I went to a used book store and found a copy of Aviation Mechanics Simplified. It was published in 1943 and is all about fixing aircraft. It is akin to one of the Glenco maintaince pubs today.
Anyway several things struck me about this 58 year old book.
1. Just about all of the techniques it talks about in the book still apply to aircraft manufactured today. Jet Engines, Composites and Electronics are noticably absent.
2. A lot of the drawings are the same one that are used in the latest revisions of 43.13b or other maintaince manuals.
3. They showed pictures of the inside of a 'Modern' aircraft assembly building. If you didn't know what you where looking it, it could have been Boeing or Airbus zipping sections together, Not Curtis.
Oh here is another interesting thing. Earlier I put up a post asking what toys(tools) I should get for school. They have the apprentice tool list for new hires at American Airlines. Other then two tools that where shop made tools for their radio shop every one of them can still be easily found and would be used on anything comming out of Touluse or Renton/Everett
There really is nothing new in aviation....Just food for thought.
