What this means for your checkride

To be airworthy an airplane needs its required inspections current. An annual inspection is required every 12 calendar months; an airplane operated for hire or used to give flight instruction for hire also needs a 100-hour inspection. The transponder has a 24-calendar-month check, and for IFR the pitot-static and altimeter system do too.

Flying an out-of-inspection airplane is a common violation, so the FAA tests the inspection intervals and which apply to a given operation.

The common trap

Pilots think the 100-hour can be exceeded freely. It may be exceeded by up to 10 hours only to reach a place for the inspection, and the overage comes off the next interval; the annual cannot be exceeded at all.

Before your checkride (14 CFR 61.39)

A code on your test report is an area of deficiency. An authorized instructor must review it with you and endorse that review before you take the practical test, and the examiner may revisit it during the oral. Study it until you can explain it out loud, not just recognize the answer.
