main gears partially extended. Post-landing examination revealed right main gear hydraulic actuator had failed due to overstress along metal grain boundaries and at area of low wall thickness. All hydraulic system pressures were found to be normal and no other landing gear system failures were found. After failure of the gear actuator all normal and emergency system fluid was lost through the actuator. Probable cause(s): Failure of the right main landing gear actuator due to overstress for undetermined reasons which resulted in loss of all landing gear system hydraulic fluid which in turn resulted in the pilot being unable to extend and lock the landing gear. October 27, 1994 Jacksonville, FL, Cessna 210L, N732CQ, Injuries: 1 Uninjured: The pilot was on approach at the destination airport and lowered the landing gear. The right main landing gear did not illuminate. The pilot completed the emergency procedure from memory and visually checked the landing gear. The landing gear appeared to be extended. The pilot landed without further incident and taxied to the ramp. Visual inspection of the landing gear revealed the right main landing gear was not in the lock position. The pilot called maintenance personnel on the phone and was informed to reposition the airplane to another airport with the landing gear down to get a replacement airplane. The pilot flew the airplane to the maintenance base. On landing rollout, the right main landing gear collapsed. Examination of the landing gear by the FAA revealed improper rigging of the right main landing gear down lock mechanism due to normal wear. The probable cause was the pilot's decision to depart an airport and continue flight with known deficient equipment. Contributing to the accident was the failure of company maintenance personnel to adjust the down lock mechanism prior to flight. August 21, 1996, KOPF, Cessna 210M, N732ST, injuries: 1 uninjured: – The pilot stated he was in cruise flight at 3,000 feet, when the engine quit. He said that he moved the fuel selector from the left main tank to the right main tank and attempted two engine restarts, which were unsuccessful. A forced landing was made in the Everglades. Visual examination of the left fuel tank revealed no fuel and the fuel cap was tight. Fuel was present in the right fuel tank and the fuel cap was tight. The wings were not damaged and no fuel leaks were observed. Review of
