Compliance: Unless already accomplished, within 100 hours time in service after 3 December 1998.
This Airworthiness Directive becomes effective on 3 December 1998.
COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Background: It has been determined that the collective idler link and the collective lever, when manufactured from two different materials, have substantially different airworthiness lives, while still being identified with a single part number. Parts manufactured from forged material have a longer life than those of rolled plate stock. Therefore, re- identification of the affected parts and corresponding life limitation are necessary.
Overview
The Civil Aviation Regulations 1998, introduced by the Commonwealth of Australia, aim to ensure the safety and airworthiness of aircraft within Australia. This legislation, enacted by the Australian Parliament, is designed to address gaps and problems in the oversight and regulation of civil aviation. Specifically, Part 39 - 105 of the Civil Aviation Regulations 1998 includes airworthiness directives, which are legally enforceable rules or instructions issued by the Civil Aviation Safety Authority to address safety issues with aircraft, components, or parts. The policy objective is to maintain the highest standards of safety in the operation of aircraft by ensuring that all parts meet specific airworthiness criteria. The Airworthiness Directive AD/BELL 206/140 concerning the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters is an example of such regulations, aiming to address discrepancies in the airworthiness life limitations of certain helicopter components.
Scope and Application
The Civil Aviation Safety Authority (CASA) has issued an Airworthiness Directive under the Civil Aviation Regulations 1998, specifically targeting the Bell Helicopter Textron Canada (BHTC) Model 206L-4 helicopters. This directive mandates that all operators of the specified helicopters ensure the parts of the collective idler link and collective lever comply with designated airworthiness life limitations, thereby enhancing the safety and reliability of the aircraft. The directive applies to the collective idler link and collective lever components, requiring operators to verify part numbers and assign the correct corresponding retirement life. Components that have exceeded their specified hours must be removed from service and replaced with parts that meet the updated life limitations. Additionally, operators are required to re-identify the parts with new part numbers to reflect the correct retirement life. This directive must be adhered to unless the necessary actions have already been completed within 100 hours of time in service after 3 December 1998. The directive became effective on the aforementioned date and is overseen by CASA to ensure compliance and safety in civil aviation.
Key Provisions
The Civil Aviation Regulations 1998 (Cth), as outlined in Part 39 - 105, mandate specific requirements for the airworthiness of Bell Helicopter Textron Canada (BHTC) Model 206L-4 helicopters, particularly regarding the collective idler link and collective lever. Section 13/98 specifies that the parts in question must have part numbers that correspond to their proper airworthiness life limitations. Specifically, it requires operators to check the part numbers and assign the appropriate retirement life as per a detailed schedule (sections (a)-(d)). Additionally, it mandates the removal of parts that have reached or exceeded their airworthiness limit and their replacement with serviceable parts (section 2). Furthermore, the re-identification of the collective idler link and collective lever with a retirement life of 4800 hours to new part numbers is required (section 3). Compliance with these directives must be achieved within 100 hours of the helicopter being in service after 3 December 1998.
Operators of BHTC Model 206L-4 helicopters are subject to specific obligations under these regulations. They must ensure that the part numbers of the collective idler link and collective lever match the appropriate airworthiness life limitations. This involves checking the part numbers against the provided schedule, removing and replacing parts that have exceeded their service life, and re-identifying certain parts with new part numbers as outlined in the regulations. Failure to comply with these directives within the specified timeframe can result in non-compliance with civil aviation safety standards.
Failure to adhere to the requirements set forth in the Airworthiness Directives can result in severe consequences. While the specific civil or criminal penalties are not detailed in the text, non-compliance with aviation safety regulations can lead to significant legal repercussions. Operators may face fines, enforcement actions, or even the grounding of their aircraft, which could result in substantial financial and operational disruptions. It is imperative that operators strictly follow the directives to avoid these potential penalties.
