Parts and conditions
Know exactly what you are buying, before you buy it.
Condition codes are not marketing language. Each one carries a specific meaning and a specific level of documentation, and we state both on the quote, not after the sale.
Part classes
Rotable
Designed to be repaired repeatedly and returned to serviceable stock after overhaul, rather than discarded when it develops a defect. Typically tracked by serial number across its service life.
Avionics line replaceable units, hydraulic pumps, landing gear actuators
Repairable
Can be repaired when it fails, but only for a limited service life or a limited number of repair cycles before it must be retired. Repair extends useful life without resetting it indefinitely.
Wiring harnesses, some composite panels, select structural brackets
Expendable
Usually not worth repairing, so it is discarded and replaced rather than sent to a repair station. The cost and complexity of repair rarely justify recovering the part.
Filters, gaskets, light bulbs, small mechanical fittings
Consumable
Used up during maintenance or operation and cannot be reinstalled once applied. Stock is tracked by quantity and shelf life, not by serial number.
Sealants, fluids, rivets, fasteners
Parts and conditions
Condition codes
FN
Factory New
- What it means
- Never installed and shipped directly from the original manufacturer, with zero operating time or cycles. This is the highest confidence condition available, since the part has not left the OEM's controlled chain of custody.
- Paperwork
- Typically accompanied by an OEM certificate of conformance or an FAA Form 8130-3 issued by the manufacturer.
NE
New
- What it means
- Unused and with zero operating time, but sourced through a distributor's stock rather than shipped straight from the OEM production line. Functionally equivalent to factory new for installation purposes.
- Paperwork
- Comes with a certificate of conformance from the distributor and, when available, the original OEM release documentation.
NS
New Surplus
- What it means
- New and never installed, but obtained outside the manufacturer's original distribution channel, usually as surplus stock from an operator or MRO shop. Condition is equivalent to new, though the paper trail back to the OEM may be shorter.
- Paperwork
- Usually accompanied by a certificate of conformance or a trace to source statement from the seller of record.
OH
Overhauled
- What it means
- Disassembled, inspected, repaired and tested by a certified repair station following the manufacturer's overhaul manual. For the parameters covered by that manual, the part returns to a zero time baseline, even though the physical unit is not new.
- Paperwork
- Released with an FAA Form 8130-3 (or an equivalent authority form) identifying overhaul as the work performed.
SV
Serviceable
- What it means
- Inspected and approved for installation, but without a full overhaul. The part retains its accumulated operating time, and any life limited components keep counting from where they were.
- Paperwork
- Typically released with an FAA Form 8130-3 or equivalent, referencing inspection rather than overhaul.
RP
Repaired
- What it means
- A specific defect was corrected by a certified repair station, without a full overhaul of the unit. Accumulated operating time is retained, and the repair addresses only the discrepancy that was found.
- Paperwork
- Released with an FAA Form 8130-3 or equivalent, describing the repair performed and the applicable data used.
IN
Inspected
- What it means
- Examined and found airworthy in its current state, without any repair work performed. This condition confirms the part is safe to install as is, based on the inspection criteria applied.
- Paperwork
- Usually accompanied by an inspection report or an FAA Form 8130-3 referencing inspection only.
AR
As Removed
- What it means
- Removed from an aircraft or assembly with no inspection performed afterward. Actual condition is unknown until a certified repair station evaluates the part, so buyers should budget for testing before installation.
- Paperwork
- Typically comes with a removal tag or a trace to source statement, not an airworthiness release.
BER
Beyond Economical Repair
- What it means
- The cost of repair exceeds the value of the part, so it is not returned to service. These units are typically sold for material recovery or as an internal source of spare components.
- Paperwork
- Sold with a condition statement identifying the unit as BER, without an airworthiness release.

What to include in a request
- 01
Part number
The exact number off the removed part or the manual, including any dash number or revision.
- 02
Quantity
How many units you need, so availability and pricing reflect the actual order.
- 03
Acceptable condition
Whether new, overhauled, serviceable or as removed is acceptable, or whether only one condition will do.
- 04
Aircraft tail number
Helps us confirm fit and check for any applicable airworthiness directive or service bulletin.
- 05
Reason for removal
Scheduled replacement, failure, or damage, this context helps us find the right alternate if the exact part is not on hand.
