What does data integrity entail in TO 00-20-1?

• A. Completeness, accuracy, timeliness, legibility, and protection from unauthorized changes.
• B. It relates only to the physical storage medium used for records.
• C. It is achieved by encrypting all maintenance data and nothing else.
• D. It means records are never altered under any circumstances.

Answer: (A)

Data integrity in TO 00-20-1 means that maintenance records are complete, accurate, timely, legible, and protected from unauthorized changes. This ensures the information truly reflects what was done, when, and by whom, providing a trustworthy basis for continuing maintenance, safety decisions, and regulatory compliance. Completeness requires all required data fields be present; accuracy means the data correctly matches the work performed, the parts used, and any measurements; timeliness ensures entries are made promptly to reflect the current status; legibility means the information can be read and interpreted; protection from unauthorized changes is enforced through controls like access restrictions, audit trails, and proper change control to detect and prevent tampering. The other statements miss essential elements: focusing only on the physical storage ignores data quality; encryption alone doesn’t ensure completeness, timeliness, legibility, or change protection; and never altering records ignores legitimate updates and corrections that must be managed properly.
