Diamond does not publish a current price for the DA40 that we could find, so the best new-airplane reference is old: Plane and Pilot listed a 2007 DA40 XL at $339,695. A used DA40 NG, the diesel model, asks a median of $500,000 in our sample, and an older DA40-180 Star asks $240,000.
The DA40 is a composite four-seater, and the FAA register shows a fleet held mostly by companies and public bodies: LLCs and government owners hold 66.3% of the 1,018 aircraft. The used market splits along the engine, gasoline or diesel.
What follows looks at the used market, the family, who owns the fleet, what the airplane costs to run and what the NTSB accident files record. Every figure comes from a named public source or a dated sample, and the sources are listed at the end.
Data used: FAA fleet through 2026-10-12; NTSB file through 2026-09-30; asking-price sample 2026-10-14.
What a new DA40 costs: no number to quote
Diamond's current price list was not available to us, and the maker's tech specs page publishes no price. The most recent dated figure we could verify is Plane and Pilot's 2007 table, which lists the DA40 XL at $339,695. It is a reference from a different decade, not a quote. Ask a Diamond dealer for a current price with the equipment you want.
The FAA's type certificate data sheet covers the DA 40 from 2001 and the diesel DA 40 NG from 2011. The gasoline DA 40 has a Lycoming IO-360-M1A, a maximum takeoff weight of 2,535 lb and 40.2 US gal of usable fuel. The DA 40 NG has an Austro Engine E4 diesel, 2,822 lb maximum takeoff weight, which is 287 lb more, and 28 US gal of usable fuel.

The diesel carries the premium
We gathered 60 DA40 listings from one marketplace on 14 October 2026, and 35 of them carried a usable asking price. That is a small sample, and every figure below should be read as a snapshot.
Teal bars are medians of asking prices. Groups with fewer than 5 priced listings are left out. There is no current list price to show.
The NG asks a median of $500,000 on 15 listings, from $389,000 to $699,000, which is 2.1 times the DA40-180 Star's $240,000. The XL, XLS and XLT group asks $361,000 and the plain DA40 $264,000.
Split by build year the NG's price barely moves: the 2018 to 2021 group asks $492,000 and the 2022 to 2026 group $515,000. What changes is the airframe: the older group has flown 2,207.5 hours and the newer group 125.
A median 2022 to 2026 DA40 NG asks only $515,000 and has flown 125 hours.
One caution covers this whole section. It is one marketplace on one day, with 35 priced listings after we set aside 24 with no price and 1 placeholder price. These are asking prices, not sales, and no individual listing is published. Prices were recorded to the nearest 1,000 dollars. The diesel DA40 D has no priced listing.
For the wider market, our guide to what a small plane costs puts the DA40 in context, and what Diamond aircraft cost covers the maker. The twin is covered in what a Diamond DA42 costs and the smaller trainer in what a Diamond DA20 costs.

Gasoline and diesel on one airframe
The sheet lists three DA40 models: the DA 40, the DA 40 F and the diesel DA 40 NG. The marketing names that sellers use, such as XL, XLS, XLT and Star, are not separate headings on the sheet, so this page groups them by what sellers call them and not by certified model. For where the DA40 sits among the rest, the guide to the main types of planes helps.
- Lycoming IO-360-M1A
- 2,535 lb maximum takeoff weight
- 40.2 US gal usable fuel
- Lycoming O-360-A4M
- 2,535 lb maximum takeoff weight
- 40.2 US gal usable fuel
- Austro Engine E4
- 2,822 lb maximum takeoff weight
- 28 US gal usable fuel
The register splits the family into the DA40 label, with 688 aircraft (67.6%), and the DA40 NG, with 315 (30.9%). The sheet does not state horsepower for these models in the rows we could read, so this page prints none.

Built in two bursts
The FAA register lists 1,018 aircraft in the DA40 family, and 1,014 of them (99.6%) hold a valid registration, while 4 carry another status. Of the whole family, 938 records have a usable build year, and 935 of those are valid. That counts paperwork, not airplanes in the air: a valid registration says nothing about whether the aircraft is airworthy or flying.
- 5402000s
- 1252010s
- 2732020s
80 records have a blank or invalid build year and are left out of the chart.
The 2000s are the biggest decade, at 540. The 2010s dip to 125, and the 2020s have already recovered to 273, 148 more than the whole of the 2010s.
LLCs hold 55.4% of the register, corporations 14.2%, individuals 12.9% and government owners 10.9%. A government owner holding more than one in ten of a four-seat airplane is unusual, and the registry does not say why: the owner category records who holds the paper, not how the airplane is used.
California (10.1%), Utah (9.1%) and Indiana (8.9%) lead the state table, with Florida (8.0%) fourth. The state field is the registrant's address, not where the aircraft fly, and a school or an LLC with many aircraft can move a small state a long way.

