AD/BELL 206/10 - Removal Of Landing Gear Spacers - Modification

Overview

The Civil Aviation Regulations 1998, as amended and administered by the Civil Aviation Safety Authority, constitute a fundamental legal framework governing civil aviation in Australia. A specific legislative instrument, F2006B04413, introduced an Airworthiness Directive (AD) targeting the Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, particularly those fitted with a float landing gear kit P/N 206-706-008, as referenced in Bell Service Letter No. 206A-78. The directive was enacted to address a critical safety issue concerning the removal of landing gear spacers, aiming to ensure that compliance with these modifications is achieved within 100 hours of time in service following 14 February 1969. This intervention underscores the Civil Aviation Safety Authority's commitment to maintaining stringent safety standards in the aviation sector, thereby mitigating potential risks associated with non-compliance.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 105, mandates the Civil Aviation Safety Authority (CASA) to issue airworthiness directives, including the one concerning Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters. This directive applies to all models of these helicopters that are fitted with float landing gear kit P/N 206-706-008. The directive requires the removal of landing gear spacers as a modification, with compliance expected within 100 hours of time in service after 14 February 1969, as documented in Bell Service Letter (SL) No. 206A-78. The regulation applies broadly to all operators and owners of the specified helicopter models, ensuring that any helicopter of this type that meets the specified criteria must comply with the directive to maintain airworthiness standards. The jurisdictional reach of this regulation is national, extending across all states and territories within the Commonwealth of Australia. There are no stated exclusions or exemptions in this specific directive, and compliance is mandatory for the safety and regulation of civil aviation within Australia. The scope of this directive is extended and clarified through subordinate instruments and CASA guidelines which provide further detail on compliance and enforcement mechanisms.

Key Provisions

The Civil Aviation Regulations 1998, specifically under Part 39 - 105, include the Civil Aviation Safety Authority's Schedule of Airworthiness Directives. One such directive pertains to Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, identified as AD/BELL 206/10. This directive mandates the removal of landing gear spacers and requires a modification to ensure compliance (s. 1). The applicability of this directive is confined to all models fitted with float landing gear kit P/N 206-706-008 as detailed in Bell Service Letter (SL) No. 206A-78 (s. 2). The primary requirement of this directive is that the compliance must be achieved within 100 hours of time in service after 14 February 1969 (s. 2). This timeframe is critical, as it ensures that the necessary modifications are made promptly to maintain the airworthiness of the helicopters involved. The directive specifies the need to remove the landing gear spacers and perform a modification, which is a direct action to enhance safety and operational standards. The obligations imposed by this directive on the parties or entities governed include ensuring that the modifications are carried out by certified personnel and that records of the compliance actions are maintained. Operators and owners of the affected helicopters must adhere to the directive by scheduling the required modifications within the stipulated period and ensuring that the helicopters are kept airworthy by complying with all technical and operational standards set forth in the directive (s. 3). Failure to comply with the directive can lead to serious safety risks and potential grounding of the affected aircraft. In terms of penalties and consequences for non-compliance, the Civil Aviation Regulations provide for both civil and criminal liabilities. Non-compliance with an Airworthiness Directive can result in significant civil penalties, including fines and potential suspension of the aircraft’s certificate of airworthiness. Criminal penalties may also apply, particularly if the non-compliance is found to have caused an accident or incident, leading to prosecution under the relevant aviation safety statutes. The maximum penalties can vary, but they are intended to be sufficiently stringent to ensure adherence to safety regulations (s. 4).
