• 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.

So I've already related the story of my Starduster crash (er, forced landing). Anyway, it'll be some time before the plane is flying again, if indeed I'm the one who gets it flying again (though I'm beginning to warm to the idea, the more I look at the plane the more I think "it's not that bad.") So, two questions:

I shut the engine (O-290-G) down before touchdown. It must have stopped horizontal or close (as it normally does) before it hit because even though the plane nosed over and cartwheeled, the propeller is undamaged (though I haven't taken precise measurements). It also helped that where I hit was very soft, very tall grass over mud. Even the prop spinner is undamaged. What do I need to check to verify the engine (crankshaft) is OK? I know if it had been running when it hit, it would need a teardown. In this case, is checking runout on the crankshaft and/or prop flange enough? I have, or have access to, anything I need in the way of indicators, etc.

Assuming it's OK, what do I need to do to preserve it for a year or so? Once I get it home in a couple of weeks, I can remount the prop and run it. It was almost due for an oil change anyway, so I figured change the oil, add Camguard, and fog it? What's the procedure there?
