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-46/12 Alternate Air Control Linkage 1/87
Applicability: Piper PA-46 aircraft which have complied with Service Letter No 985 Part II, dated 18 April 1986.
Requirement: Action in accordance with Piper Service Bulletin No 852.
Compliance: Unless previously accomplished, prior to the issue of the next Maintenance Release after 31 January 1987.
Background: The manufacturer has determined through engineering tests that conditions may exist that would prevent selection of alternate induction air when the primary air source is cut off. Two reports of engine power loss have been attributed to this condition.
Overview
The Civil Aviation Regulations 1998, as amended by the Legislative Instrument F2006B06019, were enacted to enhance the safety standards within the civil aviation industry in Australia. This specific legislative instrument addresses a critical gap in the safety protocols concerning Piper PA-46 (Malibu) series aeroplanes by issuing Airworthiness Directives (AD) to ensure the integrity and safety of these aircraft. The enacting body, the Australian Parliament, introduced this regulation to mitigate risks associated with engine power loss due to the failure of the alternate air control linkage, as evidenced by two reported incidents. The policy objective is to mandate compliance with the manufacturer's recommendations through service bulletins, ensuring that aircraft maintain operational safety and reliability by adhering to the stipulated maintenance schedules.
This regulation is a proactive measure to enforce compliance with Piper Service Bulletin No 852 for Piper PA-46 aircraft that have met the criteria set out in Service Letter No 985 Part II, dated 18 April 1986. The requirement necessitates that corrective actions be completed before the next maintenance release following 31 January 1987, thereby reinforcing the commitment to preventing future incidents related to the alternate air control linkage.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to airworthiness directives issued by the Civil Aviation Safety Authority (CASA) for ensuring the safety and compliance of aircraft within Australia's jurisdiction. This particular legislative instrument, AD/PA-46/12, applies to Piper PA-46 (Malibu) series aeroplanes that have adhered to Service Letter No 985 Part II dated 18 April 1986. The directive mandates action in accordance with Piper Service Bulletin No 852 to address a condition that may prevent the selection of alternate induction air when the primary air source is cut off. Compliance with this directive is required before the issuance of the next Maintenance Release following 31 January 1987. This regulation underscores CASA's commitment to ensuring the safety of civil aviation by mandating specific maintenance actions on affected aircraft, thereby mitigating potential risks associated with the identified condition.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, detail the requirements for maintaining the airworthiness of Piper PA-46 (Malibu) series aeroplanes through various airworthiness directives. One such directive is AD/PA-46/12, which pertains to the Alternate Air Control Linkage (section 1/87). This directive applies to Piper PA-46 aircraft that have complied with Service Letter No 985 Part II, dated 18 April 1986 (section 1/87). The directive mandates that action must be taken in accordance with Piper Service Bulletin No 852 (section 1/87). This action must be completed unless it has already been carried out, before the issuance of the next Maintenance Release after 31 January 1987 (section 1/87).
Under this legislation, the obligations for the parties governed include ensuring that the specified maintenance actions are carried out on the Piper PA-46 aircraft. This involves following the procedures outlined in Piper Service Bulletin No 852, which aims to rectify the identified issue with the alternate air control linkage. The purpose is to prevent conditions that could lead to engine power loss by ensuring the alternate induction air can be selected when the primary air source is cut off. The compliance must be verified and documented appropriately to demonstrate that the required maintenance has been completed and to maintain the aircraft's airworthiness.
Failure to comply with the requirements set out in AD/PA-46/12 could result in serious consequences. If an aircraft does not meet the maintenance directive, it may be deemed unairworthy, leading to potential grounding of the aircraft. Additionally, there may be civil or criminal penalties imposed for non-compliance with airworthiness directives. Although specific penalties are not detailed in the provided excerpt, regulatory breaches under the Civil Aviation Regulations 1998 can result in significant fines and other enforcement actions. The severity of the penalties may depend on the nature and extent of the non-compliance, as well as any resultant safety implications.
