Diamond Aircraft DA20-C1
Aircraft Manufacturer: Diamond Aircraft
Model: DA20-C1
About the Diamond Aircraft DA20-C1
The Diamond DA20-C1 holds the second-largest active fleet among the manufacturer's models, with more than 300 aircraft on the U.S. civil registry. The DA20-C1 accounts for about 22% of Diamond Aircraft's active registered fleet.
Across every U.S. registry record ever held for the DA20-C1, about 60% remain registered. More than 200 DA20-C1 airframes have been deregistered over the type's time on the books.
The DA20-C1 records about 12 accidents per 1,000 aircraft-years over the type's FAA-registration exposure. On the safety percentile, the DA20-C1 records a higher accident rate than about 90% of comparable types in its peer cohort of the same aircraft type, engine class, and seat range, where a higher percentile means a higher accident rate. Of the 70 recorded accidents for the DA20-C1, 5 were fatal.

Safety Analysis
Composition of NTSB accident records for this model in general-aviation operations (FAR Part 91 and 137), based on NTSB data as of May 1, 2026. It's a breakdown of recorded accidents rather than a safety rating, and types with significant non-GA operation (such as Part 135) may be under-represented.
Accidents are identity-confirmed against FAA registration records (two independent sources).
15 exact, 55 recovered, 0 provisional
MethodologyTotal recorded general-aviation accidents within the analyzed period.
5 fatal accidents.
7.1% of recorded accidents were fatal.

Aircraft-years of FAA registration exposure (2008–present).
Within its peer cohort
Within this model's peer class (same aircraft type, engine class, and seat range), comparison of its share of recorded NTSB accidents to its share of FAA registration exposure (aircraft-years since 2008).
This is a share comparison, not flight-hours adjusted, so a model flown more per airframe than its peers will show an accident share above its exposure share even if its per-hour safety is average. Methodology →
Accidents by year
Recorded NTSB general-aviation accidents per calendar year, derived directly from the NTSB accident database. Each bar shows the accidents that occurred in that year. Methodology →
Phase of flight
Which phase of flight each accident occurred in, as coded by the NTSB. Most accidents happen in the phases where most flying time is concentrated, so this isn't a measure of which phase is most dangerous.
Finding category
Top-level NTSB cause category, from the coded investigation findings. An accident often has more than one finding, so totals here can exceed the recorded accident count.
Injury severity
NTSB classification of the worst injury in each accident: None, Minor, Serious, or Fatal. Each accident counts in exactly one severity.
