Aircraft buyer guide
Missing aircraft logbooks: questions to resolve before buying
First identify exactly which aircraft, component and period lack records. Ask a qualified mechanic to assess the missing evidence and any supporting documents. A public registration or accident search cannot reconstruct absent maintenance entries or certify the aircraft’s condition.

Describe the gap before trying to resolve it
“Missing logs” can mean an absent volume, an unexplained period, a component history gap or a referenced document that was never supplied. These need different follow-up. Preserve the seller’s statement as a statement and the documents received as evidence; do not merge them into one verified history.
| Gap | Information to record |
|---|---|
| Missing volume or period | Last supplied entry, next supplied entry and the subject identity. |
| Engine or propeller records | Component model and serial, installation references and supplied dates. |
| Uncertain times or part status | The conflicting entries and documents needed for review. |
| Missing AD or repair evidence | Directive or work reference, claimed action and the absent support. |
Ask which retained records are relevant
14 CFR 91.417 distinguishes work and inspection records from continuing status records, with different retention and transfer provisions. It includes items such as total time, life-limited part status, inspection status and applicable AD status. Use the current rule and FAA maintenance-record guidance with the mechanic; an empty period alone is not a legal determination that a required record was lost.

Request traceable copies from known sources
Through the seller or an authorized contact, request relevant shop records, work orders and previously supplied copies. Use the FAA records-copy service for documents it holds. Label each copy with its source and receipt date; do not represent a new summary as an original log entry.
- Create an itemized request for the missing documents.
- Record who supplied each response and what period it covers.
- Retain illegible or incomplete responses with their limitations.
- Let the mechanic identify what the new evidence resolves and what remains unknown.

Do not fill the gap with a public-data result
No matching NTSB record does not mean no damage occurred. A model SDR record does not document this airframe’s maintenance. An AD reference does not show that required work was performed. Keep those public-source observations alongside, but separate from, the absent aircraft-specific evidence.
Make the next decision depend on the unresolved evidence
Ask the independent reviewer for a written list of open questions, additional inspections or documents needed, and the limits of their conclusions. Discuss purchase conditions and valuation with the relevant advisers. This guide does not set a universal discount, declare the aircraft unairworthy or approve a purchase.
