Aircraft Accident/Incident Report
Lakeview, Oregon 97630
Monday, July 7, 2003 17:35 PDT
NTSB Narrative Summary Released at Completion of Accident
The airline transport pilot reported that the airplane's left main landing gear assembly collapsed while taxiing the airplane from the ramp to the active runway. Postaccident examination of the landing gear assembly revealed that the roll pin (part number NAS 561P4) that retains the attaching shaft (part number 0841011-1) to the trunnion assembly was fractured. This allowed the landing gear attaching shaft to shift from its installed position, resulting in the trunnion assembly separating from the landing gear support structure. Following the inspection of the failed landing gear, the operator inspected the landing gear of its remaining Cessna 402's, six in total. Subsequent to the inspections, the operator reported that they identified two aircraft with broken landing gear shaft roll pins. The roll pins were replaced, and the operator reported that the landing gear assemblies would be reexamined in six-month intervals.
NTSB Probable Cause Narrative
Failure of the landing gear shaft roll pin resulting in a main gear collapse during the taxi phase of operation.
