Primary finding
Probable cause
The pilot's failure to follow the checklist. A factor relating to this accident was the misadjustment of the landing gear locking mechanism which caused intermittent operation.
Investigator assessment
Analysis narrative
The airplane landed with the right main landing gear in the retracted position. The pilot failed to ascertain that all of the landing gears were fully extended before attempting the landing. Inspection of the landing gear system disclosed that the landing gear uplock was not properly adjusted and that the right main landing gear would intermittently fail to extend. The CESSNA service manual reveals that the landing gear light will not illuminate unless all landing gears are in the extended and locked position.
