AD/B747/9 - Fuel Valve Actuator - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, form a comprehensive legal framework governing civil aviation in the country. The regulations aim to ensure the safety and efficiency of air travel, encompassing various aspects of aircraft operations, airworthiness, and personnel qualifications. One such regulation is Part 39, which includes Airworthiness Directives (ADs) designed to address specific safety issues in aircraft operations. AD/B747/9, for instance, concerns the modification of the fuel valve actuator in Boeing 747 series aeroplanes to mitigate identified risks. This directive was introduced to ensure the continued airworthiness of these aircraft and to address potential safety hazards associated with the fuel valve actuator. The Civil Aviation Safety Authority (CASA) is responsible for issuing these directives, with the overarching policy objective being the enhancement of aviation safety through proactive measures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the Airworthiness Directives for Boeing 747 Series Aeroplanes, focusing on modifications to the fuel valve actuator as outlined in AD/B747/9. This legislative instrument applies universally to all models of Boeing 747 aeroplanes operating within Australian airspace and is enforced by the Civil Aviation Safety Authority. The directive mandates compliance with the technical specifications and requirements laid out in the FAA AD 77-12-07 Amendment 39-2924 document, ensuring that all relevant fuel valve actuators meet the necessary safety standards. The scope of this legislation encompasses the maintenance and operational standards for these aircraft, which are critical for ensuring airworthiness and passenger safety. Subordinate instruments may further extend or detail the application of these regulations, but the primary directive applies to all entities operating Boeing 747 aeroplanes in Australia.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, establishes the Civil Aviation Safety Authority’s (CASA) Schedule of Airworthiness Directives (AD) for various aircraft types. Within this schedule, AD/B747/9 pertains to Boeing 747 series aeroplanes, detailing a requirement for the modification of the fuel valve actuator as outlined in FAA AD 77-12-07 Amendment 39-2924 (Sections 39-105). This AD applies to all models of the Boeing 747 series and mandates specific modifications to ensure the continued airworthiness of these aircraft. Compliance with AD/B747/9 involves several obligations for operators and maintenance personnel. They must ensure that the fuel valve actuator is modified according to the specifications detailed in the FAA AD 77-12-07 Amendment 39-2924. This includes following the requirement document closely to implement the necessary changes and conducting post-modification inspections to verify that the modifications have been correctly executed and that the aircraft now meets the safety standards set forth by CASA (Sections 39-105 and FAA AD 77-12-07 Amdt. 39-2924). Failure to comply with the provisions of AD/B747/9 can result in serious consequences. Under the Civil Aviation Act 1988, non-compliance with an AD can lead to significant penalties. Civil penalties for non-compliance may include fines of up to $207,500 for individuals and higher amounts for corporations, depending on the severity and frequency of the breach (Section 39-105 and Civil Aviation Act 1988). Additionally, continued operation of an aircraft that does not comply with applicable ADs can result in the CASA grounding the aircraft, which can severely disrupt an airline's operations and potentially lead to criminal charges against responsible individuals or entities.
