What is the difference between a Citabria and a Decathlon?

Both are tailwheel-configured, fabric-covered, tandem-seating two-seat trainers from the same product line. The Citabria variants (7ECA Aurora, 7GCAA Adventure, 7GCBC Explorer) range from 118 hp to 150 hp and are certified in the Utility category for limited spin and intro-aerobatic training. The Decathlon 8KCAB (and Super Decathlon) carries a 180 hp Lycoming AEIO-360-H1B with inverted oil and fuel systems, certified in the Aerobatic category at ±6g for full unrestricted aerobatic training.

Why is the Decathlon used for intro-aerobatic training?

The Decathlon's combination of a fully-aerobatic-certified airframe, inverted oil and fuel systems, modest 180 hp output, and tandem two-seat configuration with dual sticks makes it the canonical entry-point intro-aerobatic and unusual-attitude airframe in the US fleet. IAC chapters and most US aerobatic schools standardise on the Super Decathlon for primary aerobatic instruction before students transition to higher-performance types like the Pitts S-2 or Extra 300.

Is the Citabria still being built?

Yes. American Champion Aircraft continues to build new Citabria, Decathlon, Super Decathlon, and Scout airframes at the Rochester, Wisconsin factory. Production volume is modest but continuous.

Can the Citabria be used for IFR training?

No. The Citabria and Decathlon are day-VFR airframes with limited panel space; the type is purpose-built for tailwheel and aerobatic training rather than IFR work. Students seeking instrument-rating instruction transition to a 172, PA-28-181 Archer, or DA40.

Why is the Citabria / Decathlon family popular?

Structured popularity-driver evidence. Each axis below carries one factual statement; we don't grade, the facts speak.

Regulatory fit

Aerobatic-category certification on the Decathlon / Super Decathlon (8KCAB, AEIO-360-H1B) at ±6g, plus tailwheel configuration across the line, makes the family the canonical US intro-aerobatic and tailwheel-endorsement trainer.

Industry network effects

The Decathlon / Super Decathlon dominates the US intro-aerobatic and spin-training market — IAC chapter operators, the Aviat / American Champion network, and the broader tailwheel-school ecosystem run the type at scale.

Pedagogy and handling

Tandem-seating tailwheel airframe with stick-and-rudder handling; the Citabria line is widely used as the entry-point tailwheel endorsement airframe before students transition to more demanding tailwheel types like the Cub, Husky, or Pitts.

Production volume

Approximately 5,500 Citabria / Decathlon / Scout airframes built across the production line since 1964; current production continues at American Champion Aircraft in Rochester, Wisconsin.

Before you buy more aircraft

The next airframe is rarely the highest-leverage move.

Flight school revenue is a function of three things — utilisation, dispatch reliability, and student progression — that multiply rather than add. Most schools running below 850 hours per aircraft per year have hidden capacity worth more than the next purchase, already paid for and sitting on the ramp.

How flight schools track this aircraft in Aviatize

Schools running Citabria / Decathlon fleets typically configure them in Aviatize as tailwheel and aerobatic training airframes. The tailwheel endorsement and aerobatic-category-pilot recency requirements are commonly modelled as per-pilot validation rules. Engine reserves track against the Lycoming AEIO-360 / O-320 / O-235 TBO; fabric inspection and re-cover cycles are tracked as separate maintenance items.
