About the Diamond DA42
The Diamond DA42 Twin Star is the modern composite twin that replaced legacy piston twins as the volume multi-engine trainer and light family twin. Twin Austro AE300 diesel engines (modern fleet) or Thielert TAE 125 diesels (early fleet — see warnings below), ~170 kt cruise, factory Garmin G1000 NXi avionics, four-seat composite cabin. The DA42's combination of twin- engine redundancy, Jet-A operating economics and modern systems made it the multi-engine training benchmark and the light-twin family hauler at materially lower operating cost than legacy Avgas-powered piston twins. Production variants: DA42 (Thielert TAE 125, 2004-2008 — significant engine issues), DA42 NG (Austro AE300, 2009-2013), DA42 VI (Austro AE300 refined, 2013-current).

Buying a Used Diamond DA42
Every Diamond DA42 faces a mandatory 1,800-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 $28,000 overhaul cost more than one approaching its limit.
What to check before buying
- Time to overhaul — hours and years remaining to the 1,800-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.
