AD/CESSNA 185/4 - Tail Wheel Assembly

Overview

The Civil Aviation Regulations 1998, which were enacted by the Australian Parliament, are designed to ensure the safety and efficiency of civil aviation in Australia. This legislation establishes a framework for regulating various aspects of civil aviation, including the issuance of airworthiness directives to maintain and improve safety standards. One such directive, AD/CESSNA 185/4, applies to all models of Cessna 185 Series Aeroplanes and pertains to the tail wheel assembly. It requires compliance with specific action as outlined in Cessna Service Letter 62-73, within 500 hours of flight time after 1 March 1963. This directive was introduced to address specific safety concerns related to the tail wheel assembly of Cessna 185 Series Aeroplanes, aiming to ensure that these aircraft remain airworthy and safe for operation. The underlying policy objective is to maintain the highest standards of aviation safety through regulatory oversight and enforcement of necessary safety measures.

Scope and Application

The Civil Aviation Safety Authority Schedule of Airworthiness Directives, specifically AD/CESSNA 185/4 concerning the tail wheel assembly of Cessna 185 Series Aeroplanes, applies to all models of Cessna 185 aeroplanes. This regulation mandates compliance with Cessna Service Letter 62-73, which must be implemented within 500 hours of flight time following 1 March 1963. The directive is enforced under the Civil Aviation Regulations 1998, which are applicable across the Commonwealth of Australia, ensuring that all operators of Cessna 185 aeroplanes within Australian jurisdiction must adhere to the specified maintenance and safety requirements. This regulation does not explicitly mention exclusions or exemptions, and its application is broad, extending to all Cessna 185 aeroplanes operating within Australia, governed by the Civil Aviation Act 1988 and enforced by the Civil Aviation Safety Authority.

Key Provisions

The Civil Aviation Regulations 1998, under Part 39 - 105, outline specific safety directives for aircraft, including the Cessna 185 Series Aeroplanes. The particular Airworthiness Directive AD/CESSNA 185/4 pertains to the tail wheel assembly, which is applicable to all models of the Cessna 185 series (s. 1). The directive requires that the tail wheel assembly must be addressed in accordance with the Cessna Service Letter SL 62-73 (s. 2). The compliance with this directive must be achieved within 500 hours of flight time after 1 March 1963 (s. 3). Entities governed by these regulations, particularly those involved with the operation or maintenance of the Cessna 185 series aeroplanes, are required to ensure that the tail wheel assembly meets the specifications outlined in the Cessna Service Letter SL 62-73. This involves adherence to specific procedures and standards set forth by the Civil Aviation Safety Authority (CASA) to ensure the continued airworthiness of the aircraft. The directive places a clear responsibility on the operators and maintainers to inspect, repair, or replace the tail wheel assembly as necessary, ensuring that the aircraft remains compliant with safety standards and regulations. Failure to comply with these directives can result in serious consequences. The Civil Aviation Regulations 1998 impose penalties for non-compliance with airworthiness directives. These can include fines, suspension or revocation of air operator certificates, and potential criminal charges for serious breaches. The specific penalties for breaches of these directives are outlined in the Civil Aviation Act 1988 and can include substantial fines and imprisonment, depending on the severity of the non-compliance and its impact on aviation safety. Operators and maintainers must therefore take these directives seriously to avoid legal repercussions and ensure the safety of their operations.
