Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, serve as the foundational legal framework for the regulation of civil aviation within Australia. Among these regulations, Part 39 addresses airworthiness directives, which are critical for ensuring the safety and compliance of aircraft. The specific legislative instrument F2006B08209 pertains to the Cessna 320 Series Aeroplanes, aiming to address the identified need for regular inspections of the nose gear main drive tube assembly. This legislative measure was introduced to mitigate potential risks associated with wear and tear in the nose gear components, thereby enhancing overall flight safety. The policy objective is to mandate timely and thorough inspections of the specified parts, ensuring that any issues are identified and rectified before they can compromise the integrity of the aircraft. Compliance with these directives is required within a defined timeframe to ensure the continuous safety of air travel.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, applies to all Cessna 320 series aeroplanes that have exceeded 1000 hours of time in service. This regulation sets out requirements for inspecting the nose gear main drive tube assembly, particularly focusing on the bearing and its connection to the nose gear main drive tube. Compliance with these directives is mandatory for all entities operating such aircraft within Australia, as the regulation operates under national jurisdiction. The requirement necessitates that inspections be conducted within 100 hours of time in service from 5 September 1968 and subsequently at intervals not exceeding 200 hours of time in service. Any deviations from these requirements could result in the aircraft being deemed non-airworthy. This directive does not specify any exclusions or exemptions, thereby applying uniformly across all relevant operators and aircraft within the specified conditions.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, contain provisions that govern the airworthiness directives for the Cessna 320 series aeroplanes. In this instance, AD/CESSNA 320/3 pertains to the nose gear main drive tube assembly and outlines the inspection requirements for this critical component. According to the directive (Section 9/68), the requirement applies to all Cessna 320 series aeroplanes that have exceeded 1000 hours of time in service. The directive mandates two primary inspection tasks: first, inspecting the bearing P/N 4NBC612ZP for any movement between the outer race and the eye end of the nose gear main drive tube P/N 0842120-1 (Section 9/68(1)); and second, if any movement is detected, the entire nose gear assembly must be inspected for damage or incorrect adjustment, with a particular focus on the inflation of the shock leg (Section 9/68(2)). The obligations under the Civil Aviation Regulations 1998 for the entities governed by this directive include adhering to the specified inspection schedule. Operators of the Cessna 320 series aeroplanes must ensure that the required inspections are conducted within 100 hours of time in service from the date of the directive (5 September 1968) and subsequently at intervals not exceeding 200 hours of time in service. This compliance is crucial for maintaining the airworthiness of the aircraft and ensuring safety standards are met. Failure to conduct these inspections in accordance with the directive can lead to serious safety issues and potential regulatory action. For breach of these obligations, the Civil Aviation Regulations 1998 do not explicitly state the specific penalties or consequences within the provided text. However, non-compliance with airworthiness directives generally can result in severe civil or criminal penalties under Australian aviation law. These can include fines, operational restrictions, and in serious cases, prosecution. The specific penalties are determined by the severity of the breach and the potential risk to public safety, which can vary widely depending on the circumstances. It is important for operators to meticulously follow the directive to avoid any legal repercussions and ensure the safety and reliability of their aircraft.
