Halon-free Hand Fire Extinguishers

The CAA have published Certification Memorandum (CM) UK-CM-CS-013 to provide guidance on the certification of the installation of Halon-free handheld fire extinguishers.

Design changes for the installation of Halon-free handheld extinguishers in compartments occupied by passengers or crew on CS-23, CS-25, CS-27 and CS-29 aircraft may be classified as Minor, provided that compliance with the guidance material contained within the CM Section 3.2 is demonstrated.

Application of the CM in Validation Projects:

• For new Validation Projects, where Minor Classification is appropriate, such Design Changes will be processed per the Implementation Procedures for Airworthiness (IPA) or Technical Implementation Procedures (TIP) as applicable.
• For Validation Projects currently in work with the CAA, where the principles of the CM guidance have been followed, delegation to the Certificating Authority (CA) may be considered. Otherwise, Validation by the UK CAA remains required. To further address this, a Temporary Amendment to the Safety Emphasis Items (SEI) List has been published.

Teh CAA will issue further guidance for the General Aviation community on this issue in due course.
