Dear all,
Sorry for baby english but i have a doubt about fai req. Could anyone please explaim the relation between detail part and assembly fai.

For instance our company is aileron manufacturer and our composite department has changed spar tooling.. We are assembly line and this spar can affect laser measurements..or form of aileron.. Or our datum holes are on spar for starting installatiion..

There is no change on spar dwg or part number only spar production method has changed.. No form fit function change..

Do we have to submit a full or partial fai to our customer for assebmly or only our composite department has to submit detail fai for spar..

Per which item of as9102 ?

Thanks for your help...

First step - do you have a copy of AS9102B?

Second - during contract review - what is the customer asking for?

Third - are you producing individual parts or are you producing many individuals parts that you will assemble into one piece?

based upon the answer - I could direct you into what to do.

In short - if you produce one piece - then that is all that you are required to do a FAIR - First Article Inspection Report.

Yes i have a copy.
I dont know the exact contract req.
Our company is producing many parts and those will become assemble as aileron eg riblets, spar, upper and lower panels.. Only spar producing tool was modified..
Do we have to submit partial fai for assembly or full fai for only spar..

Thanks

There are first articles and then there are AS9102 first articles. Is your customer/contract requiring actual 9102 first article forms?

By your answer - it appears that you have FAIR for every component ts that you make for this company contract.

It also appears that you made a change into tooling winch affects the DG&T - Geometric Dimension and Tolerance of the products.

Which means that you have to do a Delta or partial FAIR...

per AS9102B
4.6 Partial or Re-accomplishment of First Article Inspection
a. The FAI requirement, once invoked, shall continue to apply even after initial compliance.
b. The FAI requirements may be satisfied by a partial FAI that addresses only the changes from a baseline part number
provided all other characteristics were conforming on the previous FAI and are produced by the original production
processes.
c. When a partial FAI is performed, the organization shall, as a minimum, complete the affected fields in the FAI forms.
d. When the organization performs a partial FAI, the organization shall record the “Baseline Part Number”, including the
revision level and reason for the partial FAI on Form 1 (see field 14).
e. FAI requirements may be satisfied by a previously approved FAI performed on identical characteristics of similar parts
produced by identical means. When FAI requirements (partial or full) are satisfied in this manner, identify the “Baseline
Part Number” on Form 1 (see field 14).

f. The organization shall perform a full FAI or a partial FAI for affected characteristics, when any of the following occurs:
1. A change in the design characteristics affecting fit, form, or function of the part.
2. A change in manufacturing source(s), process(es), inspection method(s), location of manufacture, tooling, or
materials that can potentially affect fit, form, or function.
3. A change in numerical control program or translation to another media that can potentially affect fit, form, or function.
4. A natural or man-made event, which may adversely affect the manufacturing process.
5. An implementation of corrective action required to complete a previous FAI, as described in 4.4.
6. A lapse in production for two years shall require an update for any characteristics that may be impacted by the
inactivity. This lapse is from the completion of last production operation to the actual restart of production.
