AerSafe, a fuel tank ignition mitigation means developed by AerSale®, is one of the few Federal Aviation Administration (FAA) approved options currently available that complies with the Fuel Tank Flammability Reduction (FTFR) rule. The FTFR rule requires fuel tank ignition sources and flammability exposure to be reduced in fuel tanks that are most at risk.
Operators of Airbus 319, 320, 321 and Boeing 767 and 737 aircraft have two options: a flammability reduction means such as nitrogen inerting or an ignition mitigation means such as AerSafe. All affected passenger aircraft flying within or into the United States and operating under FAR Part 121 must be manufactured or retrofitted to meet the FTFR rule to avoid being grounded.
The AerSafe system limits the amount of available oxygen that can ignite fuel vapors and prevents sparks from initiating an explosion. It has been tested and developed to exact tolerances to fill the cavity of the Airbus A319, A320 and A321 series and Boeing 767, 737 NG, and 737 Classic series center fuel tank. AerSafe comes as a complete prefabricated kit, and after initial installation, the system is virtually maintenance-free. AerSafe provides an economical solution with no mechanical parts that can fail, time-change components to replace, or flight test requirements after installation. AerSafe also complies with the Notice of Proposed Rulemaking (NPRM) No. FAA-2016-6139.
Unlike nitrogen generating systems, AerSafe does not use an Air Separator Module (ASM), whose membrane fibers are damaged by high levels of ozone, therefore requiring ongoing service.
AerSale can perform AerSafe installation at any hangar around the world and can also provide training for the installation. Installation can be done at the same time as a light maintenance check or overnight after the aircraft center tank is de-fueled. AerSafe does not require maintenance between heavy check visits or special tooling to remove and install the parts. Aircraft can be modified or de-modified without any structural changes.
AerSafe Installation Kit includes:
All affected passenger aircraft operating under 14 CFR Parts 121, 125, and 129 must be manufactured or retrofitted to meet the FTFR rule. The FTFR rule is detailed in the FAA Advisory Circular 120-98A.
