N-number changes and reuse: matching the right aircraft
Match the airframe, not just the registration text. A current registry entry cannot by itself prove that an older accident or service report belongs to the same aircraft.

Why the mark alone is insufficient
The FAA provides procedures for changing N-numbers. Treat a registration as a dated alias. The aircraft’s manufacturer, model and serial evidence must be considered alongside the date of the observation.

Build a small identity timeline
For each document, write down what it actually says. Preserve disagreements instead of choosing whichever identity produces a more reassuring result.
| Evidence | Record in your timeline |
|---|---|
| Aircraft document | Manufacturer, model, serial and document date. |
| Registration observation | N-number and known effective interval. |
| Historical event | Event date and identity fields recorded at that time. |
| Uncertain link | Which supporting field or interval is missing. |
Resolve conflicts before drawing conclusions
A matching serial can be useful evidence, but source errors, formatting and incomplete date intervals still need attention. A different serial or incompatible model is a reason to stop the association. When the dates do not establish who held the mark, leave the historical link unresolved.
- Compare the original fields without silently correcting them.
- Ask for documents supporting former marks and changes.
- Keep excluded events visible as excluded, not as part of this airframe’s history.
- Do not interpret unresolved identity as a clean result.
How this appears in an Aerovidence report
Registration facts, linked events, different-airframe observations and unresolved matches have separate roles. Read the identity explanation before using an event to shortlist an aircraft. If the report presents a conflict, collect better dated documents; a repeated search of the same edition does not add evidence.
