AD/BELL 206/82 - Centre Post Installation - Structural Attachment - Inspection and Modification

Overview

The Civil Aviation Regulations 1998, specifically within Part 39, were enacted by the Parliament of Australia to ensure the safe operation of civil aircraft within the country's airspace. These regulations were developed to address gaps in safety standards and to provide a comprehensive framework for the oversight of civil aviation activities. Among the various safety directives, AD/BELL 206/82 was introduced to tackle issues identified in Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series Helicopters, particularly concerning structural integrity. The policy objective is to enhance the safety of these aircraft by mandating inspections and modifications to address specific structural weaknesses, as identified by the manufacturer through periodic evaluations. This directive applies to certain serial numbers of model 206L and 206L-1 helicopters, ensuring that these aircraft meet the required safety standards before continued operation.

Scope and Application

The Civil Aviation Regulations 1998, specifically under PART 39 - 105 and the Civil Aviation Safety Authority's Schedule of Airworthiness Directives, mandate that all Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series helicopters with specific serial numbers be subject to particular structural inspection and modification directives. This regulation applies to all model 206L helicopters with serial numbers ranging from 45004 to 45153 and 46601 to 46617, as well as all model 206L-1 helicopters with serial numbers ranging from 45154 to 45299. The directive follows findings of cracks in the centre post structural attachment area as communicated by the manufacturer in Bell Technical Bulletin No. 206L-79-41. Compliance with these directives is mandatory and must adhere to the specified requirements outlined in the referenced document. This regulation is enforced within the jurisdictional reach of the Commonwealth of Australia, ensuring the safety and airworthiness of the specified helicopter models across the nation.

Key Provisions

The Civil Aviation Regulations 1998 (Part 39 - 105) outline specific airworthiness directives for certain helicopter models. For example, Airworthiness Directive (AD) concerning Bell Helicopter Textron Canada (BHTC) 206 and Agusta Bell 206 Series helicopters (AD/BELL 206/82) requires the inspection and modification of the centre post structural attachment (section 1). This directive applies to all model 206L helicopters with serial numbers (S/Nos.) ranging from 45004 to 45153 and 46601 to 46617, as well as model 206L-1 helicopters with S/Nos. from 45154 to 45299. Compliance with this directive is to be achieved as per the requirements detailed in Bell Technical Bulletin No. 206L-79-41 (section 2). Under this directive, the primary obligations for the operators of affected helicopters include conducting thorough inspections of the centre post structural attachment areas. The inspections should identify any cracks or structural weaknesses in this area. If any deficiencies are found, operators are required to follow the modification procedures outlined in the Bell Technical Bulletin No. 206L-79-41 to rectify the issues. This ensures that the affected helicopters maintain their airworthiness and comply with safety standards set by the Civil Aviation Safety Authority (CASA) (section 3). Failure to comply with this airworthiness directive can have serious legal and safety implications. The Civil Aviation Regulations 1998 impose penalties for non-compliance with airworthiness directives, which may include both civil and criminal consequences. While specific penalties are not detailed within the directive itself, under the broader regulations, penalties can include fines and potential grounding of the non-compliant aircraft. The exact penalties can vary based on the severity of the non-compliance and the circumstances surrounding the breach (section 4). Operators must, therefore, ensure strict adherence to the AD/BELL 206/82 to avoid these repercussions and maintain the safety and airworthiness of their helicopters.
