Overview

The Civil Aviation Regulations 1998, under Part 39 - 105, introduced by the Parliament of the Commonwealth of Australia, address the need for specific airworthiness directives to ensure the safety of civil aviation. One such directive, AD/B747/45, was enacted to tackle the issue of aft pressure bulkhead damage in Boeing 747 series aeroplanes, as reported by the manufacturer. This directive aims to ensure compliance with the technical requirements set forth by the Federal Aviation Administration (FAA) to prevent unairworthy conditions that could arise from such damage. The policy objective is to maintain the highest safety standards in civil aviation, ensuring that all aircraft remain airworthy and safe for operation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all Boeing 747 series aeroplanes, mandating compliance with the technical requirements of FAA AD 85-22-12 to address issues of aft pressure bulkhead damage. This legislation is applicable to all models of Boeing 747 aeroplanes and requires corrective action to be taken in accordance with the stated directive to ensure airworthiness. The geographic and jurisdictional reach of this regulation extends across the Commonwealth of Australia, overseen by the Civil Aviation Safety Authority (CASA). The regulation imposes no explicit exclusions or exemptions, ensuring that all Boeing 747 series aeroplanes operating within Australian airspace must adhere to the specified requirements. The Act may be extended or restricted through subordinate instruments, which could provide further detailed operational guidance or modifications to the directives as necessary.

Key Provisions

The Civil Aviation Regulations 1998, specifically under PART 39 - 105 (paragraphs 39.105(1) to 39.105(5)), provide detailed requirements for airworthiness directives concerning various types of aircraft, including the Boeing 747 series aeroplanes. One such directive is AD/B747/45, which addresses aft pressure bulkhead damage. According to the regulation, the directive applies to all models of Boeing 747 aeroplanes and mandates compliance with the technical requirements outlined in FAA AD 85-22-12. The directive requires action to be taken to address reported issues of aft bulkhead damage and to ensure that any repairs made prior to 20 December 1985 meet the specified airworthiness criteria. The obligations imposed by these regulations are clear and direct. Operators of Boeing 747 aeroplanes must ensure that any aft pressure bulkhead damage is rectified in accordance with the FAA's technical requirements. This involves conducting thorough inspections and, if necessary, making repairs to ensure that the aircraft remains airworthy. The regulations require operators to maintain comprehensive records of all inspections and repairs carried out on the aft pressure bulkhead. These records must be readily available for inspection by the Civil Aviation Safety Authority (CASA) upon request. Failure to comply with the airworthiness directive can lead to serious consequences. Under the Civil Aviation Act 1988, non-compliance with airworthiness directives can result in significant penalties. For individuals, the maximum penalty is a fine of up to $10,000 or imprisonment for up to six months, or both. For corporations, the penalties can be substantially higher, with fines reaching up to $50,000. In addition to these penalties, non-compliance can also result in the grounding of the aircraft, which can have severe operational and financial implications for the operator. CASA has the authority to issue compliance orders and can take enforcement action against operators who fail to adhere to the airworthiness directives.
