Narrative:

Location: hold short runway 17R den. I was the captain on this S80 flight. While awaiting takeoff on runway 17R in den, I noticed some possible smoke coming from the right main gear truck of a departing B777. I asked tower to alert the B777 and have him check his brake temperatures, as I suspected a dragging brake. I obviously got too preoccupied watching and listening for the call to the B777, and the first officer alertly observed I was drifting across the hold short. The first officer asked if we were cleared into position and hold. I said we were not and reset the parking brake. (The first officer also confirmed we were not cleared with tower.) after I stopped, the nose of the aircraft appeared to be over the hold short line by about 2 ft. (A B737 departed runway 17R after the B777.) there was an arriving propeller aircraft on final for landing after the B737 departed. In my judgement, there was no conflict with the arriving propeller due to my aircraft's nose position, and the propeller subsequently landed. The cause of this event was that I allowed myself to get distraction from my primary responsibility of controling my aircraft. I will be more focused in the future, and more alert to unnecessary distrs of this sort. Thanks to my first officer for his keen situational awareness and quick response.

Narrative: LOCATION: HOLD SHORT RWY 17R DEN. I WAS THE CAPT ON THIS S80 FLT. WHILE AWAITING TKOF ON RWY 17R IN DEN, I NOTICED SOME POSSIBLE SMOKE COMING FROM THE R MAIN GEAR TRUCK OF A DEPARTING B777. I ASKED TWR TO ALERT THE B777 AND HAVE HIM CHK HIS BRAKE TEMPS, AS I SUSPECTED A DRAGGING BRAKE. I OBVIOUSLY GOT TOO PREOCCUPIED WATCHING AND LISTENING FOR THE CALL TO THE B777, AND THE FO ALERTLY OBSERVED I WAS DRIFTING ACROSS THE HOLD SHORT. THE FO ASKED IF WE WERE CLRED INTO POS AND HOLD. I SAID WE WERE NOT AND RESET THE PARKING BRAKE. (THE FO ALSO CONFIRMED WE WERE NOT CLRED WITH TWR.) AFTER I STOPPED, THE NOSE OF THE ACFT APPEARED TO BE OVER THE HOLD SHORT LINE BY ABOUT 2 FT. (A B737 DEPARTED RWY 17R AFTER THE B777.) THERE WAS AN ARRIVING PROP ACFT ON FINAL FOR LNDG AFTER THE B737 DEPARTED. IN MY JUDGEMENT, THERE WAS NO CONFLICT WITH THE ARRIVING PROP DUE TO MY ACFT'S NOSE POS, AND THE PROP SUBSEQUENTLY LANDED. THE CAUSE OF THIS EVENT WAS THAT I ALLOWED MYSELF TO GET DISTR FROM MY PRIMARY RESPONSIBILITY OF CTLING MY ACFT. I WILL BE MORE FOCUSED IN THE FUTURE, AND MORE ALERT TO UNNECESSARY DISTRS OF THIS SORT. THANKS TO MY FO FOR HIS KEEN SITUATIONAL AWARENESS AND QUICK RESPONSE.
