EXAMINATION OF THE RIGHT MAIN LANDING GEAR REVEALED THAT THE BOLT THAT ATTACHES THE RIGHT HAND BELLCRANK TO THE LANDING GEAR STRUT WAS SHEARED IN TWO PLACES. THE BOLT SHEARED ON EITHER SIDE OF THE BELLCRANK AT THE POINT BETWEEN THE BELLCRANK AND THE STRUT CASTING. A SOLID PIN JOINS THE BELLCRANK TO THE SIDE BRACE LOCK LINK. THE LOCK LINK FITS BETWEEN THE TWO EARS OF THE BELLCRANK. ## Factual narrative On July 5, 1994, at 1203 hours Pacific daylight time, a Cessna 310J, N310BD, lost control and veered off runway 23 after the right main landing gear collapsed at the Elko Municipal Airport, Elko, Nevada. The airplane was being operated by Copper State Air Service, Inc., Mesa, Arizona, as an on-demand air cargo flight under 14 CFR Part 135. The airplane sustained substantial damage. The certificated airline transport pilot was not injured. The flight originated in Lovelock, Nevada. Visual meteorological conditions prevailed at the time and a company VFR flight plan was filed. The automated weather observation station at the Elko Municipal Airport was reporting the winds from 250 degrees at 25 knots gusting to 31 knots about 10 minutes before the accident. Examination of the right main landing gear by an inspector from the Federal Aviation Administration (FAA) revealed that the bolt that attaches the right hand bellcrank to the landing gear strut was sheared in two places. The bolt sheared on either side of the bellcrank at the point between the bellcrank and the strut casting. A solid pin joins the bellcrank to the side brace lock link. The lock link fits between the two ears of the bellcrank. The pin appeared to be intact and looked as if it hadn't been removed for several years, or at least since that portion of the airplane was last painted. ## Aircraft - Registration: [N310BD](https://openairdocs.org/aircraft/N310BD), registered now, S/N 310J0013, built 1965 (OpenAirDocs) - Reported make and model: CESSNA 310J - Registry model: [Cessna 310J](https://openairdocs.org/model/cessna-310j) (registry code 2074226) (OpenAirDocs) - Registry engine: [Continental I0-470 series](https://openairdocs.org/engine/continental-i0-470-series) (registry code 17027, reciprocating) (OpenAirDocs) - Category: Airplane - Serial number: 310J013 - Airframe hours: 3854 - Engines: CONTINENTAL IO-470U 260 horsepower reciprocating - Damage: Substantial damage - Flight: Part 135 - Operator: Copper State Air Service, Inc. - Registered owner: W.

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.
