There's a discussion on a ul ng about a guy that built a strut braced light
plane and in a fit of overkill (apparently ) decided to add a (non plans)
jury strut. He drilled a hole (3/16") on the bottom of the tubular alum
spar. Then realized he may have made a mistake. Whats the outcome and is
there a fix without putting in a new spar. Just curious (and I didn't do
it!!) Pat


Answer: There is a repair, but a DER structural engineer should review
the repair. The repair is to ream the hole to accept a bronze bushing
and maybe a doubler depending on the location, edge distance, and
material make up. This is no place to guess or just replace the spar.
