AD/PA-30/17 Amdt 1 - Electrical Power Indicators - Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, are designed to ensure the safety and efficiency of civil aviation within Australian airspace. One such regulation, contained within Part 39 - 105, provides a schedule of airworthiness directives for various aircraft models, including the Piper PA-30 & 39 (Twin Comanche) Series Aeroplanes. This legislative instrument, specifically AD/PA-30/17 Amendment 1, was introduced to address the problem of inadequate electrical power monitoring in these aircraft models. The policy objective of this directive is to enhance the safety of flight operations by requiring the installation of an ammeter in each generator feeder line, thus providing flight crews with a means to continually monitor the current essential for the safe operation of the electrical system. Compliance with this directive is mandated forthwith, ensuring that all affected aircraft are modified to meet these safety standards promptly.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives pertaining to Piper PA-30 and 39 (Twin Comanche) Series Aeroplanes, applies to all aircraft models registered after 31 May 1972. This legislation mandates the installation of an ammeter in each generator feeder line to ensure that the flight crew can continually monitor the current essential for the safe operation of the system. The requirement underscores the critical need for real-time monitoring of electrical power indicators to maintain operational safety during flight. Compliance with this directive is immediate, as indicated by the term "forthwith," meaning that the mandated modifications must be completed without delay. The geographical and jurisdictional reach of this regulation is nationwide, affecting all registered Twin Comanche aircraft within Australia, and it does not explicitly state any exclusions, exemptions, or thresholds within the directive itself. Any further details or specifications concerning the implementation of these directives may be extended or clarified through subordinate instruments issued by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, include specific Airworthiness Directives (AD) that govern the safety standards for certain aircraft models. One such directive, AD/PA-30/17 Amendment 1, pertains to the Piper PA-30 and 39 (Twin Comanche) series aeroplanes and focuses on the installation of electrical power indicators (section 5/72). This directive applies to all models registered after 31 May 1972, and it requires the installation of an ammeter in each generator feeder line. The primary purpose of this requirement is to ensure that the flight crew has a continuous means to monitor the current, which is essential for the safe operation of the electrical system on board. Compliance with AD/PA-30/17 Amendment 1 involves installing an ammeter in each generator feeder line to provide the necessary current monitoring. Additionally, an ammeter that can be switched into the battery line and each generator feeder line may be used, provided the switch can be selected to a generator feeder line throughout the flight. This ensures that the flight crew has an immediate and reliable way to monitor the system's current, which is crucial for maintaining the safety and functionality of the aircraft's electrical system. The obligations imposed by this directive require the aircraft owners or operators to ensure that the specified modifications are carried out promptly. The directive mandates that these modifications be completed forthwith, meaning that the installation of the ammeter must be performed immediately without undue delay. Failure to comply with this directive can lead to serious safety issues, as the absence of a reliable means to monitor the electrical system's current can compromise the safe operation of the aircraft. The consequences of non-compliance with the Civil Aviation Regulations, including the requirements set out in AD/PA-30/17 Amendment 1, can be severe. While the specific penalties for breaching this particular directive are not detailed in the provided text, non-compliance with Civil Aviation Regulations generally can result in both civil and criminal penalties. These may include fines, imprisonment, or both, depending on the severity of the breach and its impact on aviation safety. The Civil Aviation Safety Authority has the authority to enforce these regulations and can take action against non-compliant aircraft or operators to ensure that safety standards are upheld.
