The pilot stated that he was conducting touch and go landings at an airport when he observed an unsafe landing gear indication after attempting to lower the landing gear. The emergency gear extension checklist was followed and the landing gear would not come down. He diverted to another airport and contacted the control tower. A fly-by was requested and the controller informed the pilot that the nose gear was extended, however the main landing gear was not extended. The pilot entered the traffic pattern and made an emergency landing to the sod area left of runway 04. The landing gear actuator was forwarded to an authorized repair station for further examination. The examination revealed the actuator was in the partially extended position during the gear up landing. The repair station confirmed the hydraulic pump was functioning, and the landing gear actuator was in the partially extended position during the gear up landing. The teardown concluded, "It is our professional opinion, based on non-teardown of the unit that the power pack would have functioned and sequenced as designed; however, there is serious question as to the ability of the main gear actuators to overcome the flight loads if operated at 60 percent (fluctuating between 750 psi and 900 psi) of designed system pressure (required to be at 1950 plus or minus 50 psi.")
Probable Cause: The malfunction of the main hydraulic landing gear system actuator resulting in an emergency gear up landing.
