Yesterday I send an incident report to technify , they asked me for the data file of the engine , we will ask to our mechanic , but last data loaded show nothing , so we will see with this new one . As I heard there is several pilot who got this problem on CD 155.

Dear Pierre,
Has your FADEC been updated with the D4-v1.70 software (only applicable for TAE 125-02-114 engines)? Mine was, in February, but I haven't experienced this alarming issue at all, thankfully!

Pierre,
Temporary power loss with vibration is often related to injector leads chaffing. Inspect the harness as far as possible for any damage.
Another possibility is a bad connection at the injector plug. Check the plugs to ensure the connection is not splayed open and ensure plugs are securely fitted.
