Frequently asked questions

Does Airservices need to assess my aircraft noise certification or provide me with a noise certificate?

Airservices does not need to issue a noise certificate or assess the aircraft noise certification if your aircraft is noise-certified and you have evidence of its certification, such as in the approved flight manual.

I am unsure if my aircraft is noise-certified, what do I do?

You should check your Approved Flight Manual and international databases such as the European Aviation Safety Agency Type Certificate Datasheet for Noise (TCDSN) or the Federal Aviation Administration Type Certificate Data Sheets (TCDS) Database to see if your aircraft’s configuration is noise-certified.

If you cannot find the information, please email noise.assessment@airservicesaustralia.com and they will endeavour to assist you. If your aircraft is not certified, you will be required to apply for permission to operate without a noise certificate under Regulation 9A(2)(a) or apply to have your aircraft noise-certified (charges apply for noise certification).

What modifications may affect the noise characteristics of the aircraft?

Any change to the aircraft has the ability to affect the noise characteristics, examples of these include but are not limited to:

  • engine power increase
  • propeller change
  • weight increase
  • exhaust muffler change
  • aerodynamic change
  • other changes affecting flight performance.

I wish to apply for an aircraft noise assessment however I’m yet to receive my aircraft registration. Can I still apply?

Yes, when filling out your application, state that the aircraft registration is ‘to be confirmed’.

What are the compliance responsibilities for Air Navigation (Aircraft Noise) Regulations 1984?

Any aircraft that is not exempt under the Air Navigation (Aircraft Noise) Regulations 1984, is required by Regulation 7A to must carry a noise certificate on board the aircraft at all times – either in the form of a valid deemed assessment, Australian Noise Certificate or other evidence of international noise certification.

Where a permit to operate without a noise certificate has been issued, this also is required to be carried on board the aircraft at all times.

Can I apply for an aircraft noise assessment of an aircraft registered in a country other than Australia?

No. Airservices are only able to conduct assessments for aircraft who are registered in Australia, as per ICAO, Annex 16, Volume I, II-1-1.4.

If you are importing an aircraft from a foreign country, for registration in Australia, please specify Australian registration information.

When is a noise certification test required?

A noise certification test is required when an aircraft type and configuration requires an Australian Noise Certificate and is yet to be noise-certified or when there isn’t sufficient evidence of a noise certificate being issued or recognised by an international authority. If noise testing is required, charges will apply.

Why do I need to provide evidence of existing Noise Certification?

For an aircraft which holds an existing Noise Certification, it can either be Deemed or issued an Australian Noise Certificate. The Aircraft Noise Assessment team will verify that noise certification exists, based on the evidence provided.

Each application is now assessed independently of any previous assessments conducted. This ensures that there is rigour in the process and accountability both of operators and the assessment team.

When do I provide evidence and how do I know what to provide?

You will receive an email upon submission of your application specifying the evidence required. For a Deemed Assessment, evidence must demonstrate that the aircraft holds international noise certification, the certified noise levels and that this certification applies to the aircraft serial number and configuration for which the assessment is being undertaken.

The minimum evidence requirements to demonstrate this are:

  • A Type Certificate Data Sheet (TCDS) – issued by the European Aviation Safety Agency (EASA), the Federal Aviation Administration (FAA) or other international certification bodies recognised by the International Civil Aviation Organisation (ICAO). To be valid. the TCDS must:
    • be the current TCDS
    • be in English
    • include the specific aircraft model and configuration which is being assessed
  • The original Approved Flight Manual (AFM) – this must be the AFM that has been issued to the aircraft serial number for which the application has been submitted. From the AFM, you must supply:
    • the cover page of the AFM which demonstrates that the AFM is allocated to the specific aircraft being assessed, through the display of either serial number or registration for the aircraft
    • page or pages confirming noise certification from the same AFM, including the certified noise levels.

Where can I locate the required evidence of noise certification?

The evidence of noise certification can be made through a combination of sources, though must include the Type Certificate Data Sheet (TCDS) and Approved Flight Manual (AFM), as described previously. While the above evidence is the minimum accepted, you may find that further information is required in order to demonstrate that the aircraft is ‘deemed’ to have a noise certificate.

The below list is not exhaustive but includes the most common sources:

I don’t want to fly at a curfewed airport. Can I apply for a 9A(2)(a) instead of a Deemed Assessment?

If your aircraft has a noise certificate, even though you do not intend to fly into a curfewed airport, you are required to apply for a Deemed Assessment and submit appropriate evidence to support your application.

