About the Beechcraft 58T

The Beechcraft Baron 58T is the turbocharged variant of the venerable Baron 58, one of general aviation's most successful light twins. Introduced in the mid-1970s, the 58T added twin Continental TSIO-520 engines with turbochargers, enabling the aircraft to maintain sea-level power up to higher altitudes and cruise efficiently in the flight levels where most light twins struggle. This capability made it particularly popular with owner-pilots flying long cross-country missions over mountainous terrain and with small charter operators needing reliable IFR performance.

The Baron 58T's pressurized cousin, the Baron 58P, offered even greater high-altitude capability, but the unpressurized 58T struck an appealing balance: it delivered much of the altitude performance without the complexity, weight, and maintenance burden of a pressurization system. Typical cruise speeds reach 200-220 knots true airspeed at altitude, with a service ceiling around 25,000 feet, substantially higher than naturally aspirated twins. The type seats six in a comfortable cabin and remains a favorite among business owners, ranchers covering large territories, and pilots who value the redundancy of twin engines combined with respectable speed and range.

Beechcraft built the Baron series for over four decades, and the 58T variant remains a common sight at general aviation airports across North America. Its combination of speed, payload, and high-altitude capability continues to serve operators who need more than a single-engine aircraft can offer but don't require the operating costs of a turboprop or light jet. SkyMeter has tracked flights across airframes and operators, with the largest observed operator.
