AD/BELL 212/22 - Tail Rotor Drive Shaft - Replacement

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority, form a critical part of Australia's regulatory framework for civil aviation, ensuring safety and efficiency within the sector. Specifically, Part 39 - 105 within these regulations addresses the issuance of Airworthiness Directives, which are legally enforceable rules to correct an unsafe condition on an aircraft. The directive pertaining to the Bell Helicopter Textron 212 Series Helicopters, identified as AD/BELL 212/22, was introduced to address a safety issue concerning the tail rotor drive shaft of the Model 212 helicopters. This was enacted to mitigate the risk associated with potential failure of the tail rotor drive shaft, thereby enhancing the overall safety of these aircraft. The directive applies to Model 212 helicopters with specific serial numbers and requires compliance within 200 hours of time in service after 30 September 1978. The overarching policy objective is to ensure the safety of air operations by mandating the replacement of the tail rotor drive shaft to prevent potential catastrophic failures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, addresses the maintenance and operational standards for aircraft within Australia. The regulations pertain to Bell Helicopter Textron 212 Series Helicopters, more precisely those with serial numbers ranging from 30501 to 30863, and 30865. These regulations mandate the replacement of the tail rotor drive shaft in compliance with Bell SB 212-78-7, and require that this action be taken within 200 hours of time in service following 30 September 1978. This directive applies to all operators and owners of the specified helicopter models, ensuring safety and airworthiness standards are consistently met across the industry. The application of these regulations is national in scope, overseen by the Civil Aviation Safety Authority, ensuring uniformity in compliance throughout the Commonwealth. The regulations do not specify any exclusions or exemptions, applying uniformly to all relevant aircraft within the designated serial number range.

Key Provisions

The Civil Aviation Regulations 1998 (CAR) under Part 39, particularly the section concerning the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, sets forth specific requirements for the airworthiness of certain aircraft models, including the Bell Helicopter Textron 212 Series Helicopters. Section AD/BELL 212/22 pertains to the tail rotor drive shaft replacement of these helicopters, with applicability to model 212 helicopters that have serial numbers (S/Nos.) ranging from 30501 to 30863, and 30865. The directive mandates compliance with the guidelines outlined in Bell SB 212-78-7 and requires that the specified maintenance action be completed within 200 hours of time in service after 30 September 1978. The obligations under this directive are clear and directive. Operators of the affected Bell Helicopter Textron 212 Series Helicopters must ensure that the tail rotor drive shaft replacement is carried out as per the specified documentation (Bell SB 212-78-7). This involves a comprehensive inspection and, if necessary, replacement of the tail rotor drive shaft to maintain the airworthiness of the aircraft. The compliance period is stringent, requiring that this action be completed within 200 hours of time in service after the directive was issued, which was 30 September 1978. Failure to comply with the provisions of this airworthiness directive can lead to severe consequences. CASA has the authority to enforce these regulations, and non-compliance can result in significant penalties. The Civil Aviation Act 1988 provides for both civil and criminal penalties for breaches of aviation safety regulations. Civil penalties can include fines of up to $210,000 for individuals and $1,050,000 for corporations, as stipulated under section 48 of the Act. In more severe cases, criminal penalties can apply, with maximum fines of up to $525,000 for individuals and $2,625,000 for corporations, alongside potential imprisonment. These stringent penalties underscore the importance of adhering to the airworthiness directives to ensure the safety and compliance of aviation operations.
