For how long should an old (completed) OPNAV 4790/52 be retained?

An old (completed) OPNAV 4790/52 should be retained for 30 days. This timeframe is established to ensure that necessary documentation is accessible for reference or audits, yet it balances the need for efficient record management. The OPNAV 4790/52 form is primarily used for documenting maintenance actions and discrepancies on naval aircraft and equipment, making it essential to maintain such records for a brief period after completion to address any potential follow-up actions or inquiries. After 30 days, the likelihood of needing that specific documentation decreases substantially, allowing for the deletion or archival of documents that no longer serve their immediate purpose.
