Aircraft Parts Condition Codes Explained

What New, Overhauled, Serviceable, As Removed, and other part conditions mean, so you know exactly what you are buying.

When you shop for aircraft parts, the listed condition tells you how the part was last verified, what work was performed on it, and what paperwork comes with it. The aviation industry uses both descriptive terms (such as Serviceable or Overhauled) and short condition codes (such as SV or OH). This guide explains the conditions you will see on Flying411 listings and the standard codes they map to, so you can compare parts with confidence.

Condition codes at a glance

Condition	Code	What it means
Factory New	FN	Brand new directly from the manufacturer, with full certification and warranty.
New	NE	Unused and in new condition, but may not carry full manufacturer traceability or warranty.
New Surplus	NS	New, never-installed stock that has been held in storage; often older but still unused inventory.
Overhauled	OH	Fully disassembled, cleaned, inspected, repaired as needed, reassembled, and tested back to the manufacturer's new-part tolerances, with overhaul paperwork.
Serviceable	SV	Inspected and found fit for installation, but not restored to new limits; may have less life remaining than an overhauled unit.

Inspected / Tested	IN	Examined and, where applicable, bench-tested and found to meet condition criteria, without a full overhaul.

Frequently asked questions

What is the difference between Overhauled (OH) and Serviceable (SV)?

An Overhauled part has been completely disassembled, cleaned, inspected, repaired as needed, reassembled, and tested back to the manufacturer's approved new-part tolerances, and it ships with overhaul paperwork. A Serviceable part has been inspected and found fit for installation, but it was not restored to new limits, so it may have less life remaining than an overhauled unit.

What does As Removed (AR) mean, and is it safe to buy?

As Removed means the part was taken off an aircraft or engine and sold in its current, untested state with no recent inspection. It can be a good value when bought for overhaul or as a core, but it is not ready to install. Always confirm whether trace or removal documentation is available and budget for inspection or overhaul before use.

Is a Serviceable part airworthy?

A Serviceable part has been inspected and determined to be fit for installation, and it normally ships with an airworthiness approval tag such as an FAA 8130-3. Final airworthiness still depends on installation by a qualified mechanic in accordance with the applicable maintenance data, so always review the accompanying paperwork.

What is the difference between New, Factory New, and New Surplus?

Factory New (FN) is brand new directly from the manufacturer with full certification and warranty. New (NE) is an unused part in new condition that may not carry full manufacturer traceability or warranty. New Surplus (NS) is new, never-installed stock that has been held in storage, often older inventory that is still unused.

What is an FAA 8130-3 form and why does it matter for condition?

An FAA 8130-3 (Authorized Release Certificate) documents that a part was inspected or maintained and found to conform to approved data. For conditions such as New, Overhauled, Repaired, and Serviceable, an 8130-3 or equivalent release is the paperwork that supports the condition claim and the part's eligibility for installation.
