Without the Unit Engineering Officer's approval, how long can corrosion discrepancies remain open (except deployed aircraft)?

• A. 30 days
• B. 15 days
• C. 60 days
• D. 90 days

Answer: (A)

Corrosion is a condition that must be controlled quickly because it can spread and weaken the structure. When a corrosion discrepancy is found, it’s opened in the maintenance system and requires Unit Engineering Officer approval to extend the fix window. For aircraft that are not deployed, that discrepancy can remain open for up to thirty days without that approval. This timeframe is set to allow adequate time to assess the issue, plan the corrective action, and obtain the necessary approvals while preventing the corrosion from progressing. A shorter window would be too tight for proper planning, and longer windows would increase the risk to airworthiness. Deployed aircraft may have different rules, but the thirty-day limit applies to non-deployed cases.
