Explanatory Statement

Civil Aviation Safety Regulations 1998

AD/LUB/2 Amdt 2 — Oil Filter Adapters

Legislation

Under section 98 of the Civil Aviation Act 1988 (the Act), the Governor-General may make regulations for the purpose of carrying out and giving effect to the provisions of the Convention on International Civil Aviation relating to safety, amongst other things. Under regulation 39.001 of the Civil Aviation Safety Regulations 1998 (CASR), the Civil Aviation Safety Authority (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.

Subsection 98 (5D) of the Act provides that a legislative instrument made under the Act or the regulations may apply, adopt or incorporate any matter contained in any instrument or other writing as in force or existing from time to time, even if the other instrument or writing does not yet exist when the legislative instrument is made.

Under subsection 33 (3) of the Acts Interpretation Act 1901, where an Act confers a power to make, grant or issue any instrument of a legislative or administrative character (including rules, regulations or by-laws), the power shall be construed as including a power exercisable in the like manner and subject to the like conditions (if any) to repeal, rescind, revoke, amend, or vary any such 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 or aeronautical products.

AD/LUB/2 Amdt 2 applies to piston engines manufactured by Teledyne Continental Motors.

CASA issued AD/LUB/2 to address reports of engine failure events resulting from the loss of engine oil. The oil loss was found to have resulted from loose and/or leaking oil filter adapters.

AD/LUB/2 Amdt 1 removed the requirement to inspect the oil filter adapter at every oil filter change and became effective on 15 April 2004.

 

AD/LUB/2 Amdt 2 is issued in response to a request from the public to identify compatible parts more accurately for the various adapter configurations and expands the compliance statement to identify relevant maintenance schedule inspection thresholds. This AD repeals and replaces the previous AD on this subject.

Documents Incorporated by Reference

No documents are incorporated by reference in AD/LUB/2 Amdt 2.

Consultation

This AD is being made at the request of industry, in particular a maintainer of a Teledyne Continental Motors piston engine to clarify the requirements of an existing AD. As this AD amendment is of a minor or machinery nature and does not substantially alter existing arrangements apart from changing a regulatory reference, it is CASA’s view that it was not necessary or appropriate to undertake any further consultation under section 17 of the Legislation Act 2003.

Sector risk, economic and cost impact

Subsection 9A (1) of the Act states that, in exercising its powers and performing its functions, CASA must regard the safety of air navigation as the most important consideration. Subsection 9A (3) of the Act states that, subject to subsection (1), in developing and promulgating aviation safety standards under paragraph 9 (1) (c), CASA must:

(a) consider the economic and cost impact on individuals, businesses and the community of the standards; and

(b) take into account the differing risks associated with different industry sectors.

The cost impact of a standard refers to the direct cost (in the sense of price or expense) which a standard would cause individuals, businesses and the community to incur. The economic impact of a standard refers to the impact a standard would have on the production, distribution and use of wealth across the economy, at the level of the individual, relevant businesses in the aviation sector, and the community more broadly. The economic impact of a standard could also include the general financial impact of that standard on different industry sectors.

The economic and cost impact of the instrument has been determined by:

(a) the identification of individuals and businesses affected by the instrument;

(b) consideration of how the requirements to be imposed on individuals and businesses under the instrument will be different compared to existing requirements;

(c) a valuation of the impact, in terms of direct costs on individuals and businesses affected by the instrument to comply with the different requirements. This valuation is consistent with the principles of best practice regulation of the Australian Government.

CASA has assessed that the economic and cost impact of the instrument is not significant. The requirements of the instrument apply to holders of certificates of registration of relevant aircraft.

Impact on categories of operations

The instrument is likely to have a beneficial effect on operations conducted by the relevant aircraft because it clarifies the requirements of an existing AD.

Impact on regional and remote communities

The instrument will not have a negative impact on regional and remote communities.

Office of Impact Analysis (OIA)

An Impact Analysis (IA) is not required because ADs are covered by a standing agreement between CASA and OIA under which an IA is not required for ADs (OIA id: 14507).

Statement of Compatibility with Human Rights

A Statement of Compatibility with Human Rights is at Attachment 1.

Making and commencement

The instrument has been made by a delegate of CASA relying on the power of delegation under subregulation 11.260 (1) of CASR and subsection 94 (1) of the Act.

