AD/BELL 205/21 - Swashplate Scissors Lever Bolts - Inspection

Overview

The Civil Aviation Regulations 1998, amended under the Civil Aviation Act 1988, serve as a comprehensive framework for ensuring the safety and efficiency of civil aviation in Australia. Among these regulations, Part 39 focuses on the maintenance and airworthiness of aircraft, with specific directives addressing various models and components. One such directive, AD/BELL 205/21, pertains to Bell Helicopter Textron 205 Series helicopters, specifically mandating the inspection of swashplate scissors lever bolts. This directive was introduced to address identified safety concerns related to the swashplate mechanism in certain Bell 205A-1 helicopters, ensuring they meet required safety standards. The Australian Government, through its civil aviation regulatory body, aims to maintain high safety standards and mitigate risks associated with aviation operations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the maintenance and safety standards for civil aircraft within Australia, and this particular legislative instrument, F2006B04362, pertains to the Bell Helicopter Textron 205 Series Helicopters. This regulation applies to all model 205A-1 helicopters with serial numbers ranging from 30001 to 30169. The directive, AD/BELL 205/21, mandates that a specific inspection of the swashplate scissors lever bolts must be performed within 25 hours of time in service after 16 September 1974. This requirement is detailed in Bell SB No. 205-(04-2)-74-1. The scope of this legislation is limited to the specified model and serial number range of the Bell Helicopter Textron 205 Series, ensuring that these aircraft meet the necessary safety standards set by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, particularly within Part 39 - 105, include specific directives regarding the airworthiness of aircraft, with Section AD/BELL 205/21 focusing on the inspection of swashplate scissors lever bolts for Bell Helicopter Textron 205 Series helicopters. This directive applies to all model 205A-1 helicopters with serial numbers ranging from 30001 to 30169. The requirement is to comply with Bell Service Bulletin No. 205-(04-2)-74-1, which mandates an inspection of the swashplate scissors lever bolts within 25 hours of time in service after the directive was issued on 16 September 1974. This means that operators of these specific helicopters must ensure that the specified components are inspected within this timeframe to maintain the airworthiness of the aircraft. The obligations imposed by this directive are clear and specific. Operators of the affected Bell Helicopter Textron 205 Series helicopters must adhere to the stipulated inspection procedure outlined in Bell Service Bulletin No. 205-(04-2)-74-1. This involves detailed checks and maintenance of the swashplate scissors lever bolts, ensuring they meet the necessary safety standards. Compliance with this directive is critical as it directly impacts the operational safety of the aircraft and the personnel onboard. Failure to meet these requirements could potentially compromise the structural integrity of the helicopter, leading to serious safety hazards. Failure to comply with the provisions of AD/BELL 205/21 can result in significant consequences. While the Civil Aviation Regulations do not explicitly detail specific penalties within this particular directive, non-compliance with airworthiness directives generally can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Such actions may include administrative penalties, which can be substantial, as well as potential criminal charges for individuals responsible for the oversight of the aircraft. In severe cases, the operation of the non-compliant aircraft could be prohibited, which would have significant implications for the operator, including financial losses and reputational damage. Additionally, operators must maintain thorough documentation of the inspections and any subsequent maintenance work performed on the swashplate scissors lever bolts. This documentation is essential for demonstrating compliance with the directive and must be readily available for inspection by CASA. This requirement ensures transparency and accountability, allowing regulatory bodies to verify that the safety standards are being met. Any discrepancies or failures to document the required inspections could also lead to enforcement actions and additional penalties. Overall, the directive under Section AD/BELL 205/21 of the Civil Aviation Regulations 1998 is a critical component in ensuring the safety and airworthiness of the specified Bell Helicopter Textron 205 Series helicopters. Operators must rigorously adhere to the outlined inspection procedures and maintain comprehensive records to avoid the severe consequences associated with non-compliance.
