Records export integrity
Maintenance-data export validation
Maintenance-data export validation checks that a data file leaving one system is complete and faithful to the records before a buyer, lessor, or new system relies on it. It is run when records are exported for a transaction or a system change, by or for the party producing the file. It covers completeness against the source, field fidelity, and whether the export carries the trace a receiver needs. You receive a validation report, a list of records or fields the export dropped or distorted, and confirmation of what the file can and cannot be relied on for.
When this review is needed
- Records are being exported for a buyer or lessor and the file has to be trustworthy on receipt.
- An export feeds a new system and incomplete data would corrupt the load on arrival.
- A prior export was rejected as incomplete and the producer wants it right this time.
- A receiver requires confirmation the export faithfully represents the source.
The problem
An export looks done when the file generates without an error, but the file rarely carries everything the source holds. Filters, date ranges, and field limits silently drop records, and attachments or document references can fall away while the structured rows survive. The producer hands over a file that looks whole, and the gap becomes the receiver's problem.
What gets reviewed
- Record completeness in the export against the source counts and scope
- Field fidelity for serial numbers, counters, and dates
- Release and document references carried with the structured data
- AD and SB records represented faithfully in the file
- What the file can and cannot be relied on for, stated plainly
Scope this review
Tell us the asset, the event, and the evidence in scope, and we will outline a focused first engagement.
Send a representative, redacted record set and we will scope the review.
What gets validated
- Record counts and scope in the export match the source within the agreed boundary
- Serial numbers, counters, and dates in the export match the source values
- Document and release references in the file resolve to real attachments
- AD and SB records in the export agree with the source status
- Date ranges and filters applied to the export are accounted for in the stated boundary
Evidence normally required
- The export file to be validated
- Source system access or extracts to compare against
- The export specification or the receiver's data requirement
- A sample of records with known content for spot-checking
Common discrepancies
What is at stake
A receiver who builds on an incomplete export inherits gaps they did not create and may not detect until a trace is needed. For a transaction, an export that misrepresents the records can be treated as a misstatement of the asset, which is harder to walk back after handover.
How the work runs
Define the boundary
Establish what the export is supposed to contain against the source.
Compare counts and fields
Check completeness and field fidelity against the source records.
Test the references
Confirm document and release references resolve to real content.
State reliance
Report what the file supports and where it falls short.
What the buyer receives
- A validation report on completeness and fidelity against the source
- A list of records or fields the export dropped or distorted
- A statement of what the file can and cannot be relied on for
Who uses the output
- Producers handing a buyer or new system a file they can stand behind
- Receivers deciding how far to rely on the export they were given
- Transaction teams who need the export to represent the asset faithfully
How the work fits into the transaction or program
Validation runs at the producing end, before the file leaves, so completeness and fidelity are confirmed against the source rather than discovered by the receiver. The reliance statement it produces travels with the file into the transaction or the receiving system.
Start with a single asset
Prove the review on a single tail, then scale across the fleet.
Regulatory limits
Validation confirms the file is complete and faithful to the source records. It does not warrant the underlying maintenance, accept the records on a receiver's behalf, or make any airworthiness determination.
What this review does not cover
- Generating or formatting the export itself
- Loading the file into the receiving system
- Any airworthiness determination on the exported records
Specific to this review
- An export that generates without an error can still be incomplete, because filters and field limits drop data silently.
- Attachments and document references are the most common casualty: structured rows survive while the documents they point to fall away.
- For a transaction, an export that misrepresents the records can be read as a misstatement of the asset, so fidelity is checked before handover.

Frequently asked questions
Isn't this the same as the receiving system's import check?
An import check confirms the file loaded. This validates the file against the source before it leaves, so the producer knows it is complete and faithful rather than learning of gaps from the receiver after handover.
