Overview

The Civil Aviation Regulations 1998 were enacted to regulate the safety standards for civil aviation in Australia, ensuring the protection of the public and the safe operation of aircraft. Part 39 of these regulations, specifically Schedule of Airworthiness Directives, was introduced to address safety concerns and ensure compliance with international standards. This legislative instrument was enacted by the Civil Aviation Safety Authority (CASA) under the authority of the Civil Aviation Act 1988, aiming to maintain and enhance the safety of civil aviation in Australia. The policy objective behind these regulations is to prevent incidents and accidents by setting stringent safety standards and requiring regular inspections and maintenance of aircraft to identify and rectify any unsafe conditions.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, encompasses a detailed schedule of Airworthiness Directives that govern the maintenance and safety standards for various aircraft types, including the Boeing 727 series aeroplanes. This legislation applies to specific models of Boeing 727 aircraft, namely the 727-100, -100C, and -200 series, within a specified line number range, excluding those that have already implemented certain modifications as outlined in Boeing Service Bulletins 727-57-0127 Revision 2 or Revision 3. The directive is issued by a delegate of the Civil Aviation Safety Authority (CASA) and is intended to ensure the airworthiness of the affected aircraft by addressing issues such as fatigue cracking and corrosion that may compromise structural integrity. Compliance with this Airworthiness Directive is mandatory and must be adhered to within the timeframe specified in the requirement document, with the directive taking effect from 15 June 2000. This legislation applies nationally within the Australian jurisdiction, impacting the aviation industry by setting stringent safety standards for the operation and maintenance of the specified aircraft models.

Key Provisions

The Airworthiness Directive (AD) B727/168 pertains to the inspection and maintenance of the wing rib-to-stringer attachment on Boeing 727 Series aeroplanes, specifically models 727-100, -100C, and -200. This directive applies to aircraft with line numbers ranging from 1 through 1214, except for those that have already been modified according to Boeing Service Bulletin (SB) 727-57-0127 Revision 2 or Revision 3. The directive requires these aircraft to be inspected in accordance with the technical requirements outlined in FAA AD 2000-07-12 Amdt 39-11666. The inspections must be completed by 15 June 2000, as detailed in the Requirement document for initial and repetitive inspections, marking the directive's effective date. The obligations imposed by AD B727/168 include ensuring that the specified inspections are conducted properly and in a timely manner. Operators of the affected Boeing 727 Series aircraft must follow the detailed inspection procedures set out in the FAA AD 2000-07-12 Amdt 39-11666. This requirement applies to all relevant aircraft unless they have already been modified according to Boeing SB 727-57-0127 Revision 2 or Revision 3, in which case the directive's requirements are deemed fulfilled. The directive ensures that these inspections are conducted by the specified date to maintain the structural integrity of the aircraft and prevent any degradation of their capabilities. Failure to comply with the AD B727/168 may result in serious safety implications, as it is intended to prevent fatigue cracking and corrosion in the wing rib-to-stringer attachment. The Civil Aviation Safety Authority (CASA) delegate, Bernard Malcolm Hole, issued this directive under subregulation 39.1 (1) of the Civil Aviation Regulations 1998, underscoring the importance of adherence to these safety measures. Non-compliance could lead to significant risks, including potential structural failure, which could endanger the safety of the flight crew, passengers, and others. The directive is legally enforceable, and any breach may result in penalties as prescribed by the Civil Aviation Regulations 1998.
