I think some of the contributors here will be interested in the SI into the Tucano engine failure / gear-up landing in Jan 13 (see
separate thread). Firstly, a familiar tale of airworthiness failings at the EA. Secondly, it appears that the MilAAIB's human factors specialists (who I believe are civvies at RAFCAM) were looking for failings that were not there, came up with some hare-brained stuff about cockpit gradient, and had their theory politely dismissed by the panel. Good too see some forthright comment from the Convening Authority, too.
