AD/AMD 50/8 - Cockpit Brake Pressure Lines

Overview

The Civil Aviation Regulations 1998, which were enacted by the Parliament of Australia, serve to regulate various aspects of civil aviation within Australia. A particular focus of the regulations is the safety of aircraft and their operations, as evidenced by Part 39 - 105 which pertains to the Civil Aviation Safety Authority’s schedule of airworthiness directives. This legislative instrument addresses specific issues and required actions to ensure the safety and reliability of aircraft in operation. One such directive is AD/AMD 50/8 concerning the cockpit brake pressure lines of Falcon 50 and 900 series aeroplanes. This directive was introduced to address the potential problem of chaffing of the cockpit left side brake pressure lines in Falcon 900 aircraft, requiring compliance within 50 hours of time in service from 17 October 1995 unless the specified action had already been performed in accordance with Dassault Aviation Alert Service Bulletin F900-A29-4. The objective of this directive is to prevent possible safety hazards by ensuring the integrity of the brake pressure lines.

Scope and Application

The Civil Aviation Regulations 1998, as amended, include specific provisions within Part 39 concerning airworthiness directives. One such directive, AD/AMD 50/8, pertains to the Falcon 50 and 900 series aeroplanes and addresses the issue of cockpit brake pressure lines. This directive applies to all Falcon 900 aircraft and requires that certain actions be taken to rectify potential issues with chaffing of the cockpit left-hand side brake pressure lines unless these actions have already been implemented in accordance with Dassault Aviation Alert Service Bulletin F900-A29-4. Compliance with this directive is mandatory, with a requirement to address the specified issues within 50 hours of time in service from the directive's effective date of 17 October 1995. The directive's application extends to ensuring the safety and airworthiness of the specified aircraft, thereby maintaining high standards of aviation safety across the Commonwealth.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105, establish the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives (AD) for various aircraft, including the AMD Falcon 50 and 900 series aeroplanes. This part of the regulations mandates certain actions to be taken to ensure the airworthiness of these aircraft. For instance, Airworthiness Directive AD/AMD 50/8, issued on 13th September 1995, pertains to the cockpit brake pressure lines on Falcon 900 aircraft. According to section (13/95), this directive applies to all Falcon 900 aircraft. It requires compliance within 50 hours of time in service from the date of the directive, 17 October 1995, unless the action has already been carried out in accordance with Dassault Aviation Alert Service Bulletin F900-A29-4. Under this regulation, the primary obligation for the operators of Falcon 900 aircraft is to ensure that the cockpit left-hand side brake pressure lines are inspected and, if necessary, modified or replaced. This inspection and action must be completed within the specified timeframe to maintain the airworthiness of the aircraft. The regulation implies that the operator must take proactive steps to review the maintenance records and ensure that any previous actions in line with Dassault Aviation Alert Service Bulletin F900-A29-4 have been documented and implemented. This requirement is crucial to prevent the identified issue of chaffing of the cockpit brake pressure lines, which could compromise safety. Failure to comply with the provisions of the AD/AMD 50/8 can lead to severe consequences. According to the Civil Aviation Regulations 1998, non-compliance with an airworthiness directive can result in serious safety risks, as it may render the aircraft unsafe to operate. Moreover, CASA has the authority to take enforcement actions against operators who fail to comply with airworthiness directives. These actions can include grounding the aircraft until the required actions are completed, issuing fines, or pursuing other legal remedies. The potential penalties for non-compliance underscore the importance of adhering to these regulations to ensure the safety and airworthiness of the aircraft.
