Aircraft registration vs airworthiness certificate: what to check
Registration and airworthiness certification answer different questions. Check each document and its applicable conditions separately, then have the maintenance records and actual aircraft reviewed. A current registration entry is not an airworthiness or AD-compliance finding.

Put the documents side by side
Use a document comparison to identify the next reviewer and question. Do not collapse registration status, certification and maintenance into one green “valid aircraft” result.
| Evidence | Question for the review |
|---|---|
| Registration record and certificate | Which aircraft and registration details are documented, and what dates or changes need confirmation? |
| Airworthiness certificate | Which certificate classification and aircraft identity are shown? |
| Operating limitations and supplements | Which documents apply to the aircraft’s certification and configuration? |
| Maintenance and AD records | What supports inspection, configuration and applicable directive status? |

Distinguish standard and special certification
FAA guidance distinguishes standard and special airworthiness certificates. Read the actual classification and supporting documents rather than assuming the same conditions for every aircraft. This guide does not determine operating eligibility for any category.

A standard certificate has continuing conditions
The FAA explains that a standard airworthiness certificate remains valid subject to conditions including conformity to the approved type design, condition for safe operation and required maintenance. Its existence in a file is therefore not a fresh inspection of the aircraft.

Handle a purchase or changed configuration as a review task
The FAA describes transferability of a standard certificate when an aircraft is sold, alongside registration and continuing-condition requirements. Ask the appropriate reviewer which documents and actions apply to the transaction. For an equipment or design change, reconcile the applicable approval and installation records with the aircraft.
- Compare identifiers across the registration and certification documents.
- List missing limitations, supplements or configuration records.
- Ask the mechanic to reconcile inspection and AD evidence.
- Resolve transaction and operating questions with the relevant qualified adviser or FAA office.

Use public lookup for the question it can answer
Aerovidence presents dated registration and covered event evidence, plus available source context in the free full report. It does not issue certificates, authorize a flight or determine aircraft-level AD compliance. A missing certificate field stays unavailable; it does not become a valid or invalid certification result.

Find the recorded aircraft registration expiration date, understand the current renewal rule, and compare the certificate with the latest FAA information.
Aircraft AD search: applicability is not compliance
Search FAA airworthiness directives using airframe, engine, propeller and equipment details, and separate possible applicability from compliance evidence.
Aircraft STC lookup: research a modification before a prebuy
Find FAA supplemental type certificate information, separate design approval from installed equipment, and prepare the supporting records for a prebuy.
