Indeed not. I saw a K21 having it's snapped tail boom repaired when I happened to visit Zulu Glasstek a few years back.
If the Viking mentioned by Tingger was well documented and the repair was done correctly then it was one of the easy ones. The hard ones are where close inspection reveals undocumented repairs, especially if they are in crucial areas. Suspect they are looking at as much of the internal surfaces as the external ones.
