TKOF FROM GREEN BAY DURING WINTER OPS IS MADE WITH GEAR PIN INSTALLED.

Narrative

AFTER A REDUCED REST OVERNIGHT; WE DEPARTED GRB WITH THE NOSE GEAR PIN INSTALLED. THE NOSE GEAR FAILED TO RETRACT AND WE RETURNED TO THE ARPT WITHOUT INCIDENT. AS THIS WAS A REDUCED REST OVERNIGHT; ALL OF THE FLC AND AT LEAST PART OF THE GND CREW WERE OPERATING UNDER CONDITIONS OF SLEEP DEPRAVATION. THE TUG DRIVER WHO WAS SUPPOSED TO PUSH US BACK HAD BEEN ON DUTY THE NIGHT BEFORE WHEN WE ARRIVED AT GRB. DUE TO THE STRESS OF THE REDUCED REST; I SLEPT ABOUT 4 HRS. WHEN WE ARRIVED AT THE ARPT; THE TWR WAS CLOSED AND WE NEEDED TO DEICE. IMMEDIATELY AFTER PUSHBACK; OUR PROC (BUT NOT OUR CHKLIST); REQUIRES US TO SEE THE GEAR PIN AFTER REMOVAL. IMMEDIATELY AFTER PUSHBACK; I WAS DISTR BY THE DEICE TRUCK MOVING TOWARD THE ACFT. THE DEICE CREW STARTED TO SPRAY THE ACFT WITHOUT GIVING US A START TIME. AS IT WAS IMPORTANT TO GET THIS START TIME; I CONTINUED TO WATCH THE DEICE TRUCK AND NEVER RETURNED MY ATTN TO THE GEAR PIN. THE FO WAS DISTR BY COM WITH THE NEWLY OPENED TWR AND WAS GETTING THE ATIS AND CLRNC. THIS REQUIRED US TO GO BACK AND REREAD THE APPROPRIATE CHKLISTS PRIOR TO TAXI. CORRECTIVE ACTION: PUT 'NOSE GEAR PIN -- REMOVED' ON THE CHKLIST.
