The title of this old post intrigues me;
I bet a true Construction Manual and Shop Manual could be created, between the Bellanca-Champion Club library and NASM GMB collection, and the collections of some of our notable members.
Add pictures taken during rebuilds and comments from the owners and you could fill several volumes.
The Cruisair is now an orphan without an owner of the type certificate, so no one could object to this being done.
It would be an act of love, the number that could be sold is probably rather small....
Furthermore, a compilation of all the STC mods and field approvals would be a benefit to all owners now and in the future.
Enough info is 'out there' to rival or exceed the 'Assembly manual & Plans' of many home built planes. A person could build a complete aircraft from scratch.
Neil Lafrance has not sold many plans for his updated Culver Cadet STF (Steel tube fuselage). Today's kit built 51% rule planes are so much easier to build and most outperform the Cruisair at the top end. I would imagine that none of the cross country types are safer, or have a slower landing speed. I can't get interested in a plane that stalls above 60 MPH.
I had a book compilation of "Steam launch" an enthusiast magazine from the 1960s it is a little disjointed because of the magazine format, but has since become the bible of small steam launch enthusiasts. (I know, I know, so I have a wide ranging taste in engineering hobbies) My point is that the Compiled Cruisair Manual might end up being an open ended document that would be updated my the most recent interested person and kept as paper and forum format. As the forum (or this forum) builds up a supply of useful info, it would be added to the paper (or electronic) media.
