What's the role of de-oil solenoid? (scavenge the oil from bearings or gearbox and heat up this oil...?) may be it's needed for ETOPS aircraft?
Any comment regarding the failure of the drive shaft, splined drive (if it is little bit common, but it seems that the failure of the gearbox or the tower shaft is very rare?)
Feedback appreciated. Thank you
Best regards.
