COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Background: The FAA has advised that the results of an engineering review of the main deck cargo door control box wiring diagram revealed the potential for failures of the control box to occur, which could result in the inadvertent inflight opening of the main deck cargo door. Actions required by this Directive are intended to prevent such failures occurring.
Overview
The Civil Aviation Regulations 1998, as amended, is a key piece of legislation in Australia governing aviation safety. In particular, Part 39 - 105 under the Civil Aviation Safety Authority schedule of airworthiness directives aims to ensure the safety of aircraft operations. This legislative instrument, F2006B02673, addresses specific safety concerns related to Boeing 727 Series aeroplanes, particularly those that have undergone modifications in line with FAA Supplemental Type Certificate SA1797SO. The primary objective of this directive, issued on 23 October 1996, is to mitigate the risk of inflight main deck cargo door failure by mandating rigorous inspections and necessary repairs or modifications to the control box wiring. Compliance with these requirements is crucial to ensure the continued airworthiness and safety of affected aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, outlines Airworthiness Directives concerning Boeing 727 series aeroplanes, addressing safety concerns related to the main deck cargo door. This particular directive, AD/B727/150, applies to Model 727-100 and -200 series aeroplanes modified in accordance with FAA Supplemental Type Certificate SA1797SO. The directive mandates a comprehensive inspection of the main deck cargo door control box, focusing on identifying and rectifying issues such as damaged electrical wires, loose connections, and improperly installed or restrained wiring. Compliance with the directive is mandatory, with specific timelines for performing inspections and making necessary modifications to prevent potential in-flight failures of the cargo door control box. This directive ensures that the aircraft maintain the required safety standards, thereby protecting passengers and crew during flight operations.
Key Provisions
The Civil Aviation Regulations 1998, Part 39, Section 105, specifies an Airworthiness Directive (AD) for Boeing 727 Series Aeroplanes, particularly focusing on the main deck cargo door. The directive AD/B727/150 (Section 1) applies to Model 727-100 and -200 series aeroplanes that have been modified according to FAA Supplemental Type Certificate SA1797SO. The main requirements of this directive (Section 2) include a visual inspection of the main deck cargo door control box for specific discrepancies such as damaged electrical wires, loose connections, or damaged protective grommets. If any discrepancies are found, they must be rectified (Section 2(a)-(e)). Additionally, it mandates that the electrical wires or wire bundles be properly installed and restrained according to FAA Advisory Circular 43.13-1A Change 3 or Boeing Wiring Diagram Manual D6-54446 Revision 21 (Section 3). The directive also requires modifications to the wiring and components of the main deck cargo door control box in line with Aeronautical Engineers Inc Service Bulletin Report No R-AEID1 Revision A (Section 4). Compliance with these requirements must be met by specific dates: the initial inspection by 27 October 1996, further flight after inspection and rectification by the same date, and the wiring modifications by 1 January 1997 (Section 5). This Airworthiness Directive became effective on 23 October 1996.
The obligations imposed by this Airworthiness Directive are clear and specific, requiring operators of Boeing 727-100 and -200 series aeroplanes to conduct a thorough visual inspection of the main deck cargo door control box for potential damage or defects. If discrepancies are identified, these must be corrected immediately. Furthermore, operators must ensure that electrical wiring and bundles are correctly installed and secured according to the specified FAA or Boeing documentation. This directive also necessitates modifications to the control box wiring and components, as outlined in the Aeronautical Engineers Inc Service Bulletin. Operators must adhere to these requirements to maintain the airworthiness of their aircraft and ensure passenger safety. Compliance with these provisions is mandatory and failure to do so can result in significant legal and safety implications.
The Civil Aviation Regulations 1998 impose significant consequences for non-compliance with the Airworthiness Directive AD/B727/150. Although the specific penalties are not detailed in the text, non-compliance with Civil Aviation Regulations can result in severe civil and criminal penalties. These may include fines, suspension or revocation of air operator certificates, and potential criminal charges for those responsible for oversight failures. The seriousness of these penalties underscores the importance of adhering to the regulatory requirements. Failure to meet the stipulated deadlines or neglect the mandated inspections and modifications can lead to substantial repercussions, including grounding of the affected aircraft, which could disrupt operations and endanger safety. Therefore, operators must ensure strict compliance with the directive to avoid any legal or safety repercussions.
