What action must be taken after completing the specified tests in A-28.12.2, A-28.12.3, and A-28.12.4?

The correct action to take after completing the specified tests in A-28.12.2, A-28.12.3, and A-28.12.4 is to document the results and findings of those tests. Documentation is crucial in technical and safety standards as it ensures that there is a record of compliance with testing procedures. It also allows for traceability in case further analysis or verification is needed in the future.

Retesting, modifying, or repeating procedures may not be necessary unless the tests indicate that there are deficiencies or issues that need to be addressed. The focus is on capturing accurate test results, which facilitates maintenance, safety evaluations, and any required regulatory compliance. Thus, documenting the test outcomes becomes an essential follow-up step to confirm that the tests were completed successfully and to provide a reference for future inspections or assessments.
