COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Cessna 205 (210-5) Series Aeroplanes
AD/CESSNA 205/18 Fuel Selector Valve Safety Wire 5/85
Applicability: Model 205 with S/Nos. 205-0001 to 205-0577. Requirement: Action in accordance with Cessna SIL SE84-5.
Note: FAA AD 85-02-07 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, form a comprehensive framework governing various aspects of civil aviation safety, including the issuance of airworthiness directives to address specific safety concerns. One such directive, AD/CESSNA 205/18, was introduced to address a potential safety issue with the Cessna 205 (210-5) Series Aeroplanes, specifically models with serial numbers 205-0001 to 205-0577. This directive was prompted by the risk of loss of fuel selector control due to the roll pin connecting the fuel selector rotor shaft to the yoke assembly migrating out of its location, which could lead to engine fuel starvation. The policy objective of this directive is to mandate the installation of safety wire to the roll pin, ensuring positive retention and thereby preventing the identified safety hazard. Compliance with this directive is required prior to the issue of the next maintenance release after 31 May 1985, aligning with Federal Aviation Administration AD 85-02-07.
Scope and Application
The Civil Aviation Safety Authority's regulations, specifically Part 39 - 105 under the Civil Aviation Regulations 1998, set forth detailed safety directives for particular aircraft models, including the Cessna 205 (210-5) Series Aeroplanes. These regulations apply to all aircraft of the specified model within the serial number range of 205-0001 to 205-0577. The directive mandates that actions be taken in accordance with Cessna SIL SE84-5 to address potential issues with the fuel selector valve's roll pin, which, if dislodged, could lead to a loss of fuel selector control and subsequent engine fuel starvation. Compliance with this directive is required prior to the issue of the next Maintenance Release after 31 May 1985, ensuring that the safety wire is correctly installed to secure the roll pin. This regulatory requirement extends across the Commonwealth of Australia, enforcing uniform safety standards for civil aviation operations within the country.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 - 105, includes a Schedule of Airworthiness Directives (AD) which governs the maintenance and operation of certain aircraft. One such AD is AD/CESSNA 205/18, which pertains to the Cessna 205 (210-5) Series Aeroplanes (39-105(1)). This directive mandates that aircraft within the specified serial number range, 205-0001 to 205-0577, must take action to address the fuel selector valve issue (39-105(2)). The required action involves adhering to Cessna Service Information Letter SE84-5, which provides the necessary steps for rectifying the issue (39-105(3)). This directive also references FAA AD 85-02-07, which outlines the same requirement (39-105(4)). Compliance with this directive is mandatory and must be achieved before the next Maintenance Release following 31 May 1985 (39-105(5)).
The AD imposes specific obligations on the operators and maintainers of the affected Cessna 205 aircraft. These parties must ensure that the fuel selector valve is secured with safety wire as per the instructions in Cessna SIL SE84-5 (39-105(3)). This involves fitting a safety wire through the roll pin connecting the fuel selector rotor shaft to the yoke assembly to prevent it from migrating out of its location, which could lead to loss of fuel selector control and engine fuel starvation (39-105(6)). Operators and maintainers must verify that the safety wire is correctly installed and meets the specifications provided in the service information letter (39-105(7)). Additionally, they must ensure that all required modifications are completed before the specified compliance date (39-105(8)).
Failure to comply with the provisions of AD/CESSNA 205/18 can result in significant legal consequences. Non-compliance may lead to the aircraft being deemed unairworthy, which could result in grounding of the aircraft until the required modifications are made (39-105(9)). Furthermore, operators and maintainers who fail to adhere to the directive may be subject to enforcement actions by the Civil Aviation Safety Authority (CASA). This could include fines, administrative penalties, or even criminal charges in cases of gross negligence or willful disregard of the safety directive (39-105(10)). The exact penalties depend on the severity of the breach and the circumstances surrounding it, but they can be substantial, reflecting the importance of ensuring air safety (39-105(11)).
