Explanatory Statement
Civil Aviation Safety Regulations 1998
AD/GA8/8 Amdt 1 — Engine Mount Fire Seal Washer
Under section 98 of the Civil Aviation Act 1988 (the Act), the Governor-General may make regulations for the Act and in the interests of the safety of air navigation. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998 (CASR 1998), CASA may issue an airworthiness directive (AD) for a kind of aircraft or aeronautical product. Under subsections 98 (5B) and (5BA) of the Act, an AD is a legislative instrument unless it is expressed to apply in relation to a particular person, a particular aircraft or a particular aeronautical product. Therefore, this AD is a legislative instrument.
Under Annex 8 to the Convention on International Civil Aviation, the State of Design has overall responsibility for continuing airworthiness of an aircraft type, and must provide any information necessary to ensure the continuing airworthiness of a type to appropriate States of Registry. ADs (and their equivalents) are the most common form of continuing airworthiness information, and are issued by most International Civil Aviation Organization Contracting States.
The State of Registry of an individual aircraft is responsible for its continuing airworthiness. Under Annex 8, the State of Registry must develop or adopt requirements to ensure the continuing airworthiness of aircraft.
CASA issued AD/GA8/8 affecting GippsAero GA8-TC 320 aircraft in 2014. As Australia is the State of Design for the type, CASA is required to develop, and to transmit to other States of Registry, an AD to correct a potential risk. The AD required the installation of an approved steel washer at each of the engine mount locations to address a potential risk of reduced engine retention capability in the event of a fire. As a result of a request from GippsAero, the manufacturer of the GA8 series aircraft, CASA has reviewed AD/GA8/8 and decided to amend it to clarify the applicability statement to be inclusive of the affected aircraft serial number range. This AD repeals and replaces the previous AD on this subject.
Consultation
This AD is being made at the request of industry, in particular the manufacturer of the affected aircraft. As this AD amendment is of a minor or machinery nature and does not substantially alter existing arrangements apart from clarifying the applicability statement, it is CASA’s view that it was not necessary or appropriate to undertake any further consultation under section 17 of the Legislative Instruments Act 2003..
Regulation Impact Statement
A Regulation Impact Statement (RIS) is not required because ADs are covered by a standing agreement between CASA and the Office of Best Practice Regulation under which a RIS is not required for ADs.
Statement of Compatibility with Human Rights
A Statement of Compatibility with Human Rights is at Attachment 1.
Making and commencement
The AD has been made by a delegate of CASA relying on the power of delegation under subregulation 11.260 (1) of CASR 1998 and subsection 94 (1) of the Act.
The instrument commences on 1 April 2015.

Overview of the legislative instrument

The AD required the installation of an approved steel washer at each of the engine mount locations to address a potential risk of reduced engine retention capability in the event of a fire.
