Am I interpreting that wrong, but doesn't it say that the 5 knot gust created an unexpected (by the PF) software input pushing the nose down that couldn't be corrected in time by the PF with side stick input resulting in a hard landing causing enough damage that it needed to be ferried back to the UK for repair? If the pilot had full control at the time of a 5 knot wind change, would he have been able to avert the hard landing? Keep thinking of MAX and software causing a pitch down with more dire results.
