He performed a go-around, climbed to altitude, and attempted emergency procedures and g loading maneuvers but was unable to extend the right main landing gear into the down and locked position. Ultimately, the pilot chose to land with the landing gear retracted. During recovery of the airplane from the runway, maintenance personnel were unable to extend and lock the right main landing gear, but they were able to extend and lock the nose and left main landing gears into position. The right main landing gear was manually extended and braced, then towed to the ramp. The pilot/operator of the aircraft reported that the damage to the aircraft was substantial. A complete examination of the right main landing gear was not performed; therefore, the reason for the right main landing gear anomaly could not be determined. ## Factual narrative On August 21, 2019, about 1235 eastern daylight time, a Cessna 310L, N2299F, was substantially damaged when it was involved in an accident near Tampa, Florida. The commercial pilot was not injured. The airplane was operated as a Title 14 Code of Federal Regulations Part 91 personal flight. The pilot stated that, while on landing approach, the right main landing gear would not indicate down and locked. He "wiggled" the light for the right main landing gear and changed the light bulb, but the right main landing gear did not indicate down and locked. He continued the approach and landed, but during the landing roll, the right main landing gear began to collapse. He aborted the landing and climbed to altitude, where he cycled the landing gear and tried to extend the right main landing gear using the emergency gear extension procedure multiple times. He also attempted abrupt maneuvers but was unable to get the right main landing gear down and locked. He then attempted a second landing, with the same results. After the aborted second landing, he contacted air traffic control, declared an emergency, and diverted to a tower-controlled airport. He performed one low pass and one fly-by of the air traffic control tower and was told that the right main landing gear appeared to be down. He returned for landing and, during landing, again felt the right main landing gear was collapsing. He aborted the landing then informed the tower controller that he would land gear-up. He subsequently performed a gear-up landing. The pilot/operator subsequently reported that the damage to the aircraft was substantial. During recovery of the airplane, airport maintenance personnel were unable to lock the right main landing gear using the emergency gear extension system but were able to manually push the gear over-center and brace it. They also secured the nose and left main landing gear over-center with heavy tie wraps and towed the airplane to the ramp. The airplane was examined by a Federal Aviation Administration (FAA) airworthiness inspector following recovery. The inspector reported that he could not determine the reason the right main landing gear would not go into the down and locked position; however, no disassembly was performed to gain access to all components of the right main landing gear retraction and extension system. ## Aircraft - Registration: [N2299F](https://openairdocs.org/deregistered/N2299F-2023-02-04), registration cancelled 2023-02-04, S/N 310L-0099, built 1967 (OpenAirDocs) - Reported make and model: Cessna 310 (L) - Registry model: [Cessna 310L](https://openairdocs.org/model/cessna-310l) (registry code 2074230) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 310L-0099 - Year built: 1967 - Airframe hours: 2486.3 - Engines: Continental IO-470-V 260 horsepower reciprocating; Continental IO-470-V 260 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Airworthiness certificate: Standard, Normal - Last inspection: Annual, November 15, 2018, 4 hours before - Departed: PXE, Perry, GA - Destination: TPA, Tampa, FL - Airport: TPA, Tampa International Airport, runway 19L, 8,300 × 150 ft, concrete - Equipment: Onboard weather, Stall warning system, Electronic flight bag or handheld device, Electronic multifunction display, Electronic primary flight display ## Flight crew As NTSB recorded them.

Aircraft are matched to registry aircraft by N-number and event date, checked against the reported serial number, make and model; the registry's history has gaps, so older matches can be wrong.
