COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Cessna 206 Series Aeroplanes
AD/CESSNA 206/40 Fuel Selector Valve Safety Wire 5/85
Applicability: Model 206 with S/Nos. 206-0001 to U20606827 and P206-0001 to P20600647. 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 (Cth), under Part 39 - 105, incorporate airworthiness directives to ensure the safe operation of aircraft. Specifically, Airworthiness Directive (AD) AD/CESSNA 206/40 addresses a critical safety issue for Cessna 206 series aeroplanes, particularly those with serial numbers within the specified ranges. This legislation was enacted to address the problem of potential fuel selector valve failures, which could lead to loss of control and engine fuel starvation. The AD mandates the action of fitting safety wire to the roll pin of the fuel selector valve in accordance with Cessna SIL SE84-5, referencing FAA AD 85-02-07 for compliance. The directive aims to ensure compliance by the next maintenance release after 31 May 1985. This intervention by the Civil Aviation Safety Authority is intended to mitigate the risk of accidents arising from the migration of the roll pin, thereby enhancing the overall safety of civil aviation.
Scope and Application
The Civil Aviation Regulations 1998, specifically under Part 39 - 105 and the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to the Cessna 206 Series aeroplanes with specific serial numbers. The directive, AD/CESSNA 206/40, mandates that action must be taken in accordance with Cessna SIL SE84-5 for the specified models, which are identified by their serial numbers ranging from 206-0001 to U20606827 and P206-0001 to P20600647. The directive is designed to address the potential risk of loss of fuel selector control, which can lead to engine fuel starvation if the roll pin connecting the fuel selector rotor shaft to the yoke assembly migrates out of its location. To mitigate this risk, safety wire must be fitted to the roll pin to ensure positive retention. The requirement necessitates compliance prior to the issue of the next Maintenance Release after 31 May 1985. This directive is referenced in FAA AD 85-02-07, indicating a cross-jurisdictional effort in maintaining aviation safety standards. The regulation applies directly to the specified Cessna 206 models and mandates specific action to ensure compliance with safety protocols.
Key Provisions
The Civil Aviation Regulations 1998, specifically Part 39 – 105, detail the Civil Aviation Safety Authority (CASA) Schedule of Airworthiness Directives. This legislation includes directives such as AD/CESSNA 206/40, which pertains to the Cessna 206 series aeroplanes and their fuel selector valve safety wire (subsection 5/85). This directive applies to specific model numbers within the Cessna 206 series, namely those with serial numbers ranging from 206-0001 to U20606827 and P206-0001 to P20600647 (subsection 5/85). The requirement of this directive is for actions to be taken in accordance with Cessna SIL SE84-5 (subsection 5/85). It is noteworthy that the Federal Aviation Administration (FAA) issued an equivalent directive, AD 85-02-07 (subsection 5/85).
This Act imposes obligations on the relevant parties, particularly those operating Cessna 206 series aeroplanes. The directive mandates that the specified action, in line with Cessna SIL SE84-5, be completed before the issuance of the next Maintenance Release following 31 May 1985 (subsection 5/85). The directive aims to ensure that the fuel selector valve safety wire is correctly installed and maintained to prevent the loss of fuel selector control, which could lead to engine fuel starvation (subsection 5/85). This requirement is crucial to maintain the safety and airworthiness of the aircraft.
Breach of the provisions set out in this directive may result in serious safety implications, including the potential for engine failure due to fuel starvation. Although the specific penalties or consequences for non-compliance with this directive are not detailed in the text provided, it is reasonable to infer that failure to adhere to airworthiness directives can lead to severe regulatory action. This may include fines, enforcement actions by CASA, and potential grounding of the aircraft until compliance is achieved. The exact penalties and consequences would be determined by CASA, considering the severity and circumstances of the non-compliance.
