MTU plans to build 10 engines a month in 2015. Initially MTU took 50 days to build an engine, but MTU engineers have now got this below their 36-day target with one engine taking around 35 days to produce. The company has built all the engines for aircraft to be delivered this year and has also completed testing on two spare engines destined for the main A400M base in France at Orleans.
According to Europrop, the engines are providing better-than-expected specific fuel consumption performance of around 1%. Production aircraft will also be fitted with a propeller brake produced by Italian company Umbra, eliminating the need to tie the propellers down when the aircraft is parked on the ground as seen on the development aircraft. This option has been selected by most of the A400M customers.
