Consultation open: Proposed updated rules for aerodromes (NPRM 1426AS)
29 August 2017
A proposal to update the Part 139 ruleset for aerodromes is now available for public consultation, following a comprehensive post-implementation review.
The amendments to rules in Part 139 of CASR and the Part 139 Manual of Standards reflect changes in the industry, technology, international standards and best practice. They aim to be more flexible and practical.
Proposed changes at a glance
- Aerodromes will be either 'regulated' (certified) or 'unregulated' – based on the presence of instrument flight procedures – reducing complexity.
- Administrative and system requirements will be scalable, dependent on the size and complexity of the aerodrome operations and associated risk.
- Physical standards will be more flexible, with minimum, maximum and new 'preferred' limits to suit a variety of practical situations. These design standards can be implemented as infrastructure is built, replaced or upgraded.
- There are new options and standards to use enhanced visual aids to improve safety.
- Inspection and reporting requirements for all aerodromes will support risk-based regulatory surveillance.
- Existing aerodrome facilities will continue to be 'grandfathered' until they are upgraded or replaced.
- Aerodromes currently issued exemptions under Part 11 of CASR may now be granted a wider range of enduring approvals subject to a suitable safety case being provided to CASA.
CASA encourages aerodrome operators, aerodrome consultants, service providers and planning approval bodies to read the notice of proposed rulemaking (NPRM) and make a submission via the CASA Consultation Hub.
Consultation closes 8 December 2017.
