Do Not Use the Seller's Shop

There is this old myth out there that the best shop to do the pre-buy is the one that has been maintaining the airplane all along because they know the airplane best. On the surface, that sounds logical. But in reality, that can be a conflict of interest.

That shop has been working for the seller, not for you. They have likely been doing the annuals, repairs, and maintenance over time. So whether they mean to or not, there is already some loyalty there. You, as the buyer, need somebody who is looking at that aircraft strictly from your side of the table.

"Do not use the seller's maintenance shop to do your pre-buy. That is probably the biggest mistake buyers make."

Independent Eyes Are the Whole Point

A good pre-buy should be independent. You want a shop or an inspection specialist who has no reason to protect the seller, soften the findings, or gloss over issues because they already know the airplane and have been the one maintaining it.

You want someone who is going to look at it objectively and tell you exactly what they see. That is the entire point of the pre-buy. You are trying to protect yourself before you spend a lot of money on the airplane.

Watch for Seller Red Flags

One of the things to pay very close attention to is how the seller reacts when you want to choose your own shop. If the seller does not want you to use anyone besides their shop, that is usually a red flag.

⚠ Red Flag

If the seller is pushing back hard on an independent inspection, limiting which shops the airplane can go to, or seems overly concerned about what a thorough pre-buy might cost — slow down. That can mean they are used to cutting corners, or they are worried a thorough shop is going to find things they do not want found. That does not automatically mean the airplane is bad, but it absolutely means you should protect yourself.

Go See the Shop If You Can

If the shop is local, one of the best things you can do is go there. Walk in. Look around. Trust your gut.

What to Look for When You Walk In

Does the facility look organized and clean for what it is?
Are the aircraft in an orderly workspace?
Does the staff seem professional and helpful?
Do they have the right tools and parts around them?
Does leadership seem accessible and knowledgeable?
Does the overall environment inspire confidence?

A lot of times your gut will tell you what you need to know pretty quickly. If you walk into a shop and it is dingy, disorganized, cluttered, and chaotic, that usually says something about how they operate — and in a lot of cases, that environment translates directly into the quality of the work.

Thoroughness Over Price — and Time Matters

You do not want the cheapest pre-buy. You want the right pre-buy. A cheap, rushed inspection can cost you a lot more later if it misses major issues. The right shop is going to take time to review the logs, inspect the aircraft properly, look for corrosion, check every applicable AD and service bulletin, and give you a real nose-to-tail list of findings.

"You do not want the cheapest pre-buy. You want the right pre-buy. A cheap, rushed inspection can cost you a lot more later if it misses major issues."

A solid pre-buy takes at least a full day — and on larger or more complex aircraft, sometimes longer. If someone is quoting you a two-hour walk-around and calling it a pre-buy, that is not the kind of evaluation you want to rely on before spending serious money. When choosing a shop, be much more focused on thoroughness, reputation, and professionalism than on trying to save a few hundred dollars on the inspection itself.

Reputation Still Matters

Word of mouth is still one of the best sources. If you know people who have bought airplanes before, ask them who they used and how the pre-buy went. Online reviews can help too — forums, owner groups, and aviation communities can sometimes point you in the right direction, especially when you see the same shop names come up more than once.

Use common sense with online comments since they can be biased or incomplete. But reputation as a whole is still a meaningful signal when choosing who to trust with a purchase this size.

At Paragon, pre-buy inspections are performed strictly as buyer-side evaluations. There is no relationship with the seller, no findings to soften, and no incentive other than giving you an honest, independent picture of exactly what you are buying.

Trust Your Gut — and Pay Attention to Early Warning Signs

More than anything, trust your gut. If something feels off with the shop, if something feels off with the seller, if they are pushing too hard toward one shop, if they seem too worried about the cost of a real pre-buy, or if they are resisting a thorough inspection — those are things you should pay attention to.

A lot of buyers ignore those early warning signs because they want the airplane to work out. That can be expensive. If you start seeing red flags with the shop, you may need to think twice not just about the shop, but about the airplane itself.

Frequently Asked Questions

Usually, no. That shop has been working for the seller, not for you, and that creates a conflict of interest. Whether they mean to or not, there is already loyalty there. As the buyer, you need your own independent shop or inspection specialist who has no relationship with the seller and no reason to soften the findings.
That is usually a red flag. A buyer should always be able to choose an independent shop or inspection specialist. If the seller is pushing back hard on an independent pre-buy, or limiting who can inspect the airplane, you should ask yourself why — and slow down before moving forward with the purchase.
Look for a shop that is organized, professional, and thorough. If you can visit in person, walk in and trust your gut — does the facility look clean and orderly, do the staff seem knowledgeable, and does it feel like a place that takes pride in its work? Beyond that, check reputation through word of mouth, owner forums, and aviation communities. Prioritize thoroughness over price.
A solid pre-buy inspection should take at least a full day, and in some cases longer depending on the size and complexity of the aircraft. If someone is rushing through it in just a couple of hours, not opening things up, not reviewing logs carefully, and not documenting what they found, that is probably not the kind of pre-buy you want to rely on.
No. A cheap, rushed pre-buy can cost you a lot more later if it misses major issues. You do not want the cheapest pre-buy — you want the right pre-buy. The right shop is going to take time to review logs, inspect the aircraft properly, check ADs and service bulletins, look for corrosion, and give you a real nose-to-tail list of findings.
