AD/TSA-600/9 - Alternator Field Circuit Protection - Modification

Overview

The Civil Aviation Regulations 1998 were enacted by the Australian Parliament to regulate civil aviation safety and ensure compliance with international standards. This particular legislative instrument, known as the Civil Aviation Regulations 1998, Part 39 - 105 Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically addresses the safety of Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes. The instrument was introduced to fill the gap in ensuring the airworthiness of these specific models, particularly by modifying the alternator field circuit protection as mandated by AD/TSA-600/9. The policy objective is to enhance aviation safety by mandating specific modifications to aeroplanes to prevent potential malfunctions that could lead to accidents. The enactment of this regulation by the Civil Aviation Safety Authority (CASA) aims to provide clear and enforceable directives to maintain the safety standards of aircraft in operation. This is achieved by specifying the applicability of the modifications to particular serial numbers of the Aerostar 600 and 700 Series, ensuring that these aeroplanes meet the required safety standards within a stipulated time frame after a specified date. This ensures that the identified safety issues are systematically addressed, thereby reducing the risk of in-flight incidents.

Scope and Application

The Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, specifically AD/TSA-600/9, pertains to the Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes, targeting particular serial number ranges within these models to ensure compliance with safety regulations. The directive applies to specific models and serial numbers of Aerostar aeroplanes, necessitating modifications to the alternator field circuit protection. This directive is binding for all Aerostar 600, 601, and 601P models with the specified serial numbers, ensuring that these aircraft meet critical safety standards within a defined timeframe. The compliance requirement mandates that the necessary modifications be implemented within 200 hours of time in service following the directive's issuance date of 31 July 1977. The directive's scope is limited to these particular aircraft models and serial numbers, and compliance is essential to maintain the airworthiness of the specified aeroplanes under Australian civil aviation regulations.

Key Provisions

The Civil Aviation Regulations 1998, particularly within Part 39, contain detailed provisions governing the airworthiness of various aircraft, including specific directives for certain aeroplane models. Section 39-105 of the Act pertains to the Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes, with a particular focus on the modification of the alternator field circuit protection (AD/TSA-600/9). This directive was issued on 7/77 and specifies the applicability and compliance requirements for certain serial numbers of these aircraft models. The key requirement of this directive is that specific Aerostar models must undergo an alteration to their alternator field circuit protection to enhance safety. This is outlined in Part 1 of the directive for serial numbers ranging from 60-0001-003 to 60-0189-085, and in Part 11 for serial numbers ranging from 60-0190-086 to 61-0352-114, among others. Compliance with these directives must be achieved within 200 hours of time in service after 31 July 1977, as indicated in the document issued by Ted Smith Corp. SB No. SB600-54. Aircraft owners and operators governed by this Act must ensure that the specified modifications are performed by certified technicians in accordance with the provided documentation. Failure to comply with these directives can result in the aircraft being deemed unairworthy, potentially leading to grounding or other enforcement actions by the Civil Aviation Safety Authority (CASA). Additionally, any deviation from these requirements could lead to significant operational disruptions and increased risk of accidents, which is a critical consideration under aviation safety regulations. The Act also outlines potential consequences for non-compliance with these airworthiness directives. Any breach of the specified requirements may result in civil penalties, with maximum fines potentially imposed under relevant aviation regulations. Furthermore, continued operation of a non-compliant aircraft may lead to criminal charges and penalties, reflecting the high priority placed on aviation safety and compliance by regulatory authorities. These measures underscore the importance of adhering to airworthiness directives to maintain the safety and reliability of aircraft operations.
