It’s all in Record Only investigations (published in December) so just the one link:
Record-Only Investigations Sept-Oct 2024
R22 Instructor and student practising engine failure in the hover, touch down with left drift and rollover.
R44 on first lift on first solo, student surprised by yaw, ends up on right side.
R44 on first lift on first solo, nose rises more than expected, ends up on right side.
OK Robinson-bashers: there are just lots of 22s and 44s out there in the hands of very low-timers. In comparison, if you want to be safe on the road, buy an Aston Martin. After all, very few of them crash - mainly because there aren’t many to begin with, not because 500hp and two tons is intrinsically safe!
