COMMONWEALTH OF AUSTRALIA (Civil Aviation Safety Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AIRWORTHINESS DIRECTIVE
For the reasons set out in the background section, the CASA delegate whose signature appears below issues the following Airworthiness Directive (AD) under subregulation 39.1 (1) of CASR 1998. The AD requires that the action set out in the requirement section (being action that the delegate considers necessary to correct the unsafe condition) be taken in relation to the aircraft or aeronautical product mentioned in the applicability section: (a) in the circumstances mentioned in the requirement section; and (b) in accordance with the instructions set out in the requirement section; and (c) at the time mentioned in the compliance section.
Aerospatiale (Socata) TBM 700 Series Aeroplanes
AD/TBM 700/37 Engine Controls - Propeller and
Fuel Control Cables
13/2004
DM
Applicability: EADS SOCATA TBM 700 aircraft Serial Number (S/N) 285 to 304 and S/N 307. Requirement: 1. Comply with the operational procedures detailed in paragraph A of
Accomplishment Instructions of EADS SOCATA Alert Service Bulletin (ASB)
No. 70-123 or later DGAC approved revisions.
2. Check the batch number identified on the control cables and carry out replacement of the cables as necessary as detailed in paragraph B of the Accomplishment Instructions EADS SOCATA ASB No. 70-123.
Note: DGAC AD UF-2004-175 EASA approval number 2004-10823 dated 27 October 2004 refers.
Compliance: For Requirement 1: Prior to the next flight after the effective date of this Directive. For Requirement 2: Within 25 flight hours after the effective date of this Directive. This Airworthiness Directive becomes effective on 10 November 2004.
Background: The manufacturer has advised that there have been failures of control cables due to incorrect crimping during manufacture. A failure in the crimp could lead to a reduction in the propeller RPM during flight.
James Coyne
Delegate of the Civil Aviation Safety Authority 29 October 2004
The above AD is notified in the Commonwealth of Australia Gazette on 10 November 2004.

Overview
The Civil Aviation Safety Regulations 1998 (CASR) were enacted to establish and regulate the standards of airworthiness and safety for all aircraft within Australian airspace. The problem or gap addressed by these regulations includes ensuring the safety and airworthiness of aircraft and aeronautical products, and providing a legal framework for the Civil Aviation Safety Authority (CASA) to implement and enforce airworthiness directives when safety issues are identified. The enactment of this legislation by the Australian Parliament aimed to protect public safety and ensure that aviation operations within Australia adhere to stringent safety standards. As indicated in the text, the policy objective of the Civil Aviation Safety Regulations is to ensure the highest levels of safety in civil aviation by providing a robust framework for the regulation and oversight of airworthiness and safety measures.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, addresses airworthiness directives issued by the Civil Aviation Safety Authority (CASA) to ensure the safety of aircraft and aeronautical products. One such directive, AD/TBM 700/37, pertains to Aerospatiale (Socata) TBM 700 series aeroplanes, specifically those with serial numbers 285 to 304 and 307. This directive mandates adherence to certain operational procedures and replacement of control cables to mitigate risks associated with cable failures due to manufacturing defects. Compliance with this directive is mandatory for the specified serial numbers and must be carried out by the next flight for the operational procedures and within 25 flight hours for the cable replacement, as outlined in the directive. The directive is applicable throughout the Commonwealth of Australia, ensuring a uniform safety standard across the country. The authority to extend or modify the application of such directives may be exercised through subordinate instruments, maintaining the flexibility to respond to emerging safety concerns.
Key Provisions
The Civil Aviation Safety Regulations 1998, Part 39, specifically Section 105, mandates that the Civil Aviation Safety Authority (CASA) issues Airworthiness Directives (AD) to ensure the safety of aircraft. An example of such an AD is AD/TBM 700/37, which applies to Aerospatiale (Socata) TBM 700 Series Aeroplanes with specific serial numbers. This directive requires compliance with operational procedures outlined in EADS SOCATA Alert Service Bulletin No. 70-123 or subsequent revisions approved by the DGAC. Moreover, it mandates a check on the batch number of the control cables and the replacement of these cables as necessary, following the instructions in paragraph B of the Accomplishment Instructions of the aforementioned bulletin.
The obligations imposed by this AD on the relevant parties include ensuring adherence to the detailed operational procedures and timely replacement of the control cables. Specifically, Requirement 1 must be complied with before the next flight after the directive's effective date, while Requirement 2, concerning the replacement of the cables, must be completed within 25 flight hours following the directive's effective date. Failure to comply with these obligations may lead to safety risks, including potential propeller RPM reduction during flight, which could compromise the aircraft's safe operation.
The AD imposes clear penalties and consequences for non-compliance. Operators who fail to adhere to the requirements set forth in this directive may face severe repercussions. Non-compliance could result in the aircraft being deemed unairworthy, leading to grounding and potential legal action. Additionally, CASA may impose fines and other penalties on operators who do not comply with the AD, underscoring the critical importance of adhering to the specified safety measures. The maximum penalties for such breaches are not explicitly stated in the AD but could include substantial financial penalties and other enforcement actions under the Civil Aviation Act 1988 and the Civil Aviation Regulations 1988.
