• 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.

After over 50 years of flying I had my first incident (accident) on Thursday. Landing at my home grass field, I thought I hit a runway light causing the gear to collapse. My first costly pilot error? On further investigating of the runway damage and the gear struts, the gear failed before I hit the runway light. Not a pilot error but a design error on my part. As a retired system engineer I am not sure what hurts worse - pilot or design error! Last year I replaced the bungee struts with Wag Aero spring struts. I was responsible for the design of the attachments. I turned some solid steel rods to fit the ends of the tube and connected them to the gear and the fuse with bolts. After fitting them, I forgot to remove them and weld the inserts into the tubes. The bolts pulled through the thin tubing causing the gear failure. The runway light did little damage, the belly landing caused a lot more damage.
