Australia's Transportation Safety Board (ATSB) released their final report without a formal conclusion or safety message.
The ATSB reported that a licensed maintenance engineer found the inboard wheel half hub had fractured into a number of pieces, the wheel bearings were intact. Examination showed no indication of bearing cup rotation (a known wheel failure scenario that had been addressed by a service bulletin already). Nonetheless, the origin of the failure was identified in the area of bearing bore radius, from where a series of cracks had grown axially and circumferentially around the inboard hub. The ATSB wrote: "The wheel manufacturer also examined the failure. They concluded it was likely that the fatigue crack initiated in the stress-concentrated, transition region between the bearing bore wall and the circumferential radius. Ultrasonic testing of this area detected possible small fatigue cracks or origins."
The ATSB wrote: "Examination of the maintenance records, from the 15 months before the inboard wheel-half failure, found that the wheel manufacturer’s recommended inspections had been performed whenever the wheel had been removed from the aircraft."
The ATSB reported that the operator took a safety action: "The ATSB was advised by the aircraft operator that they are upgrading their fleet with carbon brakes from a different manufacturer. As a result, all current main wheel assemblies will be replaced with wheels from that manufacturer; hence, those wheels will have a different part number. The modification program of fitment with new wheels and brakes commenced in February 2015 and will be completed by the end of May 2015."
