That Time Cessna Made a Helicopter

In the 1950s, Cessna acquired Seibel Helicopter Co. and began work on the CH-1 Skyhook.

Key Takeaways:

  • Cessna's only helicopter, the CH-1 Skyhook, was developed in the 1950s after acquiring Seibel Helicopter Co. and redesigning its S-4B model.
  • The CH-1 featured a modern design with a powerful supercharged engine, enabling record-breaking high-altitude performance such as landing on Pikes Peak and reaching nearly 30,000 feet.
  • Cessna targeted both military (as the YH-41 Seneca for the U.S. Army) and civilian markets for the CH-1, promoting its spacious cabin and panoramic visibility.
  • Despite its innovative features, the CH-1 program was ultimately discontinued due to significant issues with engine reliability (short TBO) and a high purchase price compared to competitors, leading to most units being scrapped.

If you’d like to stump everyone at aviation trivia, simply ask them to name the Cessna with the shortest takeoff-and-landing distances. More than likely, guesses would include the O-1 Birddog and possibly the 180 and 182. However, digging into the dustier corners of Cessna’s history reveals the true winner—its one and only helicopter the company ever produced, the CH-1 Skyhook.

The idea of introducing a helicopter to the Cessna product line began to gain traction in the early 1950s. This was a time when the company’s fixed-wing offerings were relatively modest but were on the brink of massive expansion. The lineup in the early part of the decade consisted of the 120/140, 170, 180, 190/195, O-1, and the 310/320 twins but by the following decade would more than double in size and encompass entirely new categories. A helicopter, Cessna thought, would be one more way to gain market share.
