Bellanca Citabria / Decathlon (family)
Citabria 7GCAA: Lycoming O-320-A2B 150 hp; Decathlon 8KCAB: Lycoming AEIO-360-H1B 180 hp
The Bellanca Citabria 7GCAA and Decathlon 8KCAB are the airplanes that defined competitive aerobatic training for decades. The 7GCAA Citabria uses a 150 hp Lycoming O-320 and handles loops, rolls, and basic aerobatic work. The Decathlon 8KCAB uses a 180 hp AEIO-360 with full inverted fuel and oil systems and handles serious competition aerobatics. Both are fabric-covered tandem two-seaters built on the original Champion airframe family.
The Citabria and Decathlon naming gets complicated because the type certificates have moved between manufacturers (Champion, Bellanca, American Champion) and the variant codes describe specific configurations. This page treats the Bellanca-built and Bellanca-era 7GCAA and 8KCAB as a family, with notes on how they differ from the American Champion 7ECA covered separately. It also covers what owning either airplane actually costs in 2026 and the aerobatic-specific concerns that go with both.
History
The Citabria type certificate originated with Champion Aircraft in 1964 and moved to Bellanca in 1970 when Bellanca acquired the Champion line. Bellanca produced Citabrias and Decathlons through the 1970s and into the 1980s. The 7GCAA Citabria represented the utility and light aerobatic variant with the 150 hp Lycoming O-320. The Decathlon 8KCAB launched in 1970 specifically for serious aerobatic training, adding the AEIO-360 fuel-injected engine with inverted fuel and oil systems.
Bellanca went through financial difficulties in the early 1980s and stopped Citabria and Decathlon production in 1981. The type certificate eventually went to American Champion Aircraft in 1989, which has continued production of various Citabria and Decathlon variants from Rochester, Wisconsin. Bellanca-era airplanes remain the largest pool of used Citabria and Decathlon inventory.
The Decathlon in particular built a strong reputation in IAC competition and aerobatic instruction. The combination of 180 hp, full aerobatic envelope including inverted flight, and tandem layout made the airplane the dominant aerobatic trainer for decades. Many current acro pilots learned the maneuvers in a Decathlon. The 7GCAA Citabria served as the intermediate step up from the 7ECA for pilots wanting more performance without the Decathlon's full aerobatic capability.
Variants
7GCAA Citabria (150 hp)
1965-1981 BellancaUtility and light aerobatic variant. Rated +5/-2 g, approved for loops, rolls, and spins but not inverted flight. Better climb and cruise than the 115 hp 7ECA.
8KCAB Decathlon (180 hp)
1970-1981 BellancaFull aerobatic variant. Rated +6/-5 g, approved for inverted flight and sustained inverted operations. The serious aerobatic training airplane.
Super Decathlon 8KCAB-180
American Champion era, 1990-presentRefined post-Bellanca production. Updated wing fittings, improved cooling, current-production support. Higher acquisition cost but better long-term ownership profile.
Performance
The 7GCAA Citabria cruises at 115 to 125 KTAS at 65% power, burning 8.5 gph. The Decathlon 8KCAB is slightly slower at 110 to 120 KTAS because of the additional aerobatic gear, burning 9 to 11 gph at cruise. Climb performance favors the Decathlon at sea level (1,000-plus fpm) and altitude. Both airplanes are happiest at moderate cruise power settings.
Useful load is tight on both variants. The 7GCAA typically has 450 to 500 pounds of useful load. The Decathlon has 380 to 430 pounds because the AEIO-360 and aerobatic systems add weight. Full fuel on either runs 35 to 40 gallons depending on tank configuration. Two adults plus modest gear works on the 7GCAA. The Decathlon is functionally a one-passenger airplane for any real trip.
The Decathlon's aerobatic envelope is its differentiator. Rated +6/-5 g with sustained inverted flight capability, the airplane handles intermediate-level IAC sequences and serves as a teaching platform for serious aerobatic students. The 7GCAA's +5/-2 g rating is enough for basic aerobatic work but won't sustain inverted flight or negative-g maneuvers safely.
Powerplant
The 7GCAA Citabria uses the Lycoming O-320-A2B (150 hp, carbureted). Lycoming's published TBO for the O-320 is 2,000 hours per Lycoming Service Instruction 1009 BE. The O-320 is among the most-overhauled and best-supported engines in general aviation. Field overhaul runs $25,000 to $38,000 in 2026.
