Hi ROAN,
Tecnam have published a mandatory service bulletin to disable the Rotax soft start feature on the 912 whilst an investigation is completed into false activation of the soft start (retard ignition timing) during flight here:

without knowing the specific details of the issue (e.g. does it only impact Tecnam due to a potential unique way they connect the ignition systems) or is it likely to be applicable to all Rotax engines fitted with soft start feature no matter who the airframe manufacturer is?
Keen to hear if anyone has more experience with this issue please.
Regards,
Byron.
