The airplane came to rest off the left side of the runway. Inspection of the airplane revealed the left main and nose gears were retracted. Post accident testing of the landing gear failed to reveal any failure/malfunction of the gear system. ## Factual narrative On March 15, 1997, at 1328 central standard time, a Cessna T210, N6677N, operated by a private pilot experienced a left main landing gear collapse during takeoff roll at Rock County Airport, Janesville, Wisconsin. The personal 14 CFR Part 91 flight was operating in visual meteorological conditions without a flight plan. The airplane was substantially damaged and the pilot was not injured. The pilot reported that during the takeoff roll on runway 31 (5,396' x 150') the left main gear collapsed at an airspeed of 60 to 70 knots. According to the mechanic who retrieved the airplane after the accident, the airplane veered about 20 feet off the left side of the runway coming to rest approximately 2,000 feet down the runway near the intersection of runway 31/13 and 04/22. Inspection of the airplane by an A&P/IA mechanic from Terry's Aero, Inc., who removed the airplane revealed the outboard leading edge of the left wing was crushed back 5 to 6 inches, the propeller was damaged, the nose gear doors were bent, the bottom of the fuselage sustained skin damage and the lower left portion of the firewall was damaged. He stated the nose gear was pushed up in the wheel well and the left main gear was pushed up. The landing gear selector handle was in the down position. He stated that when the airplane was lifted off the runway the left main gear and the nose gear were easily extended. The landing gear was cycled by this mechanic under the supervision of a Federal Aviation Airworthiness Inspector from the Milwaukee Flight Standards District Office. The landing gear operated normally during the functional tests. ## Aircraft - Registration: [N6677N](https://openairdocs.org/deregistered/N6677N-2013-01-14), registration cancelled 2013-01-14, S/N 21063143, built 1978 (OpenAirDocs) - Reported make and model: Cessna T210 - Registry model: [Cessna T210N](https://openairdocs.org/model/cessna-t210n) (registry code 2073456) (OpenAirDocs) - Registry engine: [Continental TSIO-520 series](https://openairdocs.org/engine/continental-tsio-520-series) (registry code 17040, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 21063143 - Engines: Continental TSIO-520-R 310 horsepower reciprocating - Damage: Substantial damage - Flight: Personal, Part 91 - Registered owner: Tod O.

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.
