Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, aim to ensure the safety and efficiency of civil aviation within the country. This piece of legislation provides the framework for the regulation of civil aviation, including the operation of aircraft, the maintenance of airworthiness, and the certification of personnel. Specifically, Part 39 - 105 of the Civil Aviation Regulations 1998, addresses airworthiness directives that are issued by the Civil Aviation Safety Authority (CASA) to address safety issues that have been identified in specific aircraft types. The policy objective of these regulations is to ensure that all civil aviation operations in Australia meet the highest possible safety standards, thereby protecting the public and maintaining the integrity of the aviation industry.
In response to a report of "free play" found in the elevator torque shaft assembly bearing housings of Shorts SD3-30 Series Aeroplanes, an Airworthiness Directive was issued under subregulation 39.1 (1) of the Civil Aviation Regulations 1998 by a CASA delegate. The directive mandates that all SD3-30 aircraft must undergo inspection in accordance with a specific service bulletin to correct the unsafe condition caused by incorrect installation of the housings. This Airworthiness Directive, which became effective on 4 October 2001, was designed to ensure the continued airworthiness and safety of the affected aircraft.
Scope and Application
The Airworthiness Directive (AD) issued by the Civil Aviation Safety Authority (CASA) applies specifically to all Shorts SD3-30 series aeroplanes, which must comply with the stipulated inspection requirements as outlined in the directive. The directive mandates an inspection of the elevator torque shaft assembly bearing housings at frame station 74, to be conducted in accordance with the instructions provided in Shorts Mandatory Service Bulletin SD330-27-39. This action is required to rectify an identified unsafe condition related to "free play" due to incorrect installation of the housings, as determined by an investigation following an operator report. The directive came into effect on 4 October 2001, with inspections needing to be completed before 4 December 2001 unless they had already been accomplished, and then repeated as per the Aircraft Maintenance Programme Section 5-25-27. This AD is a legislative instrument under the Civil Aviation Regulations 1998, which operates within the jurisdiction of the Commonwealth of Australia.
Key Provisions
The main operative sections of this Airworthiness Directive (AD/SD3-30/43) for the Shorts SD3-30 Series Aeroplanes require an inspection of the elevator torque shaft assembly bearing housings at frame station 74 in accordance with Shorts Mandatory Service Bulletin SD330-27-39. This action is considered necessary to correct the unsafe condition identified through an operator report of "free play" in the bearing housings, which was determined to be caused by incorrect installation. The AD applies to all SD3-30 aircraft and mandates that this inspection be completed before 4 December 2001 unless it has already been accomplished. After the initial inspection, the requirement must be repeated in accordance with the Aircraft Maintenance Programme Section 5-25-27. This AD became effective on 4 October 2001.
The obligations imposed by this AD on the parties governed by it include conducting a thorough inspection of the specified bearing housings in the elevator torque shaft assembly. This inspection must follow the detailed procedures outlined in Shorts Mandatory Service Bulletin SD330-27-39, ensuring that any issues related to the installation of the bearing housings are identified and rectified. Additionally, operators must complete the inspection before the specified deadline of 4 December 2001, and any subsequent inspections must adhere to the Aircraft Maintenance Programme guidelines. Failure to comply with these obligations could result in the aircraft not being deemed airworthy, leading to potential operational disruptions or legal consequences.
Failure to comply with the AD can result in serious civil and criminal consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce this directive, and non-compliance can lead to penalties under the Civil Aviation Act 1988. The exact nature of the penalties can vary, but they may include fines and other sanctions. In more severe cases, the non-compliance could result in the grounding of the aircraft, preventing it from operating until the required actions are taken. Additionally, CASA may take legal action against individuals or entities responsible for the non-compliance, which could result in further penalties and legal repercussions.
