Fuel Tank Ignition Mitigation System

Contact a Specialist

Easy-to-install, low-cost alternative to expensive OEM nitrogen inerting systems

Proven military technology for reliable, low-maintenance FTFR compliance

Introducing AerSafe, AerSale’s cost-saving solution to meet the FAA’s latest fuel tank flammability mitigation requirements

FTFR Background

The FAA’s published Fuel Tank Flammability Reduction Rule (FTFR) mandates that operators of transport category aircraft must take measures to mitigate the possibility of fuel tank vapor ignition in certain aircraft models. To avoid being grounded, all affected passenger aircraft flying within or into the United States under FAR Part 121 operations must be equipped with an FAA-approved fuel tank migration means to meet the FTFR mandate. Affected aircraft models include the Airbus 319, 320, and 321 and Boeing 777, 767 and 737.

AerSafe Development

(ref: FAA Advisory Circular 120-98A), OEMs offer nitrogen inerting systems for their aircraft; however, these systems are expensive to purchase and maintain. AerSale recognized the opportunity to develop an engineered solution to comply with FTFR requirements, and we are proud of our engineers and technicians who have successfully brought AerSafe to market as a safe, reliable, and low-cost FTFR means of compliance.

AerSafe works by installing nonmechanical, fuel tank-formed inserts that limit the amount of available oxygen that can potentially ignite fuel vapors. AerSafe incorporates a proven military anti-flammability technology, which we have configured to meet the fuel tank cavity tolerances of Airbus A319, A320, and A321 series and Boeing 777, 767, 757, 737 NG, 737 Classic series and 727 aircraft.

Benefits of AerSafe

Our AerSafe customers have already saved millions by avoiding the purchase of expensive OEM inerting systems to meet current FTFR requirements for their portfolio aircraft, and we invite you to speak with an AerSale representative about how AerSafe can also help save your organization time and money.
