Procedure; Human Factors
We ferried the airplane with a hydraulic problem. After about two hours in the maintenance hangar; the airplane was fixed and we took off. During that time in the hangar; mechanics ran some tests and pulled the hydraulic standby pumps circuit breakers and did not push them back. During preflight we did not notice that. After landing I noticed there was no standby hydraulic pressure. I checked the circuit breakers: they were out. I called maintenance. Mechanics did not do their part correctly; we did not do ours. For us it was a long day without any meals.
A DHC8-100 Captain reports accepting an aircraft after maintenance for a hydraulic problem and discovers after landing at destination that the standby hydraulic pump circuit breakers were pulled by maintenance as part of the procedure and never reset.
