The Beechcraft King Air 350i is the benchmark cabin-class twin turboprop — the airplane other twin turboprops are measured against, prized for its ramp presence, payload, and decades of operator data that make credit committees comfortable. Financing a 350i is a different exercise from a piston airplane: loans run into the millions, specialized aviation lenders are involved, and engine programs, insurance, and intended use all shape the structure. Here's how it works in 2026.
Key takeaways
- A multi-million-dollar loan. Used 350is span roughly $3M (older EFIS retrofits) to $6M+ (low-time Pro Line Fusion aircraft).
- Specialized lenders, larger down. Expect 15–20% down and terms that often blend a longer amortization with a balloon.
- Engine programs matter. PT6A coverage (an hourly engine program) strongly supports value and financing.
- Insurance and training gate the deal. Turbine time, training, and a two-crew SOP for some operators drive premiums; coverage must bind before funding.
- Rates are illustrative. Turbine borrowers with strong financials generally see the upper 6% to mid-7% range in early 2026. Jaken Aviation is a brokerage, not a lender.

What a King Air 350i Costs in 2026
The 350i is a used-market airplane today (the current-production King Air is the 360). Values track avionics (Collins Pro Line 21 vs. Fusion), engine program status, total time, and interior/paint condition.
| Model / vintage | Typical price range | What drives it |
|---|---|---|
| Low-time Pro Line Fusion 350i | ~$5.0M–$6.5M | Fusion avionics, low hours, engine program |
| Mid-time 350i (2010s) | ~$3.8M–$5.0M | Pro Line 21, engine program, condition |
| Older 350 / early 350i | ~$3.0M–$3.8M | Higher time, avionics retrofits, program status |
Illustrative Financing Rates & Terms
Turboprops finance through specialized aviation lenders that weigh the borrower's financial strength, the engine program, and intended use. These ranges are illustrative for early 2026, not offers; see our aircraft loan rates guide for the full picture.
| Buyer / aircraft profile | Credit tier | Illustrative APR | Typical down | Typical term |
|---|---|---|---|---|
| Strong financials, engine program | Strong (720+) | upper 6% – 7.25% | 15–20% | 15–20 yr amort (balloon common) |
| Good credit, mid-time | Good (680–719) | 7.25% – 8% | 20% | 10–15 yr amort |
| Older airframe / off-program engines | Strong (720+) | 7.5% – 8.5% | 20–25% | 10–12 yr |
| Flight department (DSCR-based) | Business | priced on cash flow | 15–25% | structured |
Engine Programs, Insurance & Intended Use
Three turbine-specific factors dominate a 350i financing:
- Engine program status. The PT6A engines are typically enrolled in an hourly maintenance program. An airplane on a recognized program is far easier to finance and value than one with off-program, high-time engines — lenders treat program coverage as collateral protection.
- Insurance and training. Turbine insurance is priced on your turbine and type time. Owner-operators new to the type should expect formal training (e.g., a recognized simulator course) and, in some cases, a mentor-pilot or two-crew requirement in year one. The lender needs coverage bound at closing, so start early.
- Part 91 vs. 135 and flight-department use. If the airplane will be chartered or run by a flight department, lenders may underwrite on a debt-service-coverage basis and want the management and crew plan documented. See our business financing guide.
Structure note: turbine loans often pair a 15–20-year amortization with a balloon at 5–10 years to keep payments manageable. A broker can compare amortizing vs. balloon structures across lenders for your cash-flow goals.

| 2010 350i, strong credit | $4,200,000 | 20% ($840,000) | $3,360,000 | 7.25% / 15 yr | ~$30,670 |
| Older 350, good credit | $3,200,000 | 25% ($800,000) | $2,400,000 | 7.5% / 12 yr | ~$25,325 |
Total Cost of Ownership
A cabin-class turboprop's operating budget is substantial — plan for it:
- Fuel: two PT6A engines burn on the order of 90–110 gallons of Jet-A per hour in cruise.
- Engine program: an hourly reserve/program is the norm and materially affects both cost and financing.
- Insurance: turbine premiums, sensitive to your turbine time and the crew model.
- Crew & training: recurrent training (and, for some, contract or salaried crew) is a real line item.
- Hangar & maintenance: a large twin turboprop needs hangar space and scheduled inspections.

Frequently Asked Questions
How much do I need to put down on a King Air 350i?
Typically 15-20% for a well-qualified buyer, more on older or off-program aircraft. Turbine lenders weigh your overall financial strength and the engine program status alongside the down payment. These are typical ranges, not guarantees.
What is an engine program and why does it matter?
PT6A engines are usually enrolled in an hourly maintenance program that covers major engine events. An airplane on a recognized program is easier to finance and holds value better, because the lender sees the engines as protected collateral.
Can I finance a 350i for charter (Part 135)?
Yes. Flight-department and charter aircraft are commonly financed, often on a debt-service-coverage basis. Lenders will want the management, crew, and utilization plan documented.
Do turboprop loans use balloon payments?
Often. Turbine loans frequently pair a long amortization with a balloon at 5-10 years to keep payments manageable. A broker can compare fully-amortizing and balloon structures for your cash-flow goals.
Are the rates in this guide guaranteed?
No. Every figure is illustrative for planning only. Jaken Aviation is a brokerage, not a lender; your actual offer comes from a lender after a full application and is subject to credit approval.
