Narrative:

I was landing at oma when the landing gear failed to extend. After flying by the tower, they confirmed that it was not down. I circled east of the field for approximately 30-40 mins. I also contacted my company to advise dispatch of the situation. After several unsuccessful attempts at lowering the gear manually, I was able to get the pump to work and lowered the gear manually. After getting 3 green lights and no warning horn, I flew by the tower for a second time. They confirmed it was down and I proceeded to land without incident. ATC did an excellent job in assisting me. Also, taking my time in assessing the situation helped, as did talking to people on the ground. Being more familiar with the manual extension procedures would have helped. Callback conversation with reporter revealed the following information: reporter stated the failure of the normal mode landing gear extension was a broken right main gear door actuator bracket which jammed the gear causing the gear drive motor circuit breaker to pop. The reporter said this circuit breaker is not accessible from the cockpit so the gear was pumped down manually. The reporter said extra time was taken to remember the manual extend procedures.
