That is a reasonable choice. The images appear to show a very high pitch on the port prop-rotor coincident with it starting to depart to port. The report and data on this accident would be interesting to evaluate, as it may be that the rotor needs some help within the operational envelope.
General question: is there any data on this V-22 loss?
Data? No. Reporting? Yes.
IIRC, the pilot identified a sink rate but was unable to arrest it with the power available. He was #3 in a three-ship and was apparently caught in a strong downdraught.
