REFLECTOR: MT leading edge tape damage

[Dave T Nelson]

To add to what I sent to the reflector...  there are (at least) two key
issues.  First... any damage to the stainless part of the leading edge must
be taken seriously *if it has caused delamination or loosening of the
stainless*... I had a major ouch to mine flying into the Oshkosh airshow
several years ago when a cowl screw departed the airframe... I went and
dragged the MT guy out of his booth to inspect it before flying home.
What he told me was that I needed to pay strict attention to the SS/leading
edge bonding - but that if the SSLE was secure, there shouldn't be a
problem.

The second issue is anything that would allow moisture ingress.  That is
strictly not allowed.

My suggestion would be to remove the tape... inspect and repair any damage
to the leading edge... and then replace the tape.

I'll try to make it out to the hangar tomorrow to check on the 3M PN of the
tape for you.  It's very high quality stuff.

The picture didn't come through originally due to TVBF size restrictions,
but it's not really in the stainless (which is just on the very edge), but
there is this additional tape-like material, which I think is for abrasion
resistance... I'm trying to decide how critical that is - can I just JB
Weld it, or should I remove the tape, repair the prop, and install new
tape.  Picture attached.

      Brett,
      If its the SS leading edge, then yes, repair with JB Weld.

            I found a couple of nicks in my MT prop on the leading edge
            tape (not
            actually the leading edge).  I'm tempts to just fix it with JB
            weld, but
            was wondering how important the tape is.  Should I have someone
            remove
            the tape, fill the nick, and replace the tape, or is JB Weld
            fine for
            this?
