The airframe and powerplant mechanic's incorrect reassembly of the landing gear.
Findings · 2
NTSB’s coded findings. Those marked are part of the probable cause; the rest are factors or other findings. Under each, the cases with the same finding.
Sequence of events
The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.
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.
