AD/PA-38/9 - Slick Magneto/Condenser - Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Government, were established to ensure the safe operation of aircraft within Australian airspace. Among various amendments and updates, the regulations include a specific airworthiness directive, AD/PA-38/9, which was introduced in 1978 to address the safety concerns associated with the Slick Magneto/Condenser in Piper PA-38 (Tomahawk) Series Aeroplanes. This directive was necessitated by documented issues with the magnetos, particularly models 4050, 4051, and 4081, which could lead to engine failures. The policy objective behind AD/PA-38/9 is to mandate the replacement of these potentially faulty components to mitigate risks and ensure the continued airworthiness and safety of the affected aircraft. The directive requires compliance with the specifications provided by Lycoming Service Bulletin No. 432 or Piper Service Bulletin No. 620, underscoring the commitment to maintaining rigorous safety standards in civil aviation.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, concerns the Piper PA-38 (Tomahawk) series aeroplanes, with the Airworthiness Directive AD/PA-38/9 addressing the replacement of Slick Magneto/Condenser in model PA-38-112 fitted with Slick Magnetos models 4050, 4051 and 4081. This directive applies to aeroplanes within the specified models that are operating under the regulatory purview of the Civil Aviation Safety Authority (CASA) in Australia. The directive's scope is clear in its requirement for compliance with either Lycoming Service Bulletin No. 432 or Piper Service Bulletin No. 620, ensuring that the replacement of the Slick Magneto/Condenser is performed in accordance with the specified guidelines. The legislation extends its applicability nationally, impacting all operators of the affected Piper PA-38 aeroplanes within Australia, ensuring a standardised approach to airworthiness across the industry.

Key Provisions

The Civil Aviation Regulations 1998 (Cth), Part 39, specifically under the Airworthiness Directives for Piper PA-38 (Tomahawk) Series Aeroplanes, mandates the replacement of slick magnetos in models PA-38-112 fitted with Slick Magnetos Models 4050, 4051, and 4081. This directive is outlined in AD/PA-38/9, which requires compliance with either Lycoming Service Bulletin No. 432 or Piper Service Bulletin No. 620. The directive is applicable to ensure the continued airworthiness of the aircraft, aiming to address known issues with the magnetos that could affect flight safety. Entities governed by this directive, primarily aircraft owners and operators, have a duty to ensure that the specified slick magnetos are replaced according to the instructions provided in either Lycoming SB No. 432 or Piper SB No. 620. This includes timely notification to the Civil Aviation Safety Authority (CASA) upon completion of the required replacement, ensuring that the aircraft remains compliant with airworthiness standards. Failure to comply with these directives may result in the aircraft being deemed unairworthy, potentially leading to grounding and other regulatory actions. The regulations impose serious consequences for non-compliance with the Airworthiness Directives. The Civil Aviation Safety Authority has the authority to enforce compliance and may take action against non-compliant aircraft. This can include fines, enforcement notices, or even criminal charges against the aircraft owners or operators if the non-compliance is found to have endangered flight safety. The maximum penalties can be significant, reflecting the seriousness of maintaining airworthiness standards to ensure public safety in aviation.
