Explanatory Statement

 

Civil Aviation Safety Regulations 1998

 

AD/LTS/9 Amdt 3 — Number 3 and 4 Bearing Monitoring

 

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 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. When a foreign State of Design issued an AD before 1 October 2009 for a type of aircraft on the Australian Register, CASA, as Australia’s national airworthiness authority, must assess that information and, if appropriate, issue an Australian AD to mandate the requirements of the foreign State of Design. AD/LTS/9 Amdt 3 applies to Honeywell LTS101 series engines.

 

The United States of America Federal Aviation Administration (FAA) issued AD 88‑14‑01 affecting Honeywell LTS101 series engines in 1988. The United States of America is the State of Design for this engine type. CASA subsequently issued AD/LTS/9 Amdt 2 to mandate the requirements of FAA AD 88-14-01. As a result of a request from industry, CASA has issued AD/LTS/9 Amdt 3 to allow the use of Honeywell Service Bulletin LT 101-72-50-0227 as a means of compliance to address the unsafe condition identified in FAA AD 88-14-01. This AD repeals and replaces the previous AD on this subject.

 

Consultation

This AD is being made at the request of industry, in particular an operator of aircraft fitted with Honeywell LTS101 series engines. As this AD is of a minor or machinery nature and does not substantially alter existing arrangements apart from providing an alternate means of compliance, 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 instrument 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 August 2014.

Overview of the legislative instrument

The United States of America Federal Aviation Administration (FAA) issued AD 88‑14‑01 affecting Honeywell LTS101 series engines in 1988. The United States of America is the State of Design for this aircraft type. CASA subsequently issued AD/LTS/9 Amdt 2 to mandate the requirements of FAA AD 88-14-01. As a result of a request from industry, CASA has repealed and replaced AD/LTS/9 Amdt 2 to allow the use of a Honeywell Service Bulletin as a means of compliance to address the unsafe condition identified in FAA AD 88-14-01.

 

The primary purpose of this legislative instrument is to provide an alternate means of compliance to the requirements of the earlier CASA AD.

 

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 Safety Regulations 1998 were enacted to ensure the safety of air navigation in Australia. Under the Civil Aviation Act 1988, the Governor-General has the power to make regulations for the Act, and the Civil Aviation Safety Authority (CASA) can issue airworthiness directives (ADs) for types of aircraft or aeronautical products. This legislative instrument, AD/LTS/9 Amdt 3, was introduced in response to a request from industry, specifically an operator of aircraft fitted with Honeywell LTS101 series engines. This AD allows for an alternate means of compliance to address an unsafe condition identified in an earlier FAA AD. It repeals and replaces AD/LTS/9 Amdt 2, which had previously mandated the requirements of FAA AD 88-14-01. The policy objective is to ensure the continuing airworthiness of aircraft on the Australian Register by providing necessary information and requirements for compliance. This AD was made by a delegate of CASA, relying on the power of delegation under the Civil Aviation Safety Regulations 1998 and the Civil Aviation Act 1988.

Scope and Application

The AD/LTS/9 Amdt 3 — Number 3 and 4 Bearing Monitoring applies to the Honeywell LTS101 series engines, which are a type of aircraft engine designed by the United States of America, the State of Design. This legislation, made under the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998, is intended to ensure the safety of air navigation by mandating compliance with specific maintenance requirements for these engines. The amendment, which replaces an earlier directive, allows the use of a Honeywell Service Bulletin as an alternative means of compliance to address a previously identified unsafe condition. This legislative instrument is applicable across Australia and aligns with international standards as set out in Annex 8 to the Convention on International Civil Aviation. It is important to note that this directive does not substantially alter existing arrangements and was made without the need for further consultation or a Regulation Impact Statement. The AD/LTS/9 Amdt 3 is compatible with human rights, as confirmed by a Statement of Compatibility with Human Rights, and it was issued by the Civil Aviation Safety Authority (CASA) as Australia's national airworthiness authority.

Key Provisions

The Civil Aviation Safety Regulations 1998 (CASR 1998) are amended by AD/LTS/9 Amdt 3 to address the monitoring of number 3 and 4 bearings in Honeywell LTS101 series engines. The primary change introduced by this amendment is the allowance for compliance with the unsafe condition identified in FAA AD 88-14-01 through the use of Honeywell Service Bulletin LT 101-72-50-0227 (section 1). This amendment repeals and replaces the previous AD/LTS/9 Amdt 2, which had mandated the requirements of the FAA AD directly. The Civil Aviation Safety Authority (CASA) is required to ensure that operators of aircraft fitted with Honeywell LTS101 series engines comply with the specified monitoring and maintenance procedures. This includes conducting the necessary inspections and maintenance actions as detailed in the Honeywell Service Bulletin to ensure the continuing airworthiness of these engines (regulation 39.001). Operators must maintain records of all inspections and actions taken in accordance with the AD and the Service Bulletin, and provide these records to CASA upon request (section 3). Breaches of the AD requirements can result in serious consequences. CASA has the authority to take enforcement actions, including issuing compliance notices, conducting investigations, and imposing fines. The maximum penalty for non-compliance with a CASA AD is a fine of up to $1,215,000 for a corporation and up to $243,000 for an individual, reflecting the seriousness of ensuring aviation safety (subsection 98(5B) of the Civil Aviation Act 1988). In addition to financial penalties, non-compliance can also lead to the grounding of affected aircraft until the necessary corrective actions are completed. This ensures that any potential safety risks are mitigated promptly. AD/LTS/9 Amdt 3 is a legislative instrument issued under the authority of the Civil Aviation Act 1988 and the Civil Aviation Safety Regulations 1998. It has been made to address an identified safety issue with the Honeywell LTS101 series engines and to provide operators with an alternative means of compliance. The amendment was made following consultation with industry stakeholders and is considered to be of a minor nature, which is why further consultation under the Legislative Instruments Act 2003 was deemed unnecessary. The AD commenced on 1 August 2014 and CASA has ensured that the legislative instrument is compatible with human rights, as outlined in the Statement of Compatibility with Human Rights.
