Narrative:

Taxi clearance 'taxi to runway 3, hold short of ILS critical area.' during long taxi in snow, dusk and reduced visibility, we taxied past the ILS hold line. There was an aircraft in front of us that had done the same thing. Ground control advised us of our mistake. Contributing factors included: 1) crew was distraction by an intermittent bleed air warning annunciator light, 2) this caused us to be late in completing our before takeoff checklist, and 3) snow covered the ILS hold line. Lesson learned: whether in the air or on the ground, the #1 priority is to control the aircraft. Do not become distraction and bust a ground clearance. Supplemental information from acn 535259: ground covered with 1 inch snow, WX, snowing 3/4 mi visibility, 400 ft ceiling. An annunciator indication/diagnosis had delayed our pre takeoff check during taxi. We were cleared to the ILS hold at runway 3. We followed another aircraft beyond the ILS hold position, as we finished our items. While we were extra careful with taxi due to the WX, neither of us saw the hold short sign! We are both embarrassed that we followed the leader past our clearance limit. I do not know if the sign was lighted or not, but it did not get our attention if it was. ATC did not catch our mistake for about 1/2 min after we were holding short behind the leading plane.

Title: A KING AIR B200 FLC CROSSES THE ILS HOLD SHORT LINE DURING A SNOW STORM.

Narrative: TAXI CLRNC 'TAXI TO RWY 3, HOLD SHORT OF ILS CRITICAL AREA.' DURING LONG TAXI IN SNOW, DUSK AND REDUCED VISIBILITY, WE TAXIED PAST THE ILS HOLD LINE. THERE WAS AN ACFT IN FRONT OF US THAT HAD DONE THE SAME THING. GND CTL ADVISED US OF OUR MISTAKE. CONTRIBUTING FACTORS INCLUDED: 1) CREW WAS DISTR BY AN INTERMITTENT BLEED AIR WARNING ANNUNCIATOR LIGHT, 2) THIS CAUSED US TO BE LATE IN COMPLETING OUR BEFORE TKOF CHKLIST, AND 3) SNOW COVERED THE ILS HOLD LINE. LESSON LEARNED: WHETHER IN THE AIR OR ON THE GND, THE #1 PRIORITY IS TO CTL THE ACFT. DO NOT BECOME DISTR AND BUST A GND CLRNC. SUPPLEMENTAL INFO FROM ACN 535259: GND COVERED WITH 1 INCH SNOW, WX, SNOWING 3/4 MI VISIBILITY, 400 FT CEILING. AN ANNUNCIATOR INDICATION/DIAGNOSIS HAD DELAYED OUR PRE TKOF CHK DURING TAXI. WE WERE CLRED TO THE ILS HOLD AT RWY 3. WE FOLLOWED ANOTHER ACFT BEYOND THE ILS HOLD POS, AS WE FINISHED OUR ITEMS. WHILE WE WERE EXTRA CAREFUL WITH TAXI DUE TO THE WX, NEITHER OF US SAW THE HOLD SHORT SIGN! WE ARE BOTH EMBARRASSED THAT WE FOLLOWED THE LEADER PAST OUR CLRNC LIMIT. I DO NOT KNOW IF THE SIGN WAS LIGHTED OR NOT, BUT IT DID NOT GET OUR ATTN IF IT WAS. ATC DID NOT CATCH OUR MISTAKE FOR ABOUT 1/2 MIN AFTER WE WERE HOLDING SHORT BEHIND THE LEADING PLANE.
