About the Diamond DA40
The Diamond DA40 is one of the safest four-seat single-engine aircraft in production — composite construction, Austro AE300 diesel (modern variants) or Lycoming IO-360 (DA40-180 piston variant), factory Garmin G1000 NXi avionics, ~150 kt cruise on the diesel. The DA40's exceptional safety record (independent analyses consistently rank it among the safest small aircraft) combines with materially lower operating cost than Avgas equivalents (DA40 NG with diesel burns ~6-9 gph Jet-A vs ~10-12 gph Avgas on equivalent Cessna 172 or Cirrus SR20). Production variants: DA40 TDI (Thielert diesel, 2002-2008 — engine support issues), DA40 NG (Austro AE300 diesel, 2009+ — current), DA40-180 (Lycoming IO-360 piston, current). The DA40 NG with Austro AE300 is the volume modern fleet.

Buying a Used Diamond DA40
Every Diamond DA40 faces a mandatory 2,000-hour overhaul, so the single biggest factor in used price is how much time remains before that overhaul is due — a fresh-overhaul airframe can be worth a large share of the $25,000 overhaul cost more than one approaching its limit.
What to check before buying
- Time to overhaul — hours and years remaining to the 2,000-hour limit; this dominates resale value more than total time.
- Logbook completeness — continuous, gap-free maintenance records; missing logs cut value and complicate financing.
- Damage history — any prior accident, hard landing or blade strike; cross-check the registration against accident databases.
- Avionics — a glass panel vs steam gauges materially changes price.
- Pre-buy inspection — always commission an independent inspection by a type-experienced mechanic before money changes hands.
