Everyone should do this:   Get some high quality metal valve caps, the kind
with a rubber gasket at the bottom.  Aircraft Spruce  #2525.   Then if the
Schrader valve leaks, it won't give you a flat.   The plastic caps that come
with the tubes don't last very long.

Subject: [LML] Re: LNC2 Tires revisited

I went south to Saint Simons Island, Ga on Tuesday, 12/28/10. On Friday,
12/31/10, while preflighting I noticed that the right main tire was at 25
psi rather than the 70 psi that I had when I took off last time.

My prior flat was on the left main. The right main has been on and OK and
nitrogen filled for the last 8 to 12 months.

Before pulling the wheel, the mechanic, who just so happened to have a new
bag of them, suggested that I try changing the Schrader valve.

I changed the valve on Friday, 12/31/10. Today, after flying back to
Detroit, and 2 landings, the tire still has full pressure. I am so happy
that I didn't have to change the tire prematurely.

Although always suggested, I have never seen a Schrader valve go bad at mid
tire life. From now on, I will be carrying a couple of spare Schrader
valves, just in case.
