Narrative:

During an armed water takeoff, it was discovered only 1 pump was operating, when both pumps are supposed to be operating. At that time the takeoff was aborted. The pump was MEL'ed and the flight was completed. This was the first time I ever had a problem arise in both a crew environment and during a takeoff roll. I, being the captain, hesitated a second or two because I didn't believe it was happening. Once the abort was initiated, it was carried out in a professional manner using both crew members. Cockpit resource management training that we received really did work!

Narrative: DURING AN ARMED WATER TKOF, IT WAS DISCOVERED ONLY 1 PUMP WAS OPERATING, WHEN BOTH PUMPS ARE SUPPOSED TO BE OPERATING. AT THAT TIME THE TKOF WAS ABORTED. THE PUMP WAS MEL'ED AND THE FLT WAS COMPLETED. THIS WAS THE FIRST TIME I EVER HAD A PROB ARISE IN BOTH A CREW ENVIRONMENT AND DURING A TKOF ROLL. I, BEING THE CAPT, HESITATED A SECOND OR TWO BECAUSE I DIDN'T BELIEVE IT WAS HAPPENING. ONCE THE ABORT WAS INITIATED, IT WAS CARRIED OUT IN A PROFESSIONAL MANNER USING BOTH CREW MEMBERS. COCKPIT RESOURCE MGMNT TRAINING THAT WE RECEIVED REALLY DID WORK!
