COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
AMD Falcon 50 and 900 Series Aeroplanes
AD/AMD 50/3
Amdt 1
MLG Door Emergency Release Lever and Pin 8/89
Applicability: All models 50 and 900 aircraft.
Requirement: 1. Unless Requirement 2 has been accomplished, carry out a manual opening of the main landing gear doors in accordance with the instructions of the manufacturer Maintenance Manual; Work Card 480.0 Para. 3 for the model 50 and Maintenance Procedure 32-120 for the model 900. Check for broken MLG door emergency release pins.
2. Action in accordance with Service Bulletins: F50-208 for the Mystere-Falcon 50; and F900-52 for the Mystere-Falcon 900.
Note 1: Compliance with Requirement 2 constitutes terminating action for this AD. Note 2: DGAC AD 88-140-006(B)R2 and DGAC AD 89-041-007(B) refer.
Compliance: 1. Prior to the accumulation of 1000 landings.
2. Prior to the accumulation of 2000 landings.
Background: This Airworthiness Directive is prompted by reports of the MLG door emergency release pin breaking due to fatigue failure. An inspection plus a modification that replaces the release lever and splined pin, has been introduced by the manufacturer to prevent the possible inability to carry out an emergency extension.
This Amendment is raised to correct a typographical error.
Overview
The Civil Aviation Regulations 1998, amended by the Legislative instrument F2006B02396, addresses safety concerns related to the Falcon 50 and 900 series aeroplanes. Specifically, this legislative instrument targets the issue of the main landing gear (MLG) door emergency release lever and pin experiencing fatigue failure, which could compromise emergency procedures. Enacted by the Commonwealth of Australia, this regulation aims to ensure the continued airworthiness and safety of these aircraft by mandating inspections and necessary modifications. Compliance is required prior to the aircraft accumulating 1000 and 2000 landings respectively, ensuring that the emergency release system functions correctly and reliably. The directive references service bulletins and previous airworthiness directives from the Direction Générale de l'Aviation Civile (DGAC) to provide a comprehensive approach to resolving this safety issue.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, which pertains to the Civil Aviation Safety Authority Schedule of Airworthiness Directives, mandates compliance for all Falcon 50 and 900 series aeroplanes. This legislation ensures that the main landing gear (MLG) door emergency release lever and pin are inspected and, if necessary, replaced to prevent potential inoperability in emergency situations. The requirements outlined necessitate a manual inspection and possible replacement of the emergency release pins, with detailed instructions provided in the manufacturer's Maintenance Manual. The regulations specify that these actions must be completed prior to the aircraft accumulating 1000 and 2000 landings, respectively, and compliance is further detailed in relevant Service Bulletins. The application of these directives is extensive, covering all models within the specified series, and they apply across the entire Commonwealth of Australia, enforced by the Civil Aviation Safety Authority. There are no stated exclusions or exemptions within the provided text, though the regulations might be subject to further clarification or modification through subordinate instruments.
Key Provisions
The Civil Aviation Regulations 1998, specifically in Part 39 - 105, address the airworthiness directives for the Falcon 50 and 900 series aeroplanes, particularly focusing on the MLG Door Emergency Release Lever and Pin (AD/AMD 50/3 Amendment 1). These regulations mandate certain actions to ensure the safety of the aircraft operations. Under section 1, operators must manually open the main landing gear (MLG) doors and check for broken MLG door emergency release pins as per the manufacturer's instructions detailed in the Maintenance Manual; Work Card 480.0 Para. 3 for the model 50 and Maintenance Procedure 32-120 for the model 900. Additionally, they must follow the specific service bulletins F50-208 for the Mystere-Falcon 50 and F900-52 for the Mystere-Falcon 900. Compliance with these service bulletins concludes the required actions for this Airworthiness Directive.
The obligations under these regulations are clear and specific. Operators of the Falcon 50 and 900 series aircraft must ensure that the manual opening of the MLG doors is carried out before the aircraft accumulates 1000 landings, and the service bulletin actions must be completed before the aircraft accumulates 2000 landings. These requirements are intended to prevent potential failures in the emergency release mechanism, which could compromise the safety of the aircraft in an emergency situation. It is important that these directives are adhered to strictly to maintain the airworthiness of the aircraft.
Failure to comply with these airworthiness directives can have significant legal and safety implications. While the specific penalties for non-compliance are not detailed in the text provided, generally, under the Civil Aviation Act 1988, violations of airworthiness directives can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions can include fines, grounding of the aircraft, or even more severe penalties if non-compliance is found to have contributed to an aviation incident or accident. It is imperative for operators to ensure full compliance to avoid these potential consequences.
