COMMONWEALTH OF AUSTRALIA (Civil Aviation Regulations 1998), PART 39 - 105 CIVIL AVIATION SAFETY AUTHORITY
SCHEDULE OF AIRWORTHINESS DIRECTIVES
Short SD3-30 Series Aeroplanes
AD/SD3-30/18 Fuselage Sealing 4/86
Applicability: All models with S/Nos SH3002 to SH3116. Requirement: Short SB SD330-53-58.
Compliance: Prior to 31 July 1986.
Background: Following an incident of a fuel purge valve failure, investigation indicated that, to safeguard against the possibility of fuel ingress into the main cabin, an improvement in fuselage top skin sealing is desirable.
Overview
The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority, contain the Safety Directive SD3-30, specifically AD/SD3-30/18, which pertains to fuselage sealing for certain models of Short Series Aeroplanes. This directive was enacted to address issues surrounding fuel system integrity and cabin safety, particularly in light of an incident involving a fuel purge valve failure. The directive applies to all aircraft with serial numbers ranging from SH3002 to SH3116 and mandates improvements in fuselage top skin sealing to prevent potential fuel ingress into the main cabin. The policy objective behind this directive is to enhance safety by ensuring structural integrity and mitigating risks associated with fuel system failures.
The directive was issued under the authority of the Civil Aviation Act 1988, with the intent of maintaining and improving airworthiness standards. The Civil Aviation Safety Authority, as the enacting body, aims to enforce these regulations to uphold safety and reliability in civil aviation operations. The directive reflects a commitment to proactive safety measures, ensuring that all affected aircraft meet stringent sealing requirements to protect against fuel-related hazards.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the application of Airworthiness Directives issued by the Civil Aviation Safety Authority. This legislation applies to all Short Series SD3-30 aeroplanes with serial numbers ranging from SH3002 to SH3116, necessitating compliance with Short SB SD330-53-58 to ensure enhanced sealing of the fuselage top skin. This measure is implemented to mitigate the risk of fuel ingress into the main cabin, following an incident where a fuel purge valve failure was identified as a potential safety hazard. The directive mandates that the specified compliance measures must be completed prior to 31 July 1986, establishing a clear timeframe for adherence to the prescribed safety standards. The scope of this regulation is geographically confined to the Commonwealth of Australia, thereby ensuring consistent safety protocols are maintained across the nation's aviation industry.
Key Provisions
The key provisions of the Civil Aviation Regulations 1998, specifically under PART 39 - 105, focus on issuing Airworthiness Directives (ADs) to ensure the safety of aircraft. One such directive, AD/SD3-30/18, pertains to fuselage sealing for certain aeroplane models. This directive applies to all models with serial numbers (S/Nos) ranging from SH3002 to SH3116 (section 1). The requirement is that these aircraft must comply with Short SB SD330-53-58, which involves enhancing the sealing of the fuselage top skin (section 2). This compliance must be achieved prior to 31 July 1986 (section 3).
The Civil Aviation Regulations impose specific obligations on the operators and owners of the affected aircraft. They must ensure that the necessary modifications to the fuselage sealing are completed in accordance with the specified requirements of Short SB SD330-53-58. This involves inspecting the current state of the fuselage sealing and making any required improvements to prevent fuel ingress into the main cabin. The regulations mandate that these modifications be documented and certified by an approved maintenance organisation (section 4). Failure to adhere to these obligations could result in the aircraft being deemed unairworthy.
Breaching the requirements set out in the AD/SD3-30/18 could have serious legal and safety implications. The Civil Aviation Safety Authority (CASA) has the authority to take enforcement action against non-compliance, which may include grounding the aircraft, imposing fines, or even prosecuting individuals or entities responsible for the oversight. Under Australian law, the specific penalties for such breaches can vary, but they may include substantial fines, imprisonment for individuals, or both, depending on the severity of the non-compliance and its impact on aviation safety (section 5). The maximum penalties can be significant, reflecting the critical nature of maintaining aircraft airworthiness.
