AD/AMD 50/15 - Take-Off Configuration Warning

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA) and enacted by the Australian Parliament, serve as a comprehensive framework for ensuring the safety and efficiency of civil aviation within Australia. Within this framework, Part 39 focuses on airworthiness directives, which are regulatory measures designed to maintain the airworthiness of aircraft. The particular legislative instrument F2006B02382, concerning the Falcon 50 and 900 series aeroplanes, was introduced to address a safety concern related to the take-off configuration warning system. This directive was necessitated to ensure that specific Falcon 50 aeroplanes, identified by their serial numbers and the absence of particular modifications, comply with safety standards by implementing a modification to the take-off warning system as per Dassault Aviation Service Bulletin F50-240 dated 5 April 1995. The policy objective behind this measure is to enhance flight safety by providing clear and reliable warnings during the take-off phase.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the safety directives issued by the Civil Aviation Safety Authority (CASA) for ensuring the airworthiness of aircraft within Australia. One such directive, AD/AMD 50/15, applies exclusively to Mystère Falcon 50 aeroplanes with serial numbers 252, 250, and below, unless they have already incorporated Modification No F50 M1850 or Dassault Aviation Service Bulletin F50-240. This particular Airworthiness Directive mandates that the take-off warning system of the specified Falcon 50 aeroplanes must be modified according to Dassault Aviation Service Bulletin F50-240 dated 5 April 1995. The directive, referencing DGAC AD 98-300-022(B), requires compliance before 8 May 1999 and became effective on 5 November 1998. The directive ensures that the ‘T/O CONFIG’ light on the warning panel will illuminate when the aircraft is on the ground with the park brake not released and at least one of the power levers set at full power. This regulatory measure is essential for maintaining the safety standards of civil aviation in Australia.

Key Provisions

The primary operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, detail the requirements for airworthiness directives concerning certain aircraft models. Section 39.105(1) mandates that modifications be made to the take-off warning system of Mystère Falcon 50 aeroplanes with specific serial numbers to ensure compliance with safety standards. This directive applies to aeroplanes with serial numbers 252, 250, and below unless they already have the Modification No F50 M1850 or Dassault Aviation Service Bulletin F50-240 incorporated. The directive requires the take-off warning system to be modified in accordance with Dassault Aviation Service Bulletin F50-240 dated 5 April 1995, as noted in DGAC AD 98-300-022(B). Compliance with this directive must be achieved before 8 May 1999. The Civil Aviation Regulations impose several obligations on the entities governed by this airworthiness directive. Operators of the affected Mystère Falcon 50 aeroplanes must ensure that the specified modifications are completed by the compliance date. This involves updating the take-off warning system to meet the criteria outlined in the Dassault Aviation Service Bulletin F50-240. Operators must also maintain records of compliance and be prepared to demonstrate adherence to the directive during inspections by the Civil Aviation Safety Authority (CASA). Failure to comply with these obligations may result in regulatory actions. Failure to adhere to the requirements set forth in the airworthiness directive can lead to various civil and criminal consequences. Under Section 97(1) of the Civil Aviation Act 1988, non-compliance with airworthiness directives can result in enforcement actions by CASA, including fines and potential grounding of the affected aircraft. The specific penalties for breaches of this directive can vary but may include substantial financial penalties. For example, under the Civil Aviation Regulations, penalties for non-compliance with airworthiness directives can reach up to $300,000 for corporations and $60,000 for individuals, depending on the severity of the breach. Additionally, repeated or severe breaches may lead to more severe consequences, such as suspension or revocation of the aircraft's certificate of airworthiness.
