AD/INST/31 - Airborne Vacuum Pumps - Removal from Service

Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, aim to ensure the safety and efficiency of civil aviation in Australia. Specifically, Part 39 addresses airworthiness directives, which are critical in maintaining the safety standards of aircraft. The Act was introduced to address the gap in ensuring that aircraft components meet safety requirements, thereby enhancing overall aviation safety. One such directive, AD/INST/31, pertains to the removal from service of specific airborne vacuum pumps due to potential manufacturing defects that could compromise their operational integrity. This legislative instrument, issued by the Civil Aviation Safety Authority, seeks to mitigate risks associated with the use of these pumps in aircraft, ensuring compliance with safety standards. The policy objective is to enhance the reliability and safety of aircraft components by enforcing the timely replacement of defective parts.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 107, pertain to the directives issued by the Civil Aviation Safety Authority (CASA) concerning airworthiness and operational safety of aircraft. The Act applies to all aircraft operators, maintenance organisations, and aircraft engineers within the Commonwealth of Australia, mandating compliance with the Airworthiness Directives. These directives are particularly focused on the removal from service of certain airborne vacuum pumps identified by specific part numbers and serial numbers to ensure safety and operational integrity. The directive excludes pumps installed before 1 September 1985 and reworked pumps which are marked with a white date code near the discharge port. The requirement is to replace any specified dry air pumps in service with those that have been reworked as applicable, ensuring compliance before the issue of the next Maintenance Release after 31 March 1986. This mandate extends its reach through subordinate instruments, ensuring thorough enforcement and compliance with safety standards.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 107, includes an Airworthiness Directive (AD) concerning Airborne Vacuum Pumps, identified as AD/INST/31. This directive (Section 3/86) mandates the removal from service of certain Airborne Vacuum Pumps that were not available for installation before 1 September 1985. Specifically, it lists various models and serial numbers of Dry Air Pumps and Auxiliary Dry Air Pumps that are subject to this requirement. The directive stipulates that these pumps must be replaced to ensure compliance with safety standards, particularly noting that new pumps installed prior to 1 September 1985 are exempt from this mandate. The AD imposes clear obligations on the operators and maintainers of aircraft equipped with the specified pumps. They must ensure that any listed Dry Air Pumps or Auxiliary Dry Air Pumps in service are replaced with versions that have been reworked by Airborne, as indicated by a white date code stamped on the pump housing near the discharge port. This requirement is non-negotiable and must be completed before the issue of the next Maintenance Release following 31 March 1986. Failure to comply with this directive could potentially compromise the airworthiness of the aircraft, leading to serious safety risks. Non-compliance with the provisions outlined in this Airworthiness Directive can result in severe consequences. The Civil Aviation Safety Authority (CASA) may impose penalties, which could include fines or other administrative actions against the aircraft operators or maintenance entities. While specific maximum penalties are not detailed within this directive, it is clear that the stakes are high, given the critical nature of the affected components. Ignoring or failing to implement the required changes could lead to aircraft being grounded or other enforcement actions being taken to ensure compliance and maintain safety standards.
