Jetranger, there may not be evidence of the Fenestron failure, but here's one to think about - pilot reacts to a PERCEIVED TR malfunction, which may have actually been some strange disruption to TR efficiency (Fenestron Stall?) and carries out TR drive failure drill, secures both engines and makes a very good stab at an EOL, but difficulty in judging height at night causes him to flare early with subsequent long fall raising collective to the stops. Would the Nr decay all the way? Dunno, but this may have happened before.