The Decathlon uses the Lycoming AEIO-360-H1B (180 hp, fuel injected, inverted fuel and oil). The AEIO designation reflects aerobatic certification with inverted-system capability. Published TBO is 2,000 hours per Lycoming SI 1009 BE, but the aerobatic-stress operating profile typically results in actual overhauls between 1,500 and 1,800 hours. Field overhaul of an AEIO-360 runs $35,000 to $48,000 in 2026, higher than a standard IO-360 because of the inverted-system components and increased shop scrutiny on aerobatic-flown engines.
Propeller varies by variant. The 7GCAA typically runs a fixed-pitch metal Sensenich, which is essentially zero-maintenance on a calendar basis. The Decathlon runs a Hartzell HC-C2YR-1 two-blade constant-speed prop with a 2,400-hour or six-year overhaul cycle per Hartzell Service Letter HC-SL-61-61Y Rev 12. Decathlon prop overhaul runs $3,500 to $5,500 in 2026.
Cost of ownership
Operating economics differ meaningfully between the 7GCAA Citabria and the Decathlon, primarily because of fuel burn and engine differences.
7GCAA Citabria: fuel runs $45 to $60 per hour at $5.50 to $7 per gallon and 8.5 gph. Engine reserve is $12 to $19 per hour. Prop reserve is under $1 per hour with fixed-pitch. Airframe maintenance reserve is $12 to $22 per hour, dominated by fabric work. All-in at 100 hours a year runs $80 to $120 per hour, plus $3,500 to $6,500 in annual fixed costs.
Decathlon 8KCAB: fuel runs $50 to $75 per hour at 9 to 11 gph. Engine reserve is $18 to $27 per hour (higher because of AEIO-360 overhaul cost and accelerated wear). Prop reserve is $1 to $3 per hour. Airframe maintenance reserve is $15 to $25 per hour because aerobatic stress accelerates wear. All-in at 100 hours a year runs $100 to $145 per hour, plus $4,500 to $8,000 in annual fixed costs.
Fabric re-cover dominates calendar cost on both variants. A complete re-cover runs $25,000 to $42,000 in 2026 and is typically needed every 15 to 25 years. Aerobatic-flown airplanes accumulate fabric stress faster than utility-flown airplanes, so the high end of that range is realistic for serious aerobatic use.
Acquisition cost in mid-2026 runs $50,000 to $80,000 for a 7GCAA Citabria with original fabric and modest avionics, $80,000 to $130,000 for a clean Decathlon with recent fabric. American Champion-built Super Decathlons trade at $130,000 to $200,000 with low time and modern panels. Factory new Super Decathlon from American Champion lists around $260,000.
| Fixed cost | Range | Frequency |
|---|---|---|
| Hangar Fabric airplanes benefit significantly from hangar storage. | $150–$400 | monthly |
| Annual inspection (Citabria) | $1,500–$2,800 | annual |
| Annual inspection (Decathlon, aerobatic use) Aerobatic-flown airplanes need more thorough inspection. Verify spar, gear, and engine mount condition. | $2,000–$3,800 | annual |
| Insurance (Decathlon, aerobatic use) Aerobatic insurance is materially higher than utility insurance on the same airframe. | $2,500–$5,000 | annual |

Common issues & gotchas
Aerobatic stress and structural fatigue (Decathlon)
highDecathlons flown aerobatically accumulate fatigue on the wing spar, attach hardware, engine mount, and tail surfaces. Pre-buy on a Decathlon should include dye penetrant inspection of critical welded joints, careful review of operating profile, and detailed logbook examination for hard landing or g-overage events.
Fabric condition and re-cover history
highFabric is the dominant pre-buy item on any Citabria or Decathlon. Verify last re-cover date and process used. Aerobatic-flown airplanes accumulate fabric stress faster than utility-flown airplanes. Look for soft spots, seam separation, and signs of internal moisture damage.
Wing spar and lift attach
highAmerican Champion has issued service bulletins covering wing spar and lift attach hardware on the Citabria family. Verify SB compliance and look for corrosion at strut attach points. Spar issues are serious safety concerns on any aerobatic-rated airframe.
AEIO-360 engine condition (Decathlon)
moderateThe AEIO-360 in aerobatic service typically reaches top overhaul earlier than utility-flown IO-360s. Compression checks, borescope inspection, and oil analysis should be standard pre-buy work. Verify inverted system function (fuel pump, oil scavenge) during the test flight.
