What is the difference between a deviation and a workaround in AMQS, and how are they documented?

• A. Deviation is an approved departure from standard; workaround is a temporary measure to restore operation; both documented with justification and time limits and tracked for permanent resolution.
• B. Deviation and workaround are the same; both require no documentation and no time limits.
• C. Deviation is a temporary fix; workaround is a permanent change to standards; both require no justification.
• D. Deviation is only for legal compliance; workaround is for safety; both are documented with cost analysis.

Answer: (A)

In AMQS, you manage non-conformities by using formal controls that keep safety and airworthiness intact while you deal with issues. Deviation and workaround are two distinct, but related, tools for handling situations where the standard procedures or data can’t be followed as written. Both are documented with justification and a time limit, and both are tracked to ensure a permanent, proper resolution later.

A deviation is an approved departure from the standard or approved data. It isn’t something you do casually—it requires authorization because you’re stepping away from the established rule. The purpose is to acknowledge that in a specific situation, you can operate under a defined alternative that keeps safety intact, with formal justification, risk assessment, and a plan for how and when you’ll return to the standard. Documentation details what was changed, why, who approved it, the duration of the deviation, and the actions to close it with a permanent solution.

A workaround is a temporary measure to restore operation or capability while a proper fix or standard-compliant solution is being prepared. It doesn’t change the standard itself; it provides a salvage path to keep operations going in the interim. It also requires justification, limits on its use, and a stated timeline or criteria for removal once the root cause is addressed, along with a plan to revert to standard procedures.

That combination—approval, justification, time limits, and tracking toward permanent resolution—is what makes option A the correct approach. The other statements blur or contradict these points: they either treat deviation and workaround as the same, deny necessary documentation or time limits, or assign incorrect purposes (temporary vs permanent) without proper control.
