Accident Overview
On November 25, 2011, at approximately 0900 mountain standard time, a Cessna 310I (registration N8059M) experienced a landing gear collapse during the landing roll at Sedona, Arizona. The airplane sustained substantial damage. The airline transport pilot and three passengers were not injured.
Flight Details
The pilot, who was also the owner, operated the flight under 14 Code of Federal Regulations Part 91. Visual meteorological conditions prevailed for the personal cross-country flight, which originated from Chandler, Arizona, about 40 minutes prior. No flight plan was filed.
Pilot Account
The pilot reported an uneventful flight. He entered the traffic pattern for landing and completed the landing checklist, including lowering the flaps and landing gear. No anomalies were noted until the right main landing gear collapsed during the landing roll. Subsequently, the nose and left main landing gears collapsed, and the airplane came to rest on its belly. The fuselage structure forward of the cockpit was bent and wrinkled.
Post-Accident Examination
A Federal Aviation Administration (FAA) inspector observed and photographed the accident site and recovery. Photos showed ground scars consistent with the right propeller striking the runway, followed by a continuous scrape mark and tire marks from the nose and left main landing gears. The left main inboard gear door appeared closed; the right main inboard gear door was partially open with the outboard portion folded back. The left and right main gear side braces were both in an unlocked and partially retracted position.
The left main gear was separated from its wing attachment pivot points, and the left main gear wheel was separated from the gear leg. No broken or disconnected parts were visible in the left main gear retraction/extension system. The right main landing gear sustained relatively little damage, remaining intact; except for the control rod for the right main inboard gear door, no broken or disconnected parts were observed. That control rod was bent and separated with a shiny fracture surface consistent with overload failure. The nose landing gear was folded back and to the right. The extent of impact damage to the landing gear precluded a functional extension/retraction test.
Manufacturer Information
According to a representative of the airplane's manufacturer, the inboard main landing gear doors are closed when the landing gear is in both the up and down positions. The doors are only open during gear transition.
