AD/CESSNA 185/5 - Inertia Reel

Overview

The Civil Aviation Regulations 1998 were enacted to provide a comprehensive regulatory framework for civil aviation safety in Australia, addressing the need for standardised safety measures across the industry. One such legislative instrument, F2006B05141, pertains to the Cessna 185 Series Aeroplanes and specifically mandates modifications to the pilot's safety harness. This was introduced to address safety concerns related to the pilot's harness in agricultural category Cessna 185 Series Aeroplanes, ensuring that the harness is securely attached to the aircraft structure through an inertia reel. This requirement is outlined in Airworthiness Directive AD/CESSNA 185/5, which was issued to enhance the safety of pilots operating these aircraft by mitigating risks associated with harness detachment. The directive is an acceptable means of compliance with the installation specified in Rex Aviation Drawing Nos. RA375, RA375-1, and RA375-2, and compliance must be achieved before 30 June 1963. This legislative measure underscores the commitment of the Civil Aviation Safety Authority to maintain the highest safety standards in the aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, specifically PART 39 - 105 under the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives, governs the airworthiness of Cessna 185 Series Aeroplanes, particularly focusing on the AD/CESSNA 185/5 Inertia Reel directive. This legislation applies to all models within the agricultural category of Cessna 185 Series aeroplanes, mandating that the pilot’s safety harness must be modified by attaching the shoulder straps to the aircraft structure through an inertia reel. The installation as per Rex Aviation Drawing Nos. RA375, RA375-1, and RA375-2 is recognised as an acceptable means of compliance with this directive. The requirement to comply with this safety directive must be met before 30 June 1963. This regulation extends across the Commonwealth of Australia, ensuring that all relevant operators and entities within the scope of these aircraft adhere to the stipulated safety modifications.

Key Provisions

The Civil Aviation Regulations 1998, specifically in Part 39 - 105 under the Civil Aviation Safety Authority Schedule of Airworthiness Directives, contain provisions regarding the modification of the pilot’s safety harness for Cessna 185 Series Aeroplanes. Section AD/CESSNA 185/5 mandates that the pilot's safety harness must be modified by attaching the shoulder straps to the aircraft structure through an inertia reel. This requirement applies to all models in the agricultural category of Cessna 185 Series Aeroplanes (section AD/CESSNA 185/5). The installation must adhere to the specifications provided in Rex Aviation Drawing Nos. RA375, RA375-1, and RA375-2, which are recognised as acceptable means of compliance with these regulations (section AD/CESSNA 185/5). The compliance deadline for these modifications is set before 30 June 1963. The obligations under this legislation impose specific duties on the operators and owners of Cessna 185 Series Aeroplanes in the agricultural category. These parties must ensure that the modifications to the pilot’s safety harness are carried out correctly and in accordance with the provided drawings. Failure to adhere to these specifications could result in the aircraft not meeting the required airworthiness standards, potentially leading to non-compliance with the Civil Aviation Regulations. Operators and owners must therefore take proactive steps to ensure that the modifications are made by qualified personnel and that the aircraft is thoroughly inspected post-modification to confirm compliance. Breaching the provisions of these regulations can lead to significant legal and financial consequences. If an operator or owner fails to comply with the modifications specified in section AD/CESSNA 185/5, they may be subject to enforcement actions by the Civil Aviation Safety Authority. The penalties for non-compliance can include fines and potential grounding of the aircraft until the required modifications are made. The exact penalties may vary depending on the severity of the breach and any subsequent impact on flight safety, but operators should be aware that non-compliance can lead to serious repercussions. Ensuring timely and correct modifications to the pilot’s safety harness is, therefore, critical to avoid these potential consequences.
