Frequently Asked Questions
Why do cancelled ADs no longer have a signature on them?
This is a purely administrative change, we have imporved our process by combining several cancelled ADs onto a single instrument. Legally, nothing has changed. The actual instruments cancelling the ADs can be found here.
What happens when a State of Design AD is published which supercedes an existing CASA AD?
In this instance CASA will cancel the Australian AD as close as possible to the effective date of the State of Design AD. If the State of Design AD becomes effective bofre CASA cancells the Australian AD; the State of Design AD has precidence.
If my aircraft model is already on the Australian register on 1 October 2009, what State of Design ADs must I comply with?
You must comply with applicable State of Design ADs issued on or after 1 October 2009.
If I operate a new model aircraft after 1 October 2009 and that model has not been on the Australian register, what State of Design ADs must I comply with?
You must comply with all applicable State of Design ADs issued before and after 1 October 2009.
Will CASA display State of Design ADs on the CASA website?
Yes - From October 1, we will add the relevant State of Design ADs to the end of the existing AD listings.
Will existing CASA ADs cease to have effect?
No - All CASA ADs issued before October 1, will remain in effect. If a State of Design issues an AD which varies the requirements of an existing CASA AD, we will cancel or amend the CASA AD.
My aircraft is designed in one country but has a type certificate from another country. Which ADs do I need to comply with?
As CASR Part 39 refers to the State of Design, you will need to comply with ADs from the NAA of the country where the aircraft was designed and certificated. The CASA website will list the relevant State of Design NAAs for aircraft, engines and propellers.
Will State of Design equipment ADs be listed on the website?
Yes - All relevant equipment ADs will be listed on the CASA website AD pages at the end of the current equipment type listings.
If the NAA approves an AMOC against a State of Design AD do I have to apply to CASA for an exclusion?
No - If the legal document is the State of Design AD then CASR Part 39 allows automatic acceptance of an AMOC provided by the State of Design NAA against a State of Design AD. (also refer to the following question).
What is the policy for automatic acceptance of AMOCs?
- The AMOC must be approved by the State of Design or a delegate specifically approved by the State of Design.
- The AMOC must not have conditions outside the applicability of Australian aircraft. For example such conditions could include:
- Applicable to the State of Design fleet only
- Applicable to a specific operator(s) or organisation(s)
- Applicable to specific models, line numbers, serial numbers or configurations.
- Applicable to age or life of the aircraft
- A revision of the requirement document to the AD such as a Service Bulletin approved as an AMOC by the State of Design NAA is acceptable.
What Evidence of an AMOC is required?
CASA may require the operator to show evidence of the State of Design AMOC. This evidence includes an approved NAA document that verifies the AMOC has been approved and no restrictions exist that is outside the applicability of the Australian aircraft.
If an Australian AD issued before 1 October 2009 mirrors a State of Design AD, do I have to apply for an exclusion if an AMOC has already been approved by the State of Design NAA?
Yes - As compliance is required against the Australian AD, you will have to apply for an exclusion against the Australian AD.
Will CASA mail State of Design ADs to all registered operators?
No - CASA will only notify registered operators when an emergency State of Design AD has been issued.
Will the AD hard copy AD books and amendment service continue?
No - As CASA will no longer routinely rewrite State of Design ADs and issue them as Australian ADs, there will be no hard copy AD books or AD amendment service after Issue 12/2009.
Diamond aircraft can be manufactured in Austria under the EASA Type Certificate or in Canada under a Canadian one, but otherwise are identical. They can also be certified in Australia based on the FAA Type Certificate. As the parent company is Austrian, does that make Austria the State of Design for all Diamond aircraft so Austrian/EASA ADs apply, or do Canadian ADs apply to Canadian built aircraft? What about FAA certified aircraft?
as Austria is the state of design for the Diamond aircraft, you will have to comply with Austrian (EASA) ADs no matter where the aircraft was built.
The Cessna 208B Caravan aircraft originally built in the USA can be certified in Australia based on either the FAA TC or the UK CAA TC. The Australian CTA (A32 Issue 2) says that "any conditions or restrictions placed on 208B aircraft by the UK CAA, in addition to those of the FAA, will automatically apply to Australian registered 208B aircraft equipped with eleven or more seats." Does this mean that FAA ADs, UK ADs or both would apply to Australian registered 208B aircraft certified under the UK TC?
As the Cessna 208 is an American designed aircraft it will have to comply with FAA ADs. In special cases like the 208B with extra seats, if anything is issued the UK CAA, CASA will either issue an Australian AD or offer advise to operators depending on the circumstances.
