NTSB narrative

The pilot of the Canadian registered Cessna 340 reported that he touched down on runway 20 and as the aircraft was settling on the main gear the right wheel began to collapse. The pilot reported winds at the time of landing as 10 degrees right of the nose at 13 knots gusting to 17-18 knots; and an observation taken 16 minutes before the accident reported winds of 210 degrees magnetic at 14 knots. Although there were six occupants aboard the total weight of the aircraft was not known at touchdown. A post crash visual examination of the fracture surfaces of the right main landing gear bellcrank assembly (upper end), the adjustable end fitting (side brace lock), and the bellcrank clevis ears revealed separation surfaces that were grainy, 45 degree or cup and cone in nature, and which were without fatigue striations consistent with overload.

Probable cause

The overload of the right main landing gear bellcrank, adjustable end fitting and clevis ears resulting in fractures and the subsequent gear collapse.

  • Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
  • Filled from the NTSB case API where the bulk record had no value: investigation status, coordinates. Values present in the bulk record are kept.
  • The date is the local date, which is the same as the UTC date the NTSB stores.
