AD/P68/33 Amdt 1 - Engine and Propeller Control Cables

Overview

The Civil Aviation Regulations 1998, as amended, represent a comprehensive framework governing civil aviation operations within Australia, and are enforced by the Civil Aviation Safety Authority (CASA). Among the various parts of these regulations, Part 39 specifically pertains to airworthiness directives, which are mandatory rules designed to address safety issues in aircraft operation. One such directive, AD/P68/33 Amendment 1, pertains to the Partenavia P68 series aeroplanes, specifically targeting issues with engine and propeller control cables. Enacted to address the identified problem of cable failures, which could potentially compromise flight safety, this directive was introduced to ensure the ongoing airworthiness of the affected aircraft models. The objective is to mandate regular inspections and necessary replacements of the specified cables to prevent in-flight failures, thereby enhancing the safety standards of these aircraft within the Australian civil aviation sector. The directive is applicable to Partenavia P68 series aircraft up to and including serial number 394, with the exception of serial number 391. The requirement involves inspecting the engine and propeller control cables in accordance with Partenavia Mandatory Service Bulletin 81 Revision 1, and replacing them if necessary. Compliance with this directive necessitates inspections within 25 hours of time in service after 11 January 1995 and subsequently at intervals not exceeding 25 hours until the replacement is carried out. This requirement was mandated prior to 11 January 1996. The introduction of Amendment 1 reflects the need for a more stringent inspection schedule in response to a reported failure of a specific propeller control cable, thereby underscoring the commitment to maintaining the highest safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to all Partenavia P68 series aeroplanes up to and including serial number 394, with the exception of serial number 391. This legislation is instrumental in ensuring the airworthiness of these aircraft by mandating specific inspection and replacement procedures for engine and propeller control cables. The regulations are applicable to the Commonwealth of Australia and are enforced by the Civil Aviation Safety Authority. The stipulated requirement necessitates inspections in accordance with Partenavia Mandatory Service Bulletin 81 Revision 1, and the replacement of cables must be executed within specific timeframes: inspections are to be carried out within 25 hours of time in service after 11 January 1995 and at intervals not exceeding 25 hours until the cables are replaced. All replacements must be completed before 11 January 1996. These regulations extend their application through subordinate instruments, ensuring compliance with the mandated safety directives.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, address the safety directives for specific aircraft models. One such directive, AD/P68/33 Amendment 1, focuses on the Partenavia P68 Series Aeroplanes, specifically those up to and including serial number 394, excluding serial number 391. This directive mandates detailed actions concerning the engine and propeller control cables (sections 1 and 2). The requirement is to inspect these cables in accordance with Partenavia Mandatory Service Bulletin 81 Revision 1. Furthermore, the directive specifies that the cables must be replaced according to the same bulletin revision (section 2). The compliance period is set to within 25 hours of time in service after 11 January 1995, and subsequently at intervals not exceeding 25 hours until the cables are replaced. This compliance must be completed prior to 11 January 1996 (section 3). The obligations imposed by this Act are clear and specific. Aircraft operators must adhere to the inspection and replacement schedule outlined in the Partenavia Mandatory Service Bulletin 81 Revision 1. This involves meticulous record-keeping to ensure that the required inspections and replacements are carried out within the stipulated timeframes. Operators must ensure that all personnel involved in the maintenance of the aircraft are adequately trained to perform these tasks according to the detailed guidelines provided. Failure to comply with these directives could result in significant safety risks, potentially leading to the failure of critical flight control systems. Breach of these directives can lead to serious consequences. The Civil Aviation Regulations 1998 outline penalties for non-compliance with safety directives, which may include both civil and criminal penalties. The specific consequences depend on the severity of the breach and the potential risk to flight safety. In severe cases, operators could face fines, suspension of operations, or even revocation of their operating certificates. Additionally, individuals responsible for the oversight of the non-compliance could face personal liability, including fines or imprisonment. The maximum penalties are not explicitly stated in the provided text but are generally severe, reflecting the critical importance of adhering to these safety directives to ensure the safety of all persons involved in air travel.
