About the STINSON 108-3

The Stinson 108-3 is a storied model in the realm of general aviation, renowned for its reliability, versatility, and classic design. The Stinson 108 series itself was born out of the aviation boom following World War II. As soldiers returned and the concept of private flying gained popularity, the call for rugged, dependable, and user-friendly general aviation aircraft grew louder. This environment gave birth to the Stinson 108-3, which emerged as an enduring symbol of post-war civilian aviation boom.\n\nThe Stinson Aircraft Company, founded by aviator Edward 'Eddie' Stinson, was already well-established in the aviation world by the time the 108 series was launched. The 108-3 variant was introduced as part of an effort to further improve the balance between performance, comfort, and accessibility. Production of the Stinson 108-3 took place from 1947 to 1948, a brief but impactful period.\n\nOne of the notable improvements in the 108-3 model was the increased gross weight capacity. The aircraft featured a more powerful 150-horsepower Franklin 6A4-150-B3 engine. The gross weight was upped to 2,400 pounds, which allowed for greater payload and extended range. The 108-3 was also equipped with a spacious cabin, capable of accommodating four adults comfortably. This made it an excellent choice for both private pilots and small-scale commercial operators who needed an aircraft that could handle a variety of missions, from short trips to longer cross-country flights.\n\nThe utility and reliability of the Stinson 108-3 solidified its place in general aviation history. It was particularly favored for its good handling characteristics and robust construction, making it relatively easy to fly and maintain. The charming design, featuring a high-wing configuration, contributed to excellent visibility and inherent stability, which were critical for both novice and experienced pilots.\n\nDespite its short production run, the Stinson 108-3 remains a beloved aircraft among vintage aviation enthusiasts and continues to be a common sight at airshows and in aircraft collections. It stands as a testament to the period's engineering ingenuity and the broader historical era of aviation expansion and innovation.
