The Lancair ES-P is a specialized, pressurized four-seat aircraft developed by Lancair International, based in Redmond, Oregon. The aircraft is a hybrid design, integrating the pressurized cabin structure and design of the Lancair IV-P with the larger wing and fixed-gear layout of the ES model. This configuration was intended to provide pilots with the ability to cruise in the flight levels while maintaining better runway performance and handling characteristics than the IV-P, all while reducing the weight, cost, and build time associated with retractable landing gear.
Power for the ES-P is provided by a Continental TSIO-550C piston engine. According to KITPLANES, this powerplant produces 350 horsepower at 2,600 rpm. While the standard installation utilized the Continental engine, Lancair noted that at least two aircraft were equipped with Lycoming IO-540 engines via custom mounts. The aircraft's performance is notable for its speed and range; while Lancair lists a cruise speed of 215 mph for the ES family, KITPLANES reported a true airspeed of up to 293 mph when operating at FL240. The aircraft features a gross weight of 3,550 lb and a rate of climb of 2,000 ft/min.
Designed for the civil general aviation market, the ES-P offers four seats plus luggage space. Fuel capacity varies by configuration, with Lancair listing 105 U.S. gallons and other sources citing 121 gallons, which extends the aircraft's range to over 1,300 nautical miles. The airframe measures 25 feet in length, with a wingspan listed between 35 feet 6 inches and 36 feet 6 inches depending on the specific model variant.
Production of the ES and ES-P kits ended in 2012. By December 2011, Lancair reported that 90 aircraft from the combined ES/ES-P series had been completed and flown, though a specific total for the ES-P variant alone was not provided. Despite the end of kit production, Lancair continues to support these aircraft through the provision of technical assistance and replacement parts.
