About Diamond Aircraft Company
Diamond Aircraft Industries is an Austrian-Canadian aerospace company that produces a distinctive line of composite-construction general aviation aircraft. The Diamond design language is consistent across the line: composite airframes, T-tails, sliding-canopy or gull-wing cabin access, modern Austro AE-series diesel engines burning Jet-A fuel, and factory Garmin glass cockpits. Diamond's safety record is class-leading — independent analyses consistently rank Diamond models among the safest small aircraft in production. The Austro AE diesel engines burn Jet-A at ~6-9 gph (DA40 single) to ~16 gph (DA62 twin), making operating cost materially lower than Avgas equivalents while delivering excellent reliability with proper maintenance. There are currently 271 used Diamond aircraft for sale.

Frequently Asked Questions — Diamond
Are Diamond DA62 diesel engines reliable?
The Diamond DA62 uses Austro AE330 diesel engines burning Jet-A fuel, and reliability is a real concern for buyers. Roughly 50% of used DA62s on the market have had at least one engine replacement. A recent AD addressed a manufacturing defect that caused widespread engine replacements. TBO is currently 1,000 hours (short for an aircraft costing $1.4M+), though overhauls run about $25,000 each. Some owners report the Austro engines are comparable to Continental/Lycoming reliability; others cite the 1,000-hour TBO as the biggest drawback. Always check engine history carefully.
Diamond DA40 vs Cessna 172 — which is the better trainer?
The Diamond DA40 is a modern composite low-wing design with a glass cockpit (Garmin G1000) standard, offering better visibility, a stick instead of yoke, and either Lycoming avgas or Austro diesel engine options. The Cessna 172 has conventional metal construction, decades of proven reliability, and the largest support network in aviation. The DA40 diesel version burns Jet-A at lower cost per hour, but the diesel engines are more complex. Flight schools increasingly choose Diamond for modern training; private buyers often prefer the 172 for simplicity and resale value.
How much does a Diamond DA62 cost to fly per hour?
The Diamond DA62 costs approximately $200 per hour in direct operating costs (fuel, maintenance, engine reserves), with total costs reaching $818/hour when including fixed costs at 200 hours/year. The fuel efficiency advantage is significant: the DA62 burns only 14.8 GPH total on Jet-A, compared to 16.5 GPH of avgas for a turbonormalized Bonanza A36 — and Jet-A typically costs less than avgas. However, the short 1,000-hour engine TBO and $25,000 overhaul cost per engine are important budget factors.
Is Diamond Aircraft a good brand?
Diamond Aircraft (headquartered in Austria with a factory in London, Ontario) has built a strong reputation for modern, efficient, composite aircraft. The DA40 and DA42 are widely used in flight schools worldwide. The DA62 twin is praised for its fuel efficiency, modern avionics, and comfortable cabin. Concerns center on the diesel engine reliability history and relatively small service network compared to Cessna or Piper. On AeroGurus, Diamond listings range from $107,000 for a DA20-C1 trainer to $1.75 million for a DA62 twin.
