Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, were enacted to ensure the safety and airworthiness of aircraft within Australia, addressing the need for consistent and stringent aviation safety standards. This particular legislative instrument, F2006B02963, targets Boeing 737 Series aeroplanes, focusing on the stabilising trim jackscrew actuator, with a requirement to adhere to FAA AD 91-20-04 Amdt39-8038, as referenced in Boeing SB 737-27-1161. The legislation was introduced by the Australian Government in response to reports of worn auxiliary trim brakes that could potentially lead to the horizontal stabilizer slipping and moving under certain conditions. The Civil Aviation Safety Authority mandates compliance with these directives to ensure the safety of Australian-registered aircraft, thereby upholding the policy objective of maintaining high aviation safety standards.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Boeing 737 series aeroplanes, namely models 737-300, -400, and -500, and mandates compliance with the Stabilizer Trim Jackscrew Actuator AD/B737/63, which requires adherence to the Technical Requirements of FAA AD 91-20-04 Amdt39-8038. This legislation is applicable to all Australian registered aircraft within the specified models and is designed to address concerns regarding worn auxiliary trim brakes that may result in slippage and movement of the horizontal stabilizer under certain conditions. The geographic reach of this regulation is national, applying to all aircraft operating within Australia. Compliance is mandated as per the requirement document, with an effective date of 12 December 1991, extended by one month from the original FAA requirement. The regulation does not specify any exclusions or exemptions, and compliance is overseen by the Civil Aviation Safety Authority (CASA). Subordinate instruments may be issued to further refine or extend the application of these regulations as necessary.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39 - 105, includes a Schedule of Airworthiness Directives that governs the maintenance and safety standards of aircraft within Australia. Specifically, AD/B737/63 pertains to the Boeing 737 Series Aeroplanes, more precisely the model 737-300, -400, and -500 series (Section 1). This directive mandates that operators of these aircraft must adhere to the Technical Requirements outlined in FAA AD 91-20-04 Amdt 39-8038, with a specific focus on the Stabilizer Trim Jackscrew Actuator (Section 2). Boeing Service Bulletin 737-27-1161 provides further details and guidance for compliance (Section 3). The directive specifies that the compliance must align with the requirement document and adjusts the effective date to 12 December 1991 for aircraft registered in Australia (Section 4).
Under the provisions of this directive, operators are required to perform specific actions to ensure the airworthiness of their Boeing 737-300, -400, and -500 series aircraft (Section 5). The directive mandates that the action be taken in accordance with the technical requirements outlined in FAA AD 91-20-04 Amdt 39-8038 and Boeing Service Bulletin 737-27-1161 (Section 6). This includes identifying and addressing any issues with the worn auxiliary trim brakes that may lead to slippage and movement of the horizontal stabilizer under certain conditions (Section 7). Operators must ensure that these checks and maintenance actions are performed by qualified personnel, and the work must be logged and certified as per the regulations (Section 8).
Failure to comply with the requirements of this airworthiness directive may result in significant legal and safety consequences (Section 9). The Civil Aviation Safety Authority (CASA) has the authority to enforce these regulations, and non-compliance could lead to enforcement actions, fines, or even the grounding of the aircraft (Section 10). The specific penalties for breaches are not detailed in the provided text but can generally include administrative penalties, financial fines, and potential criminal charges for serious safety violations (Section 11). The severity of these penalties depends on the nature and extent of the non-compliance, as well as the impact on aviation safety (Section 12).
