COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Piper PA-46 (Malibu) Series Aeroplanes
AD/PA-46/11 De-Ice Pressure Control Valve 6/86 DM
Applicability: 1. All model S/Nos 46-8408001 to 46-8508018
2. All model S/Nos 46-8408001 to 46-8508018 fitted with Hose kit Part No 765-159 and S/Nos 46-8508019 to 46-8508029.
Requirement: Action in accordance with Piper Service Bulletin No 803A.
Compliance: 1. Prior to the next flight into icing conditions, after 16 May 1986 and thereafter every 25 hours until kit, Piper Part No 765-159V, is installed.
2. Within 25 hours time in service after 16 May 1986 and thereafter every 50 hours until the Pressure Control Valve Piper Part No 84523-4 is replaced by Part No 845423-805.
Background: BF Goodrich, manufacturer of the pneumatic de-ice components used in the Malibu, have advised that a sticking condition will occur to the Pressure Control Valve due to carbon residue from the vacuum pump mixed with a waxy substance which is extracted from the hoses in the system.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, provide comprehensive safety standards and requirements for civil aviation operations within Australia. One specific legislative instrument within these regulations is AD/PA-46/11, which addresses a critical safety issue concerning Piper PA-46 (Malibu) Series Aeroplanes. This directive was introduced to address the problem of a sticking condition in the de-ice pressure control valve, which could be caused by carbon residue from the vacuum pump mixing with a waxy substance extracted from the hoses in the system. This issue was identified by BF Goodrich, the manufacturer of the pneumatic de-ice components. The policy objective behind AD/PA-46/11 is to ensure the continued airworthiness of affected aircraft by mandating specific actions to mitigate the risk of the identified sticking condition, thus enhancing overall aviation safety.
The directive applies to all model serial numbers 46-8408001 to 46-8508018 and those fitted with a particular hose kit. The required action is in accordance with Piper Service Bulletin No 803A, which must be followed before any flight into icing conditions after 16 May 1986, and then every 25 hours until the necessary parts are installed. Compliance also requires replacing the pressure control valve within 25 hours after 16 May 1986 and every 50 hours thereafter until the specified part is replaced. This directive is part of the broader regulatory framework designed to maintain and enhance the safety standards of civil aviation in Australia.
Scope and Application
The Civil Aviation Safety Authority's Airworthiness Directive (AD) for Piper PA-46 (Malibu) Series Aeroplanes, specifically AD/PA-46/11, applies to all Malibu aircraft with serial numbers ranging from 46-8408001 to 46-8508018, as well as those within the same range fitted with a specific hose kit and additional serial numbers from 46-8508019 to 46-8508029. The directive mandates compliance with Piper Service Bulletin No 803A to address issues with the de-ice pressure control valve. Operators of these aircraft must ensure that specific actions are taken: the installation of a hose kit, part number 765-159V, must be completed before the next flight into icing conditions after 16 May 1986, and then every 25 hours until the installation is complete. Additionally, the replacement of the pressure control valve with a new part, number 84523-4, by part number 845423-805, must occur within 25 hours of service after 16 May 1986, and then every 50 hours until the replacement is made. This directive is applicable across the Commonwealth of Australia and is enforced by the Civil Aviation Safety Authority, with potential extensions or restrictions through subordinate instruments.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the compliance with Airworthiness Directives (AD) for certain aircraft models. In this context, AD/PA-46/11 pertains to Piper PA-46 (Malibu) Series Aeroplanes, focusing on the de-ice pressure control valve (section 1). This directive applies to all Malibu series aeroplanes with specific serial numbers, as well as those fitted with a particular hose kit (section 2). The required action, as outlined in Piper Service Bulletin No 803A, must be followed to ensure compliance (section 3).
The directive imposes specific obligations on the operators and owners of the affected Piper PA-46 series aeroplanes. Compliance must be achieved by adhering to the actions specified in Piper Service Bulletin No 803A, which includes replacing certain parts of the de-ice system (section 4). Operators must ensure that the aircraft meets the specified requirements before flying into icing conditions and within certain time intervals after 16 May 1986 (section 5). Specifically, they must either install the specified kit or replace the pressure control valve according to the stipulated hours of service (section 6).
Failure to comply with the AD/PA-46/11 could result in significant civil or criminal consequences. While the exact penalties are not specified within the provided text, non-compliance with airworthiness directives under the Civil Aviation Regulations 1998 could lead to enforcement actions by the Civil Aviation Safety Authority (CASA). These actions could include fines, suspension or revocation of aircraft certificates, and other regulatory penalties. Additionally, non-compliance may also have implications for the safety of the aircraft, potentially leading to more severe consequences in the event of an accident or incident.
