This revises recurring inspection intervals.
Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes a schedule of airworthiness directives that aim to maintain the safety standards of civil aviation in Australia. One such directive is AD/EMB-110/25, which was enacted to address safety issues identified with the Embraer EMB-110 (Bandeirante) Series Aeroplanes. This directive applies to all model EMB-110 aircraft with serial numbers ranging from 110001 to 110472. The primary problem it seeks to resolve is the fracture of certain torque link keys, specifically P/N 14468 or P/N 14468A, which has been observed to occur after a certain number of landings. The policy objective behind this directive is to ensure that these parts are replaced or inspected at specified intervals to prevent potential failures that could compromise the safety of the aircraft. Compliance with these directives is mandatory, overseen by the Civil Aviation Safety Authority, to ensure that the risks associated with these components are effectively managed.
Scope and Application
The Embraer EMB-110 (Bandeirante) Series Aeroplanes Airworthiness Directive, specified under the Civil Aviation Regulations 1998, applies to all model EMB-110 aircraft with serial numbers ranging from 110001 through 110472. This directive is enforced by the Civil Aviation Safety Authority and pertains to the main landing gear torque link key. The directive mandates compliance with Embraer Service Bulletin SB 110-032-0056 Rev. 3, which outlines the actions required for the replacement of keys P/N 14468 or P/N 14468A. Compliance must occur within 50 hours of time in service after 13 July 1989 for keys that have achieved 2950 landings, or before reaching 3000 landings, whichever comes first. Subsequent inspections must be conducted at intervals specified in the Requirement Document. This directive is a direct response to the identified risk of fracture in the specified torque link keys, necessitating their replacement to ensure continued airworthiness.
Key Provisions
The Civil Aviation Regulations 1998, under Part 39, specifically in section 39-105, mandate the application of airworthiness directives for certain aircraft models. In this case, the Embraer EMB-110 (Bandeirante) Series Aeroplanes are covered by Airworthiness Directive AD/EMB-110/25 Amendment 3. This directive is applicable to all model EMB-110 aircraft with serial numbers ranging from 110001 through 110472. The primary requirement outlined in this directive is the action to be taken in accordance with Embraer Service Bulletin (SB) 110-032-0056, Revision 3, concerning the Main Landing Gear Torque Link Key. The directive stipulates that any keys with part numbers P/N 14468 or P/N 14468A that have achieved 2950 landings must be replaced within 50 hours of time in service after 13 July 1989, or before the aircraft achieves 3000 landings, whichever occurs first. Subsequent to this initial compliance, inspections must be carried out at intervals specified in the Requirement Document.
Entities and parties governed by these regulations are required to adhere to strict timelines and procedures for replacing and inspecting the torque link keys. Specifically, they must ensure that the replacements are carried out in a timely manner to avoid reaching the 3000-landing threshold without updated keys. This involves meticulous record-keeping and scheduling of inspections as per the intervals defined in the Requirement Document. The directive also references Brazilian Airworthiness Directive AD 82-12-02, Revision 3, which correlates to the original requirement document, indicating an international alignment in safety standards.
Failure to comply with the requirements set forth in the Civil Aviation Regulations 1998 can lead to significant legal and operational consequences. Non-compliance with airworthiness directives can result in penalties, which may include both civil and criminal liabilities. The exact penalties are determined by the Civil Aviation Safety Authority (CASA) and can vary based on the severity and frequency of the breach. While the specific maximum penalties are not detailed in the provided text, it is clear that strict adherence to these directives is essential to avoid any potential legal repercussions or safety risks.
