In an AOG situation, don’t rely on one supplier. Use a platform like Aviatrading.com to reach multiple verified sellers at once. Always search with the exact part number, confirm availability, and request certification upfront. Acting fast and smart helps reduce downtime and gets your aircraft back in operation quickly.
AOG (Aircraft on Ground)
When an aircraft is grounded, every minute matters.
An AOG (Aircraft on Ground) situation is one of the most stressful moments in aviation. Flights are delayed, operations are disrupted, and costs start adding up fast. In many cases, the issue comes down to one thing: a missing or faulty aircraft part.
The challenge is not just finding the part—it’s finding it fast, from a reliable source, and with the right certification.
In this guide, you’ll learn exactly how to find aircraft parts quickly during AOG, what to avoid, and how platforms like Aviatrading.com help you reduce downtime and get your aircraft back in the air faster.

Why AOG Parts Sourcing Is Different
When an aircraft is stuck on the ground, the clock starts ticking fast. Every delay means lost revenue, missed schedules, and growing pressure on your team to fix the issue quickly. In these moments, finding the right aircraft part is not just important—it’s urgent. The faster you locate a reliable, certified part, the sooner your aircraft can get back in the air.
Not all aircraft parts sourcing is the same.
In normal situations, you have time to:
- Compare suppliers
- Negotiate pricing
- Wait for lead times
But during AOG, everything changes.
You need:
- Immediate availability
- Fast response from suppliers
- Verified and certified parts
- Quick logistics and shipping
There’s no room for delays or uncertainty. One wrong step can cost hours—or even days.
Step-by-Step: How to Find Aircraft Parts Fast During AOG
1. Start with the Exact Part Number
Speed starts with accuracy.
Always search using the exact part number (P/N). Even a small mistake can send you in the wrong direction.
Also:
- Check for alternate or interchangeable part numbers
- Confirm with your maintenance team if substitutes are acceptable
This step alone can save a lot of time.
2. Use Multiple Sources at the Same Time
One of the biggest mistakes during AOG is relying on a single supplier.
Instead:
- Reach out to multiple vendors at once
- Use global sourcing, not just local contacts
- Avoid waiting for one response before contacting others
The more sources you check, the higher your chances of finding the part quickly.
3. Use an Online Aviation Marketplace
This is where things really speed up.
Instead of sending emails back and forth, platforms like Aviatrading.com allow you to:
- Search across a wide inventory in seconds
- Access multiple sellers in one place
- Compare availability quickly
- Get faster responses
This removes the need to manually contact dozens of suppliers.
For AOG situations, this kind of access can make a huge difference.
4. Focus on Verified and Trusted Sellers
Speed is important—but trust is just as important.
You don’t want to waste time dealing with unreliable sources.
Look for:
- Verified suppliers
- Clear company details
- Good communication response time
On Aviatrading, sellers are vetted, which helps reduce the risk of delays or issues.
5. Ask for Certification Immediately
Don’t wait until later.
When you find a part, ask for certification right away:
- FAA 8130-3
- EASA Form 1
- Traceability documents
If the seller cannot provide this quickly, move on.
In AOG, you don’t have time to fix documentation issues later.
6. Confirm Availability and Location
Not all “available” parts are truly ready to ship.
Always confirm:
- Is the part physically in stock?
- Where is it located?
- How fast can it be shipped?
A part across the world may not help if it takes too long to arrive.
7. Arrange Fast Logistics
Finding the part is only half the job.
You also need:
- Express shipping
- Same-day dispatch (if possible)
- Clear coordination with logistics providers
Work with sellers who understand AOG urgency and can move quickly.
Common Delays to Avoid
Even experienced teams lose time because of small mistakes.
Avoid these common issues:
- Waiting too long to contact multiple suppliers
- Sending incomplete RFQs (missing part number, condition, etc.)
- Not asking about certification early
- Relying only on email instead of faster channels
- Ignoring global inventory options
Each of these can add unnecessary delays.

