Title: Chase YC-122 Avitruc

The YC-122 arose from USAF continued post-WW2 interest in cargo gliders. The Chase CG-14 was selected for further development and an enlarged all-metal variant was produced as the XCG-18. A powered version was also produced as the YC-122. The USAF lost interest in gliders but continued development of the YC-122. 18 examples were produced of several models using different engines and other minor variations.

The USAF then decided there was no future for small cargo aircraft and cancelled the project. The remaining aircraft were used as utility aircraft with one example later forming the basis of the Hiller X-18.

This title contains flight manuals for all variants of the YC-122. The files have been scanned from the original flight manuals and retain any colour pages.
