Minor Safety Issue
An examination of wheel impact (WILD) data
established that under PN's existing maintenance guidelines there
was no requirement to take wagon RQJW 22034D out of service.
However, running a trend analysis of WILD data clearly showed that
there was a growing wheel impact problem.

The Australian Transport Safety Bureau advises that Pacific
National should consider the implications of this safety issue and
take action where considered appropriate.