The list price is only the entry fee
After the purchase the airplane wants fuel, an engine fund, an annual inspection, insurance and somewhere to sleep. Only some of those have a published number worth printing.
Fuel
The two engines burn very differently, and the figures come from different sources. Plane and Pilot's table for the 2007 DA40 XL gives 10 US gal/hour at 75 percent power. Diamond's own configuration data gives the DA40 NG 5.1 US gal/hour, which Diamond also states as 19.3 l/hour, at 60 percent power, and the XLT 8.2 US gal/hour, also stated as 31 lt/hour, at 65 percent. The power settings differ, so do not divide one by the other. The diesel's published figure is lower, though at a lower power setting, and diesel fuel has a different price from avgas, so price each with your own quotes.
Turn the burn into money with your own fuel price. At an example $6.00 a gallon, the 2007 XL burns $60.00 of fuel an hour. Those prices are examples chosen to show the arithmetic, not market data.
The engine
Lycoming's service instruction covers the IO-360-M1A in the gasoline DA 40. It allows 2,600 hours per engine for the first run after factory-new or factory-rebuilt delivery, 2,000 hours per engine after an overhaul and, separately, a limit of 12 calendar years. The instruction carries conditions, and the engine's history and configuration decide which line applies, so read it before relying on the headline. For the diesel E4 we could not retrieve the maker's overhaul interval, so we publish none. The engine is the line item that arrives all at once.
The rest
The FAA describes an annual inspection interval of 12 calendar months for ordinary US personal aircraft ownership. Insurance, hangar or tie-down fees, labour rates and loan terms depend too much on the owner, the airfield and the airplane for one published number to mean anything, so this page prints none. Add your own quotes and you have a budget that belongs to you. More on the wider costs of owning an aircraft sits in our ownership section.
Renting is the benchmark your own figure has to justify. Our guide to how much it costs to rent a Cessna 172 shows the other side of the ledger for a different airplane.

What the accident files record
Every entry in the NTSB files is a real event, and the counts are all this page claims to know about them. The NTSB lists 68 accidents involving DA40-family aircraft from 2000 through 2025. Of those, 15, or 22.1%, were fatal, and 26 people died in them.
- 2000
- 2005
- 2010
- 2015
- 2020
- 10
- 32025
Counts only. The NTSB does not record how many hours the family flew, so these bars are not rates.
The count was highest in 2023, at 10. The yearly numbers are small, the airplane has only existed since 2001, and the data holds no flying hours to divide by, so no trend should be read into them.
The first coded phase is the one attached to the first event in the NTSB's sequence for each accident. Accidents without a coded sequence, or with unmapped codes, sit in separate rows of the full table.
Landing leads by a distance, at 33.8% of accidents, with enroute at 16.2% and approach at 11.8%.
The NTSB's own findings point at machines slightly more often than people here. Of the 55 accidents with causal findings in its current coding, 81.8% involve aircraft issues and 74.5% involve personnel issues. An accident can carry several findings, so the shares overlap and do not add up to the whole.

What to take from the numbers
- Decide gasoline or diesel first. In our sample the median ask runs from $240,000 for the DA40-180 Star to $500,000 for the NG.
- Expect no current list price. The only dated new-price reference we have is $339,695 for a 2007 XL, so get a dealer quote for a new one.
- Treat an asking price as an opening line. These are what sellers want. The sample cannot see what buyers pay.
- Ask for engine time since overhaul, not only airframe hours. The airframe medians in our sample run from 790 for the NG to 2,934 for the XL group, and the engine's own history is a separate number.
- Do not read a valid registration as a clean bill of health. Status V is paperwork, not an inspection.
Questions buyers ask
How much does a new Diamond DA40 cost?
We could not find a current Diamond price list. Plane and Pilot's 2007 table listed the DA40 XL at $339,695. Ask a dealer for a current quote.
How much does a used Diamond DA40 cost?
In a one-day sample of asking prices on Controller.com, the median ask was $500,000 for a DA40 NG, $361,000 for an XL, XLS or XLT and $240,000 for a DA40-180 Star. Those are asking prices, not sales, and the sample is small.
How many Diamond DA40 aircraft are there?
The FAA register lists 1,018 aircraft in the DA40 family, 1,014 with a valid registration: 688 DA40 and 315 DA40 NG.
How many Diamond DA40 accidents has the NTSB recorded?
The NTSB files hold 68 accidents from 2000 through 2025, 15 of them fatal. These are counts, not rates, because flying hours by model are not published.
