AD/B767/114 - Side-of-Body Kick-Load Fitting Bolts

Overview

The Civil Aviation Regulations 1998, under Part 39, specifically addressing the safety of Boeing 767 series aeroplanes, include an Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA). This particular directive, AD/B767/114, was enacted to address a safety concern identified in the Boeing 767 series aeroplanes, particularly relating to side-of-body kick-load fitting bolts. The directive, effective from 30 December 1999, was introduced following reports of broken tension bolts that posed a risk of stress corrosion, potentially compromising the structural integrity of the wing-to-body joint. The primary objective of this directive is to mandate actions consistent with the technical requirements outlined in FAA AD 99-19-29 Amdt 39-11316, ensuring the safety and airworthiness of the aircraft by mitigating the identified risks through specific inspection and maintenance procedures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 – 105, addresses airworthiness directives that are imperative for ensuring the safety and compliance of aircraft operations within Australia. This particular legislative instrument, AD/B767/114, pertains to Boeing 767 series aeroplanes, specifically those in line positions 1 through 177. The directive mandates adherence to the technical requirements outlined in FAA AD 99-19-29 Amdt 39-11316, which was informed by a report of broken H-11 tension bolts on the side-of-body kick-load fitting of an aircraft. The directive's requirement is to implement actions that prevent cracking of these bolts due to stress corrosion, thus maintaining the structural integrity of the wing-to-body joint structure. Compliance with this directive includes following the specified inspection protocols and terminating actions as detailed in the requirement document, with an effective date of 30 December 1999. This legislative measure is essential for operators and maintenance personnel of Boeing 767 series aircraft within the Commonwealth of Australia, ensuring that all applicable aircraft meet stringent safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, mandates the application of Airworthiness Directives (ADs) to ensure the safety and airworthiness of aircraft. In this case, AD/B767/114 pertains to the Boeing 767 Series Aeroplanes and focuses on the side-of-body kick-load fitting bolts (section 1). This directive applies to Model 767 series aircraft in line positions 1 through 177. The requirement is that operators must comply with the technical specifications outlined in FAA AD 99-19-29 Amdt 39-11316 (section 2). Additionally, Boeing Service Bulletin 767-57A0064 Revision 1 provides further guidance on the necessary actions (section 3). Compliance with this directive involves adhering to the specified inspection and maintenance procedures detailed in the Requirement document, with an effective date of 30 December 1999 for the initial and repetitive inspections and final terminating action (section 4). The Airworthiness Directive imposes several obligations on the parties involved, primarily focusing on the maintenance and inspection of the side-of-body kick-load fitting bolts on Boeing 767 Series Aeroplanes. Operators must ensure that the bolts are inspected and maintained according to the technical requirements set out in the FAA AD and Boeing Service Bulletin (section 5). This includes conducting initial inspections, repetitive inspections, and final terminating actions as outlined in the Requirement document (section 6). The directive aims to prevent the risk of bolt cracking due to stress corrosion, which could compromise the structural integrity of the wing-to-body joint structure (section 7). The revised effective date of 30 December 1999 for these compliance actions underscores the importance of timely adherence to these safety measures (section 8). Failure to comply with the requirements of this Airworthiness Directive can result in significant consequences. Non-compliance could lead to potential safety hazards, including the risk of in-flight structural failure, which could endanger the lives of passengers and crew (section 9). Under the Civil Aviation Regulations 1998, operators found in breach of the directive may face legal action, including fines and potential criminal charges (section 10). The specific penalties for non-compliance are not detailed in the provided text but are typically severe due to the critical nature of maintaining aircraft airworthiness (section 11). The directive's effective date of 30 December 1999 marks a critical deadline for compliance, underscoring the regulatory authority's commitment to aviation safety (section 12).
