PLT377: Airworthiness Responsibilities

What code PLT377 covers, why the FAA tests it, and how to study Airworthiness Responsibilities before your checkride.

Updated September 2026 · Learning statement code · Pilot / Instructor

Official FAA learning statement

Recall regulations - airworthiness certificates / requirements / responsibilities 10

What this means for your checkride

No person may operate a civil aircraft unless it is in an airworthy condition. The pilot in command is responsible for determining whether the aircraft is in condition for safe flight and must discontinue the flight if unairworthy mechanical, electrical, or structural conditions occur. The aircraft must also carry an appropriate and current airworthiness certificate and an effective registration certificate.

The pilot in command, not just the mechanic or owner, carries the responsibility to verify airworthiness before and during each flight.

The common trap

A current inspection sign-off does not remove the pilot in command's duty to determine the aircraft is safe for that specific flight.

Where to study it

14 CFR Part 91, 91.7, Civil aircraft airworthiness; 91.203, Certifications required

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.
