A 30 day inspection is due when the aircraft has not flown for how long?

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

Answer: (A)

When an aircraft sits idle, maintenance schedules include inspections at set intervals to catch issues that can develop during storage. The first checkpoint for inactivity is after thirty days. If the aircraft has not flown for a month, a thirty-day inspection is due to verify that systems are still serviceable, check for corrosion or fluid leaks, ensure lubrication hasn't degraded, and confirm overall readiness before the next flight. After thirty days, longer intervals like sixty or ninety days may trigger additional checks, but the initial due item is the thirty-day inspection. A period shorter than thirty days isn’t the threshold for this specific check, and sixty or ninety days would correspond to later, separate intervals.
