AD/CESSNA 337/18 - Fifth Seat Restraint - Modification

Overview

The Civil Aviation Regulations 1998, specifically the AD/CESSNA 337/18, aims to address the safety concerns associated with the fifth (rear) seat in Cessna 337 Series aeroplanes, particularly the Model T337G. This regulation was enacted by the Commonwealth of Australia to ensure that the rear seat is securely attached to the cabin floor structure to prevent any movement or detachment during flight. This legislation was introduced to fill a critical gap in safety standards, ensuring that the fifth seat is appropriately modified to meet the stringent safety requirements set by the Civil Aviation Safety Authority. The policy objective behind this regulation is to enhance the overall safety of air travel by ensuring that all seats within the aircraft are firmly secured, thus minimising the risk of injury or fatality in the event of turbulence or other in-flight emergencies.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, pertains to the regulation of airworthiness directives and applies to all civil aircraft within Australia. The particular directive AD/CESSNA 337/18 focuses on Cessna 337 series aeroplanes, specifically Model T337G, mandating that the fifth (rear) seat must be securely attached to the cabin floor structure in compliance with an approved scheme, as stipulated by the Secretary. This directive applies to all operators of the specified aircraft model, ensuring that any modifications are conducted to meet the safety standards set forth by the Civil Aviation Safety Authority. The requirement necessitates compliance prior to the issuance of a Certificate of Airworthiness, underscoring the importance of adhering to these standards to maintain the safety and airworthiness of the aircraft. This directive applies nationally across the Commonwealth of Australia, reinforcing the uniform application of safety standards for civil aviation throughout the country.

Key Provisions

The Civil Aviation Regulations 1998, specifically under PART 39 - 105, mandate that all Model T337G Cessna 337 Series aeroplanes must adhere to the Airworthiness Directive AD/CESSNA 337/18 (Section 11/74). This directive stipulates that the fifth (rear) seat of the aircraft must be securely fastened to the cabin floor structure. The attachment must be in accordance with a scheme approved by the Secretary, as indicated in the legislative instrument (Section 11/74). An acceptable means of compliance is outlined in the modification to Rex Aviation Ltd. Drawing No. RA-C-1341. Compliance with these provisions is mandatory and must be achieved before a Certificate of Airworthiness is issued. This means that any aircraft owner or operator must ensure that the fifth seat is properly installed according to the approved scheme before the aircraft can be deemed airworthy and legally permitted to fly (Section 11/74). The requirement is clear and unambiguous, leaving no room for interpretation regarding the necessity and method of installation. Failure to comply with these regulations can lead to serious consequences. Under the Civil Aviation Regulations 1998, any breach of the airworthiness directives can result in civil penalties. The penalties for non-compliance can be significant, and the specific penalties will depend on the nature and severity of the breach. In addition to financial penalties, operators may face operational restrictions or even the grounding of the aircraft until the required modifications are made. The gravity of the consequences underscores the importance of adhering to these safety regulations. Furthermore, the potential for criminal charges exists if the breach is deemed to be wilful or negligent. The severity of criminal penalties can vary but may include substantial fines and imprisonment for those responsible for the oversight. The Civil Aviation Safety Authority (CASA) has the authority to enforce these regulations, and they take a stringent approach to ensure that all aircraft meet the required safety standards. Thus, it is imperative for aircraft owners and operators to ensure full compliance to avoid both civil and criminal repercussions.
