Overview

The Civil Aviation Regulations 1998, as amended, encompass a comprehensive framework designed to ensure the safety and airworthiness of aircraft operating within Australia. One particular legislative instrument, F2006B04335, issued by the Civil Aviation Safety Authority (CASA), addresses specific safety concerns associated with certain models of helicopters. Enacted in 2000, this Airworthiness Directive (AD) targets the Bell Helicopter Textron 204 Series Helicopters, specifically focusing on the tail rotor grip to prevent potential failures that could compromise flight safety. The directive mandates the removal from service of certain tail rotor grips that exceed a specified service hour limit or where the total service time cannot be verified. This legislative measure was introduced to rectify identified safety issues and aligns with the overarching policy objective of maintaining high safety standards in civil aviation.

Scope and Application

The Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998 specifically applies to Bell Helicopter Textron 204 Series Helicopters, more precisely those models identified as 204B with tail rotor grips P/N 204-011-728-1, -13, or -19 installed. The directive mandates the removal of such tail rotor grips from service under two conditions: if they have accumulated more than 300 hours of operational time, or if the total time in service cannot be determined. This requirement must be met before further flight after the directive's effective date, which was set as 10 August 2000. The directive was issued by a delegate of the Civil Aviation Safety Authority (CASA) and aims to prevent potential failures of the tail rotor grips. The directive was also referenced in FAA AD 88-25-05, indicating a coordinated approach with international safety standards. The AD applies across the Commonwealth of Australia and was formally notified in the Commonwealth of Australia Gazette on 12 July 2000.

Key Provisions

The main operative sections of this Airworthiness Directive (AD/BELL 204/32) pertain to the applicability (1), requirement (2), and compliance (3) of the directive. According to section (1), the directive applies to Bell Helicopter Textron 204 Series helicopters with tail rotor grip P/N 204-011-728-1, -13, or -19 installed. Section (2) requires that any tail rotor grip with more than 300 hours of time in service, or any where total time in service cannot be established, must be removed from service. Section (3) mandates that this action must be taken before further flight after the effective date of the directive, which is 10 August 2000. The obligations imposed by this Airworthiness Directive on the parties governed by it are primarily focused on ensuring the safety of the aircraft in question. Owners and operators of the affected Bell Helicopter Textron 204 Series helicopters must identify if their aircraft falls under the applicability section of the directive. If it does, they must take the necessary actions as specified in the requirement section, which involves removing the specified tail rotor grips from service. Additionally, the compliance section demands that this action be completed before any further flight occurs after the effective date of the directive. Failure to comply with this Airworthiness Directive may result in civil and criminal consequences. The Civil Aviation Regulations 1998 provide for penalties for non-compliance with airworthiness directives. In civil terms, this may include fines or other penalties imposed by the Civil Aviation Safety Authority (CASA). Criminally, non-compliance with airworthiness directives can lead to prosecution, which may result in fines and imprisonment. The exact penalties are not specified in the text, but they can be severe, reflecting the importance of ensuring aircraft safety.
