Documenting in-flight and postflight discrepancies
One of the topics candidates miss most on the Private Pilot Airplane written test. It sits under Postflight Procedures (Task A) in the FAA standards, code PA.XII.A.K2.
What this topic actually is
Anything that breaks, acts up, or looks wrong in flight is a discrepancy, and it belongs to the aircraft's records, not to you. The next person to fly that airplane needs to know, and so does maintenance.
The exam links this to airworthiness. You may not simply decide an item is fine and fly on; inoperative equipment is handled under specific rules (14 CFR 91.213), and only maintenance defers or clears items. Your job is to record the discrepancy accurately so the airplane's status is honest.
Why most candidates miss it
New pilots think a squawk is a personal note, so they log it in their own logbook or shrug it off if they are done flying. Airworthiness travels with the airplane, and the record has to reflect that. The trap that catches people: getting the rule slightly wrong. Try it yourself.
You notice an inoperative landing light after a night flight. What is the correct postflight action?
How to master it
Adopt one habit: any discrepancy goes into the aircraft record, immediately and factually. Deferring or placarding is a maintenance action under 91.213, not a pilot judgment call.
Then lock it in with repetition. The Private Pilot written test practice on Aviator IQ is built from the same FAA handbooks and figures, and every answer cites its source.
Discrepancies belong to the aircraft's records, not your logbook, and only maintenance defers them.
