Overview

The Civil Aviation Safety Regulations 1998, enacted by the Parliament of Australia, establish and enforce safety standards for aircraft and aeronautical products to ensure the safety of civil aviation. This legislation was introduced to address the need for a robust regulatory framework that maintains airworthiness and safety standards in line with international best practices. The Regulations are administered by the Civil Aviation Safety Authority (CASA), which is tasked with ensuring that all aspects of civil aviation in Australia comply with safety and operational standards. This particular Airworthiness Directive (AD) was issued to address a specific safety concern identified with the Avions Mudry Cap Series Aeroplanes, specifically the front tank support strap of Model CAP 10B aircraft. The policy objective is to mandate corrective action to eliminate unsafe conditions, thereby preventing potential hazards and ensuring the continued safety of aviation operations.

Scope and Application

The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, provides a framework through which the Civil Aviation Safety Authority (CASA) can issue Airworthiness Directives (ADs) to address safety concerns related to aircraft or aeronautical products. This particular AD, issued under subregulation 39.1 (1) of the Civil Aviation Safety Regulations 1998, applies to all Model CAP 10B aircraft, mandating that the front tank support strap be retired from service in accordance with specified instructions. The directive, which came into effect on 8 July 2004, was prompted by a failure of a front tank support strap on a CAP 10B aircraft, leading to the imposition of a life limit of 4,000 flight hours for such components. The AD is applicable across the Commonwealth of Australia, as it is issued by a delegate of CASA, which has jurisdictional authority over civil aviation safety nationwide. The directive does not explicitly mention any exclusions or exemptions but is enforced in compliance with the specific requirements outlined in the accompanying service bulletin and the AD itself.

Key Provisions

The main operative sections of the Airworthiness Directive (AD/CAP 10/5) require that all Model CAP 10B aircraft must retire the front tank support strap from service, as detailed in Apex Aircraft Service Bulletin No. 040102 dated 10 May 2004. This directive, issued under subregulation 39.1 (1) of the Civil Aviation Safety Regulations 1998, is necessitated by a reported failure of a front tank support strap on a CAP 10B aircraft. The directive mandates the retirement of the front tank support strap in accordance with the specified service bulletin, with a life limit of 4,000 flight hours imposed following the reported incident. The obligations imposed by this Act on the relevant parties primarily concern compliance with the directive. Aircraft operators and owners must ensure that the front tank support strap is retired from service in accordance with the instructions provided in the referenced service bulletin. This includes adherence to the revised effective date of 8 July 2004, as specified in the directive. The directive also necessitates that any required maintenance or replacement of the front tank support strap is conducted by authorised personnel and facilities in compliance with the relevant regulations. Failure to comply with the Airworthiness Directive can result in significant consequences. Under the Civil Aviation Safety Regulations, non-compliance can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The potential penalties include fines and other civil or criminal sanctions, depending on the severity and impact of the non-compliance. While the specific maximum penalties are not detailed in the directive itself, the overarching regulations provide for substantial fines and potential criminal charges for serious breaches that compromise aviation safety.
