About the Beechcraft Twin Bonanza

The Beechcraft Twin Bonanza — the Model 50 — is a six-seat piston twin built from 1951 to 1963, larger and heavier than its single-engine Bonanza namesake. Powered by two Lycoming engines and notable for its wide cabin and rugged construction, it served civil and military operators (as the L-23 and U-8 Seminole) and was the design ancestor of the King Air line. The Beechcraft Twin Bonanza is now a vintage twin, valued for its roomy cabin and place in Beechcraft history.

Produced 1966–1985.
