As of April 2017, 350 were in service in 37 countries. The Phenom 100 has an oval fuselage with a 7.985 m³ (282 ft³) passenger cabin, a 1.47 m-high by 0.74 m-wide (4.5'x2.1') door and 1.2'x1' windows. Its unpressurized cargo hold is 1.56 m³ (54.9ft³). Its structural life is 28,000 flight cycles or 35,000 hours, and it is built of 20% composite materials. It has capacity for four passengers in its normal configuration, but it can carry up to seven passengers with a single crew, with an optional side-facing seat and belted toilet. The cabin interior is designed by BMW DesignworksUSA. The aircraft is fitted with two rear-mounted Pratt & Whitney Canada PW617-F turbofan engines rated at a takeoff thrust of 7.2 kN (1,695 lb) to ISA+10 °C. The engines have dual full authority digital engine control (FADEC). An automatic performance reserve (APR) feature boosts engine output to 1,777 lb in the event of engine failure on takeoff. Later model PW 617 F-E models have a ten-minute thrust rating at 1,820 lb. For more information on the development and variants, click here.
