AD/VAT/4 - Outboard Elevator and Tailplane Hinge - Inspection

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA) under the legislative framework of the Civil Aviation Act 1988, was enacted to ensure the safety and efficiency of civil aviation in Australia. The regulations address the need to maintain airworthiness standards, particularly in light of the diverse range of aircraft types and operations within the country. The specific legislative instrument F2006B07574 pertains to the Victa and A.E.S.L. Airtourer Series Aeroplanes, aiming to mitigate risks associated with the outboard elevator and tailplane hinge fittings. This instrument requires inspections of certain parts to ensure structural integrity and prevent potential failures that could compromise flight safety. The overarching policy objective is to uphold the highest safety standards in civil aviation by mandating regular inspections and maintenance checks on critical aircraft components.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 within the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to the Victa Airtourer 100 and 115 aeroplanes with serial numbers ranging from 1 to 14 that do not incorporate Modification B27. This regulation mandates the inspection of the outboard elevator and tailplane hinge fittings, specifically parts numbered 0221012 and 0220009, for any cracks, with a particular focus on the bend radius of the elevator hinge part number 0221012. This inspection must be conducted at intervals not exceeding 25 hours of time in service, effective from 1 September 1971. The geographic and jurisdictional reach of these regulations is national, administered under the Commonwealth of Australia's oversight by the Civil Aviation Safety Authority. The regulations do not specify exclusions, exemptions, or thresholds beyond the outlined applicability and compliance requirements. The application of these regulations may be further extended or restricted through subordinate instruments as deemed necessary by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105 concerning the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, address the maintenance requirements for the Victa and A.E.S.L. Airtourer Series Aeroplanes, particularly those with serial numbers 1 to 14, excluding those incorporating Modification B27. According to AD/VAT/4, a critical inspection requirement is outlined for the outboard elevator and tailplane hinge fittings. Operators must inspect the elevator hinge fittings P/N 0221012 and the tailplane hinge fitting P/N 0220009 for any signs of cracks, with a specific focus on the bend radius area of the elevator hinge P/N 0221012. These inspections are mandated to occur at intervals not exceeding 25 hours of time in service, beginning from 1 September 1971. The requirement is aimed at ensuring the continued airworthiness and safety of the aircraft by preventing structural failures that could arise from undetected cracks in these critical components. Compliance with these directives is essential for maintaining the safety standards set by CASA and is a non-negotiable part of the operational protocol for these specific models. Operators of these aircraft must adhere to these inspection intervals strictly. Failure to conduct these inspections within the prescribed timeframes could lead to non-compliance with the regulations, potentially resulting in the aircraft being grounded until the required inspections are performed. The obligation to perform these inspections falls directly on the aircraft operator, who must ensure that the inspections are carried out by qualified personnel, and that any identified issues are addressed immediately to maintain the aircraft's airworthiness. Breaches of these requirements can result in significant consequences, including potential enforcement actions by CASA. The penalties for non-compliance can be severe, encompassing both civil and criminal liabilities. Civil penalties may include fines and orders for corrective actions, while criminal penalties could involve imprisonment, depending on the severity of the breach and the risk posed to public safety. The exact penalties are not detailed in the provided text, but they can be substantial, reflecting the importance of adhering to these safety directives.
