AD/VAT/5 - Control Column Torque Tube Bearing Spigots - Modification

Overview

The Civil Aviation Regulations 1998, under PART 39 - 105, address the need for ensuring the airworthiness of specific aircraft models. Enacted by the Commonwealth of Australia, these regulations were introduced to maintain safety standards in civil aviation, particularly focusing on the Victa and A.E.S.L. Airtourer Series Aeroplanes. The specific legislative instrument F2006B07579 (Legislative instrument) targets Victa Airtourer 100 and 115 models with serial numbers 1 to 16, requiring modifications to the control column torque tube bearing spigots. The policy objective is to ensure compliance before 1 September 1971, as referenced in Victa Service Bulletin No. 6, thereby enhancing overall aviation safety and addressing any potential mechanical issues within these aircraft models.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to the airworthiness directives for the Victa and A.E.S.L. Airtourer Series Aeroplanes, particularly addressing the control column torque tube bearing spigots. This legislation applies to Victa Airtourer 100 and 115 aircraft with serial numbers ranging from 1 to 16, mandating compliance with the requirements outlined in Victa Service Bulletin No. 6 prior to 1 September 1971. This regulation encompasses entities such as aircraft manufacturers, operators, and maintenance providers who must ensure the specified modifications are implemented to maintain airworthiness standards. The geographic reach of this regulation is nationwide, as it is administered by the Commonwealth of Australia under the Civil Aviation Safety Authority. There are no stated exclusions, exemptions, or thresholds within this directive, but the application and enforcement may extend through subordinate instruments to ensure compliance across the specified aircraft fleet.

Key Provisions

The Civil Aviation Regulations 1998 (Cth) provide detailed guidelines and requirements for ensuring the safety of civil aviation within Australia. Part 39 of these regulations, specifically section 105, concerns the Schedule of Airworthiness Directives. One such directive, AD/VAT/5, applies to Victa and A.E.S.L. Airtourer Series Aeroplanes. This particular directive focuses on the modification of the control column torque tube bearing spigots, which is essential for the safe operation of specific aircraft models. The directive applies to Victa Airtourer 100 and 115 models with serial numbers ranging from 1 to 16. To comply with this directive, owners and operators of the specified Victa Airtourer 100 and 115 models must ensure that the modifications outlined in Victa Service Bulletin No. 6 are implemented before 1 September 1971. This requirement ensures that the aircraft's control systems are maintained to the standards specified by the Civil Aviation Safety Authority (CASA). These modifications are necessary to address any potential safety issues related to the control column torque tube bearing spigots. Operators and owners of the affected aircraft must adhere to the specified compliance timeline and ensure that the modifications are correctly and thoroughly completed. Failure to comply with these requirements may result in the aircraft being deemed non-airworthy, potentially leading to grounding and other regulatory actions. CASA enforces these provisions rigorously to ensure that all aircraft meet the necessary safety standards before they are allowed to operate. In the event of non-compliance with the AD/VAT/5 directive, there may be significant consequences, including the imposition of penalties. While the specific penalties are not detailed in the excerpt provided, such breaches could lead to enforcement actions by CASA. These actions may include fines, orders for corrective action, or more severe measures such as suspension or revocation of the aircraft's operating certificate. Ensuring adherence to the specified directives is therefore crucial for all operators and owners to maintain their aircraft's airworthiness and avoid potential legal and financial repercussions.
