Analysis

During landing roll at the Lincoln airport, the outboard wheel of the left main landing gear separated from the axle. The acft was not hampered in its landing roll and taxithe landing gear assembly revealed that a retaining nut washer was not installed on this assembly. This allowed the wheel to shift sidewards and subsequently fall free from the axle. Maintenace records showed that this wheel had been changed 10 days prior to this flight.
