General and detailed information for Aeronca pilots, restorers, and enthusiasts.		  

Here a collection of approved 337s from the logbooks of individual Aeronca owners.  These 337s are presented as reference for completing your own 337.  In the case of an STC, a sample 337 is often provided to you as part of the STC kit.  However, in the case of field approvals, it can be quite useful to see how another owner completed their 337.

Do you have any 337s that you'd like to have posted here.  Please send them to me.
