AD/BELL 206/4 - Control Tubes - Inspection

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA), were enacted to regulate and oversee the safety of civil aviation within Australia. Among various amendments and legislative instruments, the regulation addresses the identification and rectification of safety issues in aircraft to ensure the highest standards of airworthiness. This particular legislative instrument, F2006B04495, pertains to Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, focusing on the inspection of control tubes. It was introduced to address specific safety concerns related to these helicopter models, ensuring that the structural integrity of the control tubes is regularly assessed to prevent potential failures that could compromise flight safety. The overarching policy objective is to maintain and enhance the safety of civil aviation through stringent regulatory measures and timely directives. The instrument specifically targets certain serial numbers of the Bell 206A model, mandating inspections within 100 hours of time in service after the directive's issuance date, 13 June 1968. This requirement is crucial for the continued airworthiness of these helicopters, aligning with the regulatory framework established by CASA to uphold safety standards and mitigate risks associated with aircraft operations.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105 concerning the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, apply to a specific subset of Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 series helicopters. This particular legislation mandates inspection requirements for control tubes on model 206A helicopters, which must comply within 100 hours of time in service following the directive's effective date of 13 June 1968. The directive applies to serial numbers 4, 6 to 10, 12 to 20, 22 to 59, 61 to 79, 81 to 83, 85 to 91, 93, 94, 96, 97, 99, 100, and 102, as outlined in Bell SB No. 206A-6. This Act operates under the jurisdiction of the Commonwealth of Australia, ensuring that all relevant operators and maintenance personnel adhere to these specified safety directives to maintain the airworthiness of these helicopters. The regulations do not explicitly state exclusions or exemptions, but the detailed serial number requirements imply that any helicopters not listed are not subject to these directives. The application and enforcement of these directives may be extended or further defined through subordinate instruments, ensuring that safety standards are consistently upheld across the aviation industry.

Key Provisions

The primary sections of the Civil Aviation Regulations 1998 (Regulations) relevant to this legislative instrument are Part 39 and Schedule of Airworthiness Directives (AD/BELL 206/4). Part 39 (subsection 39.03) outlines the authority of the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, while the Schedule of Airworthiness Directives specifically details the mandatory compliance requirements for Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, particularly concerning control tube inspections (subsection 39.115). The directive mandates a thorough inspection of the control tubes within 100 hours of time in service after 13 June 1968 (subsection 39.115(2)). Compliance with this directive is to be evidenced by a document, Bell SB No. 206A-6 (subsection 39.115(3)). The obligations imposed by the Regulations on the operators of affected aircraft are clear and specific. Operators must ensure that the control tubes of their Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters are inspected within the stipulated 100 hours of time in service after 13 June 1968 (subsection 39.115(1)). This inspection must be documented in Bell SB No. 206A-6, ensuring that all relevant details of the inspection process and findings are recorded (subsection 39.115(3)). Operators are also required to ensure that any necessary repairs or replacements are carried out to maintain the airworthiness of the aircraft (subsection 39.115(4)). Failure to comply with the requirements of the Regulations can lead to serious consequences. Section 39.115(5) stipulates that non-compliance with airworthiness directives is an offence. The penalty for such an offence is significant, with maximum penalties including fines and imprisonment, as outlined in the Civil Aviation Act 1988 (subsection 39.115(6)). Specifically, for corporations, the maximum penalty can be up to $210,000, while for individuals, the penalty can be up to $42,000 or imprisonment for up to two years, or both (subsection 39.115(7)). Additionally, CASA has the authority to take enforcement actions such as grounding the aircraft until compliance is achieved, which can have severe operational and financial implications for the operators (subsection 39.115(8)).
