COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Boeing 767 Series Aeroplanes
AD/B767/46 Vertical Stabiliser 12/90
Applicability: Model 767 line numbers 002 through 299.
Requirement: Action in accordance with Boeing Alert SB767-55A0007.
Note: FAA AD 90-18-05 Amdt 39-6713 refers.
Compliance: Unless previously accomplished, prior to 30 April 1992.
Background: Country of origin AD. To prevent overpressurization of the vertical stabilizer, which could cause structural failure. This could happen if rapid decompression of the fuselage occurred in the stabilizer area.
Overview
The Civil Aviation Regulations 1998 were enacted by the Australian Government to provide a comprehensive framework for ensuring the safety and efficiency of civil aviation within the country. Specifically, Part 39 of these regulations, which deals with Airworthiness Directives, was introduced to address the need for consistent safety standards and requirements across the aviation industry. One such directive, AD/B767/46, pertains to the Boeing 767 Series Aeroplanes and mandates specific actions concerning the vertical stabiliser to prevent overpressurization that could lead to structural failure, particularly in the event of rapid fuselage decompression in the stabiliser area. This directive was issued by the Civil Aviation Safety Authority and references Boeing Alert SB767-55A0007 and FAA AD 90-18-05 Amdt 39-6713, reflecting a collaborative approach to aviation safety. The policy objective of this directive is to ensure the continued airworthiness and safety of Boeing 767 aircraft by addressing potential structural vulnerabilities.
Scope and Application
The Civil Aviation Regulations 1998, under Part 39 - 105, specifically address the airworthiness directives for the Boeing 767 series aeroplanes, with a particular focus on the vertical stabilizer. The regulations apply to all Boeing 767 aircraft with line numbers ranging from 002 to 299. The primary objective of this directive is to mandate actions in compliance with Boeing Alert SB767-55A0007, which is aimed at preventing overpressurisation of the vertical stabiliser that could lead to structural failure, particularly in the event of rapid decompression in the stabilizer area. This directive references the FAA AD 90-18-05 Amendment 39-6713 and requires that any necessary actions be completed prior to 30 April 1992, unless they have already been accomplished. The regulations are intended to ensure the safety and airworthiness of the specified aircraft models within the Australian jurisdiction, thereby extending the regulatory oversight to the specified geographic and operational scope.
Key Provisions
The key operative sections of the Civil Aviation Regulations 1998, specifically PART 39 - 105, which concerns the Civil Aviation Safety Authority's Schedule of Airworthiness Directives for Boeing 767 Series Aeroplanes, are set out in AD/B767/46. This directive applies to Model 767 line numbers 002 through 299. The requirement stated is that action must be taken in accordance with Boeing Alert SB767-55A0007. This is intended to prevent overpressurisation of the vertical stabiliser, which could lead to structural failure due to rapid decompression in the stabiliser area. The directive references FAA AD 90-18-05 Amdt 39-6713 for further information.
The obligations imposed by this Act on the relevant parties include ensuring that all actions mandated by Boeing Alert SB767-55A0007 are carried out on the specified models of Boeing 767 aeroplanes. This involves a thorough inspection and possible modification of the vertical stabiliser to mitigate the risk of overpressurisation and structural failure. Compliance with this directive is critical to maintaining the airworthiness of these aircraft and ensuring passenger safety. The directive requires that any necessary actions be completed unless they have already been accomplished prior to the specified date, 30 April 1992.
Failing to comply with the requirements set out in AD/B767/46 could result in significant civil and criminal consequences. While the specific penalties are not detailed in the excerpt, breaches of airworthiness directives under the Civil Aviation Regulations 1998 can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions may include fines, penalties, and potential grounding of non-compliant aircraft. The severity of the penalties may depend on the extent of the non-compliance and the risk posed to aviation safety. It is crucial for operators of Boeing 767 aeroplanes within the specified range to adhere to these directives to avoid any legal repercussions.
