AD/SWSA226/60 - Stall Avoidance System Maintenance

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the maintenance and operational safety of civil aircraft in Australia. This regulation was enacted by the Parliament of Australia to ensure the safe operation of aircraft, particularly in response to identified safety issues and to comply with international standards set by the International Civil Aviation Organization (ICAO). One such regulation within this part is the Airworthiness Directive AD/SWSA226/60 concerning the Fairchild (Swearingen) SA226 and SA227 series aeroplanes. This directive was introduced to address the specific issue of the stall avoidance system in these aircraft models, ensuring that these aircraft maintain their airworthiness by adhering to the requirements outlined in the Federal Aviation Administration’s Airworthiness Directive 85-22-06 R1. The overarching policy objective is to maintain the highest standards of aviation safety and to prevent incidents related to the malfunction of critical systems such as the stall avoidance system. The regulations mandate that all applicable models must undergo inspection and necessary modifications as stipulated in the requirement document within 100 hours of time in service from the directive's effective date of 24 January 1991. This directive aims to assure the proper operation of the stall avoidance system, thereby contributing to the overall safety of civil aviation operations within Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, with a focus on the Fairchild (Swearingen) SA226 and SA227 Series Aeroplanes. This regulation applies to all models of these aircraft as outlined in the associated Requirement Document. Its purpose is to ensure the proper operation of the Stall Avoidance System through mandated inspections and modifications as detailed in FAA Airworthiness Directive 85-22-06 R1. Operators and owners of these aircraft must comply with the requirements within 100 hours of time in service from the directive's issue date of 24 January 1991. The geographic reach of this legislation is national, as it pertains to all civil aviation activities within Australia, ensuring uniformity in air safety standards across the country. This legislation does not specify any exclusions, exemptions, or thresholds, implying that it applies universally to the specified aircraft models. While the primary text of the regulation outlines the specific requirements and compliance timeframes, the application and interpretation of these directives can be further detailed through subordinate instruments, which may provide additional operational guidelines or clarifications to ensure consistent enforcement and adherence to safety standards.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), specifically Part 39, Section 105, addresses the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for Fairchild (Swearingen) SA226 and SA227 series aeroplanes. The directive AD/SWSA226/60 mandates that the Stall Avoidance System on these aircraft must be inspected and/or modified as appropriate, in accordance with the Federal Aviation Administration (FAA) Airworthiness Directive 85-22-06 R1. This requirement is critical to ensure the proper operation of the Stall Avoidance System and must be carried out within 100 hours of time in service from the directive's effective date of 24 January 1991. The obligations imposed by this directive are clear and specific. Operators of the affected aircraft models must adhere to the inspection and modification requirements outlined in FAA Airworthiness Directive 85-22-06 R1. This includes conducting the necessary inspections and making any required modifications to the Stall Avoidance System within the specified timeframe. Failure to comply with these obligations can lead to serious safety issues, as the Stall Avoidance System plays a crucial role in preventing stalls and ensuring the safe operation of the aircraft. In terms of enforcement, non-compliance with the provisions of this airworthiness directive can result in significant consequences. While the specific civil or criminal penalties are not detailed in the extract provided, it is understood that CASA has the authority to enforce compliance through various means, including fines, operational restrictions, or other regulatory actions. The severity of the penalties may depend on the nature and extent of the non-compliance, as well as any resulting safety implications. Given the importance of the Stall Avoidance System in maintaining aircraft safety, any breach of this directive could potentially lead to severe penalties and significant safety risks.
