FAA, SAE International Focus on Engine Fire Protection System Standards for Aerospace

June 18, 2018

Aerospace systems, subsystems, and components must continue to operate as intended when exposed to fire, rather than going up in flames and ceasing to work altogether. Fire and flammability testing  is an all-important prerequisite to airworthiness, and the focus of a new technical standards  committee that SAE International in Warrendale, Pennsylvania, is forming in response to a request from Federal Aviation Administration (FAA) officials in Washington.

SAE International’s new A-22 Fire Protection and Flammability Testing technical committee will develop industry standards for testing aerospace systems and components to assist with the design and certification of fire protection systems, officials say. The initial program of work includes the development of a suite of standards to assist with the update of FAA Advisory Circular AC 20-135, “Powerplant Installation and Propulsion System Component Fire Protection Test Methods, Standards, and Criteria.” The committee will also determine methods to calibrate and setup a new sonic burner as an optional replacement for existing fire test burners.

“We are pleased to be working with the FAA on the development of these important standards and appreciate the trust that the FAA has placed in SAE International to utilize industry standards as guidance material,” says David Alexander, director of aerospace standards for SAE International. “Our expert constituents, leaders, and aerospace standards team provide industry and government stakeholders with the confidence to entrust us with the development and maintenance of safety-critical test methods.”

The FAA Tech Center Fire Safety Branch has been tasked by the Transport Standards Branch (TSB) to develop burner performance standards for the next-generation fire test burner for powerplant fire testing. The new burner should be much easier to calibrate and provide more consistent results than current methods, and be readily available for industry use, FAA official say.

The technical committee will meet November 1‒2, 2018 in Atlantic City, New Jersey, following the FAA Fire Safety Systems meetings scheduled October 30‒31.
