The Federal Aviation Administration (FAA) has issued a supplemental type certificate (STC) for installation of AerSale´s new AerSafe system on the Boeing 737 classic series aircraft in compliance with the fuel tank flammability reduction (FTFR), the administration said.
This new STC is in addition to the STC for the Boeing 737 NG series, approved by the FAA earlier this year.
AerSafe limits the amount of available oxygen that can ignite fuel vapors and prevent sparks from igniting an explosion. AerSafe comes as a prefabricated kit that can be installed at any hangar. After initial installation, the system requires no maintenance or expensive spare parts.
The FAA enacted the FTFR rule after the crash of TWA flight 800 off the coast of New York. Federal investigations revealed that the accident was the result of an explosion caused by a spark igniting fumes in the center fuel tank of the Boeing 747. The FTFR rule requires fuel tank ignition sources and flammability exposure to be reduced in aircraft most at risk.
