Yer bits dropping off?
Shawn,
Just a consideration.
Some years back many (ex-212) 412 operators were beeping down to 97% NR for cruise flight (which really does nothing for you with 4 blades except get very exciting trim actuator-induced TQ spikes in the >105KIAS mast torque limitation range!). When the EP came along, the same cruise reduction started causing noticeably increased wear on the rotating components of the head, some of which were being damaged quite markedly within very low flight times.
Bell then advised that the probable cause was pilots climbing the aircraft regularly (and at varying ROC!) at less than 100%NR, which was damaging said components in very short order. Subsequently, Bell advised 412 operators not to beep down at all for cruise flight in any 412 variant and to maintain 100% throughout the normal twin-engine flight envelope. My own company and many others subsequently withdrew any reduced-NR cruise operations. No further occurrences of such increased wear in rotating components were subsequently encountered. The climb at 97%NR in the EP model was the particular hard-wearing activity. (Of course, any prolongued operation of a 412 with poor tracking/rotor balance will also speed such wear.)
FYI
