AD/AMD 50/14 Amdt 1 - Horizontal Stabiliser Hinge

Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITYSCHEDULE OF AIRWORTHINESS DIRECTIVES, was enacted to ensure the safety and airworthiness of aircraft operating within Australian airspace. This legislation, issued by the Commonwealth of Australia, was introduced to address critical safety concerns identified through ongoing assessments and international directives. One such amendment, AD/AMD 50/14, targets specific Falcon 50 and 900 series aeroplanes to rectify issues identified in the horizontal stabiliser hinge, ensuring compliance with stringent safety standards. The policy objective is to maintain and enhance aviation safety by mandating specific modifications and inspections to prevent potential hazards, thereby protecting both passengers and crew. This legislative instrument underscores the importance of adhering to international safety directives and continuous monitoring to mitigate risks. By requiring updates to aircraft manuals and specific maintenance checks, the regulations ensure that operators are aware of and address potential safety issues promptly. The compliance deadlines set forth in the amendment further reinforce the urgency and importance of these safety measures, ensuring that all affected aircraft meet the required standards within specified timeframes.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, pertains to the maintenance and operational requirements of certain Falcon 50 and 900 series aeroplanes. The legislation applies to Mystere Falcon 50 aircraft with serial numbers ranging from 242 through 262, Mystere Falcon 900 aircraft with serial numbers from 139 through 169, and Falcon 900 EX aircraft with serial numbers from 1 through 21. The directive mandates that these aircraft incorporate temporary changes and revisions as specified in the Aircraft Flight Manual and Maintenance Manual. Compliance with these requirements is mandatory, with specific timelines set for various actions, such as performing checks and adhering to service bulletins. This regulation is enforced under the jurisdiction of the Commonwealth of Australia and extends to ensuring the airworthiness and safety of the specified aircraft types within the national airspace.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, contain provisions for airworthiness directives for various aircraft. In the case of the AMD Falcon 50 and 900 series aeroplanes, there is a specific airworthiness directive (AD/AMD 50/14 Amendment 1) that applies to certain serial numbers of these aircraft. The directive mandates several requirements to ensure the continued safety and airworthiness of these aircraft. Firstly, it requires the incorporation of temporary changes and revisions to the Aircraft Flight Manual and the Maintenance Manual for the affected aircraft (section 1). Secondly, it mandates the performance of specific checks outlined in Chapter 5 of the Maintenance Manual at the specified revision status (section 2). Finally, it requires the implementation of actions as per specific Dassault Aviation Service Bulletins relevant to each aircraft model (section 3). The obligations imposed by this airworthiness directive are stringent and time-bound. Operators of Mystere Falcon 50 aircraft with serial numbers 242 through 262, Mystere Falcon 900 aircraft with serial numbers 139 through 169, and Falcon 900 EX aircraft with serial numbers 1 through 21 must ensure that the specified changes and revisions are incorporated into their Aircraft Flight Manual and Maintenance Manual before certain deadlines. For Requirement 1, compliance must be achieved before 23 May 1998. For Requirement 2, compliance is required before 27 February 2004 or after 3750 flight cycles, whichever comes first. For Requirement 3, action must be taken before 6 years and 2 months or after 3750 flight cycles from new, whichever comes first. These obligations underscore the importance of adhering to the schedule to maintain the airworthiness of these aircraft. Failure to comply with the requirements set out in the airworthiness directive may result in civil or criminal consequences. The regulations do not explicitly state the penalties for non-compliance, but non-compliance with airworthiness directives under the Civil Aviation Act 1988 can lead to severe repercussions. This may include fines, penalties, and in extreme cases, criminal charges against individuals or corporations responsible for the non-compliance. Additionally, failure to comply could result in the grounding of the affected aircraft, thereby affecting operational continuity and potentially leading to safety risks. Thus, it is crucial for operators to adhere strictly to the mandated timelines and requirements.
