Applicability: All models.

 

Requirement: Action in accordance with Boeing SB 727-28-0101. Compliance:  Prior to 30 October 1991.

Background: The incorporation of the Service Bulletin enables aircraft to comply with FAR 25.963(e) which provides for some fuel tank access panels to have a higher resistance to impact to reduce possibility of penetration from engine debris or objects thrown by the aircraft tyres.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Overview

The Civil Aviation Regulations 1998 (Cth) were enacted to ensure the safety and efficiency of civil aviation within Australia. One of the legislative instruments under these regulations, F2006B02642, addresses the specific safety concern of fuel tank access doors in Boeing 727 Series Aeroplanes. This instrument was introduced to address the risk of fuel tank penetration from engine debris or objects thrown by the aircraft tyres, as outlined in Federal Aviation Regulation (FAR) 25.963(e). The policy objective is to enhance the structural integrity of fuel tank access doors to mitigate potential hazards that could compromise the safety of the aircraft. The Civil Aviation Safety Authority, as the enacting body, incorporated Service Bulletin 727-28-0101 to ensure compliance by all operators before 30 October 1991, thereby aligning with international safety standards and protecting the interests of both the aviation industry and the public.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, which pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, applies to all Boeing 727 Series aeroplanes regarding their fuel tank access doors. The directive mandates that these aircraft must comply with the requirements outlined in Boeing Service Bulletin 727-28-0101, ensuring that prior to 30 October 1991, any necessary actions are taken to meet the standards. This legislation is designed to enhance the safety of these aircraft by addressing the potential for fuel tank access panels to be penetrated by engine debris or objects thrown by the aircraft tyres, as specified in Federal Aviation Regulations (FAR) 25.963(e). The regulations have a Commonwealth reach, applying nationally across Australia and are enforced by the Civil Aviation Safety Authority. There are no stated exclusions or exemptions within this directive, and it does not extend or restrict application through subordinate instruments in this instance.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes Airworthiness Directives that govern the maintenance and operation of aircraft in Australia. One such directive, AD/B727/120, pertains to the fuel tank access doors of Boeing 727 Series Aeroplanes (1). This directive applies to all models within the Boeing 727 series and requires compliance with Boeing Service Bulletin 727-28-0101 (2). The main requirement is that the fuel tank access doors must be modified to meet the higher impact resistance standards set forth in Federal Aviation Regulations (FAR) 25.963(e) (3). This action was necessitated to reduce the possibility of penetration from engine debris or objects thrown by the aircraft tyres, thereby enhancing the overall safety of the aircraft. The obligations imposed by AD/B727/120 are clear and direct. Operators and maintainers of Boeing 727 Series Aeroplanes must ensure that the modifications to the fuel tank access doors are carried out in accordance with Boeing SB 727-28-0101 (4). This involves installing new access panels that meet the specified impact resistance requirements. Furthermore, these modifications must be completed before 30 October 1991, as stipulated in the directive (5). Compliance with this directive is not optional; it is a mandatory requirement to ensure that the aircraft remain airworthy and safe for operation. Failure to comply with the provisions of AD/B727/120 can result in significant legal consequences. The Civil Aviation Safety Authority (CASA) is tasked with enforcing these regulations, and non-compliance can lead to enforcement actions against the operators and maintainers. The potential civil penalties for non-compliance can be substantial and may include fines or other sanctions as determined by CASA (6). Additionally, continued operation of an aircraft that does not meet the requirements of this directive could lead to criminal charges, particularly if such non-compliance results in an aviation accident or incident. The maximum penalties for such criminal offences can include imprisonment and/or fines, as outlined under relevant Australian legislation. Therefore, it is imperative that all stakeholders adhere strictly to the directive to avoid these serious consequences.
