Chemical in a fuel system test?
Onceapilot - the chemical in question was
supposed to be a 'fuel analog' - something to use during testing that has similar qualities to jet fuel but without the flammability risk (we use something called "calibration fluid' when testing certain engine control components - similar density, lubricity, etc. to jet fuel but much lower flammability and hence much safer if something goes wrong). Not only was the stuff not a suitable fuel analog - it was actually fuel system destructive
. The good news is that little of it made it into the aircraft fuel system - the exposure (and hence damage) was mainly limited to specific parts of the AR system.
Scuttlebutt is that Boeing is going after the vendor that supplied the "mislabeled" stuff with a vengeance
