| Subject: | seeping header shutoff valve |
Hi Guys,
This past month an experimental burned up in a t-hangar in Davenport. The
suspected reason was a milk house heater setup that was running on and off
and that he had a leaking fuel system. The 182 in the adjoining hangar and
a boat in the other were both burned. The 182 was written off as totaled.
The fuselage exploded and the heat caused the beams above to sag a little.
Worst of it all was that he had no insurance. None!
Anyway, I realized my heater system was the same as his and my cockpit had
that familiar smell too, so I put my finger around the shutoff fittings and
it was damp. It's the automotive brass cone type with springs that keep it
tight for a year or two. This one was the second I'd replaced, so I went to
the hardware store and bought a ball valve type with a yellow handle
denoting the gas, oil and water compatibility. It took a little while to
drain the tank and get the fittings arranged to keep from re-plumbing
everything and using a piece of the shutoff without the handle. A slight
mod to the valve handle took care of the job.
If you're using one of these brass fitting, take a look at it! The ball
valve types are a much safer bet.

This week there's no smell and it's dry in there.
I'm flying again with great weather and looking forward to more.
Endorphins are up again.
Do fly safe,
