AD/VAT/27 - Crankcase Breather Aerobatic Oil Trap - Removal

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, serve to regulate and ensure the safety of civil aviation within Australia. This comprehensive legislative instrument was introduced to address the need for stringent and standardised aviation safety measures to protect the public and maintain the integrity of the national airspace. One specific aspect of this regulation is found in Part 39 - 105, which includes the Airworthiness Directives for various aircraft types. These directives are essential in ensuring that aircraft meet the required safety standards, with a particular focus on identifying and mitigating potential hazards. The policy objective of these regulations is to maintain the highest possible safety standards in civil aviation, thus safeguarding both the passengers and the general public from aviation-related risks.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, encompasses a schedule of airworthiness directives that are applicable to certain aircraft models and their modifications. One such directive, AD/VAT/27, pertains to the Victa and A.E.S.L. Airtourer Series Aeroplanes, particularly those that are equipped with a Mod. No. B199 crankcase breather. This directive requires the removal of the aerobatic oil trap within 50 hours of the aircraft's time in service after 6 December 1966, as outlined in Victa Service Bulletin No. 63. The regulation applies to the specific aircraft models mentioned, ensuring that they meet the prescribed safety standards set by the Civil Aviation Safety Authority (CASA). This legislation is part of a broader framework that extends across the Commonwealth of Australia, enforcing compliance with aviation safety standards to protect public safety and maintain the integrity of civil aviation operations. The scope of this particular airworthiness directive is narrowly focused on Victa Airtourer 100 aeroplanes fitted with the specified engine modification. The directive does not explicitly mention exclusions or exemptions, implying that all aircraft fitting the described criteria must comply with the removal requirement. The application of this directive is directly tied to the operational use of these aircraft within Australia, as it falls under the regulatory purview of the Civil Aviation Regulations 1998. Furthermore, while the primary directive is clear in its requirements, additional specifications and enforcement details may be elaborated upon through subordinate instruments issued by CASA.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, include Airworthiness Directives (ADs) that establish mandatory requirements for certain types of aircraft to ensure their continued airworthiness. One such AD is AD/VAT/27, which pertains to the Victa and A.E.S.L. Airtourer Series Aeroplanes. This directive, issued on 11 June 1966, addresses the removal of the crankcase breather aerobatic oil trap on Victa Airtourer 100 aircraft fitted with Modification No. B199 (section 39-105(1)). The directive is applicable to any aircraft of this type that has accumulated 50 hours of time in service after 6 December 1966 (section 39-105(2)). Under the AD/VAT/27 directive, operators and owners of Victa Airtourer 100 aircraft with Mod. No. B199 must ensure compliance within the specified timeframe. This involves removing the crankcase breather aerobatic oil trap as outlined in Victa Service Bulletin No. 63 (section 39-105(3)). The directive is designed to enhance the aircraft's safety and operational efficiency by addressing a specific component that could potentially lead to oil contamination or system failure. Compliance with this directive is critical to maintaining the airworthiness of the aircraft and ensuring the safety of all occupants. Failure to comply with the AD/VAT/27 directive can result in serious consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce compliance and may take action against operators or owners who do not adhere to the specified requirements. Such actions may include fines, suspension or revocation of the aircraft’s certificate of airworthiness, or other regulatory measures to ensure the safety of the aviation industry (section 39-105(4)). In the event of a serious breach that results in an accident or incident, the penalties can be more severe, potentially involving criminal charges against individuals responsible for the non-compliance. The AD/VAT/27 directive underscores the importance of adhering to specific maintenance and operational standards to ensure the safety of aircraft and passengers. By mandating the removal of the crankcase breather aerobatic oil trap, the regulation aims to prevent potential hazards that could compromise flight safety. Compliance is not only a legal requirement but also a critical aspect of responsible aircraft operation, reflecting the high standards set by the Civil Aviation Regulations 1998.
