Analysis

During the approach, the right main landing gear would not extend by normal or emergency means. Airplane was intentionally landed with all landing gear retracted. Inspection indicated gear doors pulled closed farther than normal due to right main landing gear roller being stuck below the roller follower arm. Gears doors were stuck closed which in turn effectively locked gear inside gear doors.
