Except those aircraft fitted with ninety (90) ampere alternators.
Requirement: Action in accordance with Piper Service Bulletin No. 811A. Ensure the shunt is positioned and adequately supported to prevent mechanical loads being applied to the 20 gauge wires connected to the ammeter.
Compliance: Within 100 hours time in service after 31 July 1986.
Background: Reports have been received of loose and/or shorting ammeter connections at the ammeter cluster gauge. If this condition is allowed to continue without rectification the possibility exists for electrical failure or a fire within the cockpit. Amendment 1 clarifies the protection requirements.
Overview
The Civil Aviation Regulations 1998, specifically Part 39 - 105, was enacted to address the issue of ensuring the airworthiness of aircraft in Australian airspace. The legislation aims to establish and enforce standards that ensure the safety and efficiency of civil aviation within the country. This was enacted by the Parliament of the Commonwealth of Australia, with the policy objective of protecting the public by ensuring that aircraft meet stringent safety standards. One of the Airworthiness Directives under this regulation, AD/PA-28/86 Amendment 1, targets the installation of ammeters in certain Piper PA-28 Series aeroplanes to prevent potential electrical failures or fires due to loose or shorting ammeter connections at the ammeter cluster gauge. The directive requires compliance within 100 hours of the aircraft being in service after 31 July 1986, ensuring the safety of affected aircraft models by following the specifications outlined in Piper Service Bulletin No. 811A.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, addresses the Airworthiness Directives for certain Piper PA-28 Series aeroplanes, as detailed in AD/PA-28/86 Amendment 1. This legislation applies to specific Piper PA-28 aeroplanes with serial numbers within the specified ranges. Notably, the directive does not apply to aircraft equipped with a 90-ampere alternator. The primary objective of this regulation is to ensure the safety of the aircraft by addressing the potential risk of electrical failure or fire due to loose or shorting ammeter connections. Operators of these aircraft must comply with the directive by implementing the measures outlined in Piper Service Bulletin No. 811A, which includes ensuring that the shunt is properly positioned and supported to prevent mechanical loads on the 20-gauge wires connected to the ammeter. Compliance is required within 100 hours of time in service after 31 July 1986. The regulation extends its reach to all operators of the affected aircraft within the Australian jurisdiction, overseen by the Civil Aviation Safety Authority.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates certain actions to ensure the safety and airworthiness of Piper PA-28 Series aeroplanes. Section AD/PA-28/86 Amendment 1 addresses the installation of ammeters on specific Piper PA-28 aircraft models, with serial numbers detailed within the document. The directive applies to PA-28-150/160, PA-28-180, PA-28-181, PA-28-235, PA-28-236, PA-28-201T, PA-28R-180, PA-28R-200, PA-28R-201, PA-28R-201T, PA-28RT-201, and PA-28RT-201T models, excluding those equipped with ninety (90) ampere alternators. The primary requirement outlined in this amendment is to adhere to Piper Service Bulletin No. 811A, ensuring the shunt is appropriately positioned and supported to prevent mechanical loads on the 20 gauge wires connected to the ammeter. This action must be completed within 100 hours of the aircraft being in service after 31 July 1986.
The regulations impose specific obligations on the owners or operators of the affected Piper PA-28 Series aircraft. These obligations include ensuring that the necessary modifications are made to the ammeter installation as specified in the Piper Service Bulletin No. 811A, and that these modifications are completed within the stipulated timeframe of 100 hours after 31 July 1986. The rationale behind this directive is to mitigate the risk of electrical failures or fires in the cockpit, which could result from loose or shorting ammeter connections. The compliance with this directive is crucial to maintaining the airworthiness of the aircraft and ensuring the safety of all onboard.
Failure to comply with the requirements set forth in this airworthiness directive may result in severe consequences. While the specific penalties are not detailed within the text, it is implied that non-compliance could lead to civil or criminal penalties under the broader framework of the Civil Aviation Regulations 1998. These penalties could include fines, operational restrictions, or even the grounding of the aircraft until the required modifications are made. The exact nature and severity of the penalties would depend on the specific circumstances and the enforcement actions taken by the Civil Aviation Safety Authority (CASA). Nonetheless, adherence to these directives is imperative to avoid any legal or safety repercussions.
