Mandatory Compliance with State of Design Airworthiness Directives

- Changes from 01 Oct 2012

This information was updated 10 Oct 2012

Introduction

From 1 October 2012, the Civil Aviation Authority of New Zealand (CAA) will no longer issue New Zealand Airworthiness Directives (NZ ADs) for individual aircraft types which were usually produced by rewriting the text of the State of Design ADs. (This has always been the case for large aircraft with MCTOW over 5700 kg which have always been required to comply with State of Design ADs.) 

Therefore, after that date when a State of Design AD is issued for an aircraft, instead of re-writing it as a NZ AD the CAA will simply call up the foreign AD in the NZ AD Schedule for that aircraft. 

This means that an operator of an aircraft below 5700 kg MCTOW must comply with NZ ADs applicable to the aircraft, engine, propeller and equipment issued prior to 1 October 2012 and every State of Design AD applicable to the aircraft, engine, propeller and equipment issued or revised on or after 1 October 2012.  Where an earlier NZ AD is based on a foreign AD, compliance may be shown with either the NZ AD or the equivalent State of Design AD, because they will have essentially the same requirements.

From 1 October 2012 the CAA will continue to maintain NZ AD Schedules on the CAA web site. However, after that date the NZ AD Schedules will comprise all the NZ ADs issued prior to the changeover date of 1 October 2012, and just list the State of Design ADs issued or revised after that date. The NZ AD Schedules will be updated at the end of every month as is done now.

The CAA will still notify aircraft operators in writing and send copies of any Emergency ADs directly when an Emergency State of Design AD is issued.

The CAA is not publishing the wording of State of Design ADs because these are now readily available on the internet. In the event that an AD is received only in paper copy format, then the CAA would make the AD available on the CAA web site. Links to NAA web sites are available on the CAA web site.

How will this work?

For example if you operate a Cessna 152 aircraft which is designed in the USA, compliance is required with NZ ADs issued prior to 1 October 2012 and FAA ADs issued or revised on or after 1 October 2012. This includes compliance with ADs for the aircraft, engine, propeller and equipment, which in this case are also designed in the USA.

In the case of equipment for smaller aircraft below 5700 kg MCTOW, the CAA will add the State of Design AD number and the effective date to the relevant NZ Component AD Schedule (eg DCA/RAD, DCA/INST/, DCA/EQUIP, etc.).

In support of the above the CAA will provide the following:

  • Maintain NZ AD Schedules on the CAA web site by listing the State of Design AD number, the AD title and the AD effective date on the NZ AD schedules.
  • Provide links on the CAA web site to the applicable NAA AD web page where operators and maintainers can If an unsafe condition exists in an aircraft or aeronautical product, the CAA will still be able to issue a NZ AD in accordance with section 72I(3A) of the Civil Aviation Act 1990. These ADs will be added to the applicable NZ AD schedule. Operators of an aircraft must comply with all applicable ADs issued by the CAA.
  • By notice given in the Gazette the State of Design ADs will be deemed to be NZ ADs in accordance with section 72I(3B) of the Civil Aviation Act 1990.
  • When an emergency AD is issued, the CAA will provide notification in writing to operators in accordance with section 72I(3C) of the Civil Aviation Act 1990.

How do I obtain a State of Design AD?

State of Design ADs can be obtained directly from the applicable NAA web site. These are usually quite easy to find on the internet. Links to NAA web sites are available on the CAA web site. The CAA will list the State of Design AD number and the effective date at the end of existing NZ AD Schedules.

Will the CAA send me the State of Design ADs?

No, the CAA will only provide notification in writing to operators when an emergency AD is issued. The CAA will also provide an email notification service to subscribers when an emergency AD is issued.

Will an NAA Alternate Means of Compliance (AMOC) be accepted by the CAA?

An AMOC provided by the State of Design NAA against a State of Design AD will not be automatically accepted by the CAA because the CAA needs to assess whether the reasons for the AMOC are still relevant or applicable in New Zealand. For approval of a CAA AMOC based on a foreign AMOC, an applicant must apply for a CAA AMOC by submitting form CAA 24039/01 to the CAA.

Frequently Asked Questions

What happens when a State of Design Airworthiness Directive (AD) is issued by a National Aviation Authority (NAA) which supersedes an existing Civil Aviation Authority (CAA) of New Zealand (NZ) AD?

The CAA will cancel the superseded NZ AD when the NZ AD Schedule is revised at the end of every month as close as possible to the effective date of the State of Design AD.  If the State of Design AD becomes effective before the CAA cancels the NZ AD, then the State of Design AD takes precedence.

