Post-implementation review (PIR)
Standards Development project AS 04/02 has been approved to conduct a PIR of the Part 173 MOS. The PIR will review and amend the Part 173 MOS with the intent of amending its standards and provisions to reflect changes to technology and industry developments. This amendment process may proceed on a topic-by-topic basis to avoid large scale changes to the procedures design operating environment.
Any amendments will be developed in close consultation with industry through the Airspace and Infrastructure Users Group and issued in draft form for public comment. CASA will send notification via the Airspace and Aerodromes mailing list when proposed amendments are available for public consultation.
Part 173 can be found in volume 4 of the CASR. Note that recent amendments to this Part may be listed in the Unincorporated Amendments.
