NTSB Factual Report

On June 1, 2018, about 1118 Pacific daylight time, a retractable landing gear-equipped Cessna 210 airplane, N9410M, sustained substantial damage after a main landing gear collapsed during a landing at Ramona Airport (RNM), Ramona, California. The private pilot and passenger were uninjured. The airplane was registered to a private individual and operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91 as a visual flight rules personal flight. Visual meteorological conditions prevailed, and no flight plan was filed. The flight departed Alexander Municipal Airport (E80), Belen, New Mexico, about 0830 mountain daylight time.

During an interview with the National Transportation Safety Board (NTSB) investigator-in-charge, the pilot stated that while approaching RNM, he selected the landing gear handle to the down position; however, the green gear down light did not illuminate and the main landing gear did not lock in the down position. He then selected the landing gear handle up and the landing gear did not retract. He maneuvered to the north of the airport and attempted to manually pump the landing gear down with the emergency hand pump. The pilot stated that the handle was very difficult to move and after several pumps it would not move at all. He utilized an airframe mounted mirror to visually check that the left landing gear was in the down position, and then conducted a visual approach and landing to runway 27.

During the landing, the right main landing gear collapsed and the airplane veered to the right and departed the runway surface, coming to rest on the parallel taxiway. During the accident sequence, the right wing and horizontal stabilizer impacted the ground, resulting in substantial damage to the right horizontal stabilizer and elevator.

The airplane was removed from the runway and secured for further investigation.
