Narrative:

Our airplane had just come in. It was our first leg of the day. I decided to do a battery start since it was already after time XA20Z and we had no power. #2 engine battery start was uneventful. We pushed back and did a cross bleed start on #1. Taxied out to runway. During takeoff roll; I cross checked my airspeed with the standby airspeed indicator. It read zero. First officer was the PF on this leg. I called abort; took control and rejected the takeoff; noting no airspeed on standby airspeed indicator. We had not reached the 100 KT incapacitation check. First officer notified tower and we pulled off the runway; notified flight attendant and passenger and completed after landing checklist. We pulled into a remote area of ramp to troubleshoot problem. Brake temperatures never got above 6; left inboard got to 7. Contacted dispatch/maintenance and advised to return to gate. Deplaned passenger and maintenance arrived. During diagnosis; maintenance found standby pitot system completely full of water. He had to drain system 3 times to get all the water out of the system. Maintenance also inspected tires (fuse plugs) and signed off aircraft for ferry flight.callback conversation with reporter revealed the following information: the reporter stated the day was dry with no visible moisture present and the airplane had just flown in to the station with no inbound reports; just the auxiliary power unit deferred. The takeoff was rejected when it was noted the standby airspeed indicator read '0.' back on the gate; the standby pitot system was drained three times to eliminate all the water. No moisture was found in the primary left and right pitot drains. The reporter suggests the routine checks that would check the pitot static drains for moisture were not accomplished.

Narrative: OUR AIRPLANE HAD JUST COME IN. IT WAS OUR FIRST LEG OF THE DAY. I DECIDED TO DO A BATTERY START SINCE IT WAS ALREADY AFTER TIME XA20Z AND WE HAD NO POWER. #2 ENG BATTERY START WAS UNEVENTFUL. WE PUSHED BACK AND DID A CROSS BLEED START ON #1. TAXIED OUT TO RWY. DURING TKOF ROLL; I CROSS CHKED MY AIRSPD WITH THE STANDBY AIRSPD INDICATOR. IT READ ZERO. FO WAS THE PF ON THIS LEG. I CALLED ABORT; TOOK CTL AND REJECTED THE TKOF; NOTING NO AIRSPD ON STANDBY AIRSPD INDICATOR. WE HAD NOT REACHED THE 100 KT INCAPACITATION CHK. FO NOTIFIED TWR AND WE PULLED OFF THE RWY; NOTIFIED FLT ATTENDANT AND PAX AND COMPLETED AFTER LNDG CHKLIST. WE PULLED INTO A REMOTE AREA OF RAMP TO TROUBLESHOOT PROB. BRAKE TEMPS NEVER GOT ABOVE 6; LEFT INBOARD GOT TO 7. CONTACTED DISPATCH/MAINT AND ADVISED TO RETURN TO GATE. DEPLANED PAX AND MAINT ARRIVED. DURING DIAGNOSIS; MAINT FOUND STANDBY PITOT SYSTEM COMPLETELY FULL OF WATER. HE HAD TO DRAIN SYSTEM 3 TIMES TO GET ALL THE WATER OUT OF THE SYSTEM. MAINT ALSO INSPECTED TIRES (FUSE PLUGS) AND SIGNED OFF ACFT FOR FERRY FLT.CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE DAY WAS DRY WITH NO VISIBLE MOISTURE PRESENT AND THE AIRPLANE HAD JUST FLOWN IN TO THE STATION WITH NO INBOUND RPTS; JUST THE AUXILIARY POWER UNIT DEFERRED. THE TKOF WAS REJECTED WHEN IT WAS NOTED THE STANDBY AIRSPD INDICATOR READ '0.' BACK ON THE GATE; THE STANDBY PITOT SYSTEM WAS DRAINED THREE TIMES TO ELIMINATE ALL THE WATER. NO MOISTURE WAS FOUND IN THE PRIMARY L AND R PITOT DRAINS. THE RPTR SUGGESTS THE ROUTINE CHKS THAT WOULD CHK THE PITOT STATIC DRAINS FOR MOISTURE WERE NOT ACCOMPLISHED.
