Overview
The Civil Aviation Regulations 1998, enacted by the Australian Government and administered by the Civil Aviation Safety Authority (CASA), is a comprehensive piece of legislation that governs civil aviation safety in Australia. One of the specific directives under Part 39, known as AD/CESSNA 150/30Amdt 1, addresses the critical issue of exhaust heat exchangers in certain Cessna 150, F150, 152, and F152 series aeroplanes. This directive was introduced to ensure that these aircraft meet essential safety standards, particularly concerning the exhaust systems manufactured by KMR Industries. The policy objective is to mitigate risks associated with faulty exhaust heat exchangers, which can compromise the structural integrity and operational safety of the aircraft. Compliance with these directives is mandatory and must be adhered to before further flight and at regular intervals thereafter to ensure ongoing airworthiness and safety of these aircraft types.
Scope and Application
The Civil Aviation Regulations 1998, specifically PART 39 - 105, pertains to the Civil Aviation Safety Authority’s Schedule of Airworthiness Directives, addressing the safety of specific aircraft models within Australian airspace. One such directive, AD/CESSNA 150/30 Amendment 1, targets Cessna 150, F150, 152 & F152 Series Aeroplanes, focusing on the exhaust heat exchanger. This directive applies to Cessna 152 models with specific serial numbers and A152 models equipped with a KMR Industries P/N 1-1000 exhaust system. Compliance with this directive is mandatory, requiring adherence to Cessna Service Letter No. SE 78-71, with actions to be completed before further flight after 22 January 1979, and subsequently at intervals not exceeding 50 hours of time in service until paragraph “B” of Cessna SL No. SE 78-71 is met. It is noteworthy that compliance with previous versions of this directive does not satisfy the requirements of this amendment. The directive's reach is limited to specific aircraft models and configurations within the specified serial number range, ensuring targeted safety enhancements for these aircraft.
Key Provisions
The primary sections of the Civil Aviation Regulations 1998, specifically in relation to the AD/CESSNA 150/30 Amendment 1 for the exhaust heat exchanger, focus on ensuring the airworthiness of certain Cessna 152 and A152 series aeroplanes. Section 39.105 of the Schedule of Airworthiness Directives mandates that specific models of the Cessna 152 and A152 series, which fall within certain serial number ranges and are equipped with a KMR Industries P/N 1-1000 exhaust system, must adhere to the actions outlined in Cessna Service Letter No. SE 78-71. This directive is intended to address issues with the exhaust heat exchanger to ensure continued safe operation of the aircraft.
The obligations imposed by this legislation are clear and specific. Owners and operators of the affected Cessna 152 and A152 series aeroplanes must ensure that the required actions, as detailed in Cessna Service Letter No. SE 78-71, are implemented. This includes performing the necessary modifications or inspections before any further flight after 22 January 1979 and then at intervals not exceeding 50 hours of time in service. It is imperative that these actions are completed to maintain the airworthiness of the aircraft.
Failure to comply with the requirements outlined in the Civil Aviation Regulations 1998 and the associated Airworthiness Directive can lead to serious consequences. Section 97 of the Civil Aviation Act 1988 provides that any person who contravenes the regulations may be subject to penalties. For operational breaches, the maximum penalty can include fines up to $222,200 for individuals and up to $1,111,000 for corporations. Additionally, a conviction for these offences can result in imprisonment for up to five years, highlighting the seriousness of non-compliance with airworthiness directives. Ensuring adherence to these regulations is critical to maintaining safety standards in civil aviation.
