AD/B747/10 Amdt 1 - Pressurisation Outflow Valves - Inspection

Overview

The Civil Aviation Regulations 1998, as amended, include specific regulations governing the airworthiness of aircraft, particularly in the form of Airworthiness Directives (ADs). One such directive, AD/B747/10 Amendment 1, was introduced to address the need for inspecting pressurisation outflow valves in Boeing 747 series aeroplanes that do not incorporate Hamilton Standard Service Bulletin No. 21-114, Revision 1. This directive was enacted by the Civil Aviation Safety Authority (CASA), which is the body responsible for regulating civil aviation safety in Australia. The underlying policy objective is to ensure that all civil aircraft meet the required safety standards, thereby safeguarding the public and maintaining the integrity of the aviation industry. The directive aims to mitigate potential risks associated with the pressurisation system, ensuring that any faults or deficiencies are identified and rectified to maintain the overall safety of the aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, establish the scope and application of the Airworthiness Directives concerning Boeing 747 series aeroplanes, as amended by AD/B747/10 Amendment 1. This legislation applies to all Boeing 747 models except those incorporating Hamilton Standard Service Bulletin No. 21-114, Revision 1. The regulation mandates that these aircraft undergo inspections of the pressurisation outflow valves as outlined in the Federal Aviation Administration AD 78-08-04, Amendment 39-3187, which corresponds to Boeing Service Bulletin No. 747-21-2139, Revision 1. Compliance with these directives is imperative and must adhere to the requirements detailed in the relevant documentation. The jurisdictional reach of this regulation is national, applying across the Commonwealth of Australia and overseen by the Civil Aviation Safety Authority. There are no stated exclusions or exemptions within the text provided, and any further extensions or restrictions of application would be detailed in subordinate instruments or additional regulatory documents.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, specifically Part 39 - 105, establish the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives. One such directive, AD/B747/10 Amendment 1, pertains to the pressurisation outflow valves of Boeing 747 series aeroplanes, except for those models incorporating Hamilton Standard SB No. 21-114, Revision 1 (section 11/78). Compliance with this directive is mandated through the referenced document FAA AD 78-08-04, Amendment 39-3187, which corresponds to Boeing Service Bulletin 747-21-2139, Revision 1. This Act imposes specific obligations on the parties or entities it governs. Primarily, it requires operators of Boeing 747 aeroplanes to adhere to the inspection and maintenance requirements outlined in the referenced FAA AD and Boeing SB. Operators must ensure that the pressurisation outflow valves are inspected and maintained according to the detailed instructions in these documents. The directive mandates a thorough and systematic approach to ensuring that the aeroplanes meet the safety standards set by CASA. Breach of the requirements set out in the AD/B747/10 Amendment 1 can result in severe consequences. Civil penalties may be imposed for non-compliance, and operators found to be in breach may face sanctions that include fines or other financial penalties. Additionally, continued operation of an aeroplane that does not meet the airworthiness standards set by CASA can lead to more severe civil or criminal consequences, including potential prosecution under aviation safety laws. The specific penalties are not detailed in the text, but they could include substantial fines and imprisonment for individuals, depending on the severity of the breach and the associated risk to aviation safety.
