Civil Aviation Act 1988

Civil Aviation Order 100.5 Amendment Instrument 2013 (No. 3)

 

Purpose

The purpose of Civil Aviation Order 100.5 Amendment Instrument 2013 (No. 3) (the CAO amendment) is to modify the list of aircraft whose manufacturers’ maintenance schedules CASA has declared to be inadequate and not to be used as an aircraft’s maintenance schedule.

 

Legislation

Section 98 of the Civil Aviation Act 1988 (the Act) empowers the Governor-General to make regulations for the Act and the safety of air navigation.

 

Under subregulation 42A (6) of the Civil Aviation Regulations 1988 (CAR 1988), CASA may, for the purpose of ensuring the safety of air navigation, declare in writing that a manufacturer’s maintenance schedule that CASA thinks is inadequate must not be used as an aircraft’s maintenance schedule.

 

Under regulation 5 of CAR 1988, CASA may, among other things, issue notifications in Civil Aviation Orders (CAOs).

 

Under paragraph 8.1 of Civil Aviation Order 100.5 (CAO 100.5), CASA has declared that the manufacturers’ maintenance schedules for specified aircraft are inadequate and must not be used as the maintenance schedules for the aircraft. Prior to the CAO amendment, those aircraft included all Waco aircraft.

 

Background

The WACO YMF-F5 and YMF-F5C series aircraft, manufactured by WACO Classic Aircraft Corporation, are a modern incarnation of the original WACO design of 1930s origins, manufactured by the WACO Aircraft Company, which had an inadequate maintenance schedule. These more modern WACO YMF-F5 and YMF-F5C aircraft have a supplemental type certificate (STC) SA1000GL, issued by the Federal Aviation Authority (FAA) of the United States of America, incorporated at manufacture. The STC includes the use of modern materials and manufacturing methods and other design changes which significantly enhance the original design. Essentially, the modern WACO YMF-F5 and YMF-F5C aircraft are new build aircraft.

 

The more modern WACO YMF-F5 and YMF-F5C aircraft also have a comprehensive Maintenance Manual (YMFAMM-1) and a Jacobs Aircraft Engine Operators Manual (R-755A, B & S), which were previously not available to the original 1930s WACO aircraft. These manuals have been reviewed by CASA and found to be appropriate to be considered together as an approved manufacturers maintenance program.

 

Both original WACO aircraft and the more modern WACO YMF-F5 and YMF-F5C series aircraft are on the Australian Register.

 

CAO 100.5 required registered operators of the more modern WACO YMF-F5 and YMF-F5C series aircraft to use the CASA maintenance schedule set out in Schedule 5 of CAR 1988 (the CASA maintenance schedule), rather than the manufacturers maintenance manuals YMFAMM-1 and R755A, B & S.

 

Before the CAO amendment, the valid manufacturer recommended maintenance intervals for these more modern versions of the WACO aircraft were not approved for use.

 

CAO amendment

This instrument amends paragraph 8.1 of CAO 100.5 so that WACO Classic Aircraft Corporation YMFF5 and YMFF5C series aircraft that have FAA STC SA1000GL incorporated at manufacture are excluded from the list of aircraft for which the manufacturers’ maintenance schedules must not be used as the aircraft’s maintenance schedules. The CAO now distinguishes between the aircraft manufactured to the original design of 1930s origins by the WACO Aircraft Company and the newer WACO YMF-F5 and YMF-F5C series aircraft manufactured by WACO Classic Aircraft Corporation.

 

Legislative Instruments Act 2003 (LIA 2003)

Under subsections 98 (5) and 98 (5AAA) of the Act, where the regulations provide for certain instruments to be issued in the form of CAOs, such CAOs are legislative instruments. The CAO amendment is, therefore, a legislative instrument and it is subject to registration, and tabling and disallowance in the Parliament, under sections 24, and 38 and 42, of the LIA 2003.

 

Consultation

A proposal to amend paragraph 8.1 of CAO 100.5 was notified on the CASA website as Project CS 13/05. The proposal was supported by the Aviation Maintenance, Repair and Overhaul Business Association, which represents the maintenance, repair and overhaul segment of Australias aviation industry. No objections were received during its 2 week consultation period. In these circumstances, CASA believes that no further consultation is necessary or appropriate.

 

Office of Best Practice Regulation (OBPR)

OBPR assessed that the proposed amendment is minor in nature and that no further analysis in the form of a Regulation Impact Statement was required (OBPR ID: 16129).

 

Statement of Compatibility with Human Rights

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

 

Making and commencement

The CAO amendment has been made by the Director of Aviation Safety, on behalf of CASA, in accordance with subsection 73 (2) of the Act.

 

The CAO amendment commences on the day of registration.

Attachment 1

Statement of Compatibility with Human Rights

Prepared in accordance with Part 3 of the
Human Rights (Parliamentary Scrutiny) Act 2011

 

Civil Aviation Order 100.5 Amendment Instrument 2013 (No. 3)

 

This legislative instrument is compatible with the human rights and freedoms recognised or declared in the international instruments listed in section 3 of the
Human Rights (Parliamentary Scrutiny) Act 2011.

 

Overview of the legislative instrument

The legislative instrument modifies the list of aircraft for which CASA has declared that the manufacturer’s maintenance schedule must not be used.

