COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 767 Series Aeroplanes
AD/B767/115 Nose Landing Gear Drag Strut 1/2000
Applicability: Model 767-200 and -300 series aircraft, as listed in Boeing Service Bulletin 767- 32A0185, dated September 2 1999.
Requirement: Action in accordance with the technical requirements of FAA AD 99-24-02 Amdt 39- 11426.
Compliance: As specified in the Requirement document with a revised effective date of 31 December 1999.
This Airworthiness Directive becomes effective on 31 December 1999.
Background: The FAA received a report of a fracture of the lower drag strut of the nose landing gear. Investigation revealed the cause as thin wall thickness condition that occurred during the manufacturing process. This directive requires inspections to verify adequate thickness of lower drag struts.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, is a comprehensive set of rules and standards governing civil aviation within the country. Specifically, Part 39 addresses various aspects of aircraft airworthiness and maintenance, including Airworthiness Directives. One such directive, AD/B767/115, pertains to Boeing 767 Series Aeroplanes and was introduced to address a safety issue identified with the nose landing gear drag strut. This directive became effective on 31 December 1999 and mandates actions in accordance with the technical requirements specified by the Federal Aviation Administration (FAA) to ensure the safety of the aircraft. The directive was introduced in response to a reported fracture of the lower drag strut, which was found to result from a thin wall thickness condition during manufacturing. The primary objective of this Airworthiness Directive is to ensure the structural integrity of the nose landing gear by requiring inspections to verify the adequate thickness of the lower drag struts.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the Boeing 767-200 and -300 series aircraft as listed in Boeing Service Bulletin 767-32A0185, dated September 2, 1999. This legislation is integral to ensuring the safety and airworthiness of these aircraft, mandating actions in accordance with the technical requirements of FAA AD 99-24-02 Amdt 39-11426, with compliance required as specified in the requirement document, effective from 31 December 1999. This Airworthiness Directive is designed to address the identified safety issue concerning the potential fracture of the lower drag strut of the nose landing gear, which was found to arise from a thin wall thickness condition during the manufacturing process. The directive mandates inspections to verify the adequate thickness of these struts to ensure continued safe operation of the affected aircraft. The scope of this regulation is limited to the specified Boeing 767 models and does not extend to other aircraft types or components unless explicitly mentioned in subordinate instruments or additional directives.
Key Provisions
The Civil Aviation Regulations 1998, particularly Part 39-105, mandate specific requirements and actions regarding the airworthiness of Boeing 767 series aeroplanes, particularly focusing on the nose landing gear drag strut. Section AD/B767/115 specifically addresses the nose landing gear drag strut issue, indicating that it applies to the Model 767-200 and -300 series aircraft, as detailed in Boeing Service Bulletin 767-32A0185 dated September 2, 1999. The directive requires compliance with the technical requirements outlined in FAA AD 99-24-02 Amendment 39-11426, with a revised effective date of 31 December 1999. This directive was necessitated by a reported fracture of the lower drag strut of the nose landing gear, attributed to a thin wall thickness condition arising from the manufacturing process. Compliance ensures that these aircraft meet the specified airworthiness standards.
The obligations imposed by this legislation on the relevant parties, primarily aircraft manufacturers and operators, are stringent. They must adhere to the technical requirements and procedures outlined in the FAA directive to ensure the structural integrity and safety of the nose landing gear drag struts. This includes conducting thorough inspections to verify the thickness of the struts and taking corrective actions if any deficiencies are found. Operators must ensure that their aircraft comply with these requirements before continuing operations, which may involve scheduling maintenance checks and repairs as necessary.
Failing to comply with these airworthiness directives can result in significant legal and operational consequences. The legislation does not explicitly state the penalties for non-compliance; however, breaches of civil aviation regulations can lead to severe repercussions. Potential penalties may include fines, grounding of the affected aircraft, and other enforcement actions by the Civil Aviation Safety Authority (CASA). These measures are intended to ensure that aircraft remain in a safe and airworthy condition, thereby protecting public safety and maintaining the integrity of the aviation industry. The exact penalties would be determined based on the severity of the non-compliance and the specific provisions of the Civil Aviation Act 1988 and associated regulations.
