COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 727 Series Aeroplanes
AD/B727/6 Engine Cone Bolt Nut - Inspection and Replacement 10/65
Applicabilty: All models. Document: Boeing SB No. 71-23. Compliance: Forthwith.
Overview
The Civil Aviation Regulations 1998 (Cth) were enacted by the Parliament of Australia and subsequently amended through various legislative instruments to address the need for stringent and consistent aviation safety standards across Australia. A specific amendment, F2006B02762, introduced an Airworthiness Directive (AD) concerning Boeing 727 Series Aeroplanes, aiming to ensure the safety of these aircraft by mandating the inspection and replacement of engine cone bolt nuts. This amendment is part of a broader regulatory framework under the Civil Aviation Act 1988, which seeks to mitigate risks and enhance the overall safety of civil aviation operations in Australia. The policy objective behind such directives is to maintain the highest standards of airworthiness and to protect passengers, crew, and the general public from potential hazards associated with aircraft operations.
Scope and Application
The Civil Aviation Regulations 1998, specifically within Part 39 - 105, govern the maintenance and safety standards of aircraft operations across Australia. This regulatory framework is enforced by the Civil Aviation Safety Authority (CASA) and applies to all entities and individuals involved in the operation, maintenance, and modification of aircraft, with a particular focus on Boeing 727 series aeroplanes. The directive mandates immediate compliance with Airworthiness Directive AD/B727/6 concerning the inspection and replacement of engine cone bolt nuts, as detailed in Boeing Service Bulletin No. 71-23. This directive applies nationally and does not exclude any operators or aircraft within the specified series. The regulations are comprehensive and may be further defined or amended through subordinate instruments issued by CASA, ensuring that safety standards are consistently met and enforced across the industry.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39 - 105, mandate specific safety directives for certain aircraft, including Boeing 727 Series aeroplanes. The regulation focuses on an Airworthiness Directive (AD) related to the engine cone bolt nut, identified as AD/B727/6. This directive (section 10/65) applies universally to all models within the Boeing 727 series, necessitating immediate compliance as indicated in Boeing Service Bulletin No. 71-23. Essentially, it requires that the engine cone bolt nut be inspected and replaced as per the specified guidelines to ensure the continued airworthiness of the aircraft.
The AD imposes clear obligations on aircraft operators and maintenance personnel. Operators must ensure that inspections and any necessary replacements of the engine cone bolt nut are carried out without delay. Maintenance personnel are required to follow the detailed procedures outlined in the Boeing Service Bulletin No. 71-23 to perform these tasks correctly. Compliance must be achieved forthwith, meaning that the actions mandated by the AD must be completed immediately, without any unreasonable delay, to maintain the safety and operational integrity of the aircraft.
Failure to comply with the AD/B727/6 could result in serious consequences. The Civil Aviation Safety Authority (CASA) may take enforcement action against non-compliant aircraft, which could include grounding the aeroplane until the required maintenance is performed. Additionally, operators and maintenance personnel who fail to adhere to the AD could face regulatory penalties. While the specific penalties are not detailed in the regulation itself, they can include fines and other administrative sanctions under the Civil Aviation Act 1988. In severe cases, there may also be criminal penalties if the failure to comply results in safety incidents or accidents.
