@Tecpilot:
That engine failure didnt occur during a practice autorotation but during a low g pushover! The pilot entered autorotation because of the engine failure and was able to restart during AR.
Well done by the pilot and Ive seen the videos! They replicated it several times over the airfield after having changed parts on the engine. The engine quit everytime they made a low G pushover!
In fact there was another incident with the G2 in Germany. This is first hand, because the instructor is a friend of mine.
They were on a training flight in the same region of the above engine failure a couple of days later, but different machine. During throttle chop to enter a practice autorotation, the engine quit. Just like in the other incident, they were able to restart during autorotation and got home safely.
