In aviation, every component must be trusted — not just by a buyer, but by pilots, mechanics, and the systems that depend on it. That trust starts with clear, standardized condition codes.
Whether you're sourcing parts for a repair station, maintaining a private aircraft, or just browsing online inventory, these short two-letter codes (like NE, OH, AR, etc.) carry big meaning. They're the industry shorthand for part history, serviceability, and value.
Let’s break down what these condition codes mean, and why using the correct one isn’t just good business — it’s essential to aviation safety and compliance.
What Are Aviation Condition Codes?
Condition codes are standardized abbreviations that describe the status and usability of an aircraft part or component. They help buyers, sellers, and maintenance personnel quickly understand what they’re working with — no guesswork required.
Think of them as a universal language in aviation logistics.
Why Standardized Codes Matter
- Avoid Miscommunication: A part listed as “good” is meaningless without a standard. “SV” (Serviceable), on the other hand, tells the buyer it has passed inspection and is ready to install.
- Compliance & Traceability: Many regulatory bodies (FAA, EASA, DoD) expect clarity and documentation. Using correct condition codes supports proper recordkeeping.
- Pricing Accuracy: A part listed as “NE” (New) will price vastly different from one marked “AR” (As Removed). Accurate coding avoids disputes and builds trust.
- Safety First: Knowing the true condition of a flight-critical component can literally be a life-or-death detail.
Common Aviation Condition Codes & What They Mean
Here’s a breakdown of the most widely accepted industry condition codes:
| Code | Meaning |
|---|---|
| NE | New – Brand new, never installed. Often with certification. |
| FN | Factory New – Direct from manufacturer with traceability and no prior use. |
| NS | New Surplus – New, unused, but may lack factory traceability. Still unused. |
| OH | Overhauled – Disassembled, inspected, tested, and restored per overhaul spec. Ready for use. |
| RB | Rebuilt – Returned to serviceable condition by manufacturer or certified repair facility. Often carries similar warranty to OH. |
| RD | Repaired – Fixed to serviceable condition, but not fully overhauled. |
| RP | Repairable – Not currently serviceable but can be repaired. |
| SV | Serviceable – Tested and verified as operational. Ready for use. |
| TST | Tested – Has been tested but may not be fully certified as SV. |
| IN | Inspected – Visual or bench-inspected, but not guaranteed operational. |
| AR | As Removed – Removed from service; untested, unknown condition. "Buyer beware." |
| CR | Core – Typically used for exchange programs. Expected to be repaired or overhauled. |
| EX | Exchanged – Replaced under a part swap or exchange program. Often rebuilt or OH. |
| BER | Beyond Economical Repair – Damaged or degraded beyond viable repair. Usually for scrap. |
| MO | Modified – Altered from original specs, often for performance or compatibility. |
| OR | On Request – Inventory not currently on-hand, but may be sourced on demand. |
| GS | Government Surplus – Previously owned by military or government; condition varies. |
The Impact on Buyers & Sellers
For sellers:
Using proper codes builds credibility. Buyers are more likely to return — and pay fair prices — when they trust your descriptions.
For buyers:
Understanding codes protects you from overpaying, buying unairworthy parts, or missing out on serviceable options that fit your needs.
