The Aviation Herald reports that in an incident that took place on 26th July but that has only come to light in the last few days, an Airbus A340 doing a FRA-MAD route performed an emergency landing in Valencia after it could not land in Madrid due to thunderstorms.
3 Ryanair 738s also performed mayday landings, though
only one of them actually landed below the 30 min reserves, but only
marginally. These have been discussed elsewhere, and have been widely reported, whereas the LAN
340 had been kept quiet despite what appears to be a more critical situation.
According to the report, the A340 lost an engine during the approach to VLC, where it landed substancially below the minimum reserves.
Although the report does not state that the engine loss was the result of low fuel, it would seem too much of a coincidence if these were not related.
It would be useful to hear the views of professionals, as to what could have happened here. Is 800 kg in one wing tank low enough to cause starvation in one engine? Might this have been a deliberate shut down to save fuel?
Are engines fed from different tanks, and so engine loss can be staggered in a low fuel situation?
