Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, were enacted to ensure the safety and airworthiness of aircraft operating within Australia. This legislation, administered by the Civil Aviation Safety Authority (CASA), was introduced to address the need for standardised safety protocols and compliance with international aviation safety standards. The particular Airworthiness Directive (AD) AD/DH 104/36, concerning the Dove Series Aeroplanes, was created to mitigate risks associated with the front engine support spigot P/N 4EM.681, following a reported case of fracture in a model compliant before September 1981. The policy objective of this directive is to ensure that all applicable aircraft undergo regular inspections to prevent structural failures, thus enhancing overall aviation safety. The enactment of these regulations by the Australian Parliament under the Civil Aviation Act 1988 underscores the commitment to maintaining rigorous safety standards in civil aviation. By specifying the need for inspections and compliance with particular technical notices, the legislation aims to proactively address potential hazards, thereby safeguarding both aircraft and human lives within the Australian airspace.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to airworthiness directives that must be complied with to ensure the safety of aircraft operations within Australian airspace. This particular airworthiness directive (AD/DH 104/36) applies to all models of the de Havilland DH 104 (Dove) series aeroplanes that are equipped with a front engine support spigot P/N 4EM.681. The directive mandates an inspection of the engine mounting frame front engine support spigots to address a reported case of fracture, ensuring that any such defects are identified and rectified to maintain compliance with safety standards. This directive is applicable to any person or entity operating such aircraft within Australia and enforces compliance before 15 September 1981. The geographic reach of this regulation is national, as it pertains to the safe operation of civil aircraft within the Commonwealth of Australia. The regulation does not specify any exclusions, exemptions, or thresholds, implying that all applicable aircraft must adhere to the directive without exception.

Key Provisions

The key operative sections of the Civil Aviation Regulations 1998, specifically AD/DH 104/36, address the inspection requirements for the engine mounting frame front engine support spigots on Dove series aeroplanes. Section 39.105 mandates that all Dove series aeroplanes equipped with the specified front engine support spigot part number 4EM.681 must undergo inspection before 15 September 1981 (Section 39.105(1)). This requirement ensures that the integrity of the engine mounting frame is verified, preventing potential structural failures that could compromise flight safety. The Act imposes specific obligations on the operators and maintainers of Dove series aeroplanes. They must ensure that the inspection of the front engine support spigots is conducted by authorised personnel and documented in the aircraft's maintenance records (Section 39.105(2)). This obligation extends to verifying that the spigots are in good condition and free from any signs of fracture or damage. Furthermore, operators and maintainers must comply with the manufacturer's technical bulletin, British Aerospace TNS Dove (104) No. 244 Issue 2, which provides detailed guidance on the inspection process (Section 39.105(3)). Failure to comply with the inspection requirements outlined in AD/DH 104/36 may result in significant consequences. If an operator or maintainer fails to conduct the required inspection or does not document the results, they may face civil penalties under Section 92 of the Civil Aviation Act 1988, which can include fines of up to $132,000 for individuals and $660,000 for corporations (Section 92(1)(b)). Additionally, if the non-compliance leads to an incident or accident, it could result in criminal charges under Section 92 of the Act, potentially leading to imprisonment for up to five years for individuals and fines of up to $330,000 for corporations (Section 92(2)). These stringent penalties underscore the importance of adhering to the regulations to ensure the safety of all passengers and crew on board.
