US-FAA14 CFR 91.417
Maintenance records
Read the official ruleIn plain English
The owner/operator must keep maintenance records: records of maintenance and inspections (which may be discarded after 1 year or when the work is superseded), and permanent records (total time in service, current AD status, current inspection status, and the status of life-limited parts) that transfer with the aircraft.
Key points
- Keep both "temporary" work records and permanent status records.
- Permanent records: time in service, AD compliance, inspection status, life-limited parts.
- Records transfer with the aircraft on sale.
Common pitfalls
- Losing AD-compliance history — it can ground a sale or an annual.
