Unlike the alloy props of old D8s the carbon fibre prop disintegrates causing lots of damage
Perhaps I'm missing something here. Jet engines have to undergo tests to ensure a blade failure is contained within the engine. There are instances of parts being thrown through cowlings at the fusilage, but they are few and far between.
Landing gear failure does happen - be it failure to extend or collapse on landing - and for the Q400 disintegration of the carbon fibre prop will happen and the resultant injuries may be fatal. (Well done SAS crews for moving pax/shutting down the engine).
One wonders on what basis certification was given for the use of these props. Perhaps in the light of recent events the seating of pax in the propeller affected area should be banned.....
