Years ago Van’s tested several factory built RV’s for smoke
penetration of the firewall. I remember they were amazed how much smoke they
got thru what they thought were pretty tight electrical, cable and misc. fittings
in a ground simulation. They tightened up the obvious holes and used High Temp
Silicone and still had an unacceptable volume of smoke coming in.
Fire or even an oil leak might have smoke that could prevent
breathing long enough or obscure vision or be enough of a distraction (pick one
or more) to set up a fatal scenario. This could have been a factor in the
Watsonville crash.