 

The purpose of the CAO amendment is to allow the manufacturer’s maintenance schedule to be used for WACO Classic Aircraft Corporation YMFF5 and YMFF5C series aircraft that have supplemental type certificate SA1000GL, issued by the Federal Aviation Administration of the United States of America, incorporated at manufacture. These are modern aircraft for which the manufacturer’s maintenance schedule is adequate. This legislative instrument distinguishes them from other WACO aircraft, which were predominantly built before and during World War II and for which the manufacturer’s maintenance schedule is inadequate.

 

Human rights implications

This legislative instrument does not engage any of the applicable rights or freedoms.

 

Conclusion

This legislative instrument is compatible with human rights as it does not raise any human rights issues.

Civil Aviation Safety Authority

Overview

The Civil Aviation Order 100.5 Amendment Instrument 2013 (No. 3) was introduced to address the inadequacy of maintenance schedules for certain aircraft, specifically those manufactured by WACO Classic Aircraft Corporation. Enacted by the Australian Government, this instrument amends the Civil Aviation Order 100.5 to exclude the more modern WACO YMF-F5 and YMF-F5C series aircraft from the list of aircraft whose manufacturers' maintenance schedules are deemed inadequate. The policy objective is to ensure the safety of air navigation by allowing the use of approved manufacturer's maintenance programs for these aircraft, which have been found to have comprehensive and suitable maintenance manuals. The instrument was developed under the authority of the Civil Aviation Act 1988, which empowers the Governor-General to make regulations concerning the safety of air navigation, and it is subject to registration, tabling, and disallowance under the Legislative Instruments Act 2003. The amendment was supported by industry stakeholders and did not require further consultation or regulatory impact analysis, as it was deemed minor in nature.

Scope and Application

The Civil Aviation Order 100.5 Amendment Instrument 2013 (No. 3) amends the Civil Aviation Order 100.5, which is a subordinate instrument of the Civil Aviation Act 1988, to modify the list of aircraft whose manufacturers’ maintenance schedules are deemed inadequate by the Civil Aviation Safety Authority (CASA). This amendment applies specifically to WACO Classic Aircraft Corporation's YMF-F5 and YMF-F5C series aircraft that have a Federal Aviation Administration (FAA) supplemental type certificate SA1000GL incorporated at manufacture. These aircraft are distinguished from the older WACO aircraft, which were manufactured by the WACO Aircraft Company and whose maintenance schedules are inadequate. The amendment exempts the newer WACO YMF-F5 and YMF-F5C series aircraft from the requirement to use CASA's maintenance schedule, recognising that their comprehensive maintenance manuals, including the YMFAMM-1 and Jacobs Aircraft Engine Operators Manual (R-755A, B & S), are adequate for ensuring the safety of air navigation. This amendment is limited to the geographic jurisdiction of Australia and applies to all aircraft registered under the Australian Register. The Civil Aviation Order 100.5 Amendment Instrument 2013 (No. 3) is a legislative instrument subject to the Legislative Instruments Act 2003, which mandates its registration, tabling, and potential disallowance in the Parliament. The amendment has undergone consultation and has been deemed minor by the Office of Best Practice Regulation, thus not requiring a Regulation Impact Statement. Furthermore, a Statement of Compatibility with Human Rights has been prepared, affirming that the amendment does not engage any rights or freedoms recognised in the Human Rights (Parliamentary Scrutiny) Act 2011, thereby confirming its compatibility with human rights. The amendment commenced on the day of its registration and is enforced by CASA to ensure compliance with aviation safety standards.

Key Provisions

The main operative sections of this legislation are found in the Civil Aviation Order 100.5 Amendment Instrument 2013 (No. 3), which amends the existing Civil Aviation Order 100.5 (CAO 100.5). Specifically, this instrument modifies paragraph 8.1 of CAO 100.5 to exclude WACO Classic Aircraft Corporation YMF-F5 and YMF-F5C series aircraft that have FAA supplemental type certificate SA1000GL incorporated at manufacture from the list of aircraft whose manufacturers’ maintenance schedules have been declared inadequate by the Civil Aviation Safety Authority (CASA). This means that the maintenance schedules for these particular aircraft, which include comprehensive modern manuals, can now be used as their maintenance schedules, unlike the original WACO aircraft from the 1930s. The change aims to differentiate between the older WACO aircraft and the newer, more modern versions, recognising the adequacy of the latter's maintenance schedules. The obligations imposed by this Act on the parties or entities it governs include the requirement for registered operators of the specified WACO YMF-F5 and YMF-F5C series aircraft to now use the manufacturer’s maintenance schedules as outlined in the updated CAO 100.5. This is a significant shift from the previous requirement that these operators use the CASA maintenance schedule instead. The updated maintenance schedules must be followed meticulously to ensure that the safety standards set by CASA are maintained. Operators must also ensure that all personnel involved in the maintenance of these aircraft are adequately trained and familiar with the updated maintenance schedules and manuals. There are no specific offences, penalties, or civil/criminal consequences outlined in this particular CAO amendment. However, it is implied that failure to adhere to the newly approved maintenance schedules could lead to potential safety issues, which may result in CASA taking enforcement actions against non-compliant operators. Such actions could include grounding of the aircraft, suspension of operations, or other regulatory measures to ensure compliance with aviation safety standards. The overarching principle remains that any breach of the safety regulations could lead to severe consequences for both the operators and the safety of the flying public.
