AD/TSA-600/20 - Fuel Filler Cap Leakage - Testing

Overview

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically address the safety directives for aircraft such as the Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes. Enacted by the Commonwealth of Australia, this legislation aims to ensure the airworthiness of these aircraft by issuing safety directives to mitigate risks identified through various tests and incidents. One such directive, AD/TSA-600/20, focuses on addressing fuel filler cap leakage issues that have been identified by the Federal Aviation Administration (FAA) as a potential safety hazard. The directive mandates rigorous testing and compliance with specified requirements to prevent fuel leakage, which could otherwise lead to fuel imbalance and forced landings, as experienced in the U.S.A. The policy objective is to enhance flight safety by ensuring that all Aerostar models adhere to stringent fuel system integrity standards.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, apply to all Aerostar (Piper/Ted Smith) 600 and 700 Series aeroplanes concerning the airworthiness directive AD/TSA-600/20, which mandates testing for fuel filler cap leakage. The regulation ensures compliance with the requirements outlined in Piper Aerostar Service Bulletin No. 600-77, Part II. It is imperative for all operators of these aircraft models to adhere to the detailed testing and maintenance procedures to prevent fuel leakage, which can critically affect fuel distribution and lead to safety issues such as forced landings. The directive applies to all Aerostar aeroplanes within the Commonwealth of Australia, aligning with national safety standards. There are no stated exclusions or exemptions in this directive; it applies uniformly to all relevant aircraft within the specified category, ensuring consistent safety measures across the aviation industry. The regulation may be extended or further specified through subordinate instruments, but the primary focus remains on maintaining the integrity of the fuel filler cap system to avoid safety hazards.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, contain detailed directives concerning the airworthiness of various aircraft models, including the Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes. Section AD/TSA-600/20 pertains to the issue of fuel filler cap leakage and mandates testing for all models of these aircraft (Section 6/79). This directive references Piper Aerostar Service Bulletin No. 600-77, Part II, which provides detailed compliance requirements. The importance of these directives stems from tests conducted by the Federal Aviation Administration (FAA) that revealed critical issues with fuel leakage past the wing tank filler caps. Such leakage can significantly reduce fuel flow to the fuselage tank, potentially causing premature depletion of the fuselage tank while leaving a substantial amount of fuel in the wing tanks. This condition has led to forced landings in the United States, underscoring the necessity of strict compliance with these regulations. The obligations imposed by this Act on the relevant parties, primarily aircraft operators and maintenance personnel, include conducting thorough tests and inspections to ensure that the fuel filler caps are maintaining a proper seal. This requirement extends to all models of the Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes. Operators must follow the detailed compliance instructions outlined in the referenced Piper Aerostar Service Bulletin No. 600-77, Part II. Ensuring compliance involves regular checks and maintenance procedures to prevent leakage, thereby maintaining the aircraft's airworthiness and safety. Maintenance personnel must be trained and certified to perform these tests and inspections, adhering strictly to the guidelines provided in the regulations. Failure to comply with the provisions of the Civil Aviation Regulations 1998, specifically under Section AD/TSA-600/20, can result in severe consequences. Any breach of these regulations may lead to both civil and criminal liabilities. The exact penalties are not specified in the provided text, but it is reasonable to infer that non-compliance could result in substantial fines, penalties, or even imprisonment, depending on the severity of the breach and its impact on flight safety. The potential for forced landings due to fuel system issues highlights the critical importance of adhering to these safety directives, making compliance a non-negotiable aspect of aircraft operation and maintenance.
