The mod came off a letter that was dated 24 August 95 and refered to a
loose bush on the spar of G-KITS. Builders were advised to inspect the
bushes, re-install any loose ones (though non have been reported on this
list) and:-
'Even if the rearmost bush on the starboard wing spar is not loose, layup a
patch of 2 plies bid over the the bush flange and onto the surrounding spar
to retain the bush. Cover with peel ply. Open up a hole through the
glassfibre after cure.'
This has obviously been incorporated into your newer instructions. But, if
you cut the glass around the bush, how will it be retained? As this stbd
rear bush is not slid into a socket, it doesnt matter about the thickness of
2 plies over the rear face. I drilled through the socket hole, and can still
sleep at night ;-)
