AD/PA-31/32 - Electrical Power Indicators - Modification

Overview

The Civil Aviation Regulations 1998, under the authority of the Civil Aviation Safety Authority, were enacted to ensure the safety and efficiency of civil aviation within Australia. A specific legislative instrument, F2006B05737, was introduced as an airworthiness directive (AD/PA-31/32) aimed at addressing issues concerning the electrical power indicators in Piper PA-31 series aeroplanes. The directive was issued to mitigate risks associated with inadequate monitoring of electrical power systems, which could potentially compromise the safe operation of these aircraft. By mandating the installation of an ammeter in each generator feeder line, the directive ensures that flight crews have continuous visibility of the current flowing through essential electrical systems, thus contributing to the overarching policy objective of maintaining high safety standards in civil aviation. This legislative measure was introduced in response to identified gaps in the monitoring and safety protocols of electrical systems in Piper PA-31 series aeroplanes. The requirement for an ammeter installation was specified to be completed within 200 hours of time in service after 30 August 1974, underscoring the urgency and importance of addressing these safety concerns. The directive reflects the Civil Aviation Safety Authority's commitment to ensuring that all aircraft meet stringent safety standards, thereby protecting both the flight crew and passengers.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, as outlined in the legislative instrument F2006B05737, pertains to the Piper PA-31 Series aeroplanes, stipulating mandatory modifications to ensure compliance with safety directives. This Act applies to all models of Piper PA-31 Series aeroplanes and mandates the installation of an ammeter in each generator feeder line to enable the flight crew to continually monitor the current, which is critical for the safe operation of the electrical system. The requirement must be fulfilled within 200 hours of time in service following the directive's issuance on 30 August 1974. This regulation operates under the jurisdictional authority of the Commonwealth of Australia and is enforced by the Civil Aviation Safety Authority. The Act does not provide for exclusions or exemptions, and compliance is strictly enforced to uphold safety standards across all applicable aircraft operations.

Key Provisions

The Civil Aviation Regulations 1998, particularly Part 39 - 105, include a Schedule of Airworthiness Directives which specifies the requirements for maintaining the airworthiness of aircraft. One such directive, AD/PA-31/32, pertains to the Piper PA-31 Series aeroplanes. This directive mandates the installation of an ammeter in each generator feeder line (section 8/74). The purpose of this requirement is to ensure that flight crews have a continuous means to monitor the current, which is essential for the safe operation of the electrical system (section 8/74). The directive applies to all models of the Piper PA-31 Series aeroplanes. Compliance with this directive must be achieved within 200 hours of time in service after 30 August 1974. The obligations imposed by this directive are straightforward yet critical. Operators and owners of Piper PA-31 Series aeroplanes must ensure that an ammeter is installed in each generator feeder line. The installation must be completed within the specified timeframe of 200 hours of time in service following the date of the directive. Additionally, if an ammeter capable of being switched into the battery line and each generator feeder line is used, the switch must be selectable to a generator feeder line throughout the flight. These obligations are essential to maintain the safety standards set forth by the Civil Aviation Safety Authority. Failure to comply with the requirements set out in AD/PA-31/32 can result in various consequences. Although the specific penalties are not detailed within the text of the directive, non-compliance with airworthiness directives is generally considered a breach of the Civil Aviation Regulations. Such breaches can lead to enforcement actions by the Civil Aviation Safety Authority, which may include fines, suspension or revocation of airworthiness certificates, and other regulatory penalties. These consequences underscore the importance of adhering to the specified requirements to ensure the continued safe operation of the aircraft.
