Cessna 401, N401JN
Following an uneventful flight, and during the rollout, the right main landing gear (MLG) collapsed. Subsequent investigation revealed a fatigue failure and overload of the arm attachment holes on the right MLG torque tube and the crack appeared to have been growing since around 2001. A Supplementary Inspection Document (SID) issued by Cessna in 2004 recommended inspections of the arm attachment holes of the torque tube but the inspection had not been carried out N401JN. This SID is mandatory on aircraft registered in Europe used for commercial air transport, and from September 2008 for those used privately. The SID is not mandatory for US registered aircraft, such as N401JN. One Safety Recommendation has been made.
