Very, very sad and ATSB should investigate this one, despite being reported as RAAus. This is a relatively new type - marketed specifically towards achieving large sales in the (rapidly expanding) GA world training market.
From the (albeit not such good quality) video and the single picture, fairly flat attitude and near vertical impact (no apparent surrounding cane damage along an approach path and engine displaced downwnwards; yaw present on impact with some but not much forward velocity (left wing displaced further forward than right wing). Flaps down but at close to 90* (possibly due to broken linkages from vertical impact force). Difficult to see from the available pictures but from apparent prop damage, engine rotating slowly at impact. Stall / spin?
If a newish GPS / flight system was fitted, the readout would be very informative.
Sincere condolences to families and friends.
