A very simplistic question from someone who has many pax hours in helicopters. Is it fair to say that mechanical failures are happening more on helicopters? If so, is this because of modern design - i.e. Lighter components to save weight/increase payload, etc, etc.
All my hours in Sea Kings, Pumas, I never remember a Main gearbox, bearing, or tail issues, ever - certainly not 'accident' or grounding issues.
