1966 Beechcraft 35-C33A Debonair: Low Total Time, Upgraded Engine, and Modern Avionics
The 1966 Beechcraft 35-C33A Debonair stands as a testament to Beechcraft’s commitment to producing reliable, high-performance aircraft that offer an exceptional balance of value and performance. This particular model, with its low total time and significant upgrades, exemplifies the brand’s dedication to quality and innovation.
History of the Beechcraft Debonair
Introduced in the early 1960s, the Beechcraft Debonair was developed as a more affordable and less complex alternative to the Bonanza series. The Debonair retained the Bonanza’s fundamental design elements but featured a straight tail and more straightforward avionics to appeal to a broader market. In 1966, Beechcraft introduced the C33A variant, which was equipped with a more powerful 285-horsepower Continental IO-520-B engine, enhancing its performance capabilities.

Beechcraft Company History
Founded in 1932 by Walter and Olive Ann Beech, Beechcraft has a rich history of producing a wide range of aircraft, from single-engine planes to twin-engine turboprops and military trainers. The company gained early acclaim with the Model 17 Staggerwing and solidified its reputation with the Bonanza series, known for its distinctive V-tail design. Over the decades, Beechcraft has maintained a reputation for quality, reliability, and value, establishing benchmarks in the aviation industry.
