Aviation Accident Summary DFW08CA099

Roswell, NM, USA

Aircraft #1

N7935Q

Cessna 310Q

Analysis

The pilot initiated a left turn while taxiing to the parking area, and the right main landing gear collapsed, resulting in substantial damage to the airplane's right wing and horizontal stabilizer. A Federal Aviation Administration (FAA) inspector did an on scene investigation, and determined that the landing gear was not properly reassembled after maintenance was performed. The certified airframe and powerplant mechanic left out a bushing on the right main landing gear side link lower attach point. The incorrect reassembly allowed the down-lock tension to fall below allowable limits during subsequent cycles of the landing gear system, resulting in the gear collapse.
