Condition codes explained
Updated Sep 18, 2026 MST
Every part is listed with a condition code so you know exactly what you are buying — and what paperwork to expect. Codes follow standard FAA-style usage; the certification a part carries always depends on its condition and is shown on the listing.
- FN Factory New Airworthy-capable
- Brand-new from the original manufacturer's production line, never installed or operated, supplied with full manufacturer documentation.
- Certification typically expected: 8130-3 / C of C
- NE New Airworthy-capable
- New and unused in original packaging. May be OEM or authorized-distributor stock issued with new certification.
- Certification typically expected: 8130-3 / C of C
- NS New Surplus Airworthy-capable
- New, unused stock that has left the original supply chain (overstock or old stock). Unused, though it may carry an older manufacture date.
- Certification typically expected: 8130-3 / trace
- OH Overhauled Airworthy-capable
- Disassembled, cleaned, inspected, repaired as necessary, reassembled and tested to the manufacturer's overhaul limits — restored to zero-time where the data permits.
- Certification typically expected: 8130-3 (dual-release)
- IN Inspected Airworthy-capable
- Inspected against the applicable data and found airworthy. The inspection findings are disclosed on the part tag.
- Certification typically expected: Inspection record
- SV Serviceable Airworthy-capable
- Inspected and found within serviceable limits — airworthy and fit for return to service, but not zero-timed like an overhaul.
- Certification typically expected: 8130-3 / serviceable tag
- RP Repaired Airworthy-capable
- A specific defect was repaired and the unit returned to a serviceable condition. A targeted repair, not a full overhaul.
- Certification typically expected: 8130-3
- AR As Removed Not airworthy as-is
- Removed from an aircraft "as is" with no testing, repair or paperwork implied. Airworthiness MUST be established by an appropriately rated person before installation.
- Certification typically expected: None — as-is
Codes describe condition, not installation eligibility. The installing A&P/IA makes the final airworthiness determination for your aircraft. How traceability works →
