FAI Reports

First Article Inspection Reports are carried out for newly introduced items or items that have been changed after an ECN (engineering change notice).

Items are checked to ensure they meet customer requirements and reports are available upon request.

If changes are made to products that have been subject to a first article inspection after a two year period, a new FAI Report is required.
