AD/HS 125/38 - Elevator Trim Tabs - Inspection and Modification

Overview

The Civil Aviation Regulations 1998 (Cth), enacted by the Commonwealth Parliament, form a comprehensive regulatory framework governing aviation safety and operations in Australia. One specific legislative instrument under this regulatory scheme is F2006B10477, which pertains to the British Aerospace BAe 125 Series Aeroplanes. This particular instrument addresses the inspection and modification of elevator trim tabs within the specified aircraft series, as detailed in AD/HS 125/38 11/74. This directive was introduced to ensure the airworthiness of the aircraft, aligning with the overarching policy objective of maintaining high safety standards in the civil aviation sector. Notably, the listed content has been removed from the schedule as the specified aircraft model is not currently registered, reflecting the dynamic nature of the regulatory framework that adapts to the current fleet composition and emerging safety concerns.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives for British Aerospace BAe 125 Series Aeroplanes. This legislation applies to all entities and persons involved in the operation, maintenance, and modification of the BAe 125 Series aeroplanes within Australia, encompassing both commercial and private aviation sectors. The regulations set forth stringent requirements for the inspection and modification of elevator trim tabs to ensure compliance with safety standards, although it is noted that the specific directive AD/HS 125/38 has been removed as the aircraft model is not currently registered. The scope of the legislation is national, operating under the Commonwealth of Australia, with CASA exercising its authority to enforce these directives. The exclusion of the particular AD/HS 125/38 from the listing signifies that any obligations under this directive do not apply to the BAe 125 Series aeroplanes that are not registered. However, the broader regulations remain in effect, mandating that all other applicable safety directives be adhered to. The Civil Aviation Regulations 1998 can extend or restrict their application through subordinate instruments, ensuring that the evolving nature of aviation safety standards is appropriately managed and enforced.

Key Provisions

The Civil Aviation Safety Authority (CASA) has issued the Airworthiness Directive (AD) under Part 39 of the Civil Aviation Regulations 1998. Specifically, AD/HS 125/38 pertains to the British Aerospace BAe 125 series aeroplanes, focusing on elevator trim tabs. While the specific contents of this AD have been removed as the aircraft model is no longer registered, historically, this directive would have required operators of BAe 125 series aeroplanes to inspect and, if necessary, modify the elevator trim tabs. Such inspections and modifications are aimed at ensuring the aircraft's continued airworthiness and safety. Under this directive, operators of BAe 125 series aeroplanes must comply with the specified requirements concerning the elevator trim tabs. This includes conducting thorough inspections to check for any signs of wear, damage, or other issues that could affect the aircraft's performance. If any problems are identified during the inspection, operators must follow the prescribed procedures to modify or repair the trim tabs as necessary. The aim of these obligations is to prevent potential hazards that could compromise the safety of the flight. Failure to comply with the AD could result in serious consequences. If an operator fails to adhere to the requirements for inspecting and modifying the elevator trim tabs, they could be in breach of the Civil Aviation Regulations 1998. Such a breach could lead to enforcement actions by CASA, including fines, penalties, or other regulatory measures. The specific penalties for non-compliance would depend on the severity of the breach and could include substantial financial penalties. Additionally, persistent non-compliance could result in the grounding of the aircraft until the necessary modifications are made, potentially disrupting flight schedules and operations.
