AD/PA-32/22 - Pitch Trim Switch - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, serve as a critical framework governing all aspects of civil aviation within the country, including the maintenance and safety standards for aircraft. Among the various parts of these regulations, Part 39 addresses airworthiness directives, ensuring that all aircraft meet the necessary safety standards. The policy objective behind these regulations is to safeguard the public and ensure the safe operation of aircraft by enforcing stringent safety protocols and standards. One specific instance of these regulations in action is found in the Airworthiness Directives for the Piper PA-32 (Cherokee Six) series aeroplanes, which mandate modifications to the pitch trim switch to address identified safety concerns. These directives, such as AD/PA-32/22, are designed to mitigate risks by requiring compliance within a specified timeframe, thus reinforcing the overarching goal of maintaining high safety standards in civil aviation. The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority, were introduced to fill the gap in comprehensive aviation safety standards in Australia. The regulations aim to ensure that all aircraft operations adhere to strict safety and maintenance protocols. By issuing specific airworthiness directives like AD/PA-32/22, which mandates modifications to the pitch trim switch on certain Piper PA-32 models, the regulations directly address identified safety issues. This targeted approach ensures that specific aircraft meet the necessary safety standards, thereby protecting both the crew and passengers. The directives require compliance within a defined period, emphasising the importance of timely adherence to safety measures.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the application of airworthiness directives that are mandated by the Civil Aviation Safety Authority (CASA) for ensuring the safe operation of aircraft within Australia. This particular legislation applies to all Piper PA-32 (Cherokee Six) series aeroplanes, including specific models and serial numbers, that are equipped with a rocker type pitch trim switch on the pilot’s control wheel. The directive is intended to ensure that these aircraft meet the necessary safety standards to operate in Australian airspace. The scope of this directive includes all model PA32-260 with serial numbers ranging from 32-1111 to 32-1297 and 32-7100001 to 32-7100017, and all model PA32-300 with serial numbers from 32-40566 to 32-40974 and 32-7140001 to 32-7140049. Compliance with the directive is required within 200 hours of time in service after the directive was issued on 30 July 1971. The regulations extend to the national level, ensuring that all specified aircraft operating in Australia adhere to these safety measures. This directive is binding across the Commonwealth of Australia and applies to both private and commercial operators of the specified aircraft models. The legislation does not specify any exclusions or exemptions, indicating that all affected aircraft must comply with the outlined safety requirements.

Key Provisions

The Civil Aviation Regulations 1998, specifically within PART 39 - 105, details the Airworthiness Directives for various aircraft, including the Piper PA-32 (Cherokee Six) Series Aeroplanes. In this instance, AD/PA-32/22 pertains to the modification of the pitch trim switch on these aircraft (Section 105). This directive is applicable to all model PA32-260 with serial numbers (S/Nos.) ranging from 32-1111 to 32-1297 and 32-7100001 to 32-7100017, as well as all model PA32-300 with S/Nos. 32-40566 to 32-40974 and 32-7140001 to 32-7140049, which are fitted with a rocker type trim switch on the pilot's control wheel (Section 105). Under these regulations, the modifications to the pitch trim switch must be carried out in compliance with Piper Service Bulletin No. 332. The compliance requirement is stringent, mandating that these modifications be completed within 200 hours of time in service after the directive's issue date, which is 30 July 1971 (Section 105). This timeline ensures that the safety improvements are implemented promptly to mitigate any potential risks associated with the identified issue. Operators and owners of the affected Piper PA-32 aircraft are obligated to adhere to these directives to maintain the airworthiness of their aircraft. This involves ensuring that the specified modifications to the pitch trim switch are performed by certified personnel and that any necessary documentation is updated to reflect compliance with the Airworthiness Directive. Failure to comply with these requirements can result in serious safety implications and potential legal repercussions. In the event of non-compliance, there are both civil and criminal consequences that can be imposed. The Civil Aviation Safety Authority (CASA) has the authority to enforce penalties for breaches of the Civil Aviation Regulations 1998. The specific penalties can include fines and, in more severe cases, prosecution that may result in imprisonment. The exact penalties are determined based on the severity and nature of the breach, with maximum penalties potentially reaching significant levels to ensure the importance of compliance is upheld.
