How to send an AOG request that gets fast quotes

A clear request saves hours of back and forth. Include every detail the supplier needs to quote immediately. Missing information causes delays.

• Part number and alternate part numbers if known. The alternate number helps if the main number is out of stock.
• Quantity needed. Be exact so the supplier can reserve the correct amount.
• Condition wanted. NE means new. NS means new surplus. OH means overhauled. SV means serviceable. AR means as removed or as is.
• Aircraft type and serial number if relevant. This helps confirm applicability.
• Delivery airport and country. Include the customs broker contact if you have one.
• Deadline or AOG status. State if the aircraft is on ground or if you need the part by a specific time.
• Paperwork needed such as FAA 8130-3 or EASA Form 1. Specify which form your authority accepts.

How to check a supplier before you buy

Before you send payment, check the supplier's quality credentials and the part's paperwork. This protects your operation from unapproved parts and delays. Do not assume that a low price means a good deal.

An FAA 8130-3 is an airworthiness approval tag. It is issued by the FAA or an authorized representative. It certifies that a part meets approved design data and is safe for installation. Check that the tag matches the part number and serial number.

An EASA Form 1 is the European equivalent of the 8130-3. It certifies that a part is airworthy and released by an EASA approved organization. Operators in Europe and many other regions require this form. Some parts may have dual release paperwork.

Traceability means you have records that show where the part came from and who owned it. Good records help prove the part is legitimate and not stolen or counterfeit. Ask for a back to birth trace if possible. This is especially important for rotable components.

ASA-100 is a quality standard from the Aviation Suppliers Association. It shows a supplier follows accepted practices for parts distribution, documentation, and storage. Many buyers require their vendors to hold this accreditation. You can check the ASA website for a list of accredited companies.

AS9120 is a quality management standard for aerospace distributors. It builds on ISO 9001 and adds requirements for traceability, counterfeit parts prevention, and handling. It is widely used to assess distributor quality systems. Ask your supplier for their certificate number.

FAA Advisory Circular 00-56 sets out the FAA's voluntary accreditation program for parts distributors. Under it, groups such as the Aviation Suppliers Association audit distributors against a set standard. A distributor that is accredited under AC 00-56 has had its quality system checked by a third party.

Suspected unapproved parts are a serious risk. Always ask for paperwork before you buy. If a price seems too low or the paperwork is missing, stop and verify. Unapproved parts can ground an aircraft and create safety and legal problems. Report suspected unapproved parts to your aviation authority.

FAQ

What does AOG mean?

AOG stands for aircraft on ground. It means an aircraft is out of service and needs a part or repair before it can fly again. The goal is to return the aircraft to service as quickly as possible. Maintenance planners and buyers work quickly to locate the required part and arrange delivery.

What is the difference between a broker and a distributor?

A distributor usually holds inventory and has direct contracts with manufacturers. A broker sources parts from multiple places and arranges the sale without always holding the stock. Both can help you find parts, but their supply chains differ. Distributors often provide warranties and traceability directly. Brokers add value by finding hard to locate stock across multiple sources.

What do NE, OH and SV mean?

NE means new. OH means overhauled. SV means serviceable. These condition codes tell you the state of the part and what work has been done. Always match the condition code to your maintenance program requirements. Using the wrong condition can violate your approved maintenance plan.

Is an 8130-3 enough on its own?

An 8130-3 is important but not the only thing to check. You should also verify traceability, supplier approval status, and that the tag is authentic and matches the part. A valid tag from an approved source is what makes the part acceptable. Compare the certificate details to the physical part markings.

How fast can an AOG part arrive?

Delivery time depends on location, customs, and shipping method. Many AOG brokers can ship within hours or by next day to major airports. You should confirm the exact delivery time with the supplier before you pay. Have your shipping account ready to avoid delays. Weekend and holiday shipments are often possible for critical AOG situations.
