Hi Karsten

my point is that egalitarian CRM proceedures miss the glaring fact that in an incipient major aircraft upset, your most experienced pilot will, on average, give your aircraft berween 25 - and 225 percent increased risk of survival.This is a resource not used by the crew . In this accident the least experienced pilot retained (ineffective)control of the aircraft from autopilot failure zoom climbing to 38000 ft , stalling, then down to 4000 ft .

The Aircraft was hand flown from a stable configuration into a stall situation, albeit unwittingly complicated by the autotrim..... leaving the best aviation experience/resource in the non control role , or absent from the cockpit and not decisively involved throughout.

The problem was being in a thunderstorm at is worst locus of intensity and widest diameter, thence a skill, perceptual (including spatial disorientation) and CRM one on the pilot/company side, worsened by design faults with the aircraft ( pitots, autotrim, stall warning parameters useless in a mjaor attitude upset, no A of A display, digital readouts vs analogue readouts worsening performance in emergency environment, unobserved sidestick)
