Overview
The Civil Aviation Regulations 1998, as amended by the Legislative Instrument F2006B02569, address specific safety concerns relating to the airworthiness of Auster/Beagle A.61 Series Aeroplanes. This legislation was introduced to ensure that certain models of these aircraft meet stringent safety standards, particularly concerning the fabric covering on their wings. Enacted by the Commonwealth of Australia, this regulation aims to enhance the safety of civil aviation by mandating specific modifications to the wing rib stringing and fabric covering, as outlined in Airworthiness Directive AD/AUS/18. The policy objective is to ensure that these aircraft are maintained in a safe and reliable condition, thereby protecting both the occupants and the general public from potential hazards associated with non-compliance. Compliance with these directives is mandatory and must be achieved forthwith, as stipulated in the regulations.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the application of Airworthiness Directives issued by the Civil Aviation Safety Authority (CASA). The scope of this particular directive, AD/AUS/18, pertains to the fabric covering of Auster/Beagle A.61 Series Aeroplanes, targeting certain models including Mk. III, Mk. IV, Mk. V, J1, J1B, J1N, J2, J4, and J5 series with wings not covered according to specified drawings. The directive applies to aircraft owners, operators, and maintenance personnel who must comply with the prescribed modifications to ensure the airworthiness of these aeroplanes. Geographically, the directive applies nationally within Australia, reflecting CASA's regulatory authority across the Commonwealth. Compliance with this directive is mandatory, requiring immediate action upon notification, and it extends to the use of approved recovery schemes and relevant service bulletins for accurate implementation. Subordinate instruments may further detail compliance requirements and enforcement mechanisms.
Key Provisions
The Civil Aviation Regulations 1998, specifically under Part 39 - 105, detail the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for Auster/Beagle A.61 Series Aeroplanes, identified by AD/AUS/18 (section 1). This directive applies to specific models of Auster/Beagle aeroplanes, including the Mk. III, Mk. IV, V, J1, J1B, J1N, J2, J4, J5, and other J5 series, provided their wings are not covered according to specific drawings (section 2). The primary requirements of this directive involve modifying the wing rib stringing to introduce additional stringing in the leading edge area, as referenced in Beagle Drawing No. CSK 3483 (section 3). Additionally, when it becomes necessary to recover the wing, it must adhere to the appropriate recovery scheme specified in paragraph 1, or an alternative scheme approved by the Secretary (section 4). Detailed information can be found in Beagle Service Bulletin (Auster Series) No. 53 (section 5).
Entities and individuals governed by this directive must ensure that their aeroplanes comply with the specified modifications and recovery schemes. This involves not only the physical modification of the aeroplane's wing structure but also ensuring that any recovery of the wing is done according to the prescribed or approved schemes (section 6). Compliance with these requirements is mandatory and must be achieved forthwith (section 7).
Failure to comply with the provisions of AD/AUS/18 may result in various legal and safety consequences. Although specific penalties are not detailed within this directive, non-compliance with CASA regulations can result in enforcement actions under the Civil Aviation Act 1988, which may include fines, imprisonment, or both. Additionally, non-compliance can lead to the grounding of the aeroplane, potentially resulting in significant operational disruptions and safety risks (section 8). The seriousness of these consequences underscores the importance of adhering to the specified requirements and timelines.
