Socata TB-9/TB-10/TB-20/TB-21/TB-200 Tampico/Tobago/Trinidad

The Socata TB family is a series of all-metal, low-wing, single-engine piston aircraft designed by the French manufacturer SOCATA (Société de Construction d'Avions de Tourisme et d'Affaires), a subsidiary of Aérospatiale/EADS, and now supported by Daher. The first prototype flew on 23 September 1977, with French DGAC type certification received 26 April 1979. The family was conceived as a modern replacement for the Rallye series and a European competitor to the Piper Cherokee and Beech Bonanza line.

The TBs are instantly recognizable for their distinctive "humpback" fuselage profile, gull-wing doors (opening upward like a sports car), and club-style seating that gives rear passengers genuine limousine-grade legroom — unusual in a piston single. The cabin is the widest in its class at 50 inches, and visibility from the low wing with bubble canopy is exceptional. Production ran from 1979 until approximately 2013 (with the main bulk wound down by 2006), totaling about 2,150 aircraft across all variants. The TBs have a loyal owner community, particularly strong in Europe, and the "Generation Two" or GT line introduced in early 2000 brought carbon-fiber cockpit roof modifications, improved interiors, and digitally-controlled turbocharging on the TB-21 GT.

Owners are typically step-up pilots moving from Cherokees or 172s who want genuine touring capability with European flair, or IFR-rated pilots looking for a four-place cross-country cruiser that costs less than a Bonanza. See cross-country and business-travel for mission fit.

The TB-11 was a planned variant that never entered production.

The factory TB-20 Trinidad numbers (159 KTAS at 75% at 8,000 ft) are often reported as optimistic; owner-reported cruise speeds cluster around 153–157 KTAS at ~13.5 GPH. The TB-21 GT is the standout performer — it genuinely turns in 190 KTAS at FL250 with a digitally-controlled turbo and oxygen. The airframe is aerodynamically clean for its class, though the fixed-gear TB-10/TB-200 pays a speed penalty for the spatted mains and non-retractable nose.

The TB-9 Tampico, with a fixed-pitch prop and 160 HP, is noticeably slower than a 172 at altitude despite the aerodynamic advantage — the fixed-pitch prop is the limiting factor. The TB-10 with constant-speed prop and 180 HP behaves much like an Archer in climb and cruise but with better cabin comfort.

High-density-altitude climb performance of all variants is modest; the TB-20's 1,260 fpm sea-level climb degrades significantly by 8,000 ft MSL. The TB-21 turbo is the correct answer for mountain/Western US operations.

Stall behavior is benign and the aircraft is stable in IMC — it's a genuinely pleasant IFR platform.

TB-20 Trinidad (useful load 1,111 lb, 86 gal / 516 lb usable fuel):

• Full fuel + 2 adults: 1,111 − 516 = 595 lb remaining. Two 190-lb adults fill this easily with ~215 lb for baggage. Range at 75%: ~1,050 NM with IFR reserves. The ideal "long cross-country with couple" scenario.
• Full seats (4 × 180 lb) + 50 lb baggage: 770 lb of payload leaves 341 lb for fuel = ~57 gal. Range drops to approximately 680–720 NM — still excellent for a 4-place.
• Five seats (club + third-row child): Rare configuration; the fifth seat is genuinely usable by children or a small adult. With five 150-lb occupants and 50 lb baggage (800 lb), fuel is limited to ~310 lb (~52 gal), range ~620 NM.

TB-10 Tobago (useful load ~992 lb, 54 gal / 324 lb usable fuel):

• Full fuel + 3 adults is achievable; four adults plus any baggage requires fuel reduction. Range with four adults and minimum fuel falls to 350–400 NM.

TB-21 Trinidad TC gains altitude capability but trades ~75 lb of useful load vs the TB-20 due to turbo installation weight. At FL200+, true airspeed and headwind mitigation can produce the best practical block times in the family.

The TB family's payload-range story is its strongest selling point: the Trinidad is one of the few piston singles that genuinely flies four adults 700+ NM in comfort, rivaling the Bonanza and outperforming the Mooney in cabin space if not raw speed.

• Cross-country (9/10): The TB-20/TB-21 are purpose-built tourers. 1,100 NM range, 1,111 lb useful load, club seating, and a 50-inch-wide cabin make them excellent for long legs with 3–4 adults. See cross-country.
• Business travel (8/10): Same strengths — fast enough, IFR-capable, comfortable. Downside vs a Bonanza is parts/support. See business-travel.
• Flight training (5/10): TB-9 and TB-10 were marketed as trainers and used heavily by European flight schools (ENAC, British Aerospace). In the US market they're less common as trainers because dispatch parts are slower than 172 parts. See flight-training.
• Local fun flying (6/10): Gull-wing doors and bubble canopy are genuinely fun; TBs have real "ramp appeal." But insurance on the retractable Trinidads penalizes low-time owners. See local-fun-flying.
• Cargo hauling (5/10): Decent useful load (1,111 lb on TB-20), but no cargo door and a small baggage area limit bulky loads.
• Backcountry (2/10): Low wing, retractable gear on the Trinidads, and modest prop clearance rule out rough strips.
• Aerobatics (1/10): Not certified; normal category only.
• Surveying (4/10): Low wing limits downward visibility; fine for photo-mapping with belly ports but not ideal for pipeline/powerline work.

