Schweizer 330SP

The Schweizer 330SP is a versatile light utility helicopter produced by the Schweizer Aircraft Corporation, a company with roots dating back to 1939 in Elmira, New York. Introduced in the early 1990s as an upgraded version of the long‑standing 330 model, the 330SP incorporated a more powerful Lycoming T53‑17A engine, refined rotor system, and upgraded avionics, providing higher hover performance and better fuel efficiency. Its dual‑seat configuration, generous cargo area, and retractable landing gear made it popular for training, law‑enforcement, and aerial‑photography missions. The aircraft’s simple mechanical design, low operating costs, and ability to operate from unprepared sites contributed to its widespread adoption in both civilian and military roles worldwide. In addition, the 330SP served as the basis for the later 340 and 350 variants, establishing a lineage that influenced modern light helicopters such as the Sikorsky S‑333. By combining rugged reliability with flexible mission capability, the Schweizer 330SP helped cement Schweizer’s reputation as a leader in affordable, dependable rotary‑wing platforms, leaving a lasting imprint on general‑aviation helicopter training and operations. Today, several examples are still flying in private collections and flight schools, demonstrating the model’s enduring appeal.
