FAR 91.417 Explained
This rule matters because recordkeeping problems rarely show up at a convenient time. They show up during a sale, an inspection, a maintenance dispute, or the exact moment someone needs to trust the history fast.
What the rule covers
FAR 91.417 requires retention of records related to maintenance, preventive maintenance, and alterations, plus records showing current status of life-limited parts, time since overhaul, current inspection status, and applicable airworthiness directive status.
What has to transfer with the aircraft
Some records are not just “keep this around for yourself” records. They are part of the aircraft’s ongoing history and have to transfer with the aircraft at sale.
That is why messy or incomplete records hammer trust and value. A buyer is not just evaluating the machine. They are evaluating the continuity of the record system.
What the rule does not do
FAR 91.417 does not rescue bad entries. It does not replace the separate rule that governs what must be in the maintenance entry itself. That is where FAR 43.9 comes in.
Common real-world mistake
Owners often think they are compliant because they “have the paperwork somewhere.” That is not the same as having a coherent record set that can be reviewed, transferred, and understood without archaeology.
Why digital structure helps
- It keeps transfer-required history grouped with the aircraft.
- It helps current status items stay visible instead of buried.
- It reduces the risk that supporting documents get separated from the relevant entries.
