Pa-28-151 struts

Mike,

Thanks for the advice. The engineer has suggested changing the seals and
valves. However, I am concerned with the fact that a new set can stick
relatively soon again. Oh well, we might then have to buy the Granville
Strut Seal.

Once again, thanks to all for the advice.

Jay, I live in England and this winter is turning out to be quite
warmish. So it's not the cold this time. In fact, she started sticking
last summer. But as mentioned, by jiggling it before taxying, or just
turning around bend on the way to the active, she would unstick. It
wasn't a real problem until just before Xmas. As I was getting in, a
friend jumped on. We are both biggish and I felt that strut give way. It
sunk more than normal.

The inspection has revealed that it practically lost all its nitrogen.
And now there is a tiny leak.

A friend of mine, an engineer for the UK PFA, something like your EAA,
had a look and reckons the o-rings have "gone". He suggests changing them
and the valve (!?). Hence, I will take it to my engineer but wanted to
read more about the thing.


Ahhhh. Now that you mention that one has gone flat, that puts a different
complexion on the discussion.

A common technique to extend the life of a leaking seal that really does
work is Granville Strut Seal. It is a bit of a chore to get the stuff
into the struts, but most report that it does work well and can extend the
life of leaking/sticking seals by several years. I actually used it to
seal up a NEW nose strut seal job.

It is relatively inexpensive, but then again so are a new set of seals and
labor. And yes, it is recommended that the valve cores are replaced, if
not the valve bodies too.

Good Luck,
Mike
