After pushback we were given clearance by BOI Ground Control to taxi to Runway 10L via Taxiway A and then Taxiway W. As we taxied out we did not receive the final weight manifest from Load Planning in the normal time frame so we performed the before takeoff checklist 'down to' the Manifest Changes line. As we continued to wait for the final weights from load planning we began approaching the intersection of Taxiway A and Taxiway W. As we approached the above intersection I went 'heads down' to switch the aircraft radio to Tower frequency and to enter the 'address' for Load Planning into ACARS in regards to not receiving the final weights. After performing the two above tasks; I looked up and noticed that we were passing over the hold short line to Runway 10L at Taxiway A and Taxiway J. We traveled a short distance past the line and then the Captain stopped the airplane. We then advised BOI Tower that we had passed the hold short line for Runway 10L.
The A320 stopped well past the hold line. As a result a Cessna on approach was sent around to avoid landing over the top of the Airbus. I was CIC and noticed the event simultaneously with the Controller who was being relieved at the time and prompted the assuming Controller at Local Control to send the Cessna around.
When an A320 flight crew was distracted by receiving their final weight and balance numbers from their company they inadvertently crossed the hold short line of the runway to which they had been cleared. ATC directed a Cessna on final approach to go around due to the incursion.
