AD/OXY/2 - Scott Oxygen Mask Filter Retention - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, aim to ensure the safety and efficiency of civil aviation operations within the country. Specifically, Part 39 - 107 of the Civil Aviation Regulations 1998 includes the Authority’s Schedule of Airworthiness Directives that address various safety concerns related to aircraft systems, including oxygen systems. One such directive, AD/OXY/2, pertains to the modification of Scott Oxygen Mask Filter Retention for certain Sky masks manufactured prior to 8 August 1977. This directive was introduced to address potential safety issues associated with the retention of oxygen mask filters in these specific models. Compliance with this directive is mandatory within 100 hours of time in service after 30 April 1978, as specified in relevant technical documents such as the Scott Installation Instruction dated October 1977, Mitsubishi Service Note 39, or Piper VSP-8. The policy objective behind these regulations is to maintain high safety standards in the aviation industry, ensuring the protection of passengers and crew.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued Airworthiness Directive AD/OXY/2, which applies to specific Sky masks series, namely 28314, 28315, and 28317, that were manufactured prior to 8 August 1977. This regulation mandates modifications to ensure the retention of oxygen mask filters in these specific aircraft oxygen systems to maintain airworthiness. Compliance with this directive is required within 100 hours of time in service following 30 April 1978, and the modifications should adhere to the instructions provided in either the Scott Installation Instruction dated October 1977, Mitsubishi Service Note 39, or Piper VSP-8. This regulation applies to the relevant aircraft and operators within Australia, reinforcing the commitment to aviation safety across the country. The directive is a specific application within the broader framework of the Civil Aviation Regulations 1998, and its enforcement is overseen by CASA. It is part of a series of measures designed to ensure that all aircraft operating within Australia meet the necessary safety standards. The regulation does not explicitly exclude any particular entities or industries, meaning it applies broadly to all relevant aircraft and operators. However, it is also worth noting that the scope and application of this directive can be further extended or clarified through subordinate instruments or additional guidance issued by CASA.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 107, address the issue of airworthiness directives concerning the modification of Scott oxygen mask filters. Section AD/OXY/2 pertains to the retention modification for Scott oxygen masks series 28314, 28315, and 28317 manufactured before 8 August 1977. This directive is crucial for ensuring the safety and reliability of oxygen systems in aircraft. The compliance date for these modifications is set within 100 hours of time in service after 30 April 1978, ensuring that affected aircraft are updated to the required safety standards. The obligations imposed by this airworthiness directive include mandatory modifications to the oxygen mask filter retention systems of the specified Scott masks. Owners and operators of aircraft equipped with these masks must ensure that the modifications are completed as outlined in the Scott Installation Instruction dated October 1977, the Mitsubishi Service Note 39, or the Piper VSP-8. Failure to comply with these directives within the specified timeframe could result in the aircraft being deemed unairworthy, leading to potential grounding and operational disruptions. Breaching the requirements of this airworthiness directive can lead to serious consequences. Non-compliance may result in the aircraft being subject to enforcement actions by the Civil Aviation Safety Authority (CASA). While specific civil or criminal penalties are not detailed in the text, it is clear that failure to adhere to the mandated modifications could lead to significant regulatory penalties, including fines or other sanctions. Additionally, operating an aircraft that does not comply with these safety standards could result in serious safety hazards, potentially leading to severe consequences for passengers, crew, and the aircraft itself.
