Aircraft; Human Factors; Procedure
It was a routine departure with a left turn to 270 degrees; and a climb to 5;000 FT. Once we made 5;000 FT; I went to cruise mode of flight. We did some climbing turns; and descents. We also checked the autopilot. I then performed the in-range flow to start slowing the airplane down. Our goal here was to operate the aircraft with gear down; and flaps to various degrees to check for controllability; and monitor systems. As I brought the gear handle down; I waited for the standard three green lights. This time; however; all we saw was the nose gear light; the left main light; and the red gear unlocked light switch. The annunciator panel was also showing the hydraulic pressure light. I pushed the test button to see if it was a light bulb. It was not a defective bulb. The light shone brightly once pushing the test button. I cycled the gear to relieve the pressure. The results were exactly the same. I tried cycling the gear two more times; hoping the right gear uplock switch would allow the gear to swing free. It did not so I consulted the QRH for the Emergency Gear Extension Checklist. I put the gear handle down; pulled the hydraulic circuit breaker; and pulled the T-handle to blow down the landing gear. The results were exactly the same; two greens; and one red. I called Approach to ask for vectors for a low approach to see if the Tower could verify the problem of only having two down and locked landing gear. Approach referred me to another airport nearby. Approach vectored me for a left downwind; and switched me to Tower. I completed the low approach; and Tower confirmed the right main gear was not down and locked. We stayed in the pattern at the airport to burn some fuel; and I was talking with Maintenance Control. Maintenance Control advised to try cycling the gear one last time. I did; but our situation was not any different. At this point; I had one hour left of fuel. I declared an emergency with Approach. Approach gave me vectors and I asked to roll emergency equipment so those services would be available once we made the runway. At the point I knew I would land on the runway; I shut down the right engine; and feathered the propeller. About 200 FT off the ground; I shut down the left engine; and also feathered the propeller. I did not use landing lights; and only 10 degrees of flaps. Before touchdown; all electrical systems were off; fuel selectors were in the off position; and the crossfeed was closed. I landed on the left main; and kept control inputs in for as long as possible to keep the airplane balanced on the left main gear. Once the energy dissipated; the right wing started to slowly dip. It eventually began sliding on the runway causing the plane to veer to the right. I applied the brakes; and we came to rest on the right side of the runway. We exited the airplane quickly; and we were met with the airport fire trucks who gave us assistance.
C402 Captain reports discovering during a post maintenance test flight that the right landing gear will not extend. All attempts to get the right gear to extend are unsuccessful and a partial gear up landing ensues.
