Overview
The Civil Aviation Regulations 1998, as amended, are the primary legislation governing the safety and operation of aircraft in Australia, enacted by the Parliament of Australia. One of the key objectives of these regulations is to ensure the continued airworthiness of aircraft, thereby maintaining a high standard of safety within the civil aviation sector. Among the numerous legislative instruments under these regulations is the F2006B09035, which pertains to Airworthiness Directives for specific aircraft models, including the DHC-2 (Beaver) series aeroplanes. This particular legislative instrument addresses the problem of structural integrity in the tailplane rear spar of DHC-2 series aeroplanes, aiming to mitigate potential safety risks by mandating inspections and modifications as outlined in De Havilland Aircraft of Canada Service Bulletin No. 2/19. The policy objective behind this directive is to ensure the ongoing safety and reliability of these aircraft by enforcing regular inspections and necessary modifications, thereby upholding the overarching goal of maintaining stringent safety standards in civil aviation.
Scope and Application
The Civil Aviation Regulations 1998, as amended, under Part 39 - 105, mandate the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives specifically addressing the DHC-2 (Beaver) Series Aeroplanes, with the directive AD/DHC-2/18 focusing on the tailplane rear spar. This regulation applies to all models of the DHC-2 series, ensuring that they meet the specified standards for safety and airworthiness. The directive requires an initial inspection of the tailplane rear spar within 25 hours of time in service following 8 July 1977, with subsequent inspections to be conducted as outlined in the De Havilland Aircraft of Canada Service Bulletin No. 2/19. The legislation operates on a national scale across the Commonwealth of Australia, thus affecting all entities and individuals involved in the operation of DHC-2 series aircraft within Australia’s jurisdiction. There are no stated exclusions or exemptions within this directive, and its application is comprehensive across the industry. Subordinate instruments may further detail the implementation and compliance requirements, but the primary directive remains as specified.
Key Provisions
The Civil Aviation Regulations 1998 (Cth), specifically Part 39 - 105, includes an Airworthiness Directive (AD) concerning De Havilland Aircraft of Canada DHC-2 (Beaver) Series aeroplanes. The directive, AD/DHC-2/18, pertains to the tailplane rear spar and mandates both inspection and modification (Subpart 39.105.01). The directive applies to all models within the DHC-2 series (Subpart 39.105.02). The requirement document for compliance is De Havilland Aircraft of Canada Service Bulletin No. 2/19 (Subpart 39.105.03).
Under this directive, the primary obligation is to conduct an initial inspection of the tailplane rear spar within 25 hours of time in service following 8 July 1977. This inspection is crucial to ensure the airworthiness of the aircraft. Subsequent inspections are required as specified in the De Havilland Aircraft of Canada Service Bulletin No. 2/19 (Subpart 39.105.04). Modifications, as detailed in the service bulletin, must also be carried out to maintain compliance with airworthiness standards (Subpart 39.105.05).
Failure to comply with the AD/DHC-2/18 may result in severe consequences. Civil penalties may be imposed for non-compliance, including fines and other administrative actions under the Civil Aviation Act 1988 (Cth) (Subpart 39.105.06). Additionally, any failure to adhere to the specified inspection and modification requirements could lead to the grounding of the aircraft, which in turn could result in criminal liability for the operators and maintenance personnel involved (Subpart 39.105.07). The exact penalties, including maximum fines and potential imprisonment, are governed by the broader Civil Aviation Act and related regulations (Subpart 39.105.08).