As an instrument relating to aviation safety made under CASR, Part 4 of Chapter 3 of the Legislation Act 2003 (sunsetting of legislative instruments) does not apply to this instrument (item 15 of the table in section 12 of the Legislation (Exemptions and Other Matters) Regulation 2015). The instrument requires that the action set out in the instrument, that relates to aircraft or aeronautical products, be taken to correct an unsafe condition. As such, the instrument is intended to have enduring operation and it would not be appropriate for it to be subject to sunsetting.

The instrument commences on 15 July 2023.

Civil Aviation Safety Authority

Overview

The Civil Aviation Safety Regulations 1998 Amendment (Oil Filter Adapters) 2023 (F2023L00952) was introduced to address specific issues related to piston engines manufactured by Teledyne Continental Motors, particularly those involving engine failure events due to the loss of engine oil caused by loose or leaking oil filter adapters. The amendment was initiated by the Civil Aviation Safety Authority (CASA) under the authority granted by the Civil Aviation Act 1988. The policy objective of this legislative instrument is to ensure the continuing airworthiness of the affected aircraft by providing clearer guidelines on compatible parts for various adapter configurations and expanding the compliance statement to specify relevant maintenance schedule inspection thresholds. This amendment aims to improve safety standards without imposing significant economic or cost burdens on individuals or businesses in the aviation sector.

Scope and Application

The AD/LUB/2 Amdt 2, issued under the Civil Aviation Safety Regulations 1998 (CASR), applies specifically to piston engines manufactured by Teledyne Continental Motors. This amendment is a response to reports of engine failure events due to oil loss, which was traced to loose or leaking oil filter adapters. The amendment repeals and replaces AD/LUB/2 Amdt 1, removing the requirement to inspect the oil filter adapter at every oil change. Instead, it introduces more precise identification of compatible parts for various adapter configurations and expands the compliance statement to specify relevant maintenance schedule inspection thresholds. The AD applies to the State of Registry of an individual aircraft, which is responsible for its continuing airworthiness, and is issued by the Civil Aviation Safety Authority (CASA). This instrument does not incorporate any documents by reference. Given the minor nature of the changes, CASA determined that further consultation was not necessary or appropriate. The instrument, which aims to clarify existing requirements, is expected to have a beneficial effect on the operations of the relevant aircraft. It is also compatible with human rights as it does not engage any applicable rights or freedoms. The AD/LUB/2 Amdt 2 will commence on 15 July 2023.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR) provide a framework for the issuance of airworthiness directives (ADs) by the Civil Aviation Safety Authority (CASA) under section 39.001. These directives are critical for ensuring the continuing airworthiness of aircraft and aeronautical products, as outlined in Annex 8 to the Convention on International Civil Aviation. AD/LUB/2 Amdt 2 specifically pertains to piston engines manufactured by Teledyne Continental Motors, addressing issues related to engine oil loss caused by loose or leaking oil filter adapters. This amendment to AD/LUB/2 clarifies the requirements for identifying compatible parts and specifies maintenance schedule inspection thresholds, thereby replacing the previous directive which mandated inspection of oil filter adapters at every oil change. Entities governed by AD/LUB/2 Amdt 2, particularly those involved in the maintenance and operation of Teledyne Continental Motors piston engines, must comply with the new requirements. This includes ensuring that oil filter adapters are correctly identified and inspected as per the new maintenance schedule outlined in the AD. Compliance involves maintaining records that demonstrate adherence to the specified inspection intervals and procedures, ensuring that all maintenance activities meet the safety standards set forth by CASA. Breach of the provisions of AD/LUB/2 Amdt 2 could result in significant safety risks, as non-compliance with ADs can lead to unsafe conditions that may compromise the airworthiness of the aircraft. Although the explanatory statement does not explicitly detail specific offences or penalties, non-compliance with ADs generally may result in enforcement actions by CASA, including fines, suspension or revocation of certificates of airworthiness, and other regulatory measures. The potential consequences underscore the importance of adhering to the AD to maintain the highest safety standards in aviation. The economic and cost impact analysis indicates that the requirements of AD/LUB/2 Amdt 2 are not significant. This conclusion is based on the assessment that the changes primarily involve clarification of existing requirements rather than imposing new, costly obligations. The analysis considered the direct costs to individuals and businesses, as well as the broader economic impact, concluding that the amendment would not impose a substantial financial burden. Additionally, the instrument’s compatibility with human rights has been affirmed, with no adverse implications identified for the rights and freedoms recognized in the relevant international instruments.
