  1. Immediately, below 50 feet
  2. After noting it for next month
  3. After the issue is corrected ✔

Why: A defect found during preflight can mean the system is not safe. Correct the problem before operating, even when the normal maintenance date has not arrived.

Huh, didn't know that: Unscheduled maintenance can include lubrication, repair, overhaul, replacement, or a required software update.
