Overview

The Civil Aviation Regulations 1998, enacted by the Commonwealth of Australia, establish a comprehensive framework for ensuring the safety and efficiency of civil aviation within the country. Specifically, Part 39 - 105 of the Civil Aviation Regulations 1998 focuses on airworthiness directives, which are legally enforceable rules issued by the Civil Aviation Safety Authority (CASA) to correct an unsafe condition of a product. This particular legislative instrument, F2006B07492, pertains to Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes, addressing the identified safety issue of potential fuel leaks from Aerosonic Fuel Flow Transducers. The policy objective of this directive is to mitigate the risk of fuel leaks by mandating regular inspection and replacement of specified transducers, thereby enhancing aviation safety and preventing potential accidents. Compliance with this directive is required within specified timeframes to ensure ongoing airworthiness of the affected aircraft.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates compliance with certain airworthiness directives, including AD/TSA-600/27, which concerns Aerostar (Piper/Ted Smith) 600 and 700 series aeroplanes. This directive applies to all Piper Aerostar models 600, 601, and 601P.11/80 and mandates that all installed Aerosonic Fuel Flow Transducers must be inspected for fuel leaks where the transducer cap and body are bonded together. Furthermore, certain Aerosonic Fuel Flow Transducers must be replaced, torqued to specified levels, and followed by a system leak check. The requirement is to inspect the transducers within 25 hours of service after 13 October 1980 and every 25 hours thereafter until the specified replacements are made. Transducers revealing fuel leaks must be replaced before further flight. This directive ensures that the potential for fuel leaks due to improper bonding of the transducer caps is mitigated, thereby preventing hazardous conditions such as engine compartment fires.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, address the safety directives for Aerostar (Piper/Ted Smith) 600 and 700 Series aeroplanes, with particular focus on the Aerosonic fuel flow transducers in AD/TSA-600/27. Section 1 of this directive requires that all installed Aerosonic Fuel Flow Transducers for Piper Aerostar Models 600, 601, and 601P must be inspected for any fuel leaks at the junction where the transducer cap and body are bonded together. Furthermore, certain transducers, identified by part numbers 33184-1 and 32622-6, must be replaced unless they are marked with the word “FLO-SCAN” on the bottom of the transducer. The replacement units must be Aerosonic and identified with "FLO-SCAN" serial numbers 5000 and above. Additionally, the fittings should be torqued to 25-30 ft. lbs., and a system leak check must be performed. The obligations imposed by these regulations are stringent and clear. Operators of the specified Piper Aerostar models must conduct inspections within 25 hours of time in service following the directive’s publication date of 13 October 1980, and subsequently, every 25 hours of time in service. Transducers that reveal any fuel leaks in the specified area must be replaced before any further flight. This ensures the continuous maintenance of airworthiness standards and mitigates the risk of fuel leaks and potential fires. The consequences for non-compliance with these regulations are significant. If operators fail to adhere to the inspection and replacement requirements, they risk compromising the safety of the aircraft and its occupants. Such breaches can lead to serious incidents, including engine compartment fires, which were evidenced by an overseas incident involving the separation of a transducer cap. The potential civil or criminal penalties for not adhering to these safety directives are not explicitly stated in the provided text, but non-compliance with aviation safety regulations can generally result in severe penalties, including hefty fines and potential criminal charges.
