Overview

The Civil Aviation Regulations 1998, specifically PART 39 - 105, addresses the maintenance and safety standards for aircraft operating in Australian airspace. Enacted by the Parliament of the Commonwealth of Australia, this legislation aims to ensure the highest standards of safety and reliability in civil aviation. The policy objective is to mitigate risks associated with aircraft operations through stringent oversight and mandatory compliance with airworthiness directives. One such directive, AD/PA-34/21, pertains to the rudder cable installation of Piper PA-34 (Seneca) Series aeroplanes, specifically models PA34-200T with certain serial numbers. This directive was introduced to address potential safety hazards related to the rudder cable system, ensuring that any issues are identified and rectified before further flight operations. The directive mandates that operators gain access to the aft rudder cable pulleys and verify the position of the rudder cable guard pin. If the pin is found in the 3 o'clock position, it requires an inspection for cable fraying, with replacement necessary if fraying is detected. This regulation seeks to prevent potential malfunctions that could compromise flight safety, thereby upholding the overarching goal of maintaining the integrity and safety of civil aviation in Australia.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses airworthiness directives which include detailed safety requirements for aircraft operation. This legislative instrument focuses on the Piper PA-34 (Seneca) series aeroplanes, with a particular mandate concerning rudder cable installation in the rear fuselage. The directive applies to specific model PA34-200T aircraft within defined serial number ranges. The directive requires thorough inspections and actions to be taken if specific conditions regarding the rudder cable guard pin are not met, which includes inspecting for fraying and replacing the cable if necessary. Compliance with these regulations is mandatory prior to further flight after the specified date of 9 March 1977. This regulation is enforced by the Civil Aviation Safety Authority, and adherence to these directives ensures the continued airworthiness of the affected aircraft. The application of this regulation is geographically and jurisdictionally broad, falling under the Commonwealth of Australia, and therefore applies nationally across all states and territories. There are no specific exclusions, exemptions, or thresholds mentioned within this directive. The regulation extends its application through subordinate instruments that provide detailed inspection and compliance procedures.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 – 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives for Piper PA-34 (Seneca) Series Aeroplanes, outlines a specific directive (AD/PA-34/21) concerning the rudder cable installation in the rear fuselage (paragraphs 1-5). The directive mandates a specific inspection procedure for aircraft owners or operators of model PA34-200T with certain serial numbers. Primarily, it requires gaining access to the aft rudder cable pulleys through either the ELT access panel or the aft cabin bulkhead. Once access is gained, the position of the rudder cable guard pin relative to the centre of the pulley must be determined using a torch and/or an inspection mirror, specifically checking if it is in the 12 o’clock or 3 o’clock position when viewed from the ELT access hole. If the rudder cable guard pin is found in the 12 o’clock position, no further action is required according to the directive. However, if the pin is in the 3 o’clock position, the next step involves inspecting the cable for any signs of fraying. If fraying is evident, the cable must be replaced. Following this inspection and any necessary replacement, the cable guard pin must be relocated and installed in the holes at the 12 o’clock position. The obligations imposed by this directive are clear and specific. Aircraft owners or operators must ensure that the inspection and any necessary corrective actions are carried out before further flight. Compliance with this directive is mandatory and must be achieved prior to any further flight after 9 March 1977. Failure to comply with the provisions of this directive could have serious implications. While specific penalties are not detailed within the directive itself, non-compliance with Civil Aviation Regulations can result in significant civil or criminal penalties, including fines and potential grounding of the aircraft. The exact penalties would be determined in accordance with other relevant sections of the Civil Aviation Act 1988 and associated regulations.
