Crew was repositioning aircraft from a remote parking location to the terminal area. Due to a breakdown in CRM the captain (me) allowed the standard procedures; ie; checklist completion (before start checklist) to be bypassed. While beginning taxi phase to reposition aircraft I attempted to steer aircraft with tiller and nosewheel steering was not responsive. I applied brakes and called for first officer to do so as well. Just as the aircraft rolled off of taxiway onto soft grassy area I noticed that the hydraulic pumps were not in the required position of 'automatic/on.' contributing factors were crew fatigue (early show time; last day of 4-DAY trip); CRM breakdown (ie; captain allowed external ATC radio calls to interfere with cockpit duties); trying to rush to move aircraft to board passenger at the terminal to make an updated 'etdc' window. Note: only flight crew plus 1 flight attendant on board. No passenger. No injuries; no damage to aircraft whatsoever.
Original NASA ASRS Text
Title: CL65 CREW DOES NOT USE BEFORE START CHECKLIST AND ATTEMPTS TO TAXI WITH THE HYDRAULIC PUMPS OFF. STEERING AND BRAKES ARE INOPERATIVE AND THE ACFT GOES OFF THE TAXIWAY.
Narrative: CREW WAS REPOSITIONING ACFT FROM A REMOTE PARKING LOCATION TO THE TERMINAL AREA. DUE TO A BREAKDOWN IN CRM THE CAPT (ME) ALLOWED THE STANDARD PROCS; IE; CHKLIST COMPLETION (BEFORE START CHKLIST) TO BE BYPASSED. WHILE BEGINNING TAXI PHASE TO REPOSITION ACFT I ATTEMPTED TO STEER ACFT WITH TILLER AND NOSEWHEEL STEERING WAS NOT RESPONSIVE. I APPLIED BRAKES AND CALLED FOR FO TO DO SO AS WELL. JUST AS THE ACFT ROLLED OFF OF TXWY ONTO SOFT GRASSY AREA I NOTICED THAT THE HYD PUMPS WERE NOT IN THE REQUIRED POS OF 'AUTO/ON.' CONTRIBUTING FACTORS WERE CREW FATIGUE (EARLY SHOW TIME; LAST DAY OF 4-DAY TRIP); CRM BREAKDOWN (IE; CAPT ALLOWED EXTERNAL ATC RADIO CALLS TO INTERFERE WITH COCKPIT DUTIES); TRYING TO RUSH TO MOVE ACFT TO BOARD PAX AT THE TERMINAL TO MAKE AN UPDATED 'ETDC' WINDOW. NOTE: ONLY FLT CREW PLUS 1 FLT ATTENDANT ON BOARD. NO PAX. NO INJURIES; NO DAMAGE TO ACFT WHATSOEVER.
