About the Beech 58 Baron

The Beechcraft Baron 58 is one of general aviation's most successful light twins, combining the comfort and speed of a cabin-class aircraft with the reliability of proven Continental IO-520 engines. Introduced in 1970 as an evolution of the original Baron 55, the 58 stretched the fuselage by ten inches, added a sixth seat, and became the definitive model in a line that has remained in continuous production for over five decades. Its distinctive V-tail-less design, roomy cabin, and 200-knot cruise speed made it a favorite among owner-pilots, air-taxi operators, and flight schools teaching multi-engine ratings.

The Baron 58 occupies a sweet spot in the piston-twin market: faster and more capable than a Piper Seneca, more affordable and easier to maintain than a pressurized Cessna 340, and rugged enough for charter work in remote regions. With a service ceiling around 19,000 feet and a range exceeding 1,000 nautical miles, it handles short hops and cross-country missions with equal competence. Thousands remain active worldwide, testament to Beechcraft's engineering and the type's enduring appeal.
