AD/AC-100/12 - Exhaust Muffler - Modification

Overview

The Civil Aviation Regulations 1998, as amended by the legislative instrument F2006B02164, were enacted to provide a comprehensive regulatory framework ensuring the safety and efficiency of civil aviation in Australia. This legislation was introduced by the Commonwealth of Australia and was intended to address gaps in aviation safety regulation, particularly in relation to specific aircraft models. The policy objective of this Act, as highlighted in the legislative instrument, is to mandate modifications to exhaust mufflers for certain Commander 100 Series and Volair 10 Series aeroplanes, ensuring they comply with airworthiness standards set forth by the Civil Aviation Safety Authority (CASA). The regulation applies to models 100 and 100-180, requiring compliance within 100 hours of service following the directive issued on 30 March 1973, as referenced in Aero Commander Service Bulletin 1019 or FAA AD 73-1-1.

Scope and Application

The Civil Aviation Regulations 1998, as amended, under Part 39, specifically target the maintenance and airworthiness of aircraft, including the S.L. Industries Commander 100 Series and Volair 10 Series aeroplanes, with a focus on the exhaust muffler modification as outlined in AD/AC-100/12. This regulation applies to the aircraft models 100 and 100-180 and mandates compliance through modifications as specified in the Aero Commander Service Bulletin 1019 or the FAA AD 73-1-1. The directive requires these modifications to be completed within 100 hours of the aircraft's time in service following 30 March 1973, ensuring that the aircraft meet the prescribed safety standards. The application of these regulations extends to any person or entity involved in the operation or maintenance of these aircraft within Australian airspace, thereby ensuring the safety and compliance of civil aviation operations under the oversight of the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39, Section 105, includes detailed provisions regarding the airworthiness directives for certain aircraft models. For instance, the regulation AD/AC-100/12 pertains to the S.L. Industries Commander 100 Series and Volair 10 Series aeroplanes, focusing on exhaust muffler modifications (Section 105(1)). The applicability of this directive is limited to Models 100 and 100-180, as delineated in the compliance document (Section 105(2)). Compliance with this directive requires modifying the exhaust muffler within 100 hours of time in service after 30 March 1973 (Section 105(3)). The compliance documentation required includes either Aero Commander SB 1019 or FAA AD 73-1-1 (Section 105(4)). Under this regulation, the main obligations imposed on the operators of the specified aircraft models include ensuring that the required modifications to the exhaust muffler are completed within the stipulated timeframe. This involves adhering to the detailed specifications provided in either Aero Commander SB 1019 or FAA AD 73-1-1 (Section 105(4)). Operators must maintain accurate records of the modifications performed, ensuring that the changes align with the safety directives issued by the Civil Aviation Safety Authority (CASA) (Section 105(5)). Failure to comply with these requirements may result in non-compliance with airworthiness standards, potentially leading to operational restrictions or penalties. Breach of the provisions outlined in Section 105 of the Civil Aviation Regulations 1998 can result in significant consequences. Civil penalties may be imposed for non-compliance with the airworthiness directives, which can include fines and other financial penalties (Section 105(6)). Additionally, operational restrictions may be placed on the aircraft in question, potentially grounding the aeroplane until the required modifications are completed (Section 105(7)). In severe cases, CASA may pursue legal action against operators who persistently fail to comply with these directives, leading to further civil or criminal consequences (Section 105(8)). The exact penalties depend on the nature and severity of the breach, but they are designed to ensure that all aircraft meet the necessary safety standards to protect passengers and crew.
