Definition
The legally recognized condition of an aircraft as established by the FAA, indicating whether it conforms to its approved type design and is in a condition for safe operation. This status is documented through the airworthiness certificate issued under 14 CFR Part 21 and is maintained through compliance with applicable airworthiness directives, required inspections, and maintenance records.
Plain English
The FAA's formal recognition that an aircraft is legally and physically fit to fly. It is established by paperwork (the airworthiness certificate) and kept valid by ongoing inspections and maintenance.
Context Anchor
Encountered during preflight risk assessment, aircraft dispatch, maintenance record checks, and instructor decisions about whether an aircraft may be used for a lesson.
Derivation
Airworthy' combines 'air' with 'worthy,' meaning 'fit for' or 'deserving of' — so 'airworthy' literally means 'fit for the air.' 'Official' here signals that this fitness is not just the pilot's opinion; it is formally established and recorded by the FAA.
Why Pilots Care
Confirms the aircraft is both safe and legal to fly; operating without it risks regulatory violations or accidents.
Intuition Check
Do not assume “official airworthiness status” means the airplane simply appears to be in good shape. Here, it means the aircraft’s legal and safety condition as shown by required FAA documents, inspections, and maintenance records.
Example Sentence 1
Before accepting the aircraft for the flight, the instructor confirmed its official airworthiness status by reviewing the airworthiness certificate and the most recent inspection entries in the logbooks.
Example Sentence 2
Without current official airworthiness status the instructor canceled the lesson.
