Climb performance, always the primary beneficiary of any power increase, improved by 500 fpm to 1,400 fpm at sea level. The performance benefits of adding 55% more horsepower were immediate and predictable. The SR22 also was an all-electric airplane, without a vacuum system. Wingspan was increased 1.5 feet per side, adding 10 square feet of surface area, the better to lift 3,400 pounds of gross, 400 pounds more than the SR20. The fuselage was the same, although the nose was pushed forward to accommodate the larger engine. The Cirrus SR22 was a logical next step, a 310-hp Continental IO-550N-powered version of the original design. It took three years and roughly $70 million for the airplane to be certified, but the SR20 was finally ceremonially granted its FAA type certificate during the 1998 AOPA Convention in Palm Springs, Calif.įor all of those reasons, both the Klapmeiers elected to concentrate instead on a horsepower makeover. First flown in March 1995, it used a six-cylinder, 200-hp Continental IO-360 for power.

The SR20 was the end result of the Klapmeiers’ initial effort. As it turned out, certification probably would have cost roughly the same at any horsepower level, but we didn’t end up realizing that until later.” “And that inclined us toward the less expensive, more economical-to-operate 200-hp engine. “We were looking for the largest possible market and the lowest certification cost,” says Dale. The Klapmeiers knew that there were practical considerations of starting off with a relatively low-powered engine. The hope was to attract new pilots as well as existing aviators. Accordingly, the two brothers concentrated on creating an airplane that would incorporate its design innovations in a recognizable package at an entry-level price. Amateurs built the Ark.Īlthough almost all of their homebuilt concepts have been anything else but traditional, the Klapmeiers recognized that a production airplane needed to at least look conventional, with the tail in the back of the plane and the propeller out front. Remember, professionals built the Titanic. Both of these designs were technically homebuilts, but they certainly dispelled any images pilots might have had that homebuilt equated to amateur. The later ST-50 was a corporate single, powered by a turboprop P&W PT6A in the spirit of the TBM-700. The VK-30, co-designed by the Klapmeiers and aerodynamicist Jeff Viken, was an unusual pusher single with the engine mounted at mid-cabin and a long drive-shaft turning a single propeller behind the tail. Technically, both the Klapmeiers were in the homebuilt-design business in the late 1980s and early 1990s, but they had a dream to create a new type of certified, production airplane, a model that would offer superior comfort, performance, simplicity as well as reliability on a modern, 21st-century platform, yet would address the most pressing safety concerns of pilots.īoth Dale and Alan Klapmeier designed homebuilt aircraft for starters, and some of those were indeed sophisticated machines.

The obvious question when any relatively new model of light aircraft becomes such a runaway success is-why? Anyone who has followed the fortunes of brothers Dale and Alan Klapmeier is aware that Cirrus Design was little more than a blip on general aviation’s radar screen as recently as 10 years ago. When I reviewed and evaluated the experimental prototype Cirrus SR20 in the December 1996 issue under the title “Skyhawk For The 21st Century,” I could hardly have imagined that the title would be so prophetic. No other airplane in the history of general aviation has enjoyed so much instant popularity as the Cirrus SR22. That’s all the more amazing when you consider that: a) the SR22 sells for nearly twice the price of a typical Skyhawk b) the Cirrus model has only been on the market for three years and c) no other manufacturer has ever succeeded in humbling Cessna in this way. In fact, the vast majority of Cirrus’ sales came from its showpiece, the new SR22-G2. For the first two quarters of this year, the total number of Cessna Skyhawks and Skylanes was bested by Cirrus Design’s combination of SR20 as well as SR22 sales. For those of you who haven’t heard, Cessna was just recently dethroned as one of the top-selling general-aviation companies in the world.
