In post #8 it says that -
The investigation found that moisture had contaminated the transmission oil causing corrosion of the internal components of the transmission-oil cooler and the clutch. Corrosion products from the oil cooler caused a blockage resulting in reduced oil flow to the clutch. The subsequent damage and overheating prevented the clutch from functioning properly.
I have three questions please -
1. Can someone describe in simple terms what type of clutch is fitted to the Bell 206.
2. How can corrosion in the transmission oil result in the helicopter's main rotor mast being severed just under the rotorhead?
3. Would this severing of the main rotor mast have occurred in-flight had the clutch re-engaged before they landed?
