Overview
The Civil Aviation Regulations 1998, administered by the Civil Aviation Safety Authority, were enacted to ensure the safety of civil aviation in Australia. The legislative instrument F2006B04472 (Airworthiness Directives), specifically AD/BELL 206/17 Amendment 1, was introduced to address the issue of potential failure in the transmission mount spindle of Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series helicopters. The aim of this directive, which references Bell Service Bulletin No. 206-01-74-3 and Agusta Service Bulletin No. BT206-88, is to mandate inspections of the specified spindles within 25 hours time in service after 28 October 1974 to prevent any safety risks. This measure is in line with the overarching policy objective of the Civil Aviation Regulations 1998 to maintain and enhance the safety standards in civil aviation.
Scope and Application
The Civil Aviation Regulations 1998, specifically Part 39 - 105, governs the airworthiness directives for aircraft registered in Australia, and this particular regulation applies to the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 series helicopters. This legislation mandates that all model 206 and TH57A helicopters fitted with transmission mount spindles bearing the part numbers 206-031-554-1 or -3 must undergo an inspection within 25 hours of time in service following 28 October 1974. This requirement is to ensure compliance with safety standards, as outlined in Bell Service Bulletin No. 206-01-74-3 and its Agusta equivalent, Service Bulletin No. BT206-88. The scope of this directive is geographically limited to Australian jurisdiction, applying to all operators and owners of the specified helicopter models within the country. There are no stated exclusions or exemptions in this particular directive, and its application may be further refined or extended through subordinate instruments issued by the Civil Aviation Safety Authority (CASA).
Key Provisions
The Civil Aviation Regulations 1998, particularly in Part 39 - 105, detail specific requirements under the Civil Aviation Safety Authority's (CASA) Schedule of Airworthiness Directives. Section 11/74 pertains to the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, with the AD/BELL 206/17 Amendment 1 focusing on the inspection of transmission mount spindles. This directive applies to all model 206 and TH57A helicopters equipped with spindles with part numbers 206-031-554-1 or -3 (section 11/74). The applicable document for compliance is Bell Service Bulletin No. 206-01-74-3, with a corresponding Agusta Service Bulletin No. BT206-88 also referenced.
The primary requirement of section 11/74 is that an inspection of the transmission mount spindle must be conducted within 25 hours of time in service after 28 October 1974. This directive ensures that the specified components are examined for any wear, damage, or other issues that might compromise the safety and airworthiness of the helicopter. This is a critical step in maintaining the operational integrity of these aircraft.
Entities and individuals governed by these regulations, particularly operators of the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series helicopters, must ensure compliance with the inspection requirements outlined in section 11/74. This entails scheduling and performing the inspection as stipulated, using the referenced service bulletins as guidance. Failure to adhere to these requirements can result in the aircraft being deemed unairworthy, which could lead to grounding and potential legal ramifications.
In terms of consequences, section 11/74 does not specify a particular offence or penalty but underscores the importance of compliance to maintain airworthiness. However, general provisions within the Civil Aviation Regulations 1998 may apply, which could include civil or criminal penalties for non-compliance. Such penalties may include fines or imprisonment, depending on the severity of the breach and any resultant safety hazards. It is imperative for operators to follow these directives meticulously to avoid any adverse outcomes.
