EASA SIB 2009-39R1
Contaminated Halon 1211 (BCF) and 1301 (BTM) Supplies
Summary
EASA Safety Information Bulletin SIB No: 2009-39R1 addresses the issue of contaminated Halon 1211 (BCF) and Halon 1301 (BTM) supplies used in aircraft fire extinguishers and ground fire extinguishers at airports. The contamination was linked to falsified sample test reports by a supplier, affecting handheld fire extinguishers typically found in aircraft cabins and some engine/APU systems. Several related EASA Airworthiness Directives remain valid to remove affected handheld Halon 1211 extinguishers from service, but no directives have been issued for engine or APU systems.
What Changed
This bulletin updates the aviation community on the ongoing risk of contaminated Halon supplies due to falsified testing by a supplier identified in 2009. It reinforces the validity of several existing Airworthiness Directives requiring removal of contaminated handheld Halon 1211 extinguishers. The bulletin also highlights that no new Airworthiness Directives are necessary for engine or APU fire suppression systems at this time.
Why It Matters
Contaminated Halon can compromise the effectiveness of fire extinguishing systems, posing safety risks to aircraft operations and ground handling. Aviation operators, maintenance organizations, and compliance teams must be aware of the contamination risk to ensure fire extinguishers meet required standards. Proper verification of Halon purity is critical to maintain airworthiness and regulatory compliance, especially given the prohibition on new Halon production and reliance on recycled supplies.
What To Do
Organizations involved in manufacturing or overhauling aviation equipment using Halon must independently verify the purity of Halon supplies rather than relying solely on supplier documentation. They should consult equipment manufacturers for applicable standards and ensure compliance with existing Airworthiness Directives related to contaminated Halon 1211 extinguishers. No specific compliance deadlines are stated in this bulletin.
