Please clarify the Ch-148's availabilty % ? It is not actually meant to be flying so how can you calculate an availabilty rate?
Regarding wider S-92 availability, it is really dependend on how you count it. My company counts all unscheduled events in availability figures, so, an unscheduled MGB change for whatever reason would be counted in the availability statistics which in turn are reported to Sikorsky. Scheduled (1500 hour) inspections are not counted as they are predictable events.
