AD/MSR/27 Amdt 1 - Corrosion - Inspection

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA) under the authority of the Australian Parliament, includes various amendments and directives to ensure the safety and airworthiness of aircraft. One such amendment is F2006B11326, specifically addressing the inspection of Aerospatiale Rallye Series Aeroplanes to mitigate risks associated with corrosion. This directive was introduced to ensure the integrity of the aircraft's main structures by mandating repetitive inspections and appropriate treatments. The objective of this amendment is to identify and address corrosion at critical stages of the aircraft’s operational life, thereby enhancing the overall safety and reliability of the aircraft in service. The policy objective underpinning this legislation is to provide clear, actionable directives that align with international standards, ensuring that aircraft operations maintain the highest safety benchmarks. The requirement for inspections within specific timeframes aims to preemptively address potential structural issues, thus contributing to the overarching goal of safeguarding both passengers and crew.

Scope and Application

The Civil Aviation Regulations 1998, as amended, encompass various provisions for the safety and regulation of aviation activities within Australia. Specifically, Part 39 - 105 pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, which are regulatory mandates designed to ensure the continued airworthiness of aircraft. One such directive, AD/MSR/27 Amendment 1, targets Aerospatiale Rallye Series Aeroplanes, namely model Rallye MS.880B, MS892, and their derivatives, requiring thorough inspections for corrosion. This regulation applies to all aircraft within the specified models and mandates inspections of areas detailed in Aerospatiale Service Bulletin No. 133/2, Column A. If appreciable spots of corrosion are found, further inspections must be conducted as outlined in Column B of the same bulletin, referencing Bureau Veritas AD 82-89(A). Compliance with this directive requires an initial inspection within 50 hours of the aircraft’s time in service following 27 September 1982, with subsequent inspections scheduled at intervals not exceeding 100 hours of service or every four months, whichever comes first. This ensures the ongoing structural integrity and safety of the aircraft in question.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105 under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, provide detailed guidelines for the inspection and maintenance of Aerospatiale Rallye Series Aeroplanes, specifically models MS.880B and MS892. Section 1 of AD/MSR/27Amdt 1 outlines the primary requirements for these inspections. Firstly, the regulation mandates a thorough inspection of the areas specified in Aerospatiale Service Bulletin No. 133/2 Column A. This ensures that any potential issues are identified and addressed promptly. Should the initial inspection reveal any appreciable spots of corrosion, the inspection scope must be expanded to include the areas listed in Column B of the same service bulletin. This layered inspection approach aims to maintain the structural integrity of the aircraft by ensuring that corrosion does not go undetected. The obligations imposed by these regulations are clear and specific. Operators of the Aerospatiale Rallye Series Aeroplanes must conduct an initial inspection within 50 hours of the aircraft being in service after 27 September 1982. Following this initial inspection, further inspections must occur at intervals not exceeding 100 hours of flight time or four months, whichever comes first. This schedule ensures regular and systematic checks, preventing any deterioration from going unnoticed for extended periods. Compliance with these inspection intervals is crucial to maintaining airworthiness and ensuring the safety of all passengers and crew on board. Failure to adhere to the requirements set forth in AD/MSR/27Amdt 1 can result in severe consequences. The Civil Aviation Regulations 1998 outline various penalties and legal repercussions for non-compliance. If an operator fails to conduct the required inspections at the prescribed intervals, it could result in the aircraft being grounded until the inspections are satisfactorily completed. Furthermore, there may be civil penalties imposed, including fines or other administrative actions. In the most severe cases, persistent non-compliance could lead to criminal charges against the responsible parties, potentially resulting in substantial fines or imprisonment. These stringent measures underscore the importance of adhering to the regulatory requirements to maintain the highest standards of aviation safety.
