AD/SWSA226/9 - Main Landing Gear Uplock Roller - Inspection and Modification

Overview

The Civil Aviation Regulations 1998 were enacted to provide a regulatory framework for civil aviation in Australia, addressing the need for a cohesive and enforceable set of rules governing airworthiness, licensing, and safety standards. These regulations, administered by the Civil Aviation Safety Authority (CASA), aim to ensure the safety and efficiency of civil aviation operations within Australia's airspace. One of the key components of these regulations is the Schedule of Airworthiness Directives, which includes specific safety directives for various aircraft types, such as the Fairchild (Swearingen) SA226 and SA227 Series Aeroplanes. The purpose of these directives is to ensure that aircraft meet minimum safety standards, thereby reducing the risk of accidents and enhancing overall aviation safety. A specific example of such a directive is AD/SWSA226/9, which pertains to the main landing gear uplock roller of the Fairchild (Swearingen) SA226 and SA227 Series Aeroplanes with serial numbers between T201 and T220. This directive mandates an inspection and possible modification of the uplock roller to ensure its proper functioning and reliability. Compliance with this directive is required within 100 hours of time in service after 28 February 1973, as documented in Swearingen SB 30-10-3028. The overarching policy objective of such directives is to maintain high safety standards and to ensure the continued airworthiness of aircraft operating within Australia's jurisdiction.

Scope and Application

The Civil Aviation Regulations 1998, under the scope of Part 39 - 105, specifically address the requirements for airworthiness directives concerning various aircraft models. This particular regulation pertains to the Fairchild (Swearingen) SA226 and SA227 series aeroplanes, specifically those with serial numbers T201 to T220. The directive mandates an inspection and possible modification of the main landing gear uplock roller, with compliance expected within 100 hours of time in service after 28 February 1973, as documented in Swearingen SB 30-10-3028. This regulation applies to any person or entity operating these specific aircraft models within Australian airspace, ensuring that the required modifications are adhered to in order to maintain the safety and airworthiness standards set forth by the Civil Aviation Safety Authority (CASA). The directive's jurisdictional reach is nationwide, extending to all operators within the Commonwealth of Australia. No specific exclusions or exemptions are mentioned in the provided text, indicating that all relevant operators must comply with the directive.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate that all Fairchild (Swearingen) SA226 and SA227 series aeroplanes with serial numbers (S/Nos.) T201 to T220 undergo an inspection and modification of the main landing gear uplock roller. This is outlined in AD/SWSA226/9. According to section (2/73), this directive applies to aircraft that have accumulated 100 hours of time in service since 28 February 1973. The compliance is to be carried out in accordance with the Swearingen SB 30-10-3028 document, which specifies the technical details and procedures necessary for the inspection and modification. The obligations imposed by this legislation are clear and specific. Owners or operators of the affected aircraft must ensure that the inspection and modification of the main landing gear uplock roller is performed by certified personnel using the specified document as a guide. This requirement ensures that the aircraft's landing gear operates correctly, thereby enhancing safety during flight operations. The regulations necessitate that all modifications are logged and documented, providing a traceable record of compliance. Failure to comply with the directives set out in AD/SWSA226/9 can result in significant legal and financial repercussions. Under the Civil Aviation Regulations 1998, non-compliance with airworthiness directives can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). This may include fines, suspension or revocation of airworthiness certificates, and potential criminal charges against responsible individuals. The maximum penalties for such offences can be substantial, reflecting the seriousness with which aviation safety regulations are taken. It is essential for all parties involved to adhere strictly to these provisions to avoid any adverse consequences.
