Fuel Spill in Cargo Compartment?

[thurberm]

Anyone ever had this happen, either from a Benson tank, internal aux tank, or other source?

Fuel under the floor and leaking out the belly of the aircraft from under the cargo compartment, front to back.

What's the inspection protocol?  Is there one?

Any knowledge appreciated.

I remember a plane IFE'd back to Rhein Main shortly after take off that had fuel leaking out of a power unit it was carrying (-60 I think). They had the fire dept rinse it out, had AGE look at the power unit and drain the fuel and they left again.

I'd be curious as to how much fuel would really get to the underfloor area and eventually the flapper valves given the floor panels, D-rings etc are all sealed during installation.  Even with the use of Av-DEC tape, there is a requirement for a fillet seal on the floor panels.  Different story on J models though, especially if equipped with ECHS (roller conveyor storage in the floor), then fuel or any liquid for that matter will fill the underfloor structure.

We had people sitting there watching fuel pouring onto the pavement under the airplane.  It was significant.

I would say you need to pull the floor boards, depuddle and ventilate until you have the fuel cleared out.

If you want to make the decision easy all you need to do is remember the underfloor heat system pumps out bleedair straight from the manifold and if it cycles (IE overheats) that temperature is 180 degrees at the sensor...
