Overview

The Airworthiness Directives 2004, enacted by David Alan Villiers, delegate of the Civil Aviation Safety Authority, under subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998, addresses the need for updated and consolidated airworthiness directives concerning the Gates Learjet 35 and 36 series aeroplanes. This legislative instrument revokes previously issued airworthiness directives and re-makes them in the same form as the latest published editions. The primary objective is to ensure that the airworthiness directives are current and reflect the latest safety requirements, thereby maintaining the safety and airworthiness of the specified aircraft models. The instrument does not explicitly state a policy objective but implicitly aims at enhancing aviation safety by providing clear, updated directives to aircraft operators and maintenance personnel.

Scope and Application

The Airworthiness Directives 2004, made under the Civil Aviation Safety Regulations 1998, pertain specifically to the airworthiness of the Gates Learjet 35 and 36 series aeroplanes. These directives are issued by the delegate of the Civil Aviation Safety Authority, David Alan Villiers, who acts under the authority conferred by subregulation 39.001(1) of the Civil Aviation Safety Regulations 1998. The directives revoke previously issued airworthiness directives and re-make them in a manner that is identical to the latest published editions. The scope of the legislation applies to the specified aircraft models, mandating specific inspections, modifications, and replacements to ensure compliance with airworthiness standards. This regulatory action ensures that the aircraft maintain their airworthiness and safety in accordance with the latest safety requirements and technological advancements. The legislation extends its reach to all parties involved with the operation, maintenance, and modification of the affected aircraft, ensuring that all relevant entities adhere to the stipulated airworthiness directives.

Key Provisions

The primary operative sections of this legislative instrument, F2006B07879, involve the revocation and remaking of certain Airworthiness Directives (ADs) for Gates Learjet 35 and 36 series aeroplanes, as outlined in Schedule 1. Specifically, section 2 revokes the listed ADs, and section 3 re-makes these directives as separate instruments, ensuring they appear in the latest published edition of the ADs (section 2 and 3). The directives themselves, which are attached to the legislative instrument, detail various inspections, replacements, modifications, and installations necessary for maintaining the airworthiness of these aircraft. The obligations imposed by this Act are centred around compliance with the re-made ADs. Operators and owners of Gates Learjet 35 and 36 series aeroplanes must adhere to the specific requirements set out in these directives. This includes conducting necessary inspections, replacements, and modifications on various aircraft components such as the primary control system stop bolts, spoiler centre hinge brackets, and cabin altitude pressure limiter, among others (AD/LEARJET 35/1 to AD/LEARJET 35/39). Failure to comply with these ADs could result in the aircraft being deemed unairworthy, leading to potential safety hazards. In terms of enforcement and consequences, breaches of these ADs can lead to serious civil and criminal penalties. Although the specific penalties are not detailed in the legislative instrument itself, under the Civil Aviation Safety Regulations 1998, non-compliance can result in substantial fines and potential imprisonment for individuals found guilty of serious offences. The severity of the penalties often correlates with the degree of negligence or recklessness involved in the breach, and the potential impact on aviation safety. Operators found in violation of these ADs may also face operational restrictions or even the grounding of their aircraft until compliance is achieved.
