More information from `Liberation', Fri 26 Aug, p19, concerning the crash of the ATR42. Apparently there's a mechanical fuse between the pilot and copilot, in case of blocked controls. It's sufficient to force the controls to break the fuse, possibly accounting for why the copilot wasn't able to do much. But apparently she still retained the means to `control the descent' [`la moitie des gouvernes de profondeur' - my colleagues, who are not pilots, have difficulty with this phrase also]. The inquiry will say if the copilot attempted this manoeuver. `The recordings of conversation inside the cockpit revealed an amazing exchange between the pilot [...] and the co-pilot [..]' The copilot, very surprised, asked the captain what he was doing. She understood the response `To die, to die', and made an emergency transmission `Help, help, the captain is .....' and that was the end of the CVR. Horrifying. The report suggests there was only ten seconds between the pilot putting the airplane into a dive, and the `crash'. But they also say that the aircraft was at 3500m altitude, rather more than 11,000ft. I think they mean that there was only ten seconds between the beginning of the manoeuver and the end of the CVR or FDR recording, corresponding to the in-flight break-up of the airplane. Apparently this is all quite inexplicable. There were no obvious indications of disturbance, he'd passed the medical on 7 July and a check ride on 20 July, all routinely. Apparently, he'd also arranged to meet a friend in Casablanca after the flight. An alternative hypothesis was an attack, but this were completely ruled out by the Enquiry Commission's president. It also turns out, contrary to what Learmount supposed in the IHT report, that there was another suicide, 9 Feb 1982, a DC-8 of Japan Airlines in the bay of Tokyo, a few hundred meters from Haneda airport, after an aberrant manoeuver made by the pilot. `The inquiry revealed that shortly before the landing, the pilot suffered a severe "psychic disorder" similar to a schizophrenic crisis. The pilot had been hospitalised before for more than a year for mental troubles. The japanese jucidiary decided not to indict the responsable managers or the doctors of Japan Airlines who knew about the medical situation of the pilot.[...]' Peter.
