Aircraft damage: Unknown
Category:Incident
Location:Brisbane Airport (YBBN), Brisbane, QLD -   Australia
Phase: Taxi
Nature:Domestic Scheduled Passenger
Departure airport:Brisbane International Airport, QLD (BNE/YBBN)
Destination airport:Melbourne-Tullamarine Airport, VIC (MEL/YMML)
Investigating agency: ATSB
Narrative:
Whilst taxiing in preparation for departure from Brisbane Airport, the aircraft experienced a landing gear failure in which the outboard wheel hub separated from the left-hand landing gear. The aircraft was subsequently unable to be towed back to the terminal.

Contributing factors:
A majority of the wheel's tie bolt assemblies loosened while in service, likely due to grease or anti-seize compound between the mating wheel halves. This resulted in fatigue cracking and ultimately, wheel rupture.
The tie bolt assemblies on this wheel-type (single-web) were more prone than dual-web wheels to loosening during service, however there were no inspections for detecting loose tie bolt assemblies in service and no effective mandated risk controls to prevent wheel rupture.
