1. Loss of control on penetrating an active mesoscale event.
2. Pitot icing was rapid rather than gradual on account latent heat in updraughts.
3. Overspeed occured.
4. Recovery failed when penetration of a second mesoscale event took place NNW of ORARO.
5. Cabin Vertical Speed was following flameout and stall.
@mm43:

Sounds reasonable. Would you assume the a/c to have been at FL350 still at time of LKP?

Even if the generally estimated 4 minutes from LKP to impact might be inaccurate, at 7 minutes that would still be a decline rate of 5,000 feet per minute. While making a left bank between 35° and 50° at >607knots (!) (based on 75km from LKP to search area in 4minutes). And then impacting pitch-up, slight bank? - without maydays? Wouldn't there be specific injuries detectable on the bodies at a decline rate like that? Would the crew not have been ordered to caution position before entering MCS at ORARO, as they already passed a little one at SALCU?
