About the Beech 24 Sierra

The Beechcraft Sierra is a four-seat, single-engine piston aircraft that emerged in the late 1960s as Beechcraft's answer to the Piper Arrow and Cessna Cardinal RG. Introduced in 1970 as the Model 24R Sierra, it featured retractable landing gear and a 200-horsepower Lycoming IO-360 engine, offering owner-pilots a step up from fixed-gear trainers with cruise speeds around 145 knots. Beechcraft also produced the fixed-gear Sundowner variant (Model 23) on the same airframe, creating a family of rugged, stable cross-country tourers known for their solid build quality and docile handling characteristics.

The Sierra's claim to fame was its combination of Beechcraft's trademark heavy, stable feel with relatively forgiving stall behavior and a roomy cabin, wider than contemporary Pipers and more comfortable for long flights. Production ran until 1983, with approximately 700 Sierras built alongside several thousand Sundowners and Musketeers in the Model 19/23/24 family. While never a blockbuster seller like the Bonanza, the Sierra carved out a loyal following among pilots who valued its honest flying qualities and the prestige of the Beechcraft name without the complexity or cost of a Bonanza.

Today the Sierra remains a capable if somewhat overlooked platform in the used aircraft market, prized by owners who appreciate its 800-nautical-mile range, generous useful load, and straightforward systems. Its operating envelope (never-exceed speed of 225 knots indicated, cruise at 145 knots true, and a stall speed around 60 knots with full flaps) makes it a solid instrument platform and cross-country traveler.
