AD/PA-32/29 - Rudder Bar Assembly - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority (CASA) under the Civil Aviation Act 1988, are designed to ensure the safety of civil aviation in Australia. These regulations were enacted to fill a critical gap in maintaining the airworthiness of aircraft, addressing concerns about the safety of Piper PA-32 (Cherokee Six) Series Aeroplanes. The objective of this legislation is to ensure that these aircraft meet the necessary safety standards by requiring specific inspections and modifications. The Piper PA-32 (Cherokee Six) Series Aeroplanes Rudder Bar Assembly Inspection and Modification directive, detailed in the Civil Aviation Regulations, mandates that inspections must be conducted within 100 hours of time in service after 31 December 1973 and at intervals not exceeding 100 hours thereafter until the modification is completed. Compliance with Service Letter No. 671 is also required, with modifications to be made not later than the first major inspection following 31 December 1973, ensuring that these aircraft meet the required safety standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, apply to all Piper PA-32 (Cherokee Six) Series Aeroplanes. This legislation mandates the inspection and modification of the rudder bar assembly for all variants of the mentioned aircraft, with the aim of ensuring airworthiness and safety standards are met. The application of these regulations is overseen by the Civil Aviation Safety Authority (CASA), thereby establishing a national scope for compliance. The directive applies to all operators and owners of Piper PA-32 aeroplanes within Australia, necessitating adherence to the specified inspection intervals and modification requirements outlined in Piper Service Letter No. 671. The regulations do not exclude any specific entities or operations, ensuring uniform safety standards across the aviation industry. Compliance is mandatory, with inspections required every 100 hours of service after 31 December 1973, and modifications must be made before the first major inspection following that date. The enforcement of these regulations is critical to maintaining the safety and reliability of the specified aircraft models in Australian airspace.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39, include provisions that pertain to the airworthiness directives for various aircraft, such as the Piper PA-32 (Cherokee Six) Series Aeroplanes. One notable directive, AD/PA-32/29, mandates the inspection and modification of the rudder bar assembly (section 12/73). This directive applies to all models of the aircraft and references Piper SL No. 671 for detailed compliance instructions. The requirement is to inspect the rudder bar assembly within 100 hours of time in service after 31 December 1973 and subsequently at intervals not exceeding 100 hours time in service until the modification is completed. Furthermore, the rudder bar assembly must be modified in accordance with the specifications outlined in SL No. 671 by the time of the first major inspection following 31 December 1973. The obligations imposed by this directive are clear and specific. Operators and owners of the Piper PA-32 (Cherokee Six) Series Aeroplanes must ensure that the rudder bar assembly is inspected and, if necessary, modified as per the stipulated timelines and instructions. This includes maintaining records of inspections and modifications, which are crucial for demonstrating compliance with the airworthiness directives. The directive requires operators to adhere to the prescribed intervals for inspections and to complete the modification before the next major inspection, ensuring the aircraft remains airworthy and meets safety standards. Failure to comply with the provisions of AD/PA-32/29 can lead to serious consequences. Under the Civil Aviation Regulations 1998, non-compliance with airworthiness directives can result in various penalties and legal repercussions. The severity of the penalty often depends on the nature and extent of the breach. Civil penalties may include fines, while criminal penalties can result in imprisonment. The maximum penalties are determined by the seriousness of the offence and can vary widely. Operators who fail to adhere to the inspection and modification requirements may face significant fines and potential imprisonment for more severe breaches, highlighting the importance of strict compliance with the directive.
