Diamond DA42 to DA62: Transition Training, Insurance, the Cost Delta and Financing the Step to Seven Seats
For DA42 Twin Star owners who already fly a diesel Diamond twin and want more seats, more payload and a bigger cabin, and need to know what the move costs to train for, insure, operate and finance.
The DA62 is the most natural twin step for a DA42 pilot. It keeps the composite airframe, the FADEC single-lever engine controls, the Garmin G1000-family panel, the retractable gear and Jet-A diesel power. It adds a longer cabin with up to seven seats, more useful load and a little more speed. It is not pressurized, whatever older marketing copy may suggest. This page covers the transition. For specifications and payment examples on each airplane, see the DA42 Twin Star and DA62 model pages.
Why DA42 owners move up to a DA62
The reasons are almost always seats and load. A DA42 is a four-seat airplane, and with full fuel and four adults it runs short of useful load quickly. The DA62 seats up to seven in three rows, and the U.S. version is certified at a 5,071 lb maximum takeoff weight, which gives it meaningfully more payload. Families that have outgrown four seats, business owners who carry a small team, and owners who want room for bags and a dog are the usual buyers.
It's the wrong move in three situations. First, if you mostly fly alone or with one passenger, you'll pay twin-cabin costs for empty seats. Second, if you want pressurization, look elsewhere, because the DA62 flies high on oxygen, not in a pressurized cabin. Third, don't count on seven adults: the third-row seats suit children or small adults, and full seats plus full tanks will usually exceed the weight limit. Run a weight and balance on your real missions before you shop.
Training: what changes between the DA42 and the DA62
| Requirement | Needed? | Notes |
|---|---|---|
| Multi-engine class rating | Already held | Carries over. No new practical test. |
| Complex endorsement | Already held | Both airplanes have retractable gear, flaps and FADEC-controlled propellers. |
| High-performance endorsement | No | Required only above 200 hp per engine. The AE330 is rated at 180 hp. |
| DA62 checkout | Yes | The underwriter sets the dual hours and any conditions; get this in writing before you buy. |
| Known-icing operations | If equipped | Learn the ice-protection system and its approval status for the specific airplane from the AFM supplement. |
The checkout focuses on the things that feel different, not the things that feel familiar:
- Weight and speed. The DA62 is heavier, with different V-speeds, including Vmc and Vyse, and it carries more energy on approach. Single-engine performance at high weight and density altitude needs the same respect it did in the DA42.
- Loading. With seven seats and a nose baggage area, center-of-gravity planning becomes a routine preflight task instead of an occasional one.
- Engines and systems. The AE330 works like the AE300 you know (FADEC, gearbox, Jet-A), but it has different power, limits and procedures. Model-year differences in avionics and equipment also matter. Train in the configuration you're buying.
- Coming from a DA42 L360. If your DA42 has avgas Lycomings, the diesel's fuel planning, engine-start routine and failure modes are all new. Budget extra dual time for them.
Insurance: what underwriters look at on the step to a DA62
Your DA42 time is the strongest thing you bring. Underwriters weigh total time, multi-engine time, retractable time and time in type, and a DA42 owner with several hundred multi hours presents very differently from a newly rated pilot. Two things still push the premium up. The hull value more than doubles, and the extra seats increase liability exposure, especially on policies with per-passenger sublimits. Expect a required checkout with an instructor experienced in the DA62 before you fly solo, and ask whether recurrent training earns a credit. The 2026 market is stable to softening for experienced piston owners, according to BWI and Gallagher. We have no verified 2026 DA62 premium benchmark, so this page's $9,500 figure is an assumption. Your lender will also require hull cover for at least the loan balance; see aircraft loan insurance requirements.
Cost delta: DA42 vs DA62
Every dollar figure below is a planning assumption, not a quote. The DA42 column matches our DA42 cost of ownership page and assumes Austro AE300 engines. Jet-A isn't in our verified price data, so both columns use an assumed $6.50/gal. Purchase prices are illustrative points for the math, not valuations. Verify values with Vref or Aircraft Bluebook, and confirm engine overhaul or exchange pricing with Austro Engine or a Diamond service center.
| Line item | DA42 NG / DA42-VI | DA62 |
|---|---|---|
| Illustrative purchase price | $420,000 | $950,000 |
| Fuel burn (planning, both engines) | 12 gph Jet-A | 16 gph Jet-A |
| Fuel per hour | $78.00 | $104.00 |
| Engine reserve per hour | $72.22 (2 × $65,000 ÷ 1,800 hr) | $83.33 (2 × $75,000 ÷ 1,800 hr) |
| Propeller reserve per hour | $8 | $8 |
| Unscheduled maintenance per hour | $40 | $50 |
| Insurance (assumption) | $6,500 | $9,500 |
| Annual inspection (assumption) | $5,000 | $7,000 |
| Total at 100 hours | $31,322 | $41,033 |
The operating gap, about $9,711 a year at 100 hours, is modest next to the jump in purchase price. That makes the DA62 decision mostly a capital decision: the loan, the down payment and the value you'll hold. Each $1/gal change in Jet-A moves the DA62's 100-hour fuel bill by $1,600. Diesel engine economics depend on the specific airplane: check each engine's time against Austro's published overhaul interval and any gearbox inspection requirements, and price the remaining time into your offer (see SMOH and TBO explained). Hangar costs rise too, because the DA62's wingspan and length won't fit every T-hangar that took your DA42.

