Example Drawings for STC approval.

Example Drawings for STC approval.

Example Drawings for STC approval.

(OP)
I'm trying to create engineering drawings for a structural nose cone assembly on an aircraft.  All the parts are designed and I'm trying to represent the drawings to show how to fabricate and assemble these parts in the correct format.  Is there anywhere on the web I can look at example fabrication drawings, particularly sheet metal to use as a guideline to how they need to look?  Also I would like to know how installation drawings are represented.  The ultimate goal is to take these drawings and use them for multiple aircrafts and satisfy the FAA guidelines.

Thanks

I work DOD, so a lot of military standards follow ASME guidelines.  Does the FAA expect drawings conform to that?  There may be bits and pieces of examples I could find in the books.  But I have not seen where it shows aircraft drawing examples.  Not to say there's not one because we may not have every standard.

I'm curious if for example; do you tolerance a flat pattern on a sheet metal part?  And how do you show that formed and riveted on a installation?

RE: Example Drawings for STC approval.

the flat pattern is "only" there for the manufacturing guys to know how to cut the sheet to allow them to make the part, really it's information only.  the engineering definition is the finished formed part, which you modelled first in order to get the flat pattern (no?).

there are probably many design manuals on-line, i'd expect that some part of DoD has there own as well.  has your group produced drawings in the past ?  but there are some guidelines ...
1) you need to put in all the information necessary to produce the structure you want,
2) you might consider that someone'll be inspecting the assembly to see if it conforms,
3) you might consider that someone'll be making the assembly ... you can make it easier for them if you build up your assembly to help them to put it together.  most large OEMs have a planning department that does this, the difference between "as engineered" drawings and "as manufactured" drawings.

RE: Example Drawings for STC approval.

For the part drawings & sub assy drawings I'd think ASME drawings stds are probably appropriate.

It's only on the installation drawings I'd think you might stray a little from the norm toward unique FAA requirements but I don't know for sure.
