Draft AC 139.C-06 v1.0 - Skid resistance of aerodrome pavements and Draft AC 139.C-07 v1.0 - Strength rating of aerodrome pavements (Part 139 consequential ACs)

Closed 10 Sep 2020

Opened 12 Aug 2020


Civil Aviation Safety Amendment (Part 139) Regulations 2019 was made on 21 February 2019.

Effective 13 August 2020, the Part 139 of CASR amendment:

    • establishes a single certification framework for regulated aerodromes (certified)
    • mandates that an aerodrome must be certified based on the publication of a terminal instrument flight procedure
    • sets out the standards for the construction, maintenance and operation of certified aerodromes
    • defines the requirements for aerodrome radiocommunication services at all aerodromes
    • requires the identification of hazards, on aerodromes and within the prescribed airspace. 

The revised Part 139 (Aerodromes) Manual of Standards (Part 139 MOS) was published on 6 September 2019 and will also come into effect on 13 August 2020, replacing the Part 139 Manual of Standards – Aerodromes (version 1.14).

Aerodrome pavements are critical to the safe, efficient and economic operation of the aerodrome. To ensure that hazards to aircraft are minimised they must be constructed and maintained in a suitable condition for the particular demands of the intended aircraft operations.

Advisory Circulars

Advisory Circulars (ACs) will be progressively published and circulated to industry to provide guidance in understanding the new rules.

Through this consultation process CASA invites you to review and provide comment on the following:

  • Draft AC 139.C-06 v1.0 - Skid resistance of aerodrome pavements
  • Draft AC 139.C-07 v1.0 - Strength rating of aerodrome pavements  

Please note, each AC has its own page in this consultation.

Why we are consulting

CASA recognises the valuable contribution that community and industry consultation makes to the regulatory development process. For this reason, we are seeking feedback on whether the draft ACs provide adequate guidance on:

  • skid resistance requirements of aerodrome pavements
  • bearing strength and rating of aerodrome pavements

A copy of each draft AC is provided below and on the survey page for each AC.

Please read the guidance documents before providing your feedback.

Comments should be submitted through the online response form.

Information about how we consult and how to make a confidential submission is available on the CASA website.

To be notified of any future consultations, you can subscribe to our consultation and rulemaking mailing list.

File uploads

Please note: CASA can no longer offer the option to upload files because of the potential risk of malware.

Using an iPad

If you are using an iPad to complete the survey you will be asked to 'download the relevant PDF'. Depending on the software you have on your iPad you may need to download the free viewer to review the single document PDF files. Where a file is a 'multi-file or portfolio PDF you will need to source the Adobe free view - available from iTunes. 

What happens next

At the end of the consultation period, we will review each submission received through the online response form. All submissions will be publicly available on the CASA website, unless you request your submission remain confidential. We will also publish a Summary of Consultation which summarises the feedback received, outlines any intended changes and our plans for the ACs.
