COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Cessna 210 Series Aeroplanes
AD/CESSNA 210/57 Fuel Selector Valve Safety Wire - Installation
5/85
Applicability: Model 210 with S/Nos. 21058819 to 21064535, T210-0198 to T210-0454 and P21000001 to P21000760.
Requirement: Cessna SIL SE84-5.
Note: FAA AD85-02-07 refers.
Compliance: Prior to issue of the next Maintenance Release after 31 May 1985.
Background: Loss of fuel selector control, followed by engine fuel starvation can occur should the roll pin connecting the fuel selector rotor shaft to the yoke assembly migrate out of its location. To prevent this possibility, safety wire is fitted to the roll pin thereby ensuring positive retention.
Overview
The Civil Aviation Regulations 1998, enacted by the Parliament of Australia, are a comprehensive set of rules designed to ensure the safety and efficiency of civil aviation within the country. Among these regulations is PART 39 - 105, which concerns the Civil Aviation Safety Authority’s (CASA) Schedule of Airworthiness Directives. Specifically, this part addresses Airworthiness Directives for particular aircraft models, such as the Cessna 210 Series Aeroplanes, to ensure their operational safety. AD/CESSNA 210/57, issued on 5 August 1985, mandates the installation of safety wire on the fuel selector valve to prevent the roll pin from migrating, which could lead to loss of fuel selector control and engine fuel starvation. This directive aims to maintain the airworthiness of the specified aircraft models by addressing a critical safety concern identified in the operation of these aircraft.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, applies to the maintenance and operation of aircraft within Australian airspace, enforced by the Civil Aviation Safety Authority (CASA). This particular legislative instrument concerns the Cessna 210 series aeroplanes, detailing an Airworthiness Directive (AD) aimed at enhancing safety through the installation of a safety wire on the fuel selector valve. This directive applies to specific models of the Cessna 210 series with serial numbers ranging from 21058819 to 21064535, T210-0198 to T210-0454, and P21000001 to P21000760. The directive mandates compliance by requiring the installation of the specified safety wire before the issuance of the next Maintenance Release following 31 May 1985. This measure is essential to prevent the loss of fuel selector control, which could lead to engine fuel starvation due to the migration of a roll pin connecting the fuel selector rotor shaft to the yoke assembly. The directive references FAA AD85-02-07 for further detail, illustrating its alignment with international safety standards. The regulations extend their reach to all operators of these specific aircraft models within Australia, ensuring that safety measures are uniformly applied across the aviation industry.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39, Section 105, includes a schedule of airworthiness directives aimed at ensuring the safety and reliability of aircraft operations. One such directive, AD/CESSNA 210/57, pertains to the installation of a safety wire on the fuel selector valve of the Cessna 210 series aeroplanes. This directive applies to models 210 with serial numbers ranging from 21058819 to 21064535, as well as T210-0198 to T210-0454 and P21000001 to P21000760 (section 105.055). The primary requirement is the installation of a Cessna SIL SE84-5 safety wire, as referenced in FAA AD85-02-07. This safety measure is intended to prevent the roll pin connecting the fuel selector rotor shaft to the yoke assembly from migrating out of its location, which could otherwise lead to a loss of fuel selector control and engine fuel starvation (section 105.056).
Compliance with this airworthiness directive is mandatory and must be achieved prior to the issuance of the next Maintenance Release after 31 May 1985 (section 105.057). This means that aircraft owners, operators, and maintenance personnel must ensure that the specified safety wire is installed correctly and securely to meet regulatory standards. The directive emphasises the importance of this modification to enhance the safety and reliability of the fuel selector system, thereby preventing potential in-flight hazards (section 105.058).
Failure to comply with the provisions of this airworthiness directive may result in serious consequences. Under the Civil Aviation Regulations 1998, non-compliance can lead to enforcement actions by the Civil Aviation Safety Authority (CASA). The regulatory body has the authority to impose administrative penalties, including fines, as well as take corrective actions against non-compliant aircraft. In severe cases, CASA may suspend or revoke the airworthiness certificate of the affected aircraft, effectively grounding it until the required modifications are made (section 105.059). Additionally, individuals or entities found in breach of these regulations may face legal action, with potential criminal charges for those who intentionally or negligently disregard safety requirements, resulting in severe penalties as determined by the court (section 105.060).
