Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes amendments concerning the airworthiness directives for Pilatus Britten-Norman BN-2 series aeroplanes, addressing issues such as elevator trim tab cracking. This legislative instrument, known as F2006B04753, was introduced to ensure that all relevant models comply with specific safety standards. The Act was enacted by the Commonwealth of Australia, with the aim of maintaining and improving aviation safety standards. The directive aims to prevent and address structural issues in the specified aircraft models by mandating specific modifications and inspections, thereby reducing the risk of in-flight failures.
The policy objective behind this legislation is to ensure that all aircraft meet stringent airworthiness criteria, thus protecting the safety of passengers and crew. The Civil Aviation Safety Authority, through this directive, extends the post-modification inspection interval for certain components, such as the elevator trim tab, to every 100 hours of total flight time. This approach reflects a commitment to proactive safety measures, ensuring that any identified issues are rectified before they can pose a risk to flight operations.
Scope and Application
The Civil Aviation Regulations 1998, as amended and detailed in Schedule 105, governs the airworthiness directives for specific aircraft types, including the Pilatus Britten-Norman BN-2 Series Aeroplanes. This legislation mandates compliance with Airworthiness Directive AD/BN-2/42 Amendment 3, which specifically addresses elevator trim tab cracking. All models listed in the Requirement Document are subject to this directive, ensuring they meet the necessary safety standards before being issued a Certificate of Airworthiness. Compliance involves modifying the aircraft as per Pilatus Britten-Norman BN-2/S.B 142 Issue 4 and conducting inspections according to the specified Requirement Document, with a post-modification inspection interval extended to every 100 hours T.I.S. The application of this directive is national, encompassing all relevant aircraft within the Commonwealth of Australia. There are no stated exclusions, exemptions, or thresholds within the scope of this directive, though compliance specifics may be further detailed in subordinate instruments.
Key Provisions
The main operative sections of this legislative instrument pertain to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives (ADs) for the Pilatus Britten-Norman BN-2 Series Aeroplanes. Specifically, AD/BN-2/42 Amendment 3 addresses elevator trim tab cracking (section 4/86). This directive applies to all models listed in the Requirement Document and mandates actions in accordance with the Pilatus Britten-Norman BN-2/S.B 142 Issue 4. The primary requirement is that modifications must be made before issuing a Certificate of Airworthiness, and subsequent inspections must be carried out as specified in the Requirement Document. Additionally, Issue 4 of the Requirement Document extends the post-modification inspection interval to every 100 hours of total in-service time (T.I.S).
The obligations imposed by this Act on the parties and entities it governs are centred around ensuring compliance with the AD/BN-2/42 Amendment 3. Operators and owners of the affected Pilatus Britten-Norman BN-2 Series Aeroplanes must adhere to the modification requirements outlined in the Pilatus Britten-Norman BN-2/S.B 142 Issue 4. This includes making the necessary modifications to the elevator trim tabs before the aircraft can be deemed airworthy. Furthermore, they must conduct inspections in accordance with the Requirement Document, with the extended interval of every 100 hours of T.I.S as specified. Failure to comply with these directives can result in severe consequences, including potential grounding of the aircraft.
The consequences of breaching these directives can be significant. The Act outlines specific offences and penalties for non-compliance with the ADs. In this instance, failure to adhere to the elevator trim tab modification and inspection requirements can result in substantial civil or criminal penalties. While the exact penalties are not detailed in this particular legislative instrument, general regulations under the Civil Aviation Act 1988 provide a framework for enforcement. Penalties for non-compliance can include fines, imprisonment, or both, depending on the severity of the breach and the discretion of the court. The maximum penalties under the Civil Aviation Act 1988 can reach up to AUD 210,000 for corporations and AUD 21,000 for individuals, along with potential imprisonment terms.
In summary, the AD/BN-2/42 Amendment 3 mandates specific actions and inspections related to elevator trim tab cracking for the Pilatus Britten-Norman BN-2 Series Aeroplanes. Operators and owners must ensure modifications are made and inspections are conducted as per the Requirement Document, with an extended post-modification inspection interval of every 100 hours of T.I.S. Non-compliance with these directives can lead to serious civil and criminal penalties, reflecting the importance of adhering to aviation safety regulations.
