Last year at EAA AirVenture Embraer announced the first flight of its Phenom 100 very light jet. While it wasn’t able to announce type certification at this year’s show in Oshkosh, Wis., the Brazilian aircraft manufacturer did say yesterday that the twinjet is nearing the finish line. So far, four flight-test Phenom 100s have logged more than 1,000 flight hours in the certification and maturity campaigns. Meanwhile, the first Phenom 100s to be delivered to customers this year are already in the sub-assembly production phase, according to Embraer. The company reports that several development and certification flight tests have been performed to date, including low- and high-speed characteristics, stalls and flutter. Additionally, the test aircraft have flown in natural ice conditions, which will allow the aircraft to be certified for flight into known icing conditions upon delivery. Crosswind tests were also performed in Punta Arenas, Chile, earlier this year, and operational tests in high-altitude airports were recently concluded in Cochabamba, Bolivia. Systems and performance tests are ongoing, and one test aircraft is currently in the south of Argentina undergoing cold-weather tests. All structural static tests have been completed.
