AD/AMD 10/11 - Emergency Landing Gear Control Actuating Spring - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, establish and enforce the necessary safety standards for civil aviation within Australia. These regulations are crucial for ensuring the airworthiness of aircraft and the safety of passengers and crew. One specific aspect of these regulations is the issuance of Airworthiness Directives (ADs) that address identified safety issues or discrepancies in specific aircraft models. The AD/AMD 10/11 for the Falcon 10 Series Aeroplanes is one such directive aimed at rectifying an issue with the emergency landing gear control actuating spring, which affects certain serial numbers within the series. This amendment is a response to a recognised safety concern that needed immediate attention to prevent potential failures during critical phases of flight. The policy objective of this directive is to ensure that the affected aircraft models meet the necessary safety standards by implementing the specified modifications before a given compliance date, thereby enhancing the overall safety of civil aviation in Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105, pertains to the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, with a focus on the Falcon 10 Series Aeroplanes. This legislation applies to all models within the Falcon 10 Series with serial numbers ranging from 1 to 134, with notable exceptions for serial numbers 126, 127, 129, 130, and 133. The scope of the Act is to mandate modifications to the emergency landing gear control actuating spring, as outlined in document AMD SB BA F10-0173 (F10-32-023), to ensure compliance with safety standards. The directive requires that these modifications be completed before 30 April 1979. This regulation holds jurisdictional reach throughout Australia under the Commonwealth, impacting aircraft owners, operators, and maintenance providers who must adhere to these specifications to maintain the airworthiness of their Falcon 10 Series aircraft.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, details the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives, including the AD/AMD 10/11 concerning Falcon 10 Series Aeroplanes. This directive addresses the Emergency Landing Gear Control Actuating Spring and applies to all Falcon 10 models with serial numbers ranging from 1 to 134, with specific exceptions for serial numbers 126, 127, 129, 130, and 133. Compliance with these directives is mandated by the regulations and is critical for ensuring the safety and airworthiness of the aircraft. The directive references the document AMD SB BA F10-0173 (F10-32-023) which provides detailed instructions and specifications for the required modifications. Under the Civil Aviation Regulations 1998, the primary obligation for the operators and owners of Falcon 10 Series Aeroplanes is to ensure that the modifications outlined in the AD/AMD 10/11 are completed before 30 April 1979. These modifications are essential to address potential safety issues related to the emergency landing gear control actuating spring. Compliance involves conducting a thorough inspection of the aircraft to confirm that the specified serial numbers are covered by the directive and that the necessary modifications have been implemented as per the technical bulletin AMD SB BA F10-0173. Failure to comply with the AD/AMD 10/11 may result in severe legal consequences. The Civil Aviation Regulations 1998 outline that non-compliance with airworthiness directives can lead to substantial penalties. While the specific penalties are not detailed in the provided excerpt, it is well established under the Civil Aviation Act 1988 that violations of CASA directives can result in fines and other civil or criminal penalties. The severity of the penalty often correlates with the level of risk posed by the non-compliance, with potential criminal charges for serious or repeated violations. In summary, the AD/AMD 10/11 under the Civil Aviation Regulations 1998 mandates specific modifications to the emergency landing gear control actuating spring for Falcon 10 Series Aeroplanes with certain serial numbers, excluding a few specific models. Operators and owners must ensure these modifications are completed by the specified deadline. Non-compliance can lead to significant legal repercussions, including fines and potentially criminal charges, underscoring the importance of adhering to these safety directives to maintain the airworthiness and safety of the aircraft.
