Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve to govern the safety and operational standards of civil aviation within the country. One pertinent aspect of these regulations is the detailed scheduling of Airworthiness Directives (ADs) to ensure that aircraft maintain their airworthiness standards over time. The AD/HS 125/53 Amendment 2 specifically addresses the inspection requirements for flap nose ribs on British Aerospace BAe 125 Series aeroplanes. This amendment, introduced in 1984, was designed to address potential safety issues by mandating specific inspections on certain models of the BAe 125 aircraft, thereby enhancing overall aviation safety. The policy objective behind these regulations is to maintain high standards of airworthiness, ensuring the safety of passengers and crew, and preventing incidents related to aircraft structural integrity.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, encompasses a broad range of aviation safety directives, with the present focus on the British Aerospace BAe 125 Series Aeroplanes. This regulation applies to all models of the BAe 125 series that do not incorporate the mod 252772 (revised flap hinge arrangement), including certain specified serial numbers such as NA0311, NA0313, NA0323, NA0325, NA0326, NA0339, and aircraft 7163. The directive mandates a specific inspection of flap nose ribs as detailed in the British Aerospace 125 Series Service Bulletin SB 57-58 Revision 4 dated 10 March 1984, with the latest revisions incorporated into the compliance requirements. The directive extends its applicability to all relevant aircraft registered within the Commonwealth of Australia, overseen by the Civil Aviation Safety Authority (CASA). While this particular directive does not specify exclusions or exemptions, it is essential to comply with the latest revisions of the requirement document to ensure adherence to safety standards. The application of this directive is integral to maintaining the airworthiness of the specified aircraft models under the regulatory framework of Australian civil aviation.
Key Provisions
The Civil Aviation Regulations 1998, specifically under Part 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives, address the maintenance and safety requirements for British Aerospace BAe 125 Series Aeroplanes through AD/HS 125/53 Amendment 2. This amendment pertains to flap nose ribs inspection and is applicable to all models of BAe 125 Series Aeroplanes not incorporating modification 252772, which features a revised flap hinge arrangement. The directive covers aircraft models up to and including 700A and 700B, with specific serial numbers listed such as NA0311, NA0313, NA0323, NA0325, NA0326, NA0339, and 7163. Compliance with this directive must adhere to the British Aerospace 125 Series Service Bulletin 57-58 Revision 4 dated 10 March 1984.
Entities and individuals governed by these regulations must ensure that the specified aircraft undergo the required inspection of flap nose ribs as detailed in the referenced service bulletin. The inspections must be conducted in accordance with the latest revision of the requirement document, which includes the inspection of aircraft previously omitted from the list, specifically NA0311, NA0313, NA0323, NA0325, NA0326, and NA0339. This directive mandates that these inspections are not only performed but also documented accurately to ensure compliance and maintain airworthiness.
Failure to comply with the provisions of AD/HS 125/53 Amendment 2 could result in serious safety implications and legal consequences. The Civil Aviation Safety Authority (CASA) can impose penalties for non-compliance, which may include fines and other administrative actions. The severity of the penalty depends on the nature and extent of the non-compliance, but it can be significant given the critical nature of ensuring airworthiness in aviation. It is imperative for operators and maintainers of BAe 125 Series Aeroplanes to adhere strictly to these directives to avoid any potential breaches and their associated consequences.
