Since 1959 there have been 18 fuel tank explosions on transport category aircraft. The many causes include lightning, wiring defects and heating of fuel vapours in the center tank. Following the TWA800 accident, the FAA produced Special FAR 88 in 2001 and the Fuel Tank Flammability Reduction (FTFR) Rule in 2008 both of which mandated extensive safety improvements to fuel systems.
As 737 pilots we have seen the effects of this in changes to center tank pump design and operation, and the introduction of NGS.
In this video I will cover the background to these changes in more detail, the ensuing regulation and NGS in depth.
