What A Week - New P-38 Lightning, P-40 Warhawk, P-47 Thunderbolt, C-45 Twin Beech, and AT-9 Jeep Manuals Added to AirCorps Library!!

It's hard to choose a favorite out of the 70 new manuals that have been added this week, but when pressed, my pick of the day comes from the P-38 information, and is called "P-38 Production Illustrations". While this link will take you to a "manual", it is essentially just a collection of perspective view engineering drawings! The images below are just a few out of the 131 drawings contained in this manual - check it out!

AT-9 Jeep Manuals:

The Jeep is not the most well known out of the WWII era aircraft, but that's also what makes it fun to find manuals for it! Manufactured by Curtiss-Wright and used as a multi-engine trainer, less than 500 AT-9's were manufactured. CLICK HERE to view our small (but growing) collection of AT-9 manuals.

Pilot's Flight Operating Instructions for AT-9A, T.O. No. 0125KB-1, 5-June-1943

  

C-45 Expeditor / AT-11 Kansan / Twin Beech / Model 18 Manuals:

The C-45 Expeditor was the military version of the Twin Beech, or Model 18, while the trainer version, the AT-11 Kansan was used as a gunnery training aircraft stateside. One of the things that I love about the Twin Beech is how many names it had! It's not often that you can use 4 different options to describe essentially the same aircraft!

Service and Maintenance Instructions for C-45B, C-45F, JRB-3 and JRB-4, AN 01-90CD-2, 4-Nov-1947 Pilot's Handbook for RC-45J and UC-45J, NAVWEPS 01-90CE-1, 1-Jan-1954

P-38 Lightning Manuals:

Many of these P-38 documents are actually "Short Tech Orders" rather than traditional "manuals". What's the difference you ask? Short Tech Orders can be described as essentially service bulletins, and are short documents describing a very specific maintenance or operation topics. Manuals on the other hand, are larger documents such as parts catalogs, pilots handbooks, and structural repair instructions. There can be confusion because both manuals AND short tech orders can be identified by T.O. (Tech Order) document numbers. Even though they can be identified by the same letter distinction, the content is much different, and so is the look/formatting of these documents. The image on the left below is the cover a typical military manual, and the image to the right is a first page of a typical short tech order - pretty easy to tell them apart. For more on the Tech Order system, which was used to organize military published documents check out my blog post titled "The T.O. System".

P-40 Warhawk Manuals:

I think that the P-40 is the most recognizable warbird out there. Even people who know absolutely nothing about WWII or warbirds can recognize the shark mouth on the P-40 and say "that's such a cool airplane!" The shark mouth has been used for countless marketing projects over the last 75 years, and has become synonymous with "bad ass pilots". My coworker who manages our art department here at AirCorps Aviation, has even written his own blog post about the shark mouth - "The Good, the Bad, the Ugly: Aircraft Mouth Nose Art". While these P-40 manuals are much less interesting to the general public, for those in the know, they are pure gold, and we couldn't keep these aircraft flying without them!

P-47 Thunderbolt Manuals: 

If you don't know anything out AirCorps Aviation, the parent company of AirCorps Library, and you are a lover of the P-47, then you are most definitely missing out! We are in the final stages of completing a restoration of a P-47D-23RE Thunderbolt. There are less than 10 airworthy P-47's in the world, and when finished, ours will be unique among them. The majority of the flying P-47's are the later model that sports the bubble canopy, and ours is the earlier razorback configuration with a birdcage canopy. P-47's were manufactured by Republic Aviation, with a small number also manufactured by Curtiss during WWII. There are less than 5 razorback P-47's and all of them flying are examples of Curtiss manufactured birds - ours will be the only example of a Republic manufactured P-47! Click here to check out the project page and look though what is almost too much information and pictures about the project! Because of this project, you can imagine how excited we are when we get new P-47 manuals.
