• The Biplane Forum is a large global active community of biplane builders, owners and pilots. From Pitts to Skybolts, to older barnstormers, all types are welcome. In addition to our active community, our content boasts exhaustive technical information which is often sought after for projects and maintenance. This information has accumulated over the 12+ years the forum has been in existence.

    The Biplane Forum is a private community. Subscriptions are only $49.99/year or $6.99/month to gain access to this great community and unmatched source of information not found anywhere else on the web. We are also a great resource for non biplane users, since many GA aircraft are built the same way (fabric and tube construction). Annual membership also comes with two BiplaneForum.com decals.

We had a nasty surprise during this condition inspection, we found a broken longeron right in front of the right front spar attach bracket and front seat. Broken clean through.

On Friday, I had a lengthy discussion with my welder and A&P, both of them agree that to their knowledge, the proper fix is to cut out the cluster and weld in new tubing with an insert and fishmouth patch, in essence, making that area three layers. But the welder also says that there might be a newer school of thought and approved method of fixing this kind of break that he's not aware of.

To that end, I'm reaching out here to see if anyone that has experienced this kind of break has an alternative method of repairing that works.
