AD/FPE/9 - Portable Extinguisher Discharge Head Trigger

Overview

The Civil Aviation Regulations 1998, as amended by the Legislative instrument F2006B09968, address the issue of safety concerns related to the operation of cabin portable fire extinguishers in Australian civil aviation. Enacted by the Australian Parliament, this regulation aims to ensure the airworthiness and safety of aircraft by issuing specific directives related to the maintenance and operation of fire protection equipment. The policy objective is to mitigate risks associated with the malfunction of fire extinguishers, particularly focusing on the breakage of triggers, which can severely compromise the safety of passengers and crew during an emergency. The regulation mandates compliance with specific standards and actions to rectify identified safety issues, thereby enhancing the overall safety standards within the Australian civil aviation sector.

Scope and Application

The Civil Aviation Regulations 1998, specifically Part 39 - 107, pertains to airworthiness directives issued by the Civil Aviation Safety Authority (CASA) and applies to all Cabin Portable Fire Extinguishers Halon 1211 and Water Glycol manufactured by First Technology Fire and Safety Ltd, formerly known as Fire Fighting Enterprises (UK) Ltd). This legislation is enforced within the Commonwealth of Australia, setting forth the requirements for ensuring the safety of portable fire extinguishers used in aviation. The mandate outlined in AD/FPE/9 is focused on rectifying issues with broken triggers on portable fire extinguishers, which have been identified as a safety risk due to instances where the trigger broke when operated without lifting the safety catch. To address this, the legislation requires compliance with Fire Fighting Enterprises (UK) LTD Mandatory SB 26-108 and mandates that the new trigger be manufactured from a stronger material to prevent future occurrences. This directive extends its application to all affected extinguishers manufactured prior to 4 September 1993, ensuring that these safety measures are implemented to mitigate risks associated with the identified issue.

Key Provisions

The key provisions of AD/FPE/9, found within Part 39 of the Civil Aviation Regulations 1998, pertain specifically to fire protection equipment, namely portable fire extinguishers, manufactured by First Technology Fire and Safety Ltd (formerly Fire Fighting Enterprises (UK) Ltd). The directive mandates that all cabin portable fire extinguishers, including those containing Halon 1211 and Water Glycol, must be fitted with a new trigger that is manufactured from an improved and stronger material (Section 107). This action is required in accordance with the Fire Fighting Enterprises (UK) LTD Mandatory Service Bulletin 26-108, and references UK CAA AD 004-09-92 for further context. The primary obligation under this directive is for the operators and maintainers of the specified fire extinguishers to ensure that the triggers are replaced with those made from the stronger material. This is a crucial safety measure, as the directive notes several incidents where the original triggers broke due to attempts to operate the extinguisher without lifting the safety catch. Compliance with this directive must be achieved prior to 4 September 1993, as stated in the background note of the regulation. Failure to comply with the provisions of AD/FPE/9 may result in serious safety implications and potential regulatory action. The Civil Aviation Safety Authority (CASA) has the authority to take enforcement measures against entities that do not adhere to the mandated safety requirements. The specific consequences of non-compliance are not detailed in the directive itself, but they could include penalties or legal action under broader aviation safety laws, which might involve both civil and criminal penalties depending on the severity of the breach and its impact on safety.
