Local and national air traffic control procedures did not prescribe the means for controllers to indicate in the air traffic control system that a parachute drop clearance had been issued.
Following the occurrence, on 28 June 2012, Airservices made changes to its National ATS (Air Traffic Services) Procedures Manual to include The Australian Advanced Air Traffic System human-machine interface requirements in section 5-15 titled Parachuting.
The ATSB is satisfied that the action taken by Airservices Australia has adequately addressed the safety issue.
