AD/AIRCON/3 - Godfrey Cabin Supercharger Type 15 - Rotor Balance - Inspection

Overview

The Civil Aviation Regulations 1998, which were enacted by the Parliament of Australia, constitute a comprehensive framework governing various aspects of civil aviation in Australia. One of the key components of these regulations is Part 39, which pertains to the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. This particular legislative instrument, F2006B02229, addresses the critical issue of ensuring the safety and airworthiness of aircraft through specific directives, such as AD/AIRCON/3 concerning the Godfrey Cabin Supercharger Type 15 rotor. This directive was introduced to mitigate risks associated with the dynamic balance of rotors, aiming to prevent mechanical failures that could compromise flight safety. The policy objective is to ensure that all rotors meet the specified balance requirements, thereby enhancing the overall safety of air travel.

Scope and Application

The Civil Aviation Regulations 1998, as amended, under the legislative instrument F2006B02229, pertain to the maintenance and inspection of airworthiness directives specifically targeting aircraft cabin supercharger rotors. This regulation applies to all Godfrey Cabin Superchargers Type 15 used in aviation, ensuring that both new and used rotors meet stringent safety standards. New rotors must be dynamically balanced to within 0.020oz. as specified in the approved overhaul manual before their initial installation in an aircraft. For used rotors, this balancing requirement must be fulfilled before reinstallation following each overhaul conducted after 30 January 1968. The regulation's scope is confined to the operational and maintenance requirements of the specified superchargers within the aviation industry, with no broader geographic or jurisdictional reach beyond what is defined in the Civil Aviation Regulations 1998. The regulation does not explicitly mention exclusions or exemptions, and its application extends to any person or entity involved in the maintenance or operation of aircraft fitted with the specified superchargers.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 107, outlines the Civil Aviation Safety Authority's schedule of airworthiness directives, which includes detailed technical requirements for maintaining aircraft components. Under this legislation, AD/AIRCON/3 focuses on the Godfrey Cabin Supercharger Type 15 rotor (section 1). This directive mandates that the rotors must be dynamically balanced to within 0.020 ounces as specified in the approved overhaul manual (section 2). This applies to both new and used rotors, with new rotors requiring balance before their initial installation in an aircraft, and used rotors needing re-balancing before installation following any overhaul completed after 30 January 1968 (section 3). Compliance with these airworthiness directives is crucial for ensuring the safety and airworthiness of aircraft. The regulations impose an obligation on the owners and operators of aircraft to adhere to these specific requirements. They must ensure that the rotors are balanced according to the specified tolerances and procedures to prevent potential safety issues that could arise from imbalanced rotors (section 4). The requirement extends to both new and used rotors, highlighting the importance of maintaining these components' integrity throughout their lifecycle in aircraft operations (section 5). Failure to comply with these airworthiness directives can result in serious safety risks and potential legal consequences. The Civil Aviation Regulations 1998 do not explicitly detail specific penalties within this directive, but non-compliance with airworthiness directives generally can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Such actions may include fines, suspension or revocation of aircraft operating certificates, or other regulatory measures to ensure compliance and maintain safety standards (section 6). The potential penalties underscore the importance of adhering to these technical requirements to avoid adverse outcomes for aircraft operators and owners.
