AD/B727/41 - Outboard Fuel Tank Access Door Bonding - Modification

Overview

The Civil Aviation Regulations 1998, as amended by the Legislative Instrument F2006B02742, address the safety of civil aviation in Australia, particularly focusing on the airworthiness of specific aircraft models. This legislative instrument was introduced to ensure that the Boeing 727 Series Aeroplanes comply with specific safety standards, particularly in relation to the bonding of the outboard fuel tank access door. This was enacted by the Australian Government to mitigate risks associated with fuel tank integrity, which could potentially lead to catastrophic in-flight incidents. The policy objective stated in the text is to mandate compliance with Boeing Service Bulletin No. 28-28, ensuring that the bonding of the outboard fuel tank access door is performed forthwith to maintain the airworthiness of the aircraft. The enactment of this legislative instrument by the Australian Government, through the relevant regulatory authority, demonstrates a commitment to stringent safety standards in civil aviation. The objective is to enhance the safety of air travel by ensuring that all Boeing 727 Series Aeroplanes meet the specified safety directives, thereby protecting passengers, crew, and the general public from potential hazards associated with fuel tank access door integrity.

Scope and Application

The Civil Aviation Safety Authority (CASA) has established an Airworthiness Directive (AD) under the Civil Aviation Regulations 1998, specifically within Part 39, to ensure the safety and airworthiness of Boeing 727 series aeroplanes. This directive, identified as AD/B727/41, mandates modifications to the outboard fuel tank access door bonding. The directive applies to all models of Boeing 727 aeroplanes and requires compliance to be achieved forthwith, as outlined in Boeing Service Bulletin No. 28-28. The AD is applicable within the Commonwealth of Australia, imposing a mandatory requirement on aircraft operators, maintenance organisations, and other relevant entities to adhere to the specified modifications. The directive does not specify any exclusions or thresholds, implying that all Boeing 727 aeroplanes within the jurisdiction must comply with the stipulated modifications. The scope and enforcement of the directive may be extended or refined through subordinate instruments, ensuring the safety standards are consistently applied across the industry.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, Part 39, under the 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives for Boeing 727 Series Aeroplanes, specifically AD/B727/41, focus on the modification of outboard fuel tank access door bonding (paragraph 5/67). This directive applies to all models of the Boeing 727 series. The requirement is for the modification to be implemented immediately, as stipulated in Boeing Service Bulletin No. 28-28, which serves as the compliance document. The obligations imposed by this Act are primarily on the operators of Boeing 727 aircraft. They must ensure that the modifications specified in the directive are carried out without delay. This involves inspecting the outboard fuel tank access doors to confirm they meet the bonding requirements and then performing any necessary modifications to achieve compliance. Operators are mandated to keep detailed records of the inspections and modifications performed, as well as to ensure that all crew members are informed about any changes that could affect their duties. Failure to comply with AD/B727/41 can result in serious consequences. The Act stipulates that non-compliance with an Airworthiness Directive is an offence under the Civil Aviation Act 1988. Operators found in breach of these directives could face substantial penalties. The maximum penalty for an individual is a fine of up to $21,000, while for a corporation, the fine can reach up to $105,000. Additionally, continued operation of a non-compliant aircraft can lead to further civil or criminal liabilities, including potential grounding of the aircraft until the required modifications are satisfactorily completed. These stringent measures underscore the importance of adhering to the specified safety directives to ensure the continued airworthiness of the Boeing 727 series aeroplanes.
