What role is coded as 50?

• A. Build Up
• B. Teardown
• C. All
• D. Inspection

Answer: (B)

In ECMS, each maintenance action is tied to a specific numeric code to standardize logging and reporting of work performed. The code 50 is designated for the teardown action, representing the disassembly or removal phase of maintenance. That alignment is why this option is the correct one: it directly matches the system’s mapping for teardown. The other actions—building up, inspection, or a broad “all” category—have different codes, so they aren’t represented by 50.
