Although it gained EASA certification in May, the Europrop International (EPI) TP400-D6 engine that powers the Airbus Military A400M airlifter subsequently encountered two problems. But according to EPI’s president, Simon Henley, they have both now been resolved.

The first problem concerned a fatigue crack in the idler gear that occurred at cruise propeller speed. This led to an in-flight shutdown and also caused the cancellation of the A400M’s appearance in the flying display at Paris as a precautionary measure. With the fault located, EPI instigated a redesign to shift the resonance point out of the running range.
