Straight and level at 1700' and 110 kts.

More VHA blade issues? 3 pax isn't exactly lightly loaded, so the infamous nodal beam interaction vertical hop probably wasn't at play. Personally I am still immensely uneasy at their certification without a dynamic load fatigue assessment. It doesn't appear that VHA does flawed specimens for fatigue testing either, which is more than head scratching. According to the TSB, C-GEBY blade failure was precipitated by aggressive loading conditions after engine failure on a fatigue damaged blade set (thought VHA vehemently disagrees).
