SOCATA TB 21 Trinidad TC — Primary-Source Technical Library
The SOCATA TB 21 Trinidad TC is the turbocharged, high-performance variant of the "Caribbean" series — a four-to-five-seat low-wing single-engine aircraft engineered at Tarbes for serious cross-country and IFR operations. This collection delivers the complete factory documentation set as issued by EADS/Socata and Aérospatiale Matra, covering maintenance, parts, and electrical systems across 14 archival volumes.
Aircraft Overview
Powered by a single Avco Lycoming TIO-540-AB1AD six-cylinder turbocharged engine producing 250 hp (186 kW) at all certified altitudes, the TB 21 was designed for efficiency and structural integrity. Its airframe uses advanced sheet aluminium alloy panel bonding — eliminating spot welding — and rigid push-pull control rods on all three primary flight surfaces. The pressurised cabin cross-section reaches 49–50 inches shoulder width, and the trailing-link main undercarriage absorbs hard landings with precision.

Regulatory & Airworthiness Context
The TB 21 is certificated under EASA TCDS No. EASA.A.378 (originally French DGAC/Aérospatiale). Active operators must use current revision-controlled data from the Type Certificate holder. Notable engineering interventions include FAA Advisory Circular AC 98-18-13 and Lycoming crankcase/crankshaft directives applicable to the TIO-540 series.
⚠️ Regulatory Notice: Under FAA 14 CFR § 43.13 and EASA Part-M, any mechanic performing maintenance on an active aircraft must use current, manufacturer-approved revision-controlled data. This archival document does not satisfy that requirement.
This is an archival, static-copy edition fixed at its original publication date. Intended for historical reference, flight simulation, museum restoration, and educational use only. Not approved for active airworthiness maintenance under FAA 14 CFR § 43.13, EASA Part-M, or equivalent international regulations. Operators of active aircraft must use current, revision-controlled publications from the Type Certificate holder or an authorized distributor.
