Cessna Aircraft Company 310R, VH-ALY

Preliminary investigation was undertaken into a category 4
occurrence involving a Cessna 310R aircraft that had been issued a
clearance to cross runway 06 at Jandakot Airport while a Cessna
Citation 550 aircraft was on final approach to land. The Citation
had been issued a landing clearance. The ATSB has terminated the
investigation based on information from Airservices Australia that
there had been an inadvertent omission by the controller in
following an established check procedure. There was relatively
little safety benefit to be gained from continuing the
investigation compared with other priorities.

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