Overview
The Airworthiness Directives 2004 were enacted by David Alan Villiers, acting as a delegate of the Civil Aviation Safety Authority (CASA), under subregulation 39.001 (1) of the Civil Aviation Safety Regulations 1998. This legislative instrument revokes and re-makes a series of airworthiness directives concerning Kawasaki BK 117 series helicopters, addressing various maintenance and safety issues. The objective of this legislative action was to ensure the safety and airworthiness of these helicopters by updating and reaffirming necessary safety protocols and standards, thereby aligning them with current regulatory requirements and industry best practices. Each airworthiness directive is re-made in the same form as it appears in the latest published edition, ensuring consistency and clarity for those responsible for the maintenance and operation of these aircraft.
Scope and Application
The Airworthiness Directives 2004, made under the Civil Aviation Safety Regulations 1998 by the delegate of the Civil Aviation Safety Authority, apply specifically to the operation, maintenance, and airworthiness of Kawasaki BK 117 series helicopters. These directives are designed to ensure the safe operation of these aircraft by mandating compliance with detailed technical standards and maintenance requirements for various helicopter components. The geographic reach of these directives is national, as they apply to all Kawasaki BK 117 series helicopters operating within Australia. The directives are enforceable across all states and territories, ensuring a consistent approach to airworthiness standards throughout the country. The legislation revokes and re-makes various specific Airworthiness Directives related to the maintenance and operation of these helicopters, such as those concerning tail rotor blade bonding, cowlings, electrical bonding, and the main rotor blade, among others. Each directive is re-made in the same form as the latest published edition, ensuring that the most current safety standards are applied. While the primary focus is on enhancing safety and airworthiness, there are no explicit exclusions or exemptions mentioned within the scope of this legislative instrument.
Key Provisions
This legislative instrument, the Airworthiness Directives 2004, involves the revocation and remaking of several Airworthiness Directives pertaining to the Kawasaki BK 117 Series Helicopters. As a delegate of the Civil Aviation Safety Authority, David Alan Villiers revokes specific Airworthiness Directives listed in Schedule 1 and concurrently re-issues them as separate instruments, ensuring they match the latest published editions. The directives, each with specific AD names and numbers, cover a range of maintenance and operational requirements such as tail rotor blade bonding, retirement life of critical components, cowlings, electrical bonding, and various rotor and engine-related issues.
The Airworthiness Directives impose stringent obligations on the holders and operators of the Kawasaki BK 117 Series Helicopters. These directives mandate specific maintenance actions, inspections, and operational procedures to ensure the airworthiness of the aircraft. For example, operators must adhere to the specified inspection intervals and repair or replace components as detailed in the directives. Compliance is essential to maintain the safety standards set by the Civil Aviation Safety Authority and to ensure that the aircraft remain airworthy throughout their operational life.
Failure to comply with the requirements set forth in the Airworthiness Directives can result in significant legal consequences. The Civil Aviation Safety Regulations 1998, under which these directives operate, outline various offences and penalties for non-compliance. In particular, violations of airworthiness directives can lead to criminal charges, with potential penalties including fines and imprisonment. The exact penalties depend on the severity of the breach and the specific provisions of the regulations, but they underscore the critical importance of adhering to the directives to avoid serious repercussions.
