Overview
The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), include specific provisions to ensure the safety and airworthiness of aircraft operating within Australia. One such provision is contained within Part 39 - 105 of the Civil Aviation Regulations 1998, which mandates Airworthiness Directives (ADs) for various aircraft types, including the Aerospatiale (Socata) TB20 (Trinidad) Series Aeroplanes. This particular directive, AD/TB20/15 Amendment 2, was introduced to address a critical safety issue concerning the landing gear articulated stays of the TB20 and TB21 series aircraft with specific serial numbers. The objective of this AD is to prevent the landing gear from jamming, thereby enhancing flight safety and compliance with international safety standards. This directive requires action in accordance with the technical requirements set forth in the DGAC AD 89-096 (A) R2 and necessitates compliance by ensuring the landing gear is modified as per specified service intervals or upon exceeding certain flight hours.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to Aerospatiale (Socata) TB20 (Trinidad) Series Aeroplanes with the serial numbers ranging from 275 through 1119, excluding serial number 1109. This regulation governs the airworthiness directives that must be adhered to by the operators of these aircraft. The geographic reach of this legislation is national, applying across the Commonwealth of Australia and overseen by the Civil Aviation Safety Authority (CASA). The directive requires that action be taken in accordance with the technical requirements of DGAC AD 89-096 (A) R2, referencing Socata TB Service Bulletins 40 and 45/2, which provide the necessary compliance guidelines to prevent landing gear jamming. Operators must ensure that the specified actions are completed before the aircraft exceeds 100 hours of time in service after 22 March 1990, and subsequently at intervals not exceeding 500 hours of time in service or 1 year, whichever comes first, until the modifications as per Service Bulletins 45/1 or 45/2 are implemented. The regulation extends its application through amendments, with Amendment 2 referencing the latest Requirement Documents and Service Bulletins.
Key Provisions
The Civil Aviation Regulations 1998, under PART 39 - 105 and specifically within the schedule of airworthiness directives, detail critical safety requirements for the Aerospatiale (Socata) TB20 (Trinidad) Series Aeroplanes. The regulation AD/TB20/15 Amendment 2 focuses on the landing gear articulated stays. According to section (3/91), the applicability of this directive is limited to the TB20 and TB21 series aeroplanes with serial numbers ranging from 275 through 1119, with the exception of serial number 1109. The primary requirement, as outlined in section (Requirement), is to follow the technical specifications of DGAC AD 89-096 (A) R2. The note refers to Socata TB Service Bulletins (SB) 40 and 45/2, which provide further guidance. Compliance with this directive requires action to be taken unless it has already been accomplished. Specifically, the action must be completed before the aircraft exceeds 100 hours of time in service after 22 March 1990, and then at intervals not exceeding 500 hours of time in service, or 1 year, whichever comes first, until the aircraft is modified in accordance with SB 45/1 or 45/2.
The obligations imposed by this directive on the operators and maintainers of the affected aircraft are clear and precise. They must ensure that the landing gear articulated stays are modified or inspected in accordance with the specified schedule to prevent the risk of the landing gear jamming. This involves adhering to the technical requirements outlined in the referenced DGAC AD 89-096 (A) R2 and the Socata TB Service Bulletins. Operators and maintainers need to meticulously track the aircraft's time in service to comply with the stipulated intervals for compliance checks. The installation of the kits listed in SB 45/1 or 9166, as mentioned in SB 45/2, is crucial for terminating the directive requirements if such modifications are carried out.
Failure to comply with the provisions of this airworthiness directive can result in significant legal and operational consequences. Although the specific penalties are not detailed within the text, it is understood that non-compliance with airworthiness directives in Australia can lead to serious civil and criminal repercussions. These may include fines, grounding of the aircraft, or even prosecution under the Civil Aviation Act 1988. The penalties can be severe, as the safety of the aircraft and its occupants is paramount, and any breach of these safety regulations is taken very seriously by the Civil Aviation Safety Authority (CASA). The exact penalties would depend on the nature and severity of the breach, as well as any subsequent impact on flight safety.