Gear leg fatigue and tailwheel attach
moderateSteel tube gear and tailwheel attach accumulate fatigue from landing stresses, especially on aerobatic-flown airplanes that may have absorbed harder landings. Inspect welds for cracks and verify all hardware torque values.
Documentation gaps and logbook accuracy
moderateBellanca-era airplanes have changed hands many times. Logbook gaps, undocumented modifications, and incomplete AD compliance are common. Pre-buy should verify FAA registration matches actual airplane configuration and that all engine work, fabric work, and major repairs are properly documented.
Who it's for
Good fit for
- ✓ Aerobatic students and instructors (Decathlon)
- ✓ Pilots wanting more performance than a 7ECA without paying Super Decathlon prices (7GCAA)
- ✓ Owners willing to budget for fabric work and aerobatic-stress inspection
- ✓ Tailwheel pilots who want a step up from the 7ECA Citabria
- ✓ Buyers who can find aerobatic-knowledgeable mechanics and inspectors
Less good for
- ✗ Cross-country pilots prioritizing speed or range
- ✗ Two-up pilots carrying significant baggage
- ✗ Anyone storing the airplane outside long-term
- ✗ Buyers wanting modern cockpit ergonomics
- ✗ Pilots without tailwheel experience
The verdict
The 7GCAA Citabria is the intermediate step up from the 7ECA: more performance, similar handling, similar maintenance demands, and the option of light aerobatic flying. For a tailwheel pilot wanting more capability without paying Decathlon prices, the 7GCAA delivers.
The Decathlon is the serious aerobatic trainer. For pilots committed to learning competition aerobatics or teaching them, very little else in the certified market does what the Decathlon does at the same acquisition cost. But the Decathlon demands more on maintenance, more on insurance, and more on pilot proficiency than a utility airplane. Buyers who go in expecting an aerobatic specialist will be happy. Buyers expecting a casual recreational airplane will be unhappy with the operating cost and demands.

Frequently asked
How much does a used Citabria or Decathlon cost in 2026? +
7GCAA Citabria with original fabric runs $50,000 to $80,000. A clean Decathlon with recent fabric runs $80,000 to $130,000. American Champion Super Decathlons with modern panels run $130,000 to $200,000. Factory new Super Decathlon from American Champion lists around $260,000.
What's the difference between a Citabria 7GCAA and a Decathlon 8KCAB? +
The 7GCAA has a 150 hp carbureted O-320 and is rated +5/-2 g for light aerobatic work (loops, rolls, spins, but no inverted flight). The 8KCAB Decathlon has a 180 hp fuel-injected AEIO-360 with inverted fuel and oil systems and is rated +6/-5 g for full aerobatic flight including sustained inverted operations. The Decathlon is the serious aerobatic trainer.
Should I buy a Bellanca-era or American Champion Decathlon? +
Bellanca-era airplanes (1970s and early 1980s) are meaningfully cheaper to acquire and have a large used inventory. American Champion (post-1990) airplanes have improved construction, updated wing fittings, and current factory support. For pilots committed to long-term ownership and aerobatic use, American Champion is worth the premium. For pilots wanting an entry into Decathlon ownership, Bellanca-era airplanes deliver the same flying experience at lower cost.
Is the Decathlon a good competition aerobatic airplane? +
It's competitive in IAC Sportsman category and capable in Intermediate. Beyond Intermediate, dedicated aerobatic airplanes (Pitts, Extra, Sukhoi) outperform the Decathlon meaningfully. For pilots learning aerobatics or competing through Intermediate, the Decathlon is an excellent platform. For pilots competing at Advanced or Unlimited level, a purpose-built aerobatic airplane is essential.
How often does the fabric need re-cover? +
Fabric typically lasts 15 to 25 years depending on hangar storage and aerobatic use frequency. Hangared utility airplanes can stretch to 25-plus years. Outdoor-stored aerobatic airplanes may need re-cover in 12 to 15 years. Plan $25,000 to $42,000 for a complete professional re-cover when due.
Can I use a Decathlon for cross-country? +
Marginally. The Decathlon cruises at 110 to 120 KTAS and has tight useful load (380 to 430 pounds). Two adults with bags don't fit. Most owners fly the Decathlon for aerobatics and short local cross-country and use a different airplane for serious traveling. The 7GCAA Citabria with its lighter aerobatic systems is slightly better for two-up cross-country but still limited by its 35 to 40 gallon fuel capacity and modest cruise speed.
