AD/HU 269/61 - Fuel Tank Sump Cap Attachment - Inspection

Overview

The Civil Aviation Regulations 1998, specifically within Part 39, contains a series of directives that aim to ensure the safety and airworthiness of aircraft in Australian airspace. One such directive, AD/HU 269/61, was introduced to address potential safety issues related to the fuel tank sump cap attachment in Schweizer (Hughes) 269 Series Helicopters. This directive was enacted to ensure that all models within this series comply with the specified inspection requirements to maintain operational safety. The Australian Government, through the Civil Aviation Safety Authority, established this policy to mandate inspections at particular intervals to prevent any possible failure or malfunction that could compromise the safety of the aircraft and its occupants. The directive requires compliance within 100 hours of time in service after 31 December 1977, with subsequent inspections mandated at intervals not exceeding 300 hours. This regulatory measure underscores the commitment to stringent safety standards and proactive maintenance protocols to mitigate risks associated with the specified component of these helicopters. The enactment of this regulation by the Australian Government reflects a clear policy objective of safeguarding air travel and operational integrity within the nation's aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105 concerning the Civil Aviation Safety Authority Schedule of Airworthiness Directives, applies to all Schweizer (Hughes) 269 Series Helicopters, regardless of the model. This regulatory framework mandates that compliance with Airworthiness Directive (AD) Hughes 269/61, which pertains to the inspection of the fuel tank sump cap attachment, must be achieved within 100 hours of time in service following 31 December 1977. Furthermore, the compliance interval extends to not more than 300 hours of time in service thereafter, as detailed in Hughes Service Information Notice (SIN) No. N-148. This regulation is applicable nationwide, ensuring a uniform standard across all states and territories in Australia, thereby maintaining safety and operational standards in the aviation industry. The legislation does not specify any exclusions or exemptions; however, its scope can be extended or further detailed through subordinate instruments, which might provide additional clarification or specific operational guidelines.

Key Provisions

The key provisions of the Civil Aviation Regulations 1998, specifically under Part 39 - 105, concern the airworthiness directives for Schweizer (Hughes) 269 Series Helicopters. One notable directive is AD/HU 269/61 (section 12/77), which pertains to the inspection of the fuel tank sump cap attachment. This directive applies to all models within the Schweizer (Hughes) 269 Series Helicopters fleet. The directive mandates that compliance must be achieved within 100 hours of time in service after 31 December 1977, and subsequently, at intervals not exceeding 300 hours of time in service. Operators of Schweizer (Hughes) 269 Series Helicopters are required to adhere to this directive to ensure the safety and airworthiness of their aircraft. Specifically, they must inspect the fuel tank sump cap attachment as stipulated in Hughes SIN No. N-148. This involves meticulous examination to identify any defects, wear, or damage that could compromise the structural integrity of the fuel tank system. Ensuring compliance involves documenting the inspection process, retaining records, and performing necessary repairs or replacements as determined by the inspection. Failure to comply with the provisions of AD/HU 269/61 may result in significant legal consequences. The Civil Aviation Safety Authority (CASA) has the authority to enforce the regulations, and non-compliance can lead to penalties. The nature and severity of these penalties depend on the extent and impact of the non-compliance. In severe cases, non-compliance with airworthiness directives can lead to grounding of the aircraft, suspension of operations, and potential prosecution under civil or criminal law. The specific penalties are not detailed in the text but are generally severe, reflecting the critical nature of air safety regulations.
