Overview
The Civil Aviation Regulations 1998, enacted by the Commonwealth Parliament, aim to ensure the safety and efficiency of civil aviation in Australia. The legislation addresses the need for a comprehensive regulatory framework governing all aspects of civil aviation operations within the country. One particular focus of this Act is the establishment of airworthiness standards, including the issuance of airworthiness directives to mitigate safety risks associated with specific aircraft models. The policy objective is to maintain and enhance the safety standards of civil aviation by proactively addressing potential safety issues through regulatory measures.
The Civil Aviation Regulations 1998 include a specific airworthiness directive concerning Schweizer (Hughes) 269 Series Helicopters, as detailed in AD/HU 269/41. This directive mandates an inspection of the main rotor thrust bearing (P/N 269A5050-73) for runout on all models incorporating Kit No. M10044. This requirement applies to aircraft with a specific Serial Identification Number (SIN) and must be completed within 200 hours of time in service after 29 October 1971, or if the kit was installed after this date. The directive is designed to ensure the continued safe operation of these helicopters by addressing a known safety issue related to the main rotor thrust bearing.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all Schweizer (Hughes) 269 Series Helicopters incorporating Kit No. M10044, which is identified by Serial Identification Number (SIN) N-76.2. This regulatory framework is established and enforced by the Civil Aviation Safety Authority (CASA) under the Commonwealth of Australia. The legislation mandates compliance with Airworthiness Directives (AD), such as AD/HU 269/41, which requires an inspection for runout of the main rotor thrust bearing part number 269A5050-73. This inspection must be conducted within 200 hours of time in service following 29 October 1971, or if the inspection was not performed during or after the installation of Kit No. M10044 as per Hughes SIN No. N-94. The legislation is applicable nationwide, covering all relevant operators and entities within the Australian jurisdiction, and does not explicitly exclude any specific persons or entities from its scope. Subordinate instruments may further detail or modify the application of these directives as necessary.
Key Provisions
The key operative sections of the Civil Aviation Regulations 1998, specifically the AD/HU 269/41 directive, require an inspection for runout of the main rotor thrust bearing (P/N 269A5050-73) on Schweizer (Hughes) 269 Series Helicopters. This inspection is mandated for all models that incorporate Kit No. M10044 with Serial Identification Number (SIN) No. N-76.2. The requirement is for this inspection to be completed within 200 hours of time in service after 29 October 1971, or if this inspection was not previously performed during or following the installation of Kit No. M10044 (section 39.105).
These regulations impose specific obligations on the operators and owners of Schweizer (Hughes) 269 Series Helicopters. They must ensure that the main rotor thrust bearing is inspected for runout as specified in the directive. This inspection must be conducted by a qualified individual who is authorised to perform such inspections under the Civil Aviation Safety Authority (CASA) regulations. The compliance must be documented and recorded appropriately to demonstrate adherence to the directive.
Failure to comply with the AD/HU 269/41 directive can result in serious consequences. Non-compliance with airworthiness directives is a significant breach of safety regulations. Under the Civil Aviation Act 1988, operators and owners who fail to comply with these directives may face enforcement actions, including fines, sanctions, and potential grounding of the aircraft. The severity of the penalties may depend on the circumstances of the non-compliance, but the potential for significant financial penalties and operational restrictions underscores the importance of adhering to these safety requirements.
