What should be included in documentation after fault repair?

• A. The fault location, repair performed, re-test results, and system integrity verification
• B. Only the date of repair
• C. A summary of occupant feedback
• D. The cost of parts used

Answer: (A)

After a fault repair, the documentation should capture where the fault occurred, what work was done to fix it, the results of post-repair testing, and evidence that the system’s integrity is intact. Recording the fault location provides a clear trace for future maintenance. Detailing the repair shows exactly what was changed or replaced. The re-test results demonstrate that the fault is actually resolved and that the system responds correctly under test conditions. The system integrity verification confirms no related issues and that overall reliability and safety standards are maintained. A repair date alone doesn’t prove functional restoration, occupant feedback isn’t a substitute for technical validation, and the cost of parts isn’t part of the essential verification.
