AD/SF340/16 - AC Generator P/N 31342-001

Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, establish the authority and requirements for the Civil Aviation Safety Authority to issue airworthiness directives, aiming to enhance the safety of civil aviation operations. This legislative instrument, F2006B06944, targets SAAB SF340 Series aeroplanes with an aim to address safety concerns related to the AC generator P/N 31342-001. The directive mandates the removal from service of generators that have not been modified to “Mod D” standards due to their unacceptable failure rate, thereby ensuring the reliability and safety of aircraft in operation. This directive is enacted by the Australian Government and aligns with the overarching policy objective of maintaining high safety standards within the civil aviation sector. The regulatory framework provided by the Civil Aviation Regulations 1998 ensures that all stakeholders, including aircraft operators and maintenance providers, are aware of and comply with these critical safety requirements, thus protecting both public and crew safety. The directive reflects a proactive approach to mitigating risks associated with specific components within the SAAB 340A aircraft fleet, ensuring adherence to safety standards and preventing potential in-flight failures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for Saab SF340 series aeroplanes, particularly concerning AC generator P/N 31342-001. This legislation applies to all Saab 340A aircraft equipped with an AC generator P/N 31342-001 that have not been modified to meet the “Mod D” standard. The directive mandates the removal of such generators from service, aiming to address the unacceptable fail rate observed in the unmodified units. Compliance with this directive is required before 10 May 1990, and it is reinforced by references to SAD 1-033 and Saab-Scania AB Service Bulletin SF340-24-016, ensuring that all relevant operators and maintenance providers are informed of the necessary safety measures. The regulations extend nationally, applying to all entities operating within the Australian Commonwealth that fall under CASA’s jurisdiction, with no specific exclusions outlined in this directive.

Key Provisions

The primary sections of the Civil Aviation Regulations 1998 (section 105) mandate the removal from service of specific SAAB 340A aircraft generators (section AD/SF340/16) that have not been modified to the "Mod D" standard. This requirement applies to all SAAB 340A aircraft equipped with AC generator P/N 31342-001 that have not undergone the necessary modifications. Compliance with this directive is mandatory, and the action must be taken before 10 May 1990. The Act imposes specific obligations on the operators and owners of SAAB 340A aircraft to ensure that any AC generator P/N 31342-001 on their aircraft is either modified to the "Mod D" standard or removed from service entirely. Operators must verify the modification status of the generators on their aircraft and take appropriate action if the generators have not been modified. This obligation extends to conducting any necessary modifications or removals to comply with the directive. Failure to comply with these requirements can result in significant legal consequences. The Civil Aviation Safety Authority has the authority to enforce compliance with Airworthiness Directives, and non-compliance may lead to enforcement actions. The specific penalties for non-compliance are not detailed within the directive, but they can include fines, operational restrictions, or other regulatory actions as deemed appropriate by the Civil Aviation Safety Authority. Additionally, failure to adhere to these safety directives could potentially lead to aircraft being grounded or deemed airworthy, which could have serious implications for both the operator and passengers.
