The Saab SF-340B aircraft registered VH-TRX departed Dubbo, NSW
on climb to flight level (FL) 170. Passing FL156 the crew reported
that the aircraft had encountered ice and turbulence so they
descended the aircraft to FL130. Given earlier serious icing
incidents in this aircraft type, the ATSB commenced a category 4
investigation to determine if safety was compromised. Following a
comprehensive assessment of available information, no safety issues
were found to have been involved and appropriate procedures were
followed by the crew.

Status: Downgraded the occurrence to category 5
and investigation discontinued.
