The turboprop engine powering the Airbus A400M airlifter has been certified by the European Aviation Safety Agency (EASA).
Europrop International (EPI), the four-company consortium responsible for developing and building the TP400-D6 engine, said the milestone came after a test campaign that included more than 8,000 flight hours and more than 4,000 hours of ground testing.
The May 6 announcement came just days after EPI said it had signed an amended contract with Airbus Military settling outstanding issues related to the much-delayed and over-budget transport plane.
EPI involves partner companies Rolls-Royce, Snecma, MTU Aero Engines and Industria de Turbo Propulsores.
In a statement, EPI said the TP400 is the first large turboprop certified by EASA and the first military engine to be cleared by the agency to civil standards from the outset. At 11,000 shaft horsepower in a three-shaft configuration, the TP400 will be the most powerful turboshaft engine to enter service in the West.
Military certification is expected next year ahead of A400M deliveries getting underway to lead customer France around the turn of the year.
Airbus Military has orders from seven European countries for 170 aircraft, with an additional four being destined for export customer Malaysia.
The seven partner nations in the program are Belgium, Britain, France, Germany, Luxembourg, Spain and Turkey.
