Why Big Maintenance Bills Are Often the Real Reason a Jet or Turboprop Comes to Market

Ask most owners why they’re selling their aircraft, and you’ll hear the usual answers: changing mission needs, upgrading to something bigger or faster, less time to fly.

All valid. But there’s a trigger that rarely makes it into the listing description, one I’ve seen fairly often on older private jets and turboprops, both in aircraft sales and in my earlier years working at an EASA Part 145 / Part M organization.

A big maintenance package is coming due, and the owner decides it’s cheaper to sell than to pay for it.

In aircraft sales, you see this pattern up close: an engine overhaul or hot section inspection, a landing gear overhaul, a heavy structural check, avionics obsolescence. Instead of writing that check, many owners quietly start looking for a buyer.

Example 1: The engine that’s “almost due”

Take a turboprop or jet that was never enrolled in an engine program (like JSSI or a manufacturer’s ESP plan). The logs show the engines are just a few hundred hours from overhaul.

On paper, the aircraft still flies perfectly fine. But any serious buyer’s pre-purchase inspection will flag it immediately, and it becomes a major negotiating point.

Owners in this position tend to split into two camps:

→ Some invest in the overhaul to protect the aircraft’s value and sell later at a stronger price.

→ Others decide that spending several hundred thousand euros on an aircraft they’re already planning to replace isn’t worth it. So they sell now, priced to reflect the upcoming overhaul, and let the next owner deal with it.

Example 2: The 10,000-hour inspection

This is a major structural and airframe milestone typically required for high-time light, midsize, and super-midsize jets, think Learjet 45s and legacy Citation models.

These inspections can be extensive: weeks, sometimes months of downtime, and a bill that can run well into six figures depending on aircraft type and findings.

Rather than commit to that kind of expense and downtime, owners frequently choose to sell shortly before the milestone hits. It’s a rational decision, the money and time required often exceeds what it adds back to resale value, especially for an owner who wasn’t planning to keep the aircraft another 10+ years anyway.

What this means if you’re buying or selling

For buyers: always check where the aircraft sits relative to major maintenance milestones, engine hot section/overhaul, landing gear overhaul, structural inspections, and whether it’s enrolled on any program. It’s one of the most valuable things a pre-purchase inspection tells you, and it directly affects your true cost of ownership.

For sellers: if you know a big package is approaching, timing matters. Selling ahead of it can make sense, but so does transparency. Buyers and brokers will find it during due diligence regardless, and pricing the aircraft accordingly from the start builds trust and speeds up the deal.

Having spent time on the maintenance side before moving into aircraft sales, this is a pattern I’ve seen play out again and again, and it’s exactly the kind of detail we help both buyers and sellers navigate at FA Aircraft Sales.
