Federal Aviation Administration, DOT.


Notice of issuance of advisory circular.


This notice announces the issuance of Advisory Circular (AC) 20-144, Recommended Method for FAA Approval of Aircraft Fire Extinguishing System Components. This AC provides guidance on the various aspects that should be considered in the FAA approval process of fire extinguishing system components manufactured under a Production Certificate, components to be FAA approved under the Part Manufacturer Approval process, or design changes to components originally approved by either method. This AC does not constitute a regulation, however, it provides a method, but not the only method, for obtaining approval of aircraft fire extinguishing system components. This is intended to enhance the standardization of all FAA Aircraft Certification Offices and Manufacturing Inspection District Offices in the approval process of the critical components of an aircraft fire extinguishing system.
