CESSNA C-165 — Airworthiness Directives

This document is an Advisory Circular (AC) issued by the Federal Aviation Administration (FAA) that provides guidance on the selection, approval, and safe use of hand fire extinguishers in aircraft. It is particularly relevant for those responsible for the maintenance and operation of aircraft, including manufacturers, installers, and operators. The AC outlines the types of fire extinguishers that are suitable for use in aviation, the criteria for FAA approval, and the recommended practices for ensuring fire safety on board. It emphasizes the transition from traditional halon extinguishers to newer halocarbon agents that are less harmful to the environment, while also detailing the necessary testing and certification processes for these extinguishers.

• Hand fire extinguishers are required under 14 CFR §§ 23.851, 25.851, 29.851, and others.
• Halon 1211 is no longer produced; halocarbon agents are recommended as replacements.
• Extinguishers must meet U.S. - UL ratings for approval, with a minimum rating of 5B:C for halocarbon extinguishers.
• Training for crew members on the use of fire extinguishers is essential for effective fire fighting.
• Proper location and mounting of extinguishers are critical for safety in aircraft.
