Very sad to hear of another "bladder tanks could have made difference" mishap.
Regardless of some gust, not the best choice of approach/direction, wrong wind assessment/LTE, pilot's experience or whatever combination led to this.
It's easy to make mistakes flying helicopters and most likely low time pilot getting some hours towards commercial or enough R44 PIC time for jobs later on.
How many more crashes like these, to have bladder tanks compulsory on all R44s worldwide, no exceptions, soon as? The rotor brake switch probably saved some lives, but... I thought ATSB, NTSB, AAIB etc are there to ensure improved safety based on accident investigations, yet we don't see much happening. Is it RHC's lobbying in place again?
Food for thought:
