Methodology
How we match and organize records.
A registration number can move between aircraft. We check the aircraft identity and record dates before linking its history.
How it works
From official records to your report
- 01Keep the source and date
We save the source reference and retrieval date so each result can be checked against the records used.
- 02Identify the aircraft
Manufacturer, model, serial number and registration history help distinguish the physical aircraft from its N-number.
- 03Organize service reports
Source-row summaries keep submission counts separate. For supported model groups, duplicate and supplemental reports are grouped before recurring patterns are evaluated. Reporting frequency is not a failure rate.
- 04Separate AD questions
Whether a directive applies, which parts are installed and whether work was completed are separate questions. Missing configuration stays unknown.
- 05Show findings and gaps
The report records what was found, what remains unknown and what to verify during a pre-buy review. It is a dated edition, not a live maintenance record.
Reading the results
What a report can tell you
It can show the records found in the listed sources and dates, explain supported aircraft matches, and identify model observations or questions for your inspector.
Before you buy
What still needs verification
- A report does not certify airworthiness, safety, reliability or physical condition.
- It is not a title opinion or ownership guarantee.
- AD applicability does not prove that work was completed on the aircraft.
- No matching NTSB record does not prove that no accident ever occurred.
- Missing records do not make an aircraft appear cleaner.
Dates and uncertainty
When the answer is unknown
Conflicting identity records, missing sources, incomplete configuration or small samples can prevent a conclusion. These limits remain visible in the preview and report. Source snapshots and calculation methods have separate versions.
