AD/TSA-600/1 Amdt 1 - Pilot Seat Back-Rest Attach Bolt - Inspection and Replacement

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, serve to regulate civil aviation safety, with a key objective being the maintenance of airworthiness standards to ensure the safety of all aircraft operations within Australian airspace. The Regulations are administered by the Civil Aviation Safety Authority (CASA), which is responsible for ensuring compliance with safety directives. One such directive, AD/TSA-600/1, addresses the inspection and replacement of pilot seat back-rest attach bolts for Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes, reflecting a commitment to rectifying specific safety issues identified within these aircraft models. This directive, published in 1976, was introduced to address the risk associated with the integrity of pilot seat back-rest attach bolts, ensuring that these critical components meet the required safety standards to prevent potential in-flight failures.

Scope and Application

The Civil Aviation Safety Authority (CASA) regulates the airworthiness of aircraft through various regulations and directives, including those found in the Civil Aviation Regulations 1998, Part 39 - 105, which concerns the Schedule of Airworthiness Directives. Specifically, Airworthiness Directive AD/TSA-600/1 Amendment 1 pertains to the inspection and replacement of the pilot seat back-rest attach bolt for Aerostar (Piper/Ted Smith) 600 and 700 Series Aeroplanes. This directive applies to all models equipped with pilot seats manufactured by Frazier Aviation Inc. or Ted Smith Aerostar Corp. The directive specifies compliance requirements, with the inspection and replacement of the bolt mandated prior to further flight for parts I and II, while parts III and IV must comply within 200 hours of time in service after 5 November 1976. The directive is underpinned by Ted Smith Corp. Service Bulletin SB600-51, and its jurisdictional reach is governed by the Commonwealth of Australia.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, contain the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. One such directive, AD/TSA-600/1 Amendment 1, pertains to the Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes. This directive focuses on the pilot seat back-rest attach bolt, necessitating inspection and replacement. The directive applies to all models with pilot seats manufactured by Frazier Aviation Inc. or Ted Smith Aerostar Corp. (Section 11/76). The directive mandates that all Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes with the specified pilot seats undergo specific inspections and maintenance actions. Parts I and II of the directive require these actions to be completed prior to any further flight after 5 November 1976. Parts III and IV mandate that these actions be carried out within 200 hours of time in service following 5 November 1976. This directive is documented in Ted Smith Corp. Service Bulletin No. SB600-51 (Section 11/76). Compliance with AD/TSA-600/1 Amendment 1 is crucial for operators of the affected aeroplanes. Operators must ensure that the specified parts of the pilot seat back-rest attach bolt are inspected and replaced as required. This includes ensuring that any identified issues are resolved before the aeroplane is flown again, and that the required maintenance is performed within the specified timeframes. Failure to comply with this directive could result in serious safety risks and potential regulatory action. Breaching the requirements of AD/TSA-600/1 Amendment 1 can lead to significant consequences. Civil Aviation Regulations 1998 outline potential penalties for non-compliance with airworthiness directives. While the specific penalties for this directive are not detailed in the provided text, general provisions under the Civil Aviation Act 1988 may apply. These can include fines, operational restrictions, and potential criminal charges for serious breaches that result in safety hazards. Operators must be diligent in adhering to the directive to avoid these repercussions. In summary, AD/TSA-600/1 Amendment 1 is a critical directive for the safety of Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes. Operators must ensure compliance by inspecting and replacing the pilot seat back-rest attach bolt as specified, with strict adherence to the timelines provided. Non-compliance can result in severe civil and criminal penalties, underscoring the importance of following the directive to maintain airworthiness and safety standards.
