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

This page's frontmatter describes the TB-20 Trinidad — the retractable-gear flagship of the family — with the other four models recorded in the Variants table below.

An unresolved structural issue, flagged rather than fixed this pass: the TB-9, TB-10 and TB-200 are FIXED-gear airplanes and the TB-20 and TB-21 are RETRACTABLE — docs/CATALOG-SPLITTING-RULE.md Step 1 forces a split on gear type alone, no judgment call involved, and this page does not have one. See "What was wrong with this page before" and the certificate's raw passage for the reasoning; a proper fix needs its own dedicated performance sourcing for the fixed-gear trio, which this session did not do.

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 Flying and Business Travel for mission fit.

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

On the gear-type split this page still owes: TCDS A51EU's own Section II describes the TB-10 as "Similar to the TB 20 but with fixed gear" — the certificate itself treats gear type as the defining difference between these airplanes, which is exactly what docs/CATALOG-SPLITTING-RULE.md Step 1 already says forces separate pages. Recorded here rather than executed; see Overview.

163 KTAS at 65% power, 8,000 ft is this page's stored cruise reference — the SOCATA POH's own printed worked example on its cruise performance chart (Figure 5.14), matched to the fuel-flow table's 65% row (14.0 GPH) and the endurance table's 65% row (5h32' with reserves) at the identical setting. The derived range is 903 nm — see the derived: block for the arithmetic.

This replaces an unmatched triple. The prior page's 159 KTAS / 13.5 GPH / 1,100 nm did not come from one row of one table at one setting — no document found this session publishes 159 KTAS or 13.5 GPH at any stated power, and pairing an unstated cruise speed with an unstated-setting range is the exact mismatch runbook rule 3 exists to catch. A 2000 SOCATA sales brochure separately quotes "Maximum speed – 8,500 ft: 163 KTAS" and "Economical cruising speed: 157 KTAS" with no stated power setting for either, and a "Max. Range" of 1,108 nm not obviously tied to either speed — used here only as a cross-check (163 is a striking match to the POH's 65%-power figure), not as the primary source, because the brochure never says which speed its range figure describes.

Owner-reported cruise speeds in the field cluster somewhat below the factory figure, which is common and not itself evidence of anything wrong with either number — a 65%-power book figure describes a specific leaned, rigged, clean-airframe condition few owners fly to exactly.

The TB-21 GT is the standout performer at altitude — genuinely quicker in the 180s (KTAS) with a digitally-controlled turbo and oxygen, not independently re-sourced this session. The fixed-gear TB-10/TB-200 pay 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.

1,200 fpm sea-level climb at max weight (SOCATA brochure, replacing the uncited 1,260) degrades with altitude as on any normally aspirated single; 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 1,322 lb, 86.2 gal / 517 lb usable fuel):

• Full fuel + 2 adults: 1,322 − 517 = 805 lb remaining. Two 190-lb adults fill this easily with ~425 lb for baggage — well above the 143 lb structural baggage limit, so baggage compartment volume/weight limit binds before useful load does. Derived range at the stored 65%-power setting: 903 nm.
• Full seats (4 × 180 lb) + 50 lb baggage: 770 lb of payload leaves 552 lb for fuel = under the 517 lb max fuel weight, so this load can be flown with full fuel — a real improvement over the airplane's previous (uncited, lighter useful-load) description.
• Fifth seat (option 502): Rare in practice — few TB-20s carry the rear three-belt option, and it is CG- and weight-limited per TCDS Note 5, not a routine configuration.

TB-10 Tobago (useful load ~992 lb, 54 gal / 324 lb usable fuel — not re-sourced this session):

• 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 some useful load vs the TB-20 due to turbo installation weight (not independently re-sourced this session). 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 with full fuel 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. A derived 903 nm range, 1,322 lb useful load, club seating, and a 50-inch-wide cabin make them excellent for long legs with 3–4 adults. See Cross-Country Flying.
• 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 (1,322 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 Reference 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.

Not re-researched this session — carried forward unchanged from the prior pass and still uncited. 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. A follow-up pass should source this section the way beech-a36-bonanza's was sourced — Vref/Bluebook first, dated Controller asking prices second.

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 Aircraft 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 GA Insurance Underwriting.
