AD/PA-38/8 Amdt 3 - Engine Mount Tubes - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, enacted by the Parliament of the Commonwealth of Australia, form the foundation for regulating civil aviation within Australia. This legislation addresses gaps in aviation safety and operational standards to ensure the highest level of safety and efficiency in Australia's airspace. Specifically, Part 39 - 105 of the Civil Aviation Regulations includes directives for maintaining the airworthiness of various aircraft, such as the Piper PA-38 (Tomahawk) Series Aeroplanes. This part was introduced to fill the need for stringent and consistent safety standards across the aviation industry, ensuring all aircraft meet specific airworthiness requirements. The policy objective is to enhance aviation safety by enforcing regular inspections and modifications, as illustrated in the amendment concerning the engine mount tubes of the Piper PA-38 series aeroplanes. The Civil Aviation Safety Authority (CASA) schedules specific airworthiness directives, such as AD/PA-38/8 Amendment 3, to ensure ongoing compliance with safety standards. This particular directive targets the inspection and modification of engine mount tubes in PA-38-112 models with serial numbers ranging from 38-78A0001 to 38-78A0678. CASA's objective is to mitigate any potential safety risks by mandating specific maintenance actions as outlined in Piper Service Bulletin No. 617B. By extending the applicability to additional serial numbers, CASA reinforces its commitment to maintaining high safety standards and ensuring the continued airworthiness of these aircraft.

Scope and Application

The Civil Aviation Safety Authority (CASA) has issued a specific Airworthiness Directive under the Civil Aviation Regulations 1998, targeting the Piper PA-38 (Tomahawk) series aeroplanes. This directive applies to all models of the PA-38-112 series with serial numbers ranging from 38-78A0001 to 38-78A0678. The directive mandates inspection and modification of engine mount tubes to ensure compliance with safety standards. This directive is part of the broader regulatory framework overseen by CASA, ensuring that the specified aircraft maintain their airworthiness and adhere to safety regulations. The directive is applicable across the Commonwealth of Australia, reflecting CASA's jurisdiction over civil aviation safety nationwide. This particular amendment extends the applicability to additional serial numbers as detailed in Piper Service Bulletin No. 617B, thereby encompassing a broader range of aircraft within its scope.

Key Provisions

The main operative sections of the Civil Aviation Regulations 1998, particularly under Part 39 - 105, address airworthiness directives, which are legally enforceable rules to correct an unsafe condition on an aircraft. Section 39.105 focuses on the Piper PA-38 (Tomahawk) Series Aeroplanes, specifically AD/PA-38/8 Amendment 3. This amendment pertains to the inspection and modification of engine mount tubes, as detailed in Piper Service Bulletin (SB) No. 617B. This directive applies to all models of the PA-38-112 with serial numbers ranging from 38-78A0001 to 38-78A0678. Compliance with these regulations is mandatory, and operators must adhere to the requirements set forth in the referenced Piper SB No. 617B. The obligations imposed by this regulation are stringent and specific. Operators of the affected aircraft must ensure that the engine mount tubes are inspected and, if necessary, modified according to the specifications detailed in Piper SB No. 617B. This includes conducting thorough visual and dimensional inspections to detect any signs of wear, corrosion, or other defects. Should any issues be identified, the appropriate modifications must be carried out to bring the aircraft into compliance with airworthiness standards. Operators must maintain detailed records of all inspections and modifications performed, including dates, findings, and the actions taken to rectify any issues. Failure to comply with the airworthiness directives can lead to serious consequences. Under Section 97 of the Civil Aviation Act 1988, non-compliance with an airworthiness directive can result in substantial penalties. Civil penalties for non-compliance can include fines of up to $165,000 for corporations and $33,000 for individuals, depending on the severity of the breach. Additionally, criminal penalties can apply, with maximum fines of up to $1,650,000 for corporations and $330,000 for individuals. These stringent penalties underscore the importance of adhering to the airworthiness directives to ensure the safety of all passengers and crew onboard the affected aircraft.
