AD/MSR/21 - Front Seat Support Beam Protection - Installation

Overview

The Civil Aviation Regulations 1998, as amended, represent a significant legislative framework aimed at ensuring the safety and efficiency of civil aviation within Australia. One such legislative instrument, F2006B11320, introduced specific Airworthiness Directives under Part 39 to address particular safety concerns. This instrument was enacted by the Parliament of Australia to enhance aviation safety through the Civil Aviation Safety Authority (CASA). The policy objective of this legislation is to mandate the installation of specific safety measures to protect against potential hazards identified in certain aircraft models, thereby ensuring the highest standards of airworthiness and passenger safety. One particular directive, AD/MSR/21, pertains to Aerospatiale Rallye Series aeroplanes and requires the installation of a front seat support beam protection cover. This directive was introduced to address the specific issue of ensuring structural integrity and safety within the specified aircraft models. Compliance with this directive is mandatory, requiring the installation within 100 hours of time in service following the directive's issuance on 30 August 1974, to mitigate risks associated with the front seat support beam.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives which govern the airworthiness of aircraft within Australia. One such directive, AD/MSR/21, pertains to Aerospatiale Rallye Series Aeroplanes and mandates the installation of a front seat support beam protection cover. This directive applies to all models within the Aerospatiale Rallye Series, ensuring that the specified safety measure is uniformly implemented across the board. The directive requires compliance within 100 hours of time in service following 30 August 1974, providing a clear timeline for adherence. The directive is enforced under the authority of the Secretary, who approves the scheme according to which the protection cover must be installed, thereby ensuring that the safety standards are met as per the regulatory framework.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandate the installation of front seat support beam protection covers for Aerospatiale Rallye Series Aeroplanes. According to AD/MSR/21 (section 7/74), this directive applies to all models of the Aerospatiale Rallye Series Aeroplanes. The requirement is straightforward: a front seat support beam protection cover must be installed in accordance with a scheme approved by the Secretary. The compliance period for this directive is set at 100 hours of time in service after 30 August 1974. The obligations imposed by this directive are clear and specific. Operators of Aerospatiale Rallye Series Aeroplanes must ensure that the front seat support beam protection cover is installed correctly, adhering to the approved scheme. This involves not only the physical installation but also ensuring that the cover is of a quality and design that meets the regulatory standards set forth by the Secretary. The compliance must be achieved within the specified timeframe, which is 100 hours of operational time following the directive’s effective date of 30 August 1974. Failure to comply with the requirements of AD/MSR/21 could result in serious consequences. The Civil Aviation Regulations 1998 do not explicitly detail the penalties for non-compliance in this particular directive, but generally, non-compliance with airworthiness directives can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). Such actions may include fines, penalties, and in severe cases, grounding of the aircraft until compliance is achieved. The exact penalties would be determined based on the specific circumstances of the non-compliance and the impact on aviation safety.
