Overview
The Civil Aviation Regulations 1998, a piece of legislation enacted by the Commonwealth of Australia, includes Part 39, which focuses on Airworthiness Directives. These directives aim to address specific safety issues in the aviation sector. The 1998 regulations were introduced to ensure that all civil aircraft in Australia meet certain safety standards, addressing gaps in previous legislation to improve overall aviation safety. One such directive, AD/SD3-60/60, was issued to address a safety concern identified in Shorts SD3-60 Series Aeroplanes. The directive was enacted by the Civil Aviation Safety Authority (CASA) and aims to correct an unsafe condition related to the elevator torque shaft assembly bearing housings. This directive requires specific inspections to be carried out to ensure that any issues are identified and rectified, thereby enhancing the safety of the aircraft.
Scope and Application
The Airworthiness Directive (AD) issued under the Civil Aviation Regulations 1998 applies specifically to all SD3-60 Series aeroplanes, addressing a safety issue identified in the elevator torque shaft assembly bearing housings. This AD is a legislative instrument issued by the Civil Aviation Safety Authority (CASA) and is applicable nationally within the Commonwealth of Australia. The directive mandates an inspection procedure in accordance with the specified Shorts Mandatory Service Bulletin, and references UK CAA AD 009-05-2001 for additional guidance. The requirement necessitates that the inspection be completed before 4 December 2001, unless already performed, and subsequently according to the Aircraft Maintenance Programme section 5-25-27. The AD became effective on 4 October 2001, and its issuance was notified in the Commonwealth of Australia Gazette on 12 September 2001. The directive does not explicitly mention any exclusions or exemptions, and compliance is mandatory for all SD3-60 aircraft within the Australian jurisdiction.
Key Provisions
The key provisions of the Airworthiness Directive (AD) outlined in the Civil Aviation Regulations 1998, Part 39 - 105, apply specifically to all SD3-60 aircraft. According to section (a), the requirement to inspect the elevator torque shaft assembly bearing housings is mandated in the event of an operator report indicating “free play” at frame Station 74. This inspection must be carried out in accordance with the instructions provided in Shorts Mandatory Service Bulletin SD360-27-31 (section (b)). The inspection must be completed before 4 December 2001, or in accordance with the Aircraft Maintenance Programme section 5-25-27 thereafter (section (c)). The directive became effective on 4 October 2001, as stipulated in the Compliance section.
Operators and owners of SD3-60 aircraft are obligated to ensure that the specified inspections are performed as directed. These obligations include following the inspection procedures laid out in the referenced service bulletin and adhering to the timeline for compliance as outlined in the directive. The AD necessitates that any identified issues are corrected promptly to maintain the airworthiness of the aircraft. Failure to comply with these requirements may result in the aircraft not meeting the necessary safety standards, potentially leading to operational prohibitions or other regulatory actions.
The Civil Aviation Regulations 1998 impose significant consequences for non-compliance with ADs. Any person who fails to comply with the requirements of an AD may be subject to enforcement actions under the Civil Aviation Act 1988. This can include both civil and criminal penalties. Civil penalties may include fines up to $10,000 per occurrence, while criminal penalties can include fines of up to $1,100,000 for corporations and $220,000 for individuals, in addition to potential imprisonment terms. These stringent measures underscore the importance of adhering to ADs to ensure the safety and airworthiness of the aircraft in question.
