AD/B727/78 Amdt 1 - Engine Fuel Feed Forward Shroud Hose Assemblies - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, establish a comprehensive regulatory framework for civil aviation safety, including the issuance of airworthiness directives to address specific safety concerns. One such directive, AD/B727/78 Amendment 1, pertains to the inspection and modification of engine fuel feed forward shroud hose assemblies in Boeing 727 Series aeroplanes. This directive was introduced to address the problem of braid corrosion in hoses constructed with carbon steel braid, which could compromise the integrity of the aircraft's fuel system. The policy objective is to ensure the ongoing airworthiness of the aircraft by mitigating the risks associated with such corrosion. The regulatory authority responsible for enforcing these directives is the Civil Aviation Safety Authority. The directive amends the original requirement by incorporating the latest revision of FAA AD 77-03-02, which eliminates the need for repeat inspections following the installation of corrosion-resistant braided hoses. This update streamlines compliance procedures and enhances safety by ensuring that any issues with the hose assemblies are addressed promptly and effectively.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's schedule of airworthiness directives, focusing on the Boeing 727 Series Aeroplanes. This particular directive, AD/B727/78 Amendment 1, concerns engine fuel feed forward shroud hose assemblies and mandates their inspection and modification due to identified issues with braid corrosion in hoses constructed with carbon steel braid. The directive applies to all models specified in Boeing Service Bulletin No. 727-28-51 Revision 2, which aligns with Federal Aviation Administration Advisory Directive 77-03-02 Amendment 39-4572. The regulation requires compliance with the detailed procedures outlined in the referenced Boeing service bulletin or FAA advisory directive. Notably, the amendment updates the directive to reflect the latest revision, eliminating the necessity for repeated inspections after the installation of corrosion-resistant braided hoses, thereby streamlining the compliance process. The scope of the directive is geographically and jurisdictionally aligned with the Commonwealth of Australia, and it applies uniformly across all relevant entities operating within the Australian aviation sector.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contain various Airworthiness Directives (AD) that govern the maintenance and operation of aircraft in Australia. One such AD is AD/B727/78 Amendment 1, which pertains to Boeing 727 series aeroplanes. This AD focuses on the inspection and modification of engine fuel feed forward shroud hose assemblies, as detailed in Boeing Service Bulletin No. 727-28-51, Revision 2, or FAA AD 77-03-02, Amendment 39-4572. The directive requires compliance with the latest revision of these documents, ensuring that all inspections and modifications are carried out according to the manufacturer's specifications. Under this AD, the applicable aircraft models must undergo an inspection for braid corrosion in the engine fuel feed forward shroud hose assemblies. Braid corrosion in hoses constructed with carbon steel braid is a significant concern, and the AD mandates that any discovered corrosion must be addressed through appropriate modification procedures. This involves following the detailed instructions provided in the specified Boeing Service Bulletin or FAA AD, ensuring that the inspections and modifications are performed correctly to maintain the airworthiness of the aircraft. The AD imposes several obligations on the parties and entities governed by these regulations. Operators and maintenance providers must ensure that all inspections and modifications are conducted in accordance with the specified documents, Boeing SB No. 727-28-51, Rev. 2, or FAA AD 77-03-02, Amdt. 39-4572. This includes timely and thorough inspections of the engine fuel feed forward shroud hose assemblies and the implementation of necessary modifications if braid corrosion is found. Failure to comply with these requirements can result in serious safety risks, and it is imperative that all parties adhere to the AD to ensure the continued safety of the aircraft. Non-compliance with the provisions outlined in the AD can lead to significant legal and safety consequences. While the Civil Aviation Regulations 1998 do not explicitly detail the specific offences, penalties, or civil/criminal consequences for breach in this context, general aviation regulations in Australia provide for substantial penalties for non-compliance with airworthiness directives. Operators and maintenance providers found in breach of these regulations may face fines, enforcement actions, and potential grounding of the aircraft. Additionally, such breaches can result in severe safety implications, potentially leading to criminal charges if negligence or intentional disregard for safety protocols is established. Therefore, adherence to the AD is critical to avoid these serious repercussions.
