AD/SD3-60/32 - Main Wheel Tyres

Overview

The Civil Aviation Regulations 1998, as amended, include a legislative instrument aimed at ensuring the airworthiness of aircraft, particularly focusing on safety directives related to specific models and components. This particular legislative instrument, identified as F2006B06877, was enacted to address issues of premature failure of main landing gear tyres on specific aircraft models, particularly the SD3-60 Series 300 and certain serial numbers. This initiative was introduced to rectify a gap in safety protocols by mandating actions in line with a specified service bulletin issued by Dunlop Limited, thereby ensuring the continued safety and airworthiness of the affected aircraft. The instrument was enacted by the Australian Government to maintain high safety standards in civil aviation, aligning with the overarching policy objective of protecting public safety and maintaining the integrity of civil aviation operations.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, pertains to the maintenance and operation of aircraft in Australia. This particular legislative instrument, AD/SD3-60/32, addresses the issue of main wheel tyre specifications for the SD3-60 Series 300 aircraft, as well as specific aircraft serial numbers (SH3708, SH3712, SH3713, SH3714, SH3715). The directive mandates compliance with the Mandatory Dunlop Limited Service Bulletin 32-1044, with a noted effectivity date of 18 April 1991 for aircraft registered in Australia. The legislation targets the aviation industry, focusing on operators and owners of the specified aircraft models to ensure safety standards are met. Geographic reach is national, as the Civil Aviation Regulations are applicable across Australia. There are no stated exclusions or exemptions in this directive, and compliance is necessary for the specified aircraft to maintain their airworthiness. The scope of this directive is limited to the specified aircraft and does not extend to other models or types unless otherwise specified in subordinate instruments or additional directives.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, detail the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, including AD/SD3-60/32, which addresses main wheel tyre issues for the SD3-60 Series 300 aircraft and certain serial numbers. The directive mandates that actions be taken in accordance with the Mandatory Dunlop Limited Service Bulletin (SB) 32-1044. This requirement is aimed at addressing the premature failure of main landing gear tyres, part number DR19922T, which has been an issue in these specific aircraft models. These regulations impose specific obligations on the parties and entities governed by the Act. Operators of the SD3-60 Series 300 aircraft and those with the mentioned serial numbers are required to follow the outlined action plan, as specified in the Requirement Document. A key obligation is to ensure that the necessary maintenance and compliance checks are carried out, with the revised effectivity date of 18 April 1991 for Australian registered aircraft. This means that the actions specified in the Dunlop Limited SB 32-1044 must be implemented by this date, ensuring that the aircraft meet the necessary safety standards. Failure to comply with the provisions of AD/SD3-60/32 can result in serious consequences. Civil penalties can be imposed for non-compliance, as outlined in the Civil Aviation Regulations. These penalties can include fines, which may be substantial depending on the severity and frequency of the non-compliance. Additionally, continued operation of non-compliant aircraft could lead to further regulatory action, including grounding of the aircraft until compliance is achieved. In severe cases, criminal charges could also be brought against individuals or entities responsible for the non-compliance, leading to potential imprisonment and higher fines. Therefore, it is critical for operators to adhere strictly to the specified directives to avoid these legal and financial repercussions.
