COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AMD Fan Jet Falcon (Falcon 20/Mystere-Falcon 200) Series Aeroplanes
AD/AMD 20/24 Engine Cowl Attachment 12/91
Applicability: Mystere-Falcon 200 all serial numbers.
Requirement: Inspect and modify the engine cowl attachments in accordance with the technical requirements of DGAC AD 91-197-018(B).
Compliance: As specified in the Requirement Document with a revised effective date of 12 December 1991 for Australian registered aircraft.
Background: Instances of fatigue cracking have been reported in the engine cowl attachments. These defects could ultimately lead to in-flight loss of the small aprons and hinged cowls. The effective date of the DGAC AD is September 1991. This Directive permits compliance to be deferred two months.
Overview
The Civil Aviation Regulations 1998 were enacted to provide a comprehensive framework for ensuring the safety and efficiency of civil aviation within Australia. This particular legislative instrument, AD/AMD 20/24, was introduced to address safety concerns regarding fatigue cracking in the engine cowl attachments of Mystere-Falcon 200 series aeroplanes, which could potentially lead to in-flight detachment of the small aprons and hinged cowls, posing significant safety risks. The instrument was issued by the Civil Aviation Safety Authority, which sought to ensure compliance with the technical requirements of the Direction Générale de l'Aviation Civile AD 91-197-018(B). The policy objective is to mandate regular inspections and modifications to the engine cowl attachments, with a revised compliance deadline of 12 December 1991 for Australian registered aircraft, allowing a two-month deferment from the original DGAC AD effective date of September 1991.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, mandates that the Airworthiness Directives issued by the Civil Aviation Safety Authority apply to all aircraft within Australia's jurisdiction. This particular directive pertains to the Mystere-Falcon 200 series aeroplanes, irrespective of their serial numbers, and requires operators to inspect and modify the engine cowl attachments as stipulated in DGAC AD 91-197-018(B). This directive applies to all aircraft registered in Australia, enforcing a compliance timeline that permits a two-month deferral from the revised effective date of 12 December 1991. The regulation responds to reported instances of fatigue cracking in engine cowl attachments, which could potentially result in the loss of small aprons and hinged cowls during flight, thereby ensuring the continued airworthiness of affected aircraft.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, detail the Civil Aviation Safety Authority's (CASA) schedule of airworthiness directives for various aircraft, including the AMD Fan Jet Falcon (Falcon 20/Mystere-Falcon 200) series aeroplanes. AD/AMD 20/24 pertains to engine cowl attachment issues and mandates that all Mystere-Falcon 200 aircraft, regardless of serial number, undergo inspection and modification of their engine cowl attachments (section 12/91). This requirement is to be executed in accordance with the technical specifications outlined in DGAC AD 91-197-018(B). For Australian-registered aircraft, compliance with these directives must align with the requirements specified in the associated Requirement Document, with an effective date of 12 December 1991.
The obligations under this directive are clear and specific. Aircraft operators and owners must ensure that the engine cowl attachments of their Mystere-Falcon 200 aircraft are inspected and modified as per the outlined technical requirements. This involves detailed examination and, if necessary, repair or replacement of the engine cowl attachments to prevent fatigue cracking, which could compromise the structural integrity of the aircraft during flight. Operators must document all actions taken to comply with the directive and maintain records of the inspections and modifications performed.
Failure to comply with these airworthiness directives can result in severe consequences. Section 91.65 of the Civil Aviation Regulations 1998 stipulates that any non-compliance with an airworthiness directive is an offence. The penalties for such breaches can include substantial fines and potential imprisonment for individuals found guilty of contravening the regulations. The specific penalties, as outlined in section 91.66, may vary depending on the severity of the non-compliance, but they are designed to ensure that aircraft maintain the highest safety standards at all times.
In summary, the Civil Aviation Regulations 1998 mandate thorough inspections and modifications of engine cowl attachments on Mystere-Falcon 200 aircraft to prevent potential in-flight failures. Operators are required to adhere to the specified technical requirements and maintain accurate records of compliance. Non-compliance with these directives is a serious offence, with potential criminal penalties for those found guilty. The regulations are clear in their aim to enhance aviation safety by ensuring that all aircraft meet stringent airworthiness standards.
