taxiway and the nose of the aircraft was accidentally taxied across the hold short line of a runway. The aircraft was immediately stopped, with the nose protruding across the hold short line. Corrective instructions from ground control were given and immediately followed. No aircraft conflicts occurred. There were many contributing factors to the event. First, we were working the last leg of a continuous duty trip with a limited amount of rest in a hotel. Second, the fact that we were running checklists during aircraft movement also contributed. Third, baltimore, md, just had a severe snow storm and the runway and taxiway signs were obstructed with snow and ice. To prevent all occurrences such as this one, many factors must be considered. I feel that crew fatigue, checklist usage during aircraft movement, and airport markings and signs are good places to start.

Title: CL65 TAXIING FOR DEP AT BWI CROSSED RWY HOLD LINE.

Narrative: AFTER GIVEN TAXI INSTRUCTIONS FROM THE GATE TO THE DEP RWY AT BWI, I CONFIRMED THE TAXI RTE WITH THE CAPT. AT THAT POINT THE CAPT CALLED FOR THE TAXI CHKLIST. WHILE I WAS PERFORMING THE CHKLIST WE MADE A WRONG TURN ON THE TXWY AND THE NOSE OF THE ACFT WAS ACCIDENTALLY TAXIED ACROSS THE HOLD SHORT LINE OF A RWY. THE ACFT WAS IMMEDIATELY STOPPED, WITH THE NOSE PROTRUDING ACROSS THE HOLD SHORT LINE. CORRECTIVE INSTRUCTIONS FROM GND CTL WERE GIVEN AND IMMEDIATELY FOLLOWED. NO ACFT CONFLICTS OCCURRED. THERE WERE MANY CONTRIBUTING FACTORS TO THE EVENT. FIRST, WE WERE WORKING THE LAST LEG OF A CONTINUOUS DUTY TRIP WITH A LIMITED AMOUNT OF REST IN A HOTEL. SECOND, THE FACT THAT WE WERE RUNNING CHKLISTS DURING ACFT MOVEMENT ALSO CONTRIBUTED. THIRD, BALTIMORE, MD, JUST HAD A SEVERE SNOW STORM AND THE RWY AND TXWY SIGNS WERE OBSTRUCTED WITH SNOW AND ICE. TO PREVENT ALL OCCURRENCES SUCH AS THIS ONE, MANY FACTORS MUST BE CONSIDERED. I FEEL THAT CREW FATIGUE, CHKLIST USAGE DURING ACFT MOVEMENT, AND ARPT MARKINGS AND SIGNS ARE GOOD PLACES TO START.
