AD/CESSNA 320/17 - Wing Leading Edge Fuel Lines and Wiring - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority, include a schedule of airworthiness directives designed to ensure the safety of aircraft operations within Australian airspace. One such directive is AD/CESSNA 320/17, which was introduced to address specific issues related to the wing leading edge fuel lines and wiring in Cessna 320 series aeroplanes. This directive applies to all models 320 with serial numbers ranging from 320-0001 to 320F0045 and mandates compliance within 100 hours of time in service following the directive's issuance on 29 June 1973. The objective of this directive is to mitigate potential safety risks associated with these components by requiring inspection and necessary modifications as outlined in the referenced document Cessna SL ME73-5. This legislative instrument aims to enhance the safety and reliability of the specified aircraft models by addressing vulnerabilities in the wing leading edge fuel lines and wiring. By mandating a thorough inspection and modification process, the regulation ensures that these critical components meet the necessary safety standards, thereby contributing to the overall safety of civil aviation within Australia. The directive reflects the Civil Aviation Safety Authority's commitment to maintaining stringent safety protocols and mitigating potential hazards associated with aircraft operations.

Scope and Application

The Civil Aviation Regulations 1998, as detailed in the Schedule of Airworthiness Directives, specifically addresses the Cessna 320 series aeroplanes, applying to all models 320 with serial numbers ranging from 320-0001 to 320F0045. This legislative instrument is applicable to the operators and owners of these aircraft, mandating that compliance with the directive concerning wing leading edge fuel lines and wiring must be achieved within 100 hours of time in service following the directive's issuance date of 29 June 1973. The directive pertains to inspections and necessary modifications to ensure continued airworthiness and safety of the aircraft, thus directly affecting the aviation industry and the conduct of those involved in the operation of the specified Cessna models. The directive is under the jurisdiction of the Commonwealth of Australia, with the Civil Aviation Safety Authority responsible for enforcing compliance and overseeing the safety measures detailed within the directive. The applicability of AD/CESSNA 320/17 extends solely to the specified Cessna 320 series aeroplanes within the Commonwealth of Australia, and there are no stated exclusions or exemptions within the directive itself. However, further guidance and detailed implementation may be provided through subordinate instruments or additional regulatory documents, which could elaborate on procedures and specific compliance requirements. This legislative instrument ensures that the specified aircraft meet stringent safety standards, thereby safeguarding the integrity and safety of civil aviation within Australia.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, particularly the Cessna 320 Series Aeroplanes AD/CESSNA 320/17, focus on the inspection and modification of wing leading edge fuel lines and wiring. Section 39-105 specifies that all models 320 with serial numbers ranging from 320-0001 to 320F0045 must undergo these inspections and modifications. Compliance with these directives is required within 100 hours of time in service after 29 June 1973. The Act imposes several obligations on the parties involved. Firstly, operators of the specified Cessna 320 models must ensure that the inspections and modifications outlined in the directive are completed within the stipulated timeframe. This includes verifying that the wing leading edge fuel lines and wiring are in compliance with the detailed specifications provided in the Cessna SL ME73-5 document. Operators must also keep thorough records of all inspections and modifications performed, as well as any repairs made to the affected areas. Failure to comply with these provisions can lead to significant consequences. Under the Civil Aviation Regulations, non-compliance with an Airworthiness Directive can result in civil penalties. For individuals, the maximum penalty can be a fine of up to $21,000, while for corporations, the fine can be as high as $105,000. Additionally, persistent non-compliance can lead to more severe consequences, including the potential grounding of the aircraft until the required modifications are made. This can have significant operational and financial impacts on the operators. In cases where the non-compliance results in an aviation incident or accident, the penalties can escalate to criminal charges. The severity of these charges depends on the nature of the non-compliance and the resultant consequences. Operators found to have deliberately ignored the directives could face imprisonment, further highlighting the importance of strict adherence to these safety requirements. Therefore, it is imperative for operators to take these obligations seriously to avoid any legal repercussions and ensure the safety of their operations.
