Airframe/Structural Repair
Airframe/Structural Repair
(OP)
Hi All.
I am a systems man by trade, and wm now in an enviroment which requires certification of Airframe/Structural Repair.
It is an alien concept after many years of never having to go near it.
Does anyone know of a good book, guide etc for self study of Principles etc..
This would be a huge help.
Many thanks.

RE: Airframe/Structural Repair
There are many many books discussed on this forum. Read through some of the old posts and do a search (as well as take a look at the faqs).
For a starting place, take a look at the Flabel book, "practical stress analysis for aircraft design engineers".
Also spend some time reading through AC43.13.
Good luck to you!

Eh ? It has just became apparent that this is a U.S site.
I am assuming of course.
As a Licensed Aircraft Engineer you hold certification rights iaw Aircraft SRM and/or in my case a Boeing Approved Repair Scheme.
I just want a book that takes you back to basics but covers all aspects to refresh the old grey matter and catch up a bit before the signing begins...Thats all.
Then of course throw back in the air and see if it flies !
RE: Airframe/Structural Repair
Joking aside , which government entity are you working under. FAA, CAA, LBA. or other ?
Most but not all of the posters on this site work on American registered aircraft. Hence the responses you got.
The other question is are you working heavy or light aircraft? You could try the "Standard Aircraft Handbook for Mechanics and Technicians" for basics or AC-65.15A Airframe Handbook - FAA then if you need something more advanced Go to Peery or Flabel or Bruhn.
Good luck.

As for guidance, Boeing has many documents and training manuals on airframe repairs. In fact, my best recommendation would be to get sent to the Boeing Airframe Repair course which they offer (or at least use to) to liasion engineers at the airlines and authorized repair centers. It is a very good training course and its on the mark as it addresses real world repairs.
RE: Airframe/Structural Repair
You said that you were in systems engineering; typically in the US systems engineers do not do structural analysis and therefore would not be DERs or similarly authorized by your country's governing civil aviation authority.
RE: Airframe/Structural Repair
Actually if we want to get really technical, you need to specify tht Structural DERs perform structural analysis & cert, and Systems DERs perform systems analysis & cert.
Why must we assume that something illegal is about to happen. Can't this be a legitimate question from a professional colleague who has changed jobs, asking a group of professionals for some educational material to "get him up to speed." It is quite a difficult endeavor to switch from systems to structures and vise versa.
Probablly should have searched before posting, though.

Oh never mind...
RE: Airframe/Structural Repair
In addition, I recommend: Bruhn, Niu's books, Flabel, and depending how deep your getting possibly Broek's practical fracture mechanics book.
OEM Design and Repair Manuals are also excellent resources, however, they are harder to come across anymore.
If you are into something you are not comfortable or don't fully understand, consult with a co-worker who is familiar or contact the OEM for assistance.

If you are outside the scope of the repair, there are now two paths to go down. 1) The published repair will fix the problem but you have to make minor changes to the repair -- this can be considered MINOR and not require additional approvals IF your internal Major/Minor decision tree allows it 2) You are developing the repair based off of experience or published repairs but the changes are not minor or there is no existing data - if your internal Major/Minor decision tree determines this is a MAJOR repair FAA approval must be obtained. The appproval can come from a DER (8110-3), the OEM (8100-9 for Boeing or RAS for Airbus), SFAR36 if your company is designated or an FAA office.
The key is that MAJOR repairs cannot be performed without APPROVED data whereas MINOR repairs (or MINOR changes to APPROVED MAJOR REPAIR DATA)can be performed with accepted data. If your company has an engineering group that is allowed to write MINOR repair procedures, that is all that is required. Most companies usually require two signatures on their paperwork, but some allow a single signature for minor repairs. It all comes down to what your company's Repair Station Manual or General Maintanence Manual or whatever document you have to live by says. I know American Airlines lets Co-Op students write repairs and sign them, but they have to have a lead or manager signature as well.