The first six hours of an AOG, hour by hour
Most AOG events are lost in the first six hours, not in transit. The sequence below is what disciplined maintenance control centres run, and it is the sequence buyers follow when they post an emergency request on Aviatrading.
- H+0 to H+1 — confirm the part, not the symptom. Pull effectivity from the IPC, confirm the part number together with any approved alternate or superseded number, and record the serial and position. A request built on a symptom rather than a part number burns the first two hours of supplier time.
- H+1 to H+2 — check what you already own. Own stock, pool agreements, sister-fleet aircraft, consignment stock held at line stations. The cheapest AOG part is the one already inside your own network.
- H+2 to H+3 — broadcast, do not phone around. One structured RFQ sent simultaneously to many verified sellers beats twenty sequential calls. Sequential calling is how a six-hour AOG becomes a two-day AOG.
- H+3 to H+4 — qualify offers on paperwork, not price. A part that arrives without an acceptable airworthiness release is not a part. It is a delay with freight charges attached.
- H+4 to H+6 — lock logistics before you lock the deal. Confirm routing, the last acceptable tender time for the flight, dangerous-goods classification where applicable, and who clears customs at destination.
What to put in an AOG request so it gets quoted first
Sellers triage AOG requests in seconds. A request containing all of the following gets quoted first, simply because it can be quoted without a round of clarifying questions:
- Part number, and whether alternates or superseded numbers are acceptable
- Quantity and acceptable conditions in order of preference — NE, NS, OH, SV, AR
- Required release document: FAA Form 8130-3, EASA Form 1, dual release, or manufacturer C of C
- Trace requirement: back to birth, back to a named operator, or last operator only
- Destination airport code and the drop-dead arrival time in UTC
- Whether exchange or loan is acceptable instead of outright purchase
- A named contact reachable outside office hours
That last line matters more than most buyers expect. A meaningful share of AOG quotes expire unanswered because nobody picked up the phone at 02:00 local time.
When the OEM lead time is ninety days
New-from-OEM is one of five routes, and rarely the fastest. The practical options, in the order an experienced buyer works through them:
- Exchange. A serviceable unit ships immediately against your core. Fastest route for rotables. Watch the core return window and the beyond-economic-repair clause.
- Used serviceable material. Teardown stock with an acceptable tag and full trace. Availability is highest on mature platforms — CFM56, Boeing 737 Classic and NG, Airbus A320ceo, ATR.
- PMA. An approved alternative to the OEM part where the design approval exists and your CAMO and lessor accept it. Check the lease agreement before you check the price.
- Repair rather than replace. If a shop can restore the unit inside your ground time, this beats sourcing entirely.
- Loan. Buys days while the permanent solution is procured. The daily rate is high, an idle aircraft is higher.
The paperwork that stops an AOG part at the door
The most expensive AOG failures happen after the part lands. Common causes, all avoidable at the quoting stage:
- A release document issued by an organisation that is not accepted by your authority of registration
- A tag that references a part number the aircraft is not effective for
- A trace chain with an unexplained gap between operators
- Shelf-life or cure-date expiry discovered on receipt inspection
- Missing dangerous-goods declaration on a battery, chemical or pressurised unit
Each of these is a question you ask before you accept the quote, not after. Our guide on verifying aircraft parts certification covers the document checks in detail, and the certification and traceability guide explains what a complete trace chain looks like.
Reducing the next AOG before it happens
AOG response is a symptom-level fix. The structural fixes sit upstream: rotable pool coverage on the parts that actually ground aircraft, a pre-qualified seller list so no time is spent vetting under pressure, agreed conditions and trace standards documented in advance, and consignment stock at the stations where your fleet spends the night. Operators who do this consistently do not eliminate AOG events — they turn a two-day event into a six-hour one. See also how to reduce aircraft downtime caused by parts shortages.
