OK folks, here's how it looks, the latest EH101 dunking was caused by a rotorbrake fire of such intensity that it required ditching.
The rotorbrake came on in flight hydraulically and was uncommanded despite being hydraulically disabled after an Italian disaster to a pre-production model.
Interlocks with the Sonar winch system which uses the same hydraulic system failed and the R/B came on in flight.
A hideous amount of burning in a very short time, which torched the gearbox casings(what are the front gearbox casings made of?) made the pilot ditch[and so say all of us].
Guess what. The a/c was trialling Sonar at the time.........
