On final the First Officer called for GEAR DOWN; LANDING CHECKS; PROPELLERS FULL FORWARD when bring the gear down we realized nothing had happened. When looking at the gear we noticed that the landing gear circuit breaker had popped. We decided to go around since at this point our gear was not down. I referenced the Abnormal Checklist for Circuit Breaker Tripped realized it wasn't essential then went to the Abnormal Checklist for Failure of the Landing Gear to Extend Normally. At this time I had notified company through operations and told them to get a hold of Maintenance Control. We ran through the checklist and found out that the gear was not down and locked. Part of this checklist is to contact Maintenance Control and discuss the situation which would be to bring the gear down manually. At this time we also declared an emergency with ATC. We continued to get vectored around the area. I then ran the Abnormal Checklist for Landing Gear Manual Extension Checklists in which I brought the gear down manually and the final indications were down three green with no in-transit indications. That checklist also refers to us calling Dispatch and Maintenance Control to discuss any further actions. They told us to continue to land. They also asked if we could taxi the airplane off the runway and I told them that the checklist says that the gear is to be considered unsafe and that I would be stopping on the runway. When talking to approach we requested the long runway and briefed. At this time we are headed back and ran the Quick Return Checklist and Approach Checklists. After this was done I took the controls and made the approach and landing. We landed with no problems. I brought it to a stop and shut down the engines with fire and rescue at the plane. Maintenance came and put the gear pins in the landing gear then we decided to deboard the passengers to the van which was waiting. Once the passengers were off the Mechanic and I taxied the airplane back to the ramp. The Mechanic felt since there was gear pins in that the taxi would be better than towing it. Running the checklists for the abnormalities in the gear take a long time. When the circuit breaker popped I knew that my gear was not down and locked. So I think that there should be an Abnormal Checklist for Landing Gear Circuit Breaker Tripped. Then it should refer you to the Abnormal Checklist for Landing Gear Manual Extension. These checklists take a while to run and more than likely they happen during approach as we continue to burn more fuel. In some cases these people might not have enough fuel for the time some of these checklists take to run. For the problem I had; I knew me gear was not down and locked so I feel like I was wasting my gas on running the Abnormal Checklist for Failure of the landing gear to extend normally.
BE1900 Captain reports failure of the landing gear to extend during approach and notes the landing gear control circuit breaker is tripped. Checklists are consulted and eventually the manual gear extension checklist is employed successfully and an uneventful landing ensues.
