Narrative:
Right main landing gear would not come down. The right gear indicator light did not show green and the in-transit light showed red. I declared an emergency; requested the fire truck; and gave persons on board and 300 pounds fuel information to tower. Right landing gear uplock did not release--possible a right gear actuator problem. Control tower verified the right gear was not down during a low pass over the runway. The backup emergency gear procedure did not cause the gear to descend. Tower was informed that this would be a wheels up landing. I raised the gear and purposely made a gentle power-on landing without any gear down. The plane came to a stop pointing down the runway within 10 ft of centerline.human performance considerations: I noticed the gear sound; in-transit red light; and lack of the third green gear indicator light indicating the problem to me. Emergency gear lowering practice and unsafe gear light problems during over a thousand hours of retractable gear flying reduced stress this time. Using the aircraft handbook emergency procedure reduced forgetting a step. I considered the risk of landing with two gears down perhaps causing a ground loop to the right when the wing would descend with the risk that the plane might exit the runway and turn over. Power was kept on to help insure a gentle landing even though I knew that the propeller would be damaged and the engine would have to be inspected. I was so concerned about exiting the plane quickly that I forgot to pull the mixture control to off when the engine stopped. I did switch the master switch and avionics rocker switches off.

Title: A Beech Sierra 200 right landing gear would not extend so all gear were retracted and a gear up landing completed after following all emergency procedures.