• Early TB-9/TB-10 (1979–1990): Typically King KX155 nav/coms, KN53, KR87 ADF, steam gauges. Many now upgraded with Garmin GNS 430W or GTN 650 retrofits ($15–25k installed).
• TB-20 Trinidad (1984–1999): Factory panels came with Bendix/King IFR stacks. Owner upgrades commonly include GTN 750Xi, GFC 500 autopilot retrofit (where STC'd), and Aspen E5/Garmin G5 EFIS replacements.
• GT models (2000–2013): Factory Garmin panels became available — GNS 430/530 and later G500 integrations. Some late TB-20 GTs left the factory with Avidyne Entegra primary flight displays.
• TB-21 GT turbo: Often found with weather and traffic (Stormscope, Skywatch) reflecting the high-altitude IFR mission.

See avionics-pricing for retrofit costs.

The STC catalog for TBs is thinner than American types — a key ownership consideration. Notable options include:

• Garmin GFC 500 autopilot — STC'd for TB-20/TB-21 (approximately $28–35k installed). A significant value-add and safety upgrade replacing the aging KFC-150.
• Power Flow tuned exhaust — available for TB-9/TB-10 variants; adds 5–8 KTAS cruise and marginal climb improvement.
• Gross weight increases — some European TB-20s carry higher MTOW approvals unavailable on US certification.
• LED lighding / nav-strobe replacements — Whelen and AeroLEDs STCs available.
• Monroy long-range tanks — rarely needed given stock 86 gal capacity on the Trinidad.
• Aspen E5 / Garmin G5 / G3X — primary flight display retrofits, approved for TB family via AML STCs.

There are no widely-available engine upgrade STCs (e.g., no 280 HP IO-540 swap comparable to the Bonanza's).

Daher (ex-Socata) continues to support the TB fleet with factory parts, technical documentation, and service information, but parts availability is the defining ownership challenge relative to Cessna/Piper equivalents. Non-urgent parts often ship from France with 2–6 week lead times; AOG expediting is available but expensive.

Mechanic familiarity is the second major factor — while any A&P can work on the Lycoming engines, airframe-specific expertise (landing gear rigging, fuel system, door mechanisms) is concentrated at a handful of specialist shops. In the US, notable TB specialists exist in the Mid-Atlantic and Southwest. In Europe, maintenance ecosystems are well-developed.

Typical annual inspection costs: $2,500–$4,500 for a clean airframe; $5,500–$8,000 with discrepancies. Expensive recurring items include gear actuator overhauls, door strut replacement, and the fuel selector overhaul. Expect ownership costs comparable to a Mooney M20J/K but with longer parts lead times. See maintenance-ecosystem.

The TB-20 Trinidad market ranges roughly $141k–$370k per Controller.com 2025 listings, with typical mid-life, mid-panel examples around $175k–$210k. TB-9 Tampicos bottom out in the $55–95k range; TB-10 Tobagos sit $85k–$150k; TB-200 Tobago XL $110k–$175k. TB-21 Trinidad TCs command a $30–60k premium over comparable TB-20s due to turbo and altitude capability, and GT models carry another $40–75k premium over pre-GT equivalents.

Key valuation drivers:

• Engine time — IO-540 overhauls run $45–55k; TIO-540 turbo overhauls $55–70k. SMOH above 1,600 hours meaningfully depresses price.
• GT cabin vs pre-GT — The carbon-roof GT refresh is a clear market divider.
• Panel — A modern Garmin GTN/G500/GFC 500 panel can add $50–75k to asking price.
• European vs US registered — US N-registered examples with clean FAA logs bring a premium; French F- or German D- imports often discount 10–20% until paperwork is cleaned up.
• Hangar history — TBs show their age outdoors; paint and interior condition matter.

See valuation-methodology for framework.

• Fuel selector valve — Recurring AD on fuel selector inspection; the plastic detent components can wear causing mis-selection. Critical item at annual.
• Elevator trim cable — Corrosion and wear AD requires periodic inspection; replacement parts have historically been slow from Daher.
• Nose gear torque link (TB-20/TB-21) — Known wear point; expensive to replace, prone to shimmy if worn.
• Landing gear actuator seals (Trinidad) — Hydraulic system uses proprietary Socata components; leaks at annual are common after 2,000+ hours.
• Engine mounts — Lycoming IO-540 mount cracks typical of the family, inspection required.
• Gull-wing door gas struts — Non-safety but expensive and routinely replaced ($400–800/pair).
• Pre-buy red flags: Incomplete logs (TBs imported from Europe often have French records that aren't clean to FAA standards); corrosion under carpet near battery box; gear swing history; and any sign of belly strikes on retractables.

No ADs ground the fleet, but parts lead times from Daher remain the single biggest ownership headache. See maintenance-ecosystem.

Hull insurance for a $150k–$200k TB-20 averages around $2,100–$2,585 per year with $1M smooth liability per owner survey data. Low-time pilots transitioning into the Trinidad face higher rates due to retractable gear and 250 HP (complex + high-performance endorsements required). Insurers typically require:

• Private pilot with instrument rating (for TB-20/TB-21)
• Complex and high-performance endorsements
• 10–25 hours dual with a TB-qualified CFI for transitioning pilots
• Minimum total time of 200–400 hours depending on underwriter

The TB-9 and fixed-gear TB-10 insure more easily, closer to $1,400–$1,800/year on comparable hull values. The turbocharged TB-21 often commands a 10–15% hull premium due to repair costs. See insurance-underwriting.
