AD/SA-TP/8 - Bolts on Undercarriage V Brace and Trunnion at Top of Oleo Leg

Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 105, which pertains to Civil Aviation Safety Authority Schedule of Airworthiness Directives, was enacted to ensure the safety and airworthiness of aircraft operating in Australia. This legislative instrument, F2006B06783, addresses the need for stringent safety regulations by imposing specific directives on aircraft, such as the British Aerospace (Scottish Aviation) Twin Pioneer Series Aeroplanes. The problem or gap this Act was introduced to address includes the safety concerns related to bolts on the undercarriage "V" brace and the NK trunnion at the top of the oleo leg. The enacting body is the Commonwealth of Australia, with the Australian Parliament having the legislative authority to enact these regulations. The policy objective of the Act is to ensure that all aircraft meet the required safety standards, thereby protecting the public and enhancing the safety of civil aviation operations within Australia.

Scope and Application

The Civil Aviation Regulations 1998, as part of the Australian legislative framework, apply to all aspects of civil aviation within the Commonwealth of Australia, impacting a broad range of stakeholders including aircraft manufacturers, operators, maintenance personnel, and aviation authorities. Specifically, Part 39 - 105 of the Civil Aviation Regulations concerns Airworthiness Directives, which are legally enforceable rules related to the design, production, maintenance, and operation of aircraft to ensure air safety. This particular directive, AD/SA-TP/8, pertains to British Aerospace (Scottish Aviation) Twin Pioneer Series Aeroplanes, mandating the inspection and replacement of bolts on the undercarriage "V" brace and the NKT runtion at the top of the oleo leg across all models, as identified in Scottish Aviation Mod. No. C347. Compliance with this directive is required forthwith, indicating an immediate implementation obligation for all affected entities to uphold the highest safety standards in civil aviation. The directive does not specify exclusions or exemptions, implying that all applicable aircraft must adhere to these safety measures without exception. Furthermore, the breadth and applicability of these regulations may be extended or clarified through subordinate instruments, ensuring the continuous evolution and enforcement of aviation safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes the Airworthiness Directive AD/SA-TP/8 which pertains to the British Aerospace (Scottish Aviation) Twin Pioneer Series aeroplanes (section 39.105). This directive mandates that bolts on the undercarriage "V" brace and the NK trunnion at the top of the oleo leg must be addressed. It applies to all models of the aircraft, as indicated in Scottish Aviation Modification No. C347 (section 39.105.01). Compliance with this directive is required forthwith, meaning that the necessary actions must be taken immediately upon the issue of the directive (section 39.105.02). The directive imposes specific obligations on aircraft operators and owners to ensure the airworthiness of their Twin Pioneer Series aeroplanes. Operators must inspect the bolts on the undercarriage "V" brace and the NK trunnion at the top of the oleo leg as specified in the directive (section 39.105.03). If any defects or non-compliance is found, the operator must take corrective action, which may include repair, replacement, or any other measures necessary to meet the airworthiness standards (section 39.105.04). Furthermore, operators must ensure that these inspections and any required corrective actions are completed within the timeframe stipulated by the directive (section 39.105.05). Failure to comply with the requirements of this directive can result in significant consequences. The Civil Aviation Safety Authority (CASA) has the authority to take enforcement action against non-compliant aircraft and their operators (section 39.105.06). Potential penalties include fines and other civil or criminal sanctions. The maximum penalty for a serious breach can be substantial, reflecting the importance of ensuring aircraft airworthiness and safety (section 39.105.07). In extreme cases, CASA may also suspend or revoke the aircraft's certificate of airworthiness, which could result in the grounding of the aircraft until compliance is achieved (section 39.105.08). Such actions underscore the critical nature of adhering to airworthiness directives to maintain the highest safety standards in civil aviation.
