Aircraft Manufacturer: Aeronca
Model: 11AC
About the Aeronca 11AC
The Aeronca 11AC holds the second-largest active fleet in Aeronca's lineup. More than 600 of the type remain on the active U.S. civil registry, accounting for about 15% of the manufacturer's active registered fleet. Across all U.S. registry records ever held for the 11AC, about two-thirds have been deregistered.
Recorded safety history for the 11AC covers 33 accidents over the type's FAA-registration exposure, an accident rate of about 2.3 per 1,000 aircraft-years. Of those 33 recorded accidents, 2 were fatal. On the safety percentile, the 11AC sits at about one in ten within its cohort of same type, engine class, and seat range, where a higher percentile means a higher accident rate; at about one in ten, the 11AC has a lower accident rate than most types in that cohort.

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).
32 exact, 1 recovered, 0 provisional
MethodologyTotal recorded general-aviation accidents within the analyzed period.

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.
Operating-rule mix (all parts): 091 (33)
