Overview
The Civil Aviation Safety Regulations 1998, enacted by the Commonwealth of Australia, aim to ensure the safety of civil aviation in Australia. This legislation addresses gaps in aircraft safety standards by providing a framework for the Civil Aviation Safety Authority (CASA) to issue Airworthiness Directives (ADs) to correct unsafe conditions. Part 39 of these regulations outlines specific ADs that must be followed by aircraft operators to maintain airworthiness. The policy objective of this regulatory framework is to enhance the safety of civil aviation by mandating regular inspections and corrective actions for identified safety issues. This particular AD, issued under subregulation 39.1(1), focuses on the inspection of stub wing shear decks in SD3-60 series aeroplanes to address reported corrosion and wear, ensuring that aircraft remain airworthy and compliant with safety standards.
Scope and Application
The Civil Aviation Safety Regulations 1998, specifically Part 39 - 105, applies to all SD3-60 aircraft except those which have the Service Bulletin SD360-32-35 incorporated. The regulations are enacted under the authority of the Commonwealth of Australia and are enforced by the Civil Aviation Safety Authority (CASA). The scope of this particular Airworthiness Directive (AD) targets the inspection of stub wing shear decks for signs of corrosion or wear as identified in Short Brothers Service Bulletin SD360-53-42 Revision 1. This directive mandates that inspections must be conducted according to the specified instructions in the requirement section, with compliance dates set as either before 30 April 1997 if the initial inspection has not yet been accomplished, or as per the timeline outlined in the Requirement Document thereafter. The directive was amended on 2 October 2003 to include references to approved oversize bushes and to clarify the retention of pins and circlips, and this amendment remains effective as per the compliance schedule.
Key Provisions
The Civil Aviation Safety Regulations 1998 (CASR 1998), specifically within Part 39, include a detailed Airworthiness Directive (AD) for certain aircraft. This AD, which is aimed at ensuring the safety of Short SD3-60 series aeroplanes, was issued under subregulation 39.1(1). The directive revokes an earlier AD (AD/SD3-60/45) and introduces new requirements in response to identified issues with the stub wing shear decks. The directive applies to all SD3-60 aircraft, excluding those that have already incorporated Service Bulletin SD360-32-35. The primary requirement is for an inspection of the aircraft in accordance with Short Brothers Service Bulletin SD360-53-42 Revision 1, with further actions potentially necessary for aircraft that had complied with a previous requirement document.
The AD imposes specific obligations on the owners and operators of the affected aircraft. They must ensure that the inspection is conducted according to the specified bulletin, with the initial inspection to be completed before 30 April 1997 if not already done. Further inspections must then adhere to the schedule outlined in the requirement document, continuing until Service Bulletin SD360-32-35 is incorporated. These obligations are crucial to maintaining the airworthiness of the aircraft and ensuring compliance with safety standards.
Failure to comply with the requirements of this Airworthiness Directive can result in significant legal consequences. The regulations under which this AD is issued empower the Civil Aviation Safety Authority (CASA) to take enforcement actions against non-compliance. While the specific penalties are not detailed in the text, breaches of CASR 1998 can lead to civil or criminal penalties, depending on the severity of the violation. Such penalties may include fines, imprisonment, or other sanctions as prescribed by law. It is imperative for aircraft operators and owners to adhere to the AD to avoid these potential repercussions and to maintain the safety and airworthiness of their aircraft.
