AD/CESSNA 336/6 - Front Seat Restraint Installations - Modification

Overview

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, contain an Airworthiness Directive issued by the Civil Aviation Safety Authority (CASA) to address safety concerns related to front seat restraint installations in Cessna 336 Series Aeroplanes. This directive, AD/CESSNA 336/6, was enacted to ensure the modification of each front seat restraint installation by fitting a safety harness in accordance with a scheme approved by the Secretary. The directive mandates compliance with this requirement before 1 September 1972, aiming to enhance the safety of aircraft operations by mitigating risks associated with inadequate front seat restraints. The enactment of this directive by CASA under the authority granted by the Civil Aviation Act 1988 seeks to establish and maintain a high standard of airworthiness for all aircraft operating within Australia. The policy objective is to protect the safety of passengers and crew by enforcing modifications that comply with approved safety standards, thus addressing a critical gap in ensuring the structural integrity and safety of front seat restraints in Cessna 336 Series Aeroplanes.

Scope and Application

The Civil Aviation Safety Authority (CASA) under the Civil Aviation Regulations 1998, specifically in Part 39 - 105, mandates the modification of front seat restraint installations for all Cessna 336 Series aeroplanes. This directive, AD/CESSNA 336/6, requires that each front seat restraint installation be modified by fitting a safety harness as approved by the Secretary. This requirement applies to all models of the Cessna 336 series, ensuring uniformity and safety across the fleet. The directive stipulates that these modifications must be completed before 1 September 1972, highlighting the urgency and importance of adhering to this safety standard. The scope of the legislation extends to all operators of Cessna 336 Series aeroplanes within the jurisdiction of the Commonwealth of Australia, ensuring that the safety measures are uniformly implemented across the country. The regulations do not specify any exclusions or exemptions, indicating that all affected aircraft must comply with the directive to maintain airworthiness.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, specifically detail the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. Within this section, AD/CESSNA 336/6 outlines the requirements for Cessna 336 Series Aeroplanes. Section 10/71 mandates that all models of Cessna 336 Series Aeroplanes must have their front seat restraint installations modified by fitting a safety harness, following a scheme approved by the Secretary. This modification must be completed before 1 September 1972 to ensure compliance. The obligations imposed by AD/CESSNA 336/6 are clear and require the operators of Cessna 336 Series Aeroplanes to undertake the specified modification to the front seat restraint installations. This involves installing a safety harness as per the approved scheme, ensuring that the aircraft meet the safety standards set by CASA. The directive is designed to enhance the safety of pilots by providing a secure restraint system during flight operations. Failure to comply with the requirements outlined in AD/CESSNA 336/6 can result in significant consequences. Civil Aviation Regulations 1998 impose strict penalties for non-compliance with airworthiness directives. Operators who do not adhere to the directive may face civil penalties, including fines and potential legal action. Additionally, the aircraft may be deemed unairworthy, leading to grounding until the required modifications are completed. These measures underscore the importance of timely compliance to ensure the safety of all flight operations.
