FAR 25.981 & FTFR RULE AIRCRAFT FLAMMABILITY COMPLIANCE

Aircraft Fuel tank explosions occur in the ullage -- the space above the fuel level that can create a dangerous mixture of fuel and air. When an ignition source is present, perhaps a spark, the vapor adjacent to the spark ignites rapidly which creates a chain reaction that leads to a fuel tank explosion in milliseconds. 

​

Jetaire’s INVICTA utilizes a proprietary Reticulated Polyurethane Foam (RPF) that reduces the incidence of explosions. The foam is a lightweight, self-extinguishing, three-dimensional skeletal matrix that suppresses fuel ignition caused by heated fuel vapor, tank rupture, lightning strike, static discharge, or outside factors.
