AD/PA-30/21 Amdt 1 - Uncoordinated Manoeuvres - Warning Placard

Overview

The Civil Aviation Regulations 1998, specifically Part 39 - 105, were enacted to regulate the airworthiness of aircraft and ensure the safety of aviation activities within Australia. The Civil Aviation Safety Authority (CASA) established this legislation to address the need for standardised airworthiness directives and to provide clear guidelines for maintaining aircraft safety. The policy objective of these regulations is to mitigate risks associated with uncoordinated manoeuvres by mandating the installation of warning placards on Piper PA-30 and PA-39 (Twin Comanche) series aeroplanes. The requirement for compliance within 100 hours of time in service after 31 July 1975 aims to ensure that pilots are promptly informed of the risks involved with uncoordinated manoeuvres, thereby enhancing flight safety. This legislative instrument, AD/PA-30/21 Amendment 1, is part of the ongoing efforts by CASA to enforce safety standards across the aviation industry.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, focusing on Piper PA-30 and 39 (Twin Comanche) Series Aeroplanes. This legislation applies to specific models within the Piper Twin Comanche series, namely PA-30 aircraft with serial numbers ranging from 30-1 to 30-2000 and PA-39 aircraft with serial numbers from 39-1 to 39-155. The regulation mandates compliance with the directive within 100 hours of time in service after 31 July 1975, ensuring that these aircraft meet safety standards and are equipped with the required warning placard as stipulated in Piper Service Bulletin No. 456A. This regulation extends across the Commonwealth of Australia, governed by the Civil Aviation Safety Authority, which oversees the implementation and enforcement of airworthiness directives to maintain safety standards within the aviation industry.

Key Provisions

The Civil Aviation Regulations 1998 (part 39 - 105) outline specific Airworthiness Directives (AD) for various aircraft models, including the Piper PA-30 and PA-39 series aeroplanes. Specifically, AD/PA-30/21 Amendment 1 focuses on the requirement to install a warning placard regarding uncoordinated manoeuvres (section 39-105). This directive applies to all Model PA-30 with serial numbers (S/Nos.) 30-1 to 30-2000 and Model PA-39 with S/Nos. 39-1 to 39-155. Compliance with this directive must be achieved within 100 hours of the aircraft’s time in service after 31 July 1975, as referenced in Piper Service Bulletin No. 456A. The primary obligation under this AD is for the aircraft owner or operator to ensure that the specified warning placard is installed in accordance with the manufacturer's instructions. This placard is intended to alert pilots to the dangers of uncoordinated manoeuvres, which can significantly increase the risk of structural failure or loss of control. Failure to adhere to this directive could result in the aircraft being deemed unairworthy, which would prevent it from being operated until the necessary compliance measures are implemented. Breach of this Airworthiness Directive can result in serious consequences. Firstly, the aircraft may be grounded, and operations can be suspended until the required placard is installed. Furthermore, under section 39-105 of the Civil Aviation Regulations 1998, non-compliance can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions could include administrative penalties, which can be substantial, depending on the severity and frequency of the breach. In more severe cases, CASA may also pursue legal action, which could result in higher penalties or even prosecution of the responsible parties. In terms of penalties, while specific monetary fines are not detailed in the text, the potential for financial repercussions is significant. Non-compliance can lead to fines that vary based on the nature and extent of the violation, as well as the regulatory discretion exercised by CASA. Additionally, criminal penalties could be imposed in cases of gross negligence or willful disregard of the regulations, potentially leading to imprisonment for the responsible individuals.
