SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 747 Series Aeroplanes
AD/B747/154
Amdt 1
Nacelle Strut and Wing Structure - Rolls Royce RB211 Series Engine
2/96
Applicability: Model 747 series aircraft with line positions 292 through 1033, equipped with Rolls Royce RB211 series engine.
Requirement: Action in accordance with the technical requirements of FAA AD 95-13-05 Amdt 39- 9285.
Note: Boeing Alert Service Bulletin 747-54A2157 Revision 1 refers.
Compliance: As specified in the Requirement Document.
The Compliance of the initial issue of this Directive remains unchanged. This Amendment is effective from 1 February 1996.
Background: The FAA requires the incorporation of a modification of the strut and wing structure that has been developed by the manufacturer to improve the damage tolerance capability and durability of the strut-to-wing attachments, and reduce reliance on inspections of those attachments. Amendment 1 is issued to introduce a revision of the manufacturer's service bulletin which is related to this Directive.
Overview
The Civil Aviation Regulations 1998, specifically Part 39, were enacted to establish the framework for maintaining airworthiness in civil aviation, ensuring safety and compliance with international standards. One such regulation is AD/B747/154 Amendment 1, introduced in 1996 by the Civil Aviation Safety Authority (CASA) to address issues related to the nacelle strut and wing structure of Boeing 747 series aeroplanes equipped with Rolls Royce RB211 series engines. This amendment was necessitated by the need to incorporate modifications developed by the manufacturer to enhance the damage tolerance capability and durability of the strut-to-wing attachments, as mandated by the Federal Aviation Administration (FAA). The objective of this amendment is to ensure that the modifications improve safety and reduce the reliance on frequent inspections of these critical components, thereby maintaining the airworthiness of the aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to Boeing 747 series aeroplanes with line positions 292 through 1033 that are equipped with Rolls Royce RB211 series engines. This legislation pertains to the safety standards and maintenance directives for aircraft within its scope, ensuring compliance with the technical requirements set by the Federal Aviation Administration (FAA) as detailed in FAA AD 95-13-05 Amdt 39-9285. Boeing Alert Service Bulletin 747-54A2157 Revision 1 is also referenced for further guidance. The regulation mandates actions in accordance with the specified technical requirements and sets forth the compliance standards that must be adhered to by the operators of these aircraft. The regulation was amended on 1 February 1996 to incorporate a revision of the manufacturer's service bulletin related to this directive. The amendment aims to enhance the damage tolerance capability and durability of the strut-to-wing attachments and reduce the need for frequent inspections of these components. This legislative instrument is applicable within the Commonwealth of Australia and ensures that the specified modifications and compliance standards are uniformly enforced across all relevant jurisdictions.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 105, outlines the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives (ADs) for the Boeing 747 series aircraft. Among these, AD/B747/154 Amendment 1 focuses on the nacelle strut and wing structure for aircraft equipped with Rolls Royce RB211 series engines. This directive applies to Boeing 747 series aircraft with line positions between 292 and 1033, all of which are required to comply with the technical requirements outlined in FAA AD 95-13-05 Amendment 39-9285. Boeing Alert Service Bulletin 747-54A2157 Revision 1 is referenced as an additional resource for compliance.
The directive mandates compliance with the technical requirements specified in the Requirement Document, ensuring that modifications to the strut and wing structure are implemented as directed. These modifications are intended to enhance the damage tolerance capability and durability of the strut-to-wing attachments, thereby reducing the need for frequent inspections. The compliance requirement for the initial issue of this Directive remains unchanged, and Amendment 1 became effective from 1 February 1996.
Operators of Boeing 747 series aircraft within the specified line positions must ensure that the modifications are carried out in accordance with the FAA’s requirements. This includes adherence to the detailed instructions provided in the Requirement Document and any referenced service bulletins. Non-compliance with these directives can lead to significant safety risks, as the modifications are critical for maintaining the structural integrity of the aircraft.
Failure to comply with the provisions of AD/B747/154 Amendment 1 can result in severe consequences. The regulations do not explicitly state civil or criminal penalties for non-compliance in the provided text, but non-compliance could potentially lead to aircraft being grounded or deemed unairworthy by CASA. This could result in hefty fines, operational restrictions, or even criminal charges if the non-compliance is deemed to have caused an incident or endangered safety. The seriousness of the consequences underscores the importance of adhering to the ADs as mandated by CASA.
