CASR Part 45 - Display of nationality and registration marks and aircraft registration identification plates
Part 45 describes the requirements for the markings and the display of markings and identification plates of Australian registered aircraft.
ac45c01.pdf (pdf 253.22 KB) - Nationality and Registration Marks (March 2010) - This Advisory Circular (AC) provides guidance and information in relation to aircraft markings.
Part 45 is currently subject to a Post Implementation Review (PIR).
Post Implementation Review (PIR) of the existing regulations
In October 2000 Part 45 of CASR's 1998 replaced Division 6 of Part 3 of the CAR's 1988. That CAR was not fully compliant with the ICAO Annex 7 recommendations.
Amongst other things, Part 45 required marks to have a minimum height of 300mm, against the previous requirement for a minimum height of 150 mm. CASA is aware that certain sectors have found difficulty in complying with the increased size of the markings and with other requirements of the regulations.
Additionally, technological restrictions imposed by certification limitations on new generation composite aircraft were not considered and are not addressed in Part 45. Some technical restrictions have resulted in the inability to comply with the marking requirements on the lateral surfaces and on the wings on some aircraft due to structural requirements. This has required CASA to exempt certain types from compliance with some sections of Part 45. Thus far, exemptions have been issued for the Cirrus SR Series and the Diamond DA-42. Although CASA acknowledges that composite material requirements were not apparent or considered in 2000, they reinforce the necessity to review the existing regulations.
This situation also raises the question of the currency of ICAO Annex 7 standards and the need for a more flexible set of Standards and Recommendations, as the current edition does not cater for contemporary operational and technical requirements applicable of the modern Australian fleet.
The objective of the PIR of Part 45 is to identify the existing limitations of the regulations and to address how they are to be rectified. CASA's proposed changes are detailed in the attached review document.
The review document takes into account the best practices of the ICAO contracting states, as noted on the current differences to Annex 7 – e.g. the USA FAA exempting marking under the wings and New Zealand CAA exempting aircraft from displaying their nationality while flying within their territory.
Some of the new proposals will require the Commonwealth to record differences to Annex 7.
The suggested changes reduce the number of regulations from 170 to 70.
The review document was posted on the Standards Consultative Committee (SCC) forum on 20 July 2007 for one month for their consideration and comment.
After all SCC comments have been reviewed and any applicable changes have been incorporated into a Notice of Proposed Rule Making (NPRM), the NPRM will be promulgated on the CASA website to allow comment from the aviation industry.
After input has been received from industry, the policy will be reviewed as required, and the new regulations will be drafted by the Office of Legislative Drafting. The draft regulations will be reviewed by CASA and the SCC and the final version will be forwarded to DOTARS who will arrange for the eventual making of the new regulation.
Exemption - Display of marking and carriage of identification plate
Due to anticipated delays in the legal drafting process it could be some time before revised regulations can be introduced. Therefore, to overcome the difficulties experienced in complying with the current regulations, CASA has issued a general exemption to some of the Part 45 regulation. The exemption applies only to fixed-wing and rotor craft of less than 5700kg, operating wholly within Australian territory. The exemption is effective from 5 February 2008.
Under the terms of the exemption, applicable aircraft will be exempt from:
Displaying markings on the undersurface of the wings
Displaying lateral markings of 300mm - Under the terms of the exemption the minimum height must be 150mm.
Carrying an aircraft registration identification plate, provided the aircraft carries a manufacturer’s data plate.

Reserving a mark
Who is entitled to apply for the reservation of a registration mark?
Members of the aviation industry and new entrants can reserve registration marks, for a period of 12 months, for: a) assignment to aircraft which are to be registered in the Australian Civil Aircraft Register; or b) for the purpose of changing a registration mark already assigned to a registered aircraft.
How to apply for the reservation of a registration mark
The registration mark must be reserved against an aircraft, preferably identified by its manufacturer, model and serial number
If full details cannot be supplied, the reservation request must be accompanied by written justification for such a request. The reservation will be processed subject to CASA's approval
The reservation is valid for a period of 12 months or until placement on a registered aircraft, whichever occurs first. A mark that is not assigned to a registered aircraft by the end of the 12 months reservation period will expire and become available for use.
If CASA is not satisfied with the authenticity of any of the information provided through Form 028 - Application for Mark Reservation, or its complementary documentation, CASA may require the applicant to provide further information or documentation, as described in the notice. CASA may refuse to further consider the application until the applicant complies with the notice.
The list includes marks whose periods of reservation have expired.
What are the main requirements?
Whilst reserved to an aircraft the mark must not be placed on another aircraft unless CASA receives written consent to that effect from the holder of the reservation.
Any person other than the reservation holder cannot use the mark unless the reservation holder relinquishes control of the mark by providing CASA with written consent to that effect.
Confirmation of reservation
The issue of a Confirmation of Reservation confirms approval of an application for reservation. It will be automatically cancelled at the close of business of the expiring date noted on the Confirmation, or when the aircraft to which the mark has been reserved is registered, whichever occurs first.
Release of Information about a Reserved Mark
In order to comply with the Privacy Act 1988 CASA will not release the name, address or any other details about an individual or organisation that has reserved a mark.
Furthermore, CASA will not facilitate any negotiations relating to the release or transfer of a reserved mark.
When a mark becomes available for reservation it will be shown in the list of available marks on the CASA website. This list is routinely updated each working day.
