Can aircraft engine spark plug holes that are stripped out be repaired with a heli coil? I'm pretty certain the spark-plug holes come from the factory with Heli-Coils, as the aluminum threads wouldn't hold up in service.

I believe this to be accurate as well......If I'm wrong, I'm in very good company.  Jim

The procedure is described in the O-200 maintenance manual. See this post and the two posts following. Roy

Although something might be preventing her from replying, who knows? Any way if my tank can be fixed with a heli coil, the price just went up.
