AD/AC/52 - Pilot Compartment Side Windows - Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve as a comprehensive regulatory framework designed to ensure the safety and efficiency of civil aviation within the country. Among various provisions, Part 39 - 105 specifically addresses Airworthiness Directives, which are legally enforceable rules related to the design, production, maintenance, and operation of aircraft. One such directive, AD/AC/52, pertains to the replacement of pilot compartment side windows on Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) series aeroplanes. This directive was introduced to address safety concerns related to the structural integrity and functionality of the side windows on specified models, ensuring that they meet the necessary safety standards to protect pilots and passengers alike. The policy objective behind these regulations is to maintain the highest safety standards in civil aviation, thereby protecting the public and enhancing the overall safety of air travel in Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the application of airworthiness directives issued by the Civil Aviation Safety Authority (CASA) in relation to the maintenance and operation of certain aircraft. This regulation applies to all Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600 and 700) series aeroplanes, with a particular focus on model 690A with specific serial numbers ranging from 11102 to 11107 and 11109 to 11116. The regulation mandates that compliance with the airworthiness directive concerning the replacement of pilot compartment side windows must be achieved within 100 hours of time in service after 22 October 1973 or before 1 January 1974, whichever comes first. This directive ensures that specified aircraft meet the necessary safety standards for operation within Australian airspace. The regulations extend their reach across the Commonwealth, impacting all relevant entities and individuals involved in the maintenance and operation of these aircraft within Australia.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines the requirements for the airworthiness directives related to certain aircraft models. For the Twin Commander (Gulfstream/Rockwell/Aerocommander 500, 600, and 700) series aeroplanes, AD/AC/52 addresses the replacement of pilot compartment side windows (Section 10/73). This directive applies to all model 690A aircraft with serial numbers ranging from 11102 to 11107 and from 11109 to 11116. Compliance with this directive necessitates replacing the specified side windows according to the guidelines provided in Aero Commander SL No. 270, and the replacement must be completed within 100 hours of time in service after 22 October 1973 or before 1 January 1974, whichever comes first. The Act imposes several obligations and requirements on the parties and entities it governs. Owners and operators of the affected aircraft must ensure that the required side window replacements are carried out by a certified maintenance provider in accordance with the specified schedule. This includes adhering to the timeframes provided and ensuring that the replacements are performed using the correct parts and procedures as outlined in Aero Commander SL No. 270. Failure to comply with these requirements can result in the aircraft being deemed unairworthy, which could lead to severe operational and legal repercussions. Under the Civil Aviation Regulations 1998, non-compliance with the airworthiness directives can result in significant consequences. Operators who fail to adhere to the mandated replacement schedule may face enforcement actions, including fines, penalties, and potential grounding of the aircraft. The regulations are clear that any failure to comply with the airworthiness directives can be treated as a serious breach, with potential maximum penalties imposed as per the legislative framework. These penalties are designed to ensure that aircraft maintain the highest safety standards, thereby protecting both the crew and the passengers.
