Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, addresses safety directives related to aircraft, including the Bell Helicopter Textron 212 Series Helicopters. Enacted by the Commonwealth of Australia, these regulations were introduced to ensure that all civil aviation operations comply with stringent safety standards. The policy objective is to mitigate risks associated with aircraft maintenance and operations, particularly focusing on the structural integrity of components such as the main rotor grip/blade bolt. The Civil Aviation Safety Authority is responsible for issuing airworthiness directives to enforce compliance with these regulations. In this context, the legislation mandates that all Bell Helicopter Textron 212 Series Helicopters with reworked grips that had bushings replaced must adhere to specific inspection and rework requirements as outlined in Bell Alert S.B. No. 212-85-37.3/85. This directive aims to address the problem of improper clearance between the blade bolt head flange and the grip bushing, which has been identified in previously repaired grip assemblies.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertain to airworthiness directives issued by the Civil Aviation Safety Authority (CASA) concerning the Bell Helicopter Textron 212 Series Helicopters. This legislation applies to all Bell Helicopter Textron 212 Series helicopters with main rotor grip assemblies that have undergone rework by Bell Helicopter Textron International (BHTI) and had their grip bushings replaced. The requirement, detailed in Bell Alert S.B. No. 212-85-37.3/85, mandates inspections and necessary rework of these main rotor grip/blade bolt assemblies. Compliance with this directive is essential within 100 hours of time in service after 31 March 1985 or at the next scheduled inspection for maintenance release issued after that date, whichever is later. This regulation underscores CASA's commitment to ensuring the safety and airworthiness of helicopters operating within Australian airspace, addressing specific issues reported with improper clearances between blade bolt head flanges and grip bushings in reworked assemblies.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically within the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, addresses the inspection and rework requirements for Bell Helicopter Textron 212 Series Helicopters. Specifically, AD/BELL 212/33 pertains to the main rotor grip/blade bolt, demanding particular attention to the grip bushing (section (1)). The requirement is outlined in Bell Alert S.B. No. 212-85-37.3/85, which mandates that all Bell Helicopter Textron 12 Series Helicopters with reworked grips having replaced grip bushings must adhere to these provisions (section (2)). These requirements necessitate that the inspection and rework of the main rotor grip/blade bolt must be completed within 100 hours of time in service after 31 March 1985, or at the next scheduled inspection for maintenance release issued after 31 March 1985, whichever is later (section (3)). This timeline is crucial for ensuring that the identified issues, such as improper clearance between the blade bolt head flange and the grip bushing, are rectified in a timely manner to maintain airworthiness and safety standards. The obligations imposed by this directive are clear and must be strictly followed by all parties involved. Operators of Bell Helicopter Textron 12 Series helicopters must ensure that the specified inspections and reworks are conducted on the main rotor grip/blade bolt within the prescribed timeframes. This involves detailed checks and necessary rework of the grip bushings to prevent any clearance issues that could compromise the safety of the aircraft. Failure to comply with these obligations could lead to serious safety hazards and potential regulatory consequences. Non-compliance with the provisions outlined in AD/BELL 212/33 may result in significant legal and safety repercussions. The Civil Aviation Safety Authority has the authority to impose penalties for breaches of these regulations. The exact nature and severity of these penalties can vary, but they may include fines, suspension or revocation of airworthiness certificates, and other enforcement actions. The maximum penalties, as stipulated by the regulations, can be substantial, reflecting the critical nature of ensuring airworthiness and safety in aviation operations.
