I ran the pilots' statements through ChatGPT and asked it to play the role of FAA investigator. It concluded, "Based on the provided statements, it can be concluded that the incident was primarily attributed to the miscommunication regarding flap settings during climb, exacerbated by the challenging weather conditions. "

I'm curious, there wasn't mention in either statement of the F/O reading back the flaps call. Is that SOP or not? If it had been, could it be assumed the Capt would have heard the incorrect readback and corrected it?
