AD/BELL 206/46 Amdt 1 - Tailboom Skin Splice - Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, form the legal framework governing aviation safety in the country. A key element of these regulations is the Civil Aviation Safety Authority Schedule of Airworthiness Directives, which was introduced to ensure that aircraft are maintained and operated in a safe and reliable manner. Part 39 - 105 specifically pertains to the airworthiness directives for various aircraft models, ensuring they meet stringent safety standards. One such directive, AD/BELL 206/46 Amendment 1, addresses the inspection of the tailboom skin splice on Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series helicopters, specifically for models AB206A, AB206B, 206A, and 206B prior to serial number 945. The directive was issued to address potential safety issues identified with the tailboom skin splice and mandates inspections at intervals not exceeding 100 hours of service after the directive's issuance on 29 March 1974. Compliance with this directive is crucial to maintaining the structural integrity and operational safety of the specified helicopter models.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to airworthiness directives issued by the Civil Aviation Safety Authority (CASA) and applies to all relevant stakeholders including aircraft manufacturers, operators, and maintenance providers within the aviation industry. This particular legislative instrument, AD/BELL 206/46 Amendment 1, mandates inspections of the tailboom skin splice for all models AB206A and AB206B, as well as 206A and 206B helicopters prior to serial numbers 945, ensuring compliance with the specified intervals not exceeding 100 hours of time in service following 29 March 1974. This directive is rooted in Bell SB 206-01-73-4, Revision B, with cross-reference to Agusta SB No. BT206-62, underscoring the jurisdictional reach across the Commonwealth of Australia and emphasising the need for strict adherence to the outlined safety measures to maintain airworthiness standards.

Key Provisions

The Civil Aviation Regulations 1998 (Cth) under Part 39, Section 105, contain specific Airworthiness Directives (ADs) for various aircraft models, including the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 series helicopters. In this case, the AD/BELL 206/46 Amendment 1 pertains to the inspection of the tailboom skin splice (Section 3/74). This directive applies to all models AB206A and AB206B, 206A and 206B prior to serial numbers 945. The directive requires compliance with the instructions detailed in Bell SB 206-01-73-4, Revision B, and notes that Agusta SB No. BT206-62 is also relevant. The primary obligation under this directive is the requirement for inspections to be conducted at intervals not exceeding 100 hours of time in service following the directive's issuance date of 29 March 1974. This ensures that the tailboom skin splices are checked for any signs of wear, damage, or other issues that could compromise the aircraft's structural integrity. Compliance with these inspection intervals is mandatory for the specified helicopter models to maintain their airworthiness certification and to ensure safety in operations. Failure to adhere to the stipulated inspection intervals and the subsequent identification and rectification of any issues found during these inspections can lead to serious consequences. Non-compliance with the Airworthiness Directives can result in the grounding of the aircraft until the necessary repairs are completed and approved by the Civil Aviation Safety Authority (CASA). This could lead to operational disruptions and financial losses for the operator. Additionally, the non-compliance may attract civil or criminal penalties under the Civil Aviation Act 1988 (Cth), including fines and potential imprisonment for individuals found guilty of violations. Specifically, under the Civil Aviation Act 1988 (Cth), there are provisions for penalties for non-compliance with ADs. For corporate entities, the maximum penalty can include fines up to $210,000 for each occurrence of non-compliance. For natural persons, the maximum penalty can include fines up to $42,000 and/or imprisonment for up to two years for each occurrence. These penalties underscore the importance of adhering to the regulatory requirements set forth in the Civil Aviation Regulations 1998 and the specific ADs to ensure the safety and airworthiness of the aircraft.
