Bonded doubler repairs to composites, carbon or glass must be justified considering the failure case, i.e depending on the structure classification the component must be able to carry limit or ultimate loading without the repair. Does the same hold true for metal to metal repair?
I mean bonded...
Two questions really,
No. 1, CS-25 (yeah I’m in Euro Land) makes no mention of “Secondary Structure” but does refer (but not define)to “Primary Structure” Can anybody quote me the definition and origin of Primary and Secondary Structure which doesn’t come from the SRM? FAR regs would be...

Can anyone please give me an idea of how the typical large passenger aircraft is checked structurally? e.g. when the check is made (FC / FH) and what is done at this check.
As a first post in a very interesting forum, I would like to ask 3rd party repair engineers what they use as an ultimate static stress (tensile) when designing “scab patches” on the fuselage skin. I think using Ftu leads to an over dimensioned repair when you consider that the fuselage is...
