Aircraft GuidesPrivate Jet Maintenance Cost Per Year and Per Hour (2026)
How much it costs to maintain a private jet per year, per month and per flight hour: inspections, engine programs, major checks and reserves.
Buyers price a business jet on its engines and its logbooks, and maintenance keeps both in good order. Experienced buyers read the maintenance records before they look at the cabin.
The manufacturer sets a maintenance schedule and the aviation authority approves it, measured in flight hours, landings (cycles) and calendar time. Engineers record every task. If you defer work, the next owner deducts the cost from the price you get.
Owners who budget per flight hour have the money ready when the big bills come.

1. How Jet Maintenance Is Scheduled
Each type's maintenance program lists hundreds of tasks, each due after a set number of hours, cycles or months, whichever comes first. Engineers group the small tasks into regular inspections and the big ones into major inspections every few years, when the aircraft spends weeks in a hangar.
Some limits run on the calendar, so a jet that sits in the hangar still needs maintenance. A year parked still counts toward inspections and part lives.
- Line maintenance: daily and pre-flight checks, small fixes, done by the crew or local engineers
- Scheduled inspections: every few hundred hours or 12 months, a few days to two weeks
- Major inspections: often at 6, 8, 10 or 12 years (depending on type), weeks to months in the hangar
- Engine events: hot-section inspections and overhauls at set hour or cycle limits
- Mandates: airworthiness directives and service bulletins, plus airspace-driven avionics upgrades
2. Engines: The Biggest Single Cost
Engine makers set fixed intervals for inspections and overhauls, often every 3,000 to 7,000 hours. An overhaul on a light-jet engine can cost $600,000 to $1.2 million; on a large-cabin jet engine, $2 million to $4 million or more, per engine.
Most owners enrol their engines on an hourly maintenance program from the engine maker or a specialist provider. You pay a fixed rate for each hour flown, and the program pays for scheduled overhauls and most unscheduled repairs. You budget a known cost per hour instead of a multi-million-dollar bill.
| Category | Engine program (per engine, per hour) | Typical overhaul if not enrolled |
|---|---|---|
| Light jet | $220 to $350 | $0.6M to $1.2M per engine |
| Midsize / super midsize | $350 to $500 | $1.2M to $2.2M per engine |
| Heavy / ultra long range | $550 to $900 | $2M to $4M+ per engine |
