New on AirCorps Library for February 18, 2026
This week's new manuals will help keep you warm on those cold winter flights and get you safely back on the ground. We have added a total of 23 new documents for heaters, wheels, and struts.
There are 10 new manuals in the Heaters and Related Equipment Unit on AirCorps Library. The new manuals cover space heaters, defrosters, and air ram switches from manufacturers Stewart-Warner, Bendix, Ecliplse-Pioneer, and, for the first time on AirCorps Library, McQuay-Norris.
The seven new manuals added to our Wheels Unit includes overhaul manuals and parts catalogs for manufacturers Goodyear, B.F. Goodrich, Bendix, Bertea, and Interstate Engineering.
Lastly, we also added six new manauls to our Struts Unit. These manuals are for components from Cleveland Pneumatic, Menasco, Loud and Bendx. You can see all the new manuals in the tables below.
All of this week's new manuals come from the collection generously donated by Aero Trader Warbird Restoration and Maintenance in Chino, California.
These new manuals, along with the new B-25 Mitchell and starter and voltage regulator manuals, mean we have added nearly 70 new documents to AirCorps Library in February.
