FAA Inspection Authorization Practice Test

How should an IA approach unapproved sources of data found during maintenance?

Do not use unapproved data; seek approval or revert to approved data before proceeding. Use unapproved data if it seems credible. Use unapproved data only for non-critical tasks. Note the data and proceed.

Correct Answer:

Do not use unapproved data; seek approval or revert to approved data before proceeding.

Explanation:

When performing maintenance, you must base all actions on data that is officially approved for use. Unapproved sources can contain outdated or incorrect information and may lead to nonconforming work or unsafe conditions, which the IA must avoid. If you encounter unapproved data, do not apply it or rely on it to make maintenance decisions. Seek formal approval to use that data from the appropriate authority (such as the manufacturer or regulatory body) or revert to the current, approved data (the manufacturer’s current maintenance data, service bulletins, service letters, airworthiness directives, etc.) before proceeding. Document the situation and ensure the task is completed using approved information so the airworthiness and compliance requirements remain intact.
