Low Hanging Fruit
One of the major oil companies has gone on record asking a major US manufacturer (and the message was, I believe, passed to their French, German and Italian brethren) ......"Here is a flight bag with 10 kgs of metal - please put that back in your helicopter where it will do the most good, we will gladly accept 10kgs less payload as a price worth paying".
That after having to live with fragile tail-rotor systems and components that are scrapped if they are even scratched.
