Comparisons of the various types of helicopter, while interesting, aren't really helpful...
The problem is that MRG has failed causing two hull losses and the loss of the lives of all on board. After two incidents and major technical investigations we do not yet have a fully developed understanding of the failure mode, a package of modifications to prevent its recurrence, or a workable system to detect the failure once initiated.
After the second incident the manufacturer initially and publically concluded that MRG failure was not likely and suggested the investigation of the suspension bar assembly and a thorough review of maintenance records. Then debris was recovered which enabled the AIBN to conclude that the two incidents did indeed result from similar events in the epicyclic of the MRG. The investigators publically disagreed with the manufacturer and some of the regulators over allowing the type to return to service with increased inspections.
Many passengers lost confidence taking the view that there is a serious unresolved issue which as things stand might result in a third incident.
Some here have labelled them ill informed, hysterical even stupid; led on by a sensationalist press.
The customer may not be an expert, sometimes the packaging may sound sensational even hysterical - however he may also have a valid point!
