Understood.  But if you have an onboard fire, what's the issue with melted
fittings?  The engine and fuel will have already been cut-off?  Is it
possible or likely to have an onboard fire without already having fuel or
oil leaking (in other words, what's on fire?).

About two years ago I swapped almost all of my AL fittings for steel, though
I'm not convinced it added to safety.

I am aware of a IVP that crashed in NC about 10 years ago that was allegedly
the result of AL fittings on a turbocharger.  I've asked before on this list
and never gotten a response how that occurs.  If there's oil flowing through
that fitting, I don't see how it got anywhere near a melting point.  If
there's no oil going through the fitting, well, that seems to be a more
likely cause of a crash...

 Though no regulation, they melt at a temperature too low for the comfort
of some pilots during an Onboard Fire.