Financing the step-up: DA42 equity, trade-ins and twin terms
The twin lending rules you already live with still apply. Per AOPA's piston financing page, multi-engine loans take 15% to 30% down depending on age, with maximum terms of 10 to 15 years. A DA62, built from 2015 onward, sits at the favorable end of the age scale. The new variable is size: the loan roughly doubles, so the payment does too. Rates as of September 2026 generally run from about 7% for well-qualified borrowers to roughly 10%; the table uses an illustrative 7.75%.
Worked example. Sell a $420,000 DA42 with a $200,000 payoff and 5% selling costs, and you clear $199,000. That is about 20.9% of a $950,000 DA62, which meets a common 20% minimum on its own.
| Loan | Amount | Term | Monthly |
|---|---|---|---|
| DA42 at 20% down (for comparison) | $336,000 | 15 years | $3,163 |
| DA62 at 20% down | $760,000 | 15 years | $7,154 |
| DA62 with all DA42 equity down | $751,000 | 15 years | $7,069 |
| Same loan, shorter term | $751,000 | 10 years | $9,013 |
| DA62 at 30% down | $665,000 | 15 years | $6,259 |
Sell or trade? Selling privately usually nets more. At an assumed dealer allowance of 92% of value ($386,400), a trade leaves $12,600 on the table compared with a private sale net of 5% costs. What the trade buys you is certainty: one closing, no period of owning two twins, and no second insurance policy. If you buy the DA62 before the DA42 sells, the lender counts both payments against your income, and the down payment must come from cash or a cash-out refinance of the DA42 (see using your airplane's equity). Either way, keep cash back for the checkout, the first-year premium and the first annual; down payment strategies covers the trade-offs.
Business use. If the DA62 will be used more than 50% for business, 100% bonus depreciation is permanent for eligible aircraft acquired after January 19, 2025, and the deduction can offset part of the cost of stepping up. Charter use changes the depreciation class. The rules turn on documented use, so confirm with a CPA or aviation tax adviser for your situation; see aircraft depreciation after the 2025 tax law.
Pre-buy checks specific to this move
- Engine and gearbox times on both AE330s against Austro's current limits, plus any service bulletins still open.
- Certified maximum takeoff weight. DA62s for some European markets were certified at 1,999 kg (4,407 lb) rather than the U.S. 2,300 kg (5,071 lb). On an imported airplane, confirm the weight, the paperwork and the U.S. airworthiness path; see importing an aircraft.
- Ice protection. What is installed, and whether the airplane is approved for known icing.
- Avionics generation and options, which affect value and what your insurer and appraiser see.
- Composite damage history, inspected by a Diamond-experienced shop; see the pre-buy inspection checklist.
How this guide differs from related pages
This page covers the DA42-to-DA62 transition: training, insurance, the cost gap and financing the step. For specifications and generated payment examples, see the DA42 and DA62 model pages. For the full DA42 annual budget, with hangar and 50/100/200-hour scenarios, see DA42 cost of ownership. If you haven't bought your first twin yet, start with SR20 to DA42. If you want more cabin without a second engine, compare DA40 to DA50. Lender documentation is listed in aircraft loan requirements, and term trade-offs are in choosing an aircraft loan term.
Frequently asked questions
Do I need a new rating or endorsement to fly a DA62 after a DA42?
No FAA rating or endorsement is new. You already hold the multi-engine rating and the complex endorsement the DA42 requires, and the DA62 does not need a high-performance endorsement because each Austro AE330 makes 180 hp, under the 200 hp threshold. What you do need is a DA62 checkout, and your insurer will set its length.
Is the Diamond DA62 pressurized?
No. The DA62 is an unpressurized, turbocharged diesel twin with a published service ceiling of 20,000 feet, so high-altitude flights use oxygen. Pilots who want a pressurized cabin at this budget usually look at older pressurized piston twins or single-engine pressurized aircraft instead, each with a very different maintenance profile.
How much more does a DA62 cost to operate than a DA42?
On this page's labeled assumptions, about $9,711 more a year at 100 hours before hangar and financing: $31,322 for a diesel DA42 against $41,033 for a DA62. Higher fuel burn, larger engine reserves, a bigger annual and a higher hull premium make up the gap. Jet-A prices vary, so use your own FBO price.
Can I use my DA42 equity as the DA62 down payment?
Yes, if you sell first. In this page's example, a $420,000 DA42 with a $200,000 payoff and 5% selling costs leaves $199,000, about 21% of a $950,000 DA62. Multi-engine loans typically take 15% to 30% down, so that equity alone can meet a common minimum.
What loan term can I get on a DA62?
AOPA's published guideline for multi-engine aircraft is a maximum term of 10 to 15 years, compared with up to 20 years for singles on loans of $75,000 or more. At an illustrative 7.75%, a $751,000 DA62 loan costs about $7,069 a month over 15 years and $9,013 over 10.
Should I trade my DA42 to a dealer or sell it privately?
A trade closes both deals at once and removes the risk of owning two twins, but the allowance is usually below a private sale. If a dealer offered 92% of a $420,000 value, you would receive $12,600 less than a private sale net of 5% costs. Decide whether speed and certainty are worth that.
