A component part or material produced in conformity with approved data that is accompanied by a manufacturer's material certification at the time of sale and has no operating time or cycles.
A used component or part which has been overhauled using methods, techniques, and practices acceptable to the FAA and has been disassembled, cleaned, inspected, repaired as necessary, and reassembled. In addition, it has been tested in accordance with approved standards and technical data acceptable to the FAA.
A component that has been rebuilt to original tolerances. These parts are generally taken in on exchange, rebuilt completely under PMA, and are considered like "New". Generally, rebuilt components will be accompanied by an FAA Form 8130-3, and vendor PMA number will be referenced, when applicable, on the airworthiness certification document.
A material, component or part which has been examined by means of visual or test procedures to establish conformity with acceptable data. Generally, this class of part is inspected and tested with No Fault Found (NFF). Zenith Aviation is NOT a repair station or certified to conduct inspections or repairs but will provide test data if provided to us by a certified repair facility. When no inspection data is provided to us, we will provide only the airworthiness certificate that has been provided to us.
New Surplus (NS)
A component part or material that is unused and may have been released as surplus by the manufacturer, owner-operator, repair facility, etc. New Surplus parts from Zenith will NOT be delivered with certification paperwork (such as an OEM C of C or an airworthiness certificate), but MAY have an OEM or repair station tag (most often, but not always, with an inspection stamp), or the part may be sealed in original OEM packaging. All new surplus parts from our stock will have a Zenith Aviation CofC and trace document to our source.
If you are considering an NS part purchase, please speak with the salesperson about your trace and/or certification requirements BEFORE sending a purchase order.
A component or part which has been restored to a serviceable condition in conformity with data acceptable to the FAA.
A component or part which has been altered in conformity with approved data.
A material, component or part which has been examined by means of test procedures to establish conformity with acceptable data.
With the exception of "AR" parts, everything we sell is in "Serviceable" condition. This is an FAA term that means that the material, part or component meets the manufacturer's performance specifications, although a more accurate condition code could be used (such as Repaired, Overhauled, etc.). "SV" is a code that Zenith used in our previous inventory tracking system, and we are working diligently to more accurately identify and classify our inventory to reflect one of the conditions listed above. All "SV" parts are legally approved for installation and use but please inquire of your salesperson if you need more information about a part or its airworthiness certification documents.
As Removed (AR)
Parts that have no Release Certificate and are not certified for installation. AR parts will require AT LEAST testing/inspection, and possible repairs or modification to recertify prior to use. AR is not authoritatively defined within the industry, but Zenith Aviation defines this class of part as simply having been removed from a Next Higher Assembly (NHA). That NHA could be an aircraft, engine, or an assembly. Zenith makes bulk purchases of parts when airlines and/or corporate operators sell aircraft or close their doors, and as such can provide trace documents to that seller, but we are often able to provide NHA data or documentation to support it.
At Zenith Aviation, AR parts fall under 1 of 3 possible categories:
A component, part or material, the condition of which cannot certainly and accurately be classified and therefore its status is unknown. No guarantee is expressed or implied about the repairability of the part.
A component, part or material that was removed from an NHA and tagged by an operator with a suspected squawk, but the part has not been evaluated by a certified repair station to confirm the squawk.
Occasionally we send an AR part from our stock to a repair station for evaluation but do not complete the repair. If no sale is pending, or if the evaluation reveals a higher-than average repair cost we may decide to have the part returned to us in "as-is" condition until a need arises to have the part repaired. Under this category, the parts are evaluated and are found to be repairable, but no business need existed at the time of the evaluation for us to proceed with the repair. It is the buyer's responsibility to make sure the part they order meets their need prior to committing to the purchase. We can provide a full disclosure only when we understand your requirements, so please ask! We list these parts as AR even though we know the condition of the part.
Warning to purchasers!! AR parts are NOT compliant with FAA airworthiness requirements. Buyers are solely responsible for bringing the parts into compliance with 14 CFR part 21 or other applicable standards, by obtaining all necessary FAA inspections or modifications. If you are considering an AR part purchase, please speak with the salesperson about your trace requirements BEFORE sending a purchase order. To restate, NO guarantee is expressed or implied about the repairability or condition of our AR stock, and AR parts are sold "as-is, where-is".