From 1 October 2012 the CAA will maintain the NZ AD Schedules on the CAA web site by adding the State of Design AD number and effective date to the NZ AD schedule. This action will occur at the end of every month as close as possible to the effective date of the State of Design AD. (i.e. the same way the NZ Schedules are revised now. The only difference is that instead of adding a NZ AD there will just be a State of Design AD number and effective date listed.)

If an aircraft is already on the NZ register on 1 October 2012, what State of Design ADs must be complied with?

An operator of an aircraft below 5,700 kg MCTOW must comply with NZ ADs applicable to the aircraft, engine, propeller and equipment issued prior to 1 October 2012 and every State of Design AD applicable to the aircraft, engine, propeller and equipment issued or revised on or after 1 October 2012. Where a NZ AD is based on a foreign AD, compliance may be shown with either the NZ AD or the equivalent State of Design AD. i.e. the logbook will need to list all the NZ ADs, but the CAA will accept compliance with the equivalent State of Design AD as a means of compliance with the NZ AD. (The same as happens now for an imported aircraft.)

If an aircraft is registered in NZ after 1 October 2012 and that aircraft has not been on the NZ register before, what State of Design ADs must be complied with?

An operator of an aircraft below 5,700 kg MCTOW must comply with NZ ADs applicable to the aircraft, engine, propeller and equipment issued prior to 1 October 2012 and every State of Design AD applicable to the aircraft, engine, propeller and equipment issued or revised on or after 1 October 2012. Where a NZ AD is based on a foreign AD, compliance may be shown with either the NZ AD or the equivalent State of Design AD. i.e. the logbook will need to list all the NZ ADs, but the CAA will accept compliance with the equivalent State of Design AD as a means of compliance with the NZ AD. (The same as happens now for an imported aircraft.)

If a new aircraft type or variant is registered in NZ after 1 October 2012, what State of Design ADs must be complied with?

An operator of a new aircraft type or variant below 5,700 kg MCTOW must comply with every State of Design AD applicable to the aircraft, engine, propeller and equipment issued before and after 1 October 2012. If a NZ AD schedule for a new aircraft type or variant does not exist on the CAA web site, then the CAA will create a NZ AD Schedule on the CAA web site listing the applicable State of Design AD numbers and effective dates.

Will the CAA display State of Design ADs on the CAA web site from 1 October 2012?

No. The State of Design AD number and effective date only will be listed on the NZ AD Schedule. The actual State of Design AD can be obtained directly from the applicable NAA web site. Links to NAA web sites are available on the CAA web site.

Will existing NZ ADs cease to have effect?

No. All NZ ADs issued before 1 October 2012 will remain in effect. If a NAA issues a State of Design AD which changes the requirements in an existing NZ AD, the CAA will cancel or amend the NZ AD. If the State of Design AD becomes effective before the CAA cancels the NZ AD, then the State of Design AD takes precedence.

Will the CAA cease to issue NZ ADs?

No. In accordance with the Civil Aviation Act 1990, Section 72I (3A), the CAA will still be able to issue a NZ AD if an unsafe condition is found to exist in an aircraft or aeronautical product in New Zealand.

The aircraft is designed in one country but has a type certificate from another country. Which ADs must be complied with?

Compliance is required with ADs from the NAA of the State of Design. This is defined as the country where the applicable type certificate was issued.  NZ AD schedules will state the NAA State of Design type certificate for aircraft, engines and propellers. (In a few odd cases this can become complicated, but if you are unsure contact the CAA Aircraft Certification Unit for advice. For example a Eurocopter may have an FAA Type Certificate reference on the data plate because it was first sold to that country. However, the CAA would still consider EASA to be the State of Design.)

Will State of Design component and equipment ADs be listed on the NZ AD schedules?

Yes. All relevant State of Design component and equipment ADs will be listed in the existing component and equipment NZ AD schedules.

If the NAA approves an Alternate Means of Compliance (AMOC) against a State of Design AD does the operator of an aircraft have to apply for a CAA AMOC?

Yes. An AMOC provided by the State of Design NAA against a State of Design AD will not be automatically accepted by the CAA because the CAA needs to assess whether the reasons for the AMOC are still relevant or applicable in New Zealand.  For approval of a CAA AMOC based on a foreign AMOC, an applicant must apply for a CAA AMOC by submitting form CAA 24039/01 to the CAA.

Will the CAA mail State of Design ADs to all registered operators?

No. The CAA will only notify aircraft operators in writing when an Emergency State of Design AD is issued.