What is the difference between a Deemed Assessment and an Australian Noise Certificate?

  1. The Deemed Assessment is the most common assessment conducted and compliance method within Australia.
  • The Deemed path is a method of compliance available to aircraft engaging in air navigation within Australia only through Regulation 8 (Deemed) of the Air Navigation (Aircraft Noise) Regulations 1984.
  • This is not to be confused with being issued a Noise Certificate, see 2. for information on noise certificates.
  • Please be aware that this document confirms your compliance based on the evidence provided. While all due care is taken by the assessment team, the owner/operator is responsible under the regulations to ensure that the information and evidence provided is correct. Liability for supplying of incorrect information including aircraft weight, configuration or not supplying the correct flight manual pages, sits with the aircraft owner/operator.

2. The issuing of an Australian Noise Certificate under Regulation 6 of the Air Navigation (Aircraft Noise) Regulations 1984, through validation of existing international noise certification in compliance with the requirements of ICAO, Annex 16, Volume I, is available where satisfactory supporting evidence is supplied to the assessment team.

The issuing of an Australian Noise Certificate:

  • is done by the Certificating Authority
  • requires the submission of satisfactory evidence to enable the assessor to validate that the aircraft holds existing international noise certification that is demonstrated to be at least compliant with the requirements of ICAO, Annex 16, Volume I,
  • will be issued in a minimum of 10 business days – the actual timeframe will vary depending on the individual aircraft and evidence provided,
  • may have associated costs. Costs will need to be agreed and paid, prior to the application being processed and an Australian Noise Certificate issued.

My aircraft will be conducting international air navigation – what do I need?

An Australian Noise Certificate is generally accepted as evidence of compliance under ICAO, Annex 16, Volume I and therefore may be more appropriate for aircraft undertaking international air navigation.

Note – While ICAO, Annex 16, Volume I, II-1.1.8 specifies “Contracting States shall recognize as valid a noise certification granted by another Contracting State provided that the requirements under which such certification was granted are at least equal to the applicable Standards as specified in this Annex” this does not guarantee acceptance by foreign states. Such decision are at the discretion of each individual State, based on their specific regulations and evidence requirements.

For aircraft intending to undertake international air navigation, requirements under international regulations may vary and it is the responsibility of the owner/operator to ensure that the documentation held is acceptable.

Airservices Australia are unable to provide advice on foreign state requirements, or take responsibility for or make guarantees regarding a foreign states acceptance of any assessment or document issued under the Air Navigation (Aircraft Noise) Regulations 1984.

Can I use my mobile phone to capture my Approved Flight Manual (AFM) pages?

We accept any electronic copy of the aircraft’s original AFM. If you are unable to scan the relevant pages, a clear picture of these pages from a digital camera or from your mobile phone camera is an option. Just remember to capture the full page including any document reference numbers at the bottom and top, and ensure they are legible.

Why am I asked to provide aircraft performance specifications?

If you responded ‘no’ to the question, ‘is the aircraft noise certified?’ then you will need to provide performance specifications for your aircraft. These will be used by the Aircraft Noise Assessment team to estimate a noise level and determine whether your aircraft is eligible to be issued a 9A(2)(a) permit.

If these calculations indicate your aircraft is not eligible for a 9A(2)(a) permit, it will require a referral to the Department of Infrastructure and Regional Development for permission to operate.

Does Airservices need to confirm my aircraft’s engine emission certification?

Airservices has been delegated by the Department of Infrastructure and Regional Development to confirm the engine emission certification status for all aircraft, at the point of an Aircraft Environmental Assessment.

In order to minimise the burden on aircraft owner/operators, this process has been incorporated into the previous Aircraft Noise Assessment process and aircraft will not be required to gain confirmation until the point that an aircraft next requires an assessment to be undertaken.

Do I need to email Airservices evidence of my aircraft’s engine emission certification?

No, in most circumstances it is anticipated that evidence required to support a noise assessment will also be sufficient to confirm an aircraft’s engine emission certification. Airservices will not require or request additional evidence, other than that necessary to support the Noise Assessment process.

The Aircraft Noise Assessment team will use submitted evidence, along with a number of other evidence sources, to verify whether an aircraft meets the Aircraft Navigation (Aircraft Engine Emissions) Regulations 1995.

In situations where the evidence provided by the applicant and assessment team resources cannot confirm an aircraft’s engine emission status, the application will be referred to the Department of Infrastructure and Regional Development (the Department) for a determination and the applicant will be notified of the referral. The Department may contact the applicant to request further information.
