AS9102 FAI requirements - Inspecting with fixtures, templates

[sharis]

A question has come up in my company regarding using fixtures or templates on an FAI. This doesn't appear to be addressed in AS9102. Some of us think that since the drawing says to inspect using a fixture, the dimensions do not need to be measured and recorded. Others think that an FAI requires every dimension on the drawing to be measured and recorded. There is no allowance on the AS9102 form to list a dimension and then state that it meets the fixture, since AS9102 states that all variables data must have numeric results recorded. Has anyone run into this before?

This can fall under the context of a required "fit check". The way it should be addressed is the tooling and or fixturing had to be fabricated to a design requirement. Just treat these in the same way you would subcomponents and records the dimensions obtained to verify that the tooling/fixturing meet the design data.
For the part that you are checking to a tool or fixture you would then indicate if it complied with the tool/fixture and identify it as part of the data.

This is where tool proofing comes into play. It's fine to use a fixture, jig or tool, but those items need to be proven accurate before use as an inspection tool.
