AD/BELL 205/34 Amdt 2 - Emergency Exits - Modification and Inspection

Overview

The Civil Aviation Regulations 1998, enacted by the Australian Parliament, form a comprehensive framework for ensuring the safety of civil aviation in Australia. One aspect of these regulations is the issuance of Airworthiness Directives (ADs) to address specific safety concerns. The AD/BELL 205/34 Amendment 2, concerning Bell Helicopter Textron 205 Series helicopters, was introduced to address the need for modifications and inspections of emergency exits on all model 205 helicopters. This amendment was designed to enhance safety by ensuring that emergency exits are clearly marked and easily accessible, as well as by requiring regular inspections to verify the integrity and functionality of these critical systems. The policy objective behind these regulations is to mitigate the risks associated with inoperative or poorly maintained emergency exits, thereby protecting the lives of passengers and crew in the event of an emergency.

Scope and Application

The Civil Aviation Regulations 1998, as detailed in PART 39 - 105, apply to all model 205 helicopters within the Commonwealth of Australia, establishing stringent safety standards that these aircraft must adhere to. The legislation mandates specific modifications and inspections to ensure emergency exits are both accessible and clearly marked, which includes installing emergency exit decals and release handle covers, adding spacers, creating additional inspection holes, and painting emergency escape locking pins. Compliance with these requirements is critical, as non-conformance could lead to safety risks. The regulations require these modifications to be completed within 100 hours of service after 31 August 1984, and comprehensive inspections to be conducted every six months and annually, as per Bell T.B. 205-78-2. This Act applies to all entities operating model 205 helicopters in Australia, with the safety authority ensuring that these standards are met through regular audits and checks.

Key Provisions

The Civil Aviation Regulations 1998, specifically Part 39 - 105, details the requirements for maintaining the airworthiness of Bell Helicopter Textron 205 Series Helicopters under the Civil Aviation Safety Authority (CASA). The key operative sections in this context are those that address emergency exits, specifically AD/BELL 205/34 Amendment 2. This amendment mandates the installation of emergency exit decals and release handle covers, which must comply with Bell S.B. 205-75-6 Rev. A (Part 1 a). Additionally, it requires the installation of spacers to the interior and exterior emergency escape release handle covers as per Bell S.B. 205-77-9 (Part 1 b), and the provision of additional inspection holes in the left and right passenger door assemblies as per Bell S.B. 205-77-6 (Part 1 c). Part 1 d necessitates the addition of a painted strip around the cylinder part of each emergency escape locking pin using white or another suitable colour. Furthermore, Part 2 of the directive requires the performance of six-month and annual inspections of the crew doors emergency ejection system and the passenger/cargo doors emergency escape panels, in accordance with Bell T.B. 205-78-2. The obligations imposed by these sections on the parties or entities they govern are stringent and specific. Operators of Bell 205 helicopters must ensure that all modifications and installations are completed within 100 hours of time in service after 31 August 1984, unless these modifications have already been performed. Furthermore, the regulations mandate that inspections be carried out at the intervals specified in Bell T.B. 205-78-2 after 31 August 1984. The directive also allows for flexibility by permitting the inspection to be scheduled to coincide with the next scheduled inspection nearest to 28 February 1985. These obligations are critical to maintaining the safety and airworthiness of the aircraft. Failure to comply with the requirements set out in this directive can lead to severe consequences. Although specific penalties are not detailed within the directive itself, under the Civil Aviation Act 1988, non-compliance with CASA directives can result in both civil and criminal penalties. Civil penalties can include fines and enforcement actions, while criminal penalties may include imprisonment. The exact penalties would depend on the severity and impact of the non-compliance, as well as any resulting harm or risk to safety. Therefore, it is imperative that operators adhere strictly to the specified requirements to avoid any potential legal repercussions.
