Keith,
I think he means the top of the head of the bolt rubbing against the fabric on the fuselage underneath it, not on the fabric of the horizontal stabiliser. I did wonder as well when I first got mine, as it seemed a prime spot for wearing through, but I had to take the tail off last year and found no indication of any wear at all. So I guess it's a case of "if it ain't broke, don't fix it". |
