Periodically, we have presented reports from Chuck Cravens detailing the restoration of an ultra-rare Beechcraft AT-10 Wichita WWII advanced, multi-engine trainer. As mentioned in previous articles, the project belongs to the Cadet Air Corps Museum and comprises the remains of several airframes, but is primarily focused upon Wichita 41-27322. The restoration is taking place at world-renowned AirCorps Aviation in Bemidji, Minnesota, and here is their latest update on progress with the Wichita as it stands presently….

Over the past few months, most of the work on the AT-10 involved the cockpit section, the main fuselage, and the vertical fin. Indeed a major milestone saw the cockpit section mounted to the main fuselage!

Cockpit

The cockpit interior looks great after painting. The dark green is an unusual color, but was matched exactly to a protected color sample from the original cockpit. (image via AirCorps Aviation)

Fuselage

Work on the fuselage included attaching handholds and footsteps. Once that was completed, the restoration team prepared the two main fuselage sections for mating together.

Vertical Fin

Project manager Aaron Prince finished the vertical fin’s internal structure. After completing this task, he had to cut and shape the skins so that they conformed to the fin’s structure; the compound curvature near the top of the rudder was especially challenging.

Want to get involved?

AirCorps Aviation is constantly looking for new technical material related to the AT-10. Due to the rarity of this aircraft, and the relatively low number produced, acquiring engineering drawings, parts catalogs, maintenance manuals, and other documentation has been much more difficult than with our past restorations. If you have any AT-10 material or know someone who does, the team would love to hear from you!
