Stick skills v airmanship
Example: EC 130 down at the Grand Canyon
Under pressure
“We don't rise to the level of our expectations, we fall to the level of our training.”
I do believe that all comes down to training.
Few have probably ever used a full pedal and muscle memory means they either don't put the boot in or end up with the one foot pushing against the other.
I really don't think that shearing a pitch link, or it never reaching its hours features in the thought process.
Most of us would rather not think about what is going on in the mechanical bits. If we did, we wouldn't get into the damn thing to start

The helicopter has so many single point failure modes, why would you ever entrust your life onto an 8mm cyclic pitch rod (when we give elevators 6 parallel cables)
At the same time, I always like to proactively think about the specific system or component that get stressed at that particular moment in the course of that specific maneuver while you execute it.
it can destress or possibly let you react faster to an emergency that you had already linked in your brain. (jack stall, MTB overheat, loss of tail thrust,... or simply lack of power --> go around)
Because the "Full Boot" is a relatively exceptional event, it is hard to build a motor control mechanism around it, the brain of the pilot has to come into play.
Try now.
looked at a report that was done at the same time, for AATD, and modified was "~58", full left pedal, normal was "~38" according to the same notes. That had a mod on the MRB which was STC'd by me, and the same on the TRB which we did not STC.
Robbies are like a swiss watch, like a Piguet, neatly built but best not to use as a hammer. They do what they are designed to do really efficiently, every washer and locknut earned its way on board. They are responsive... assuming risks to the pilot only is between him and his/her god. if the flying stresses the machine, then that gives a risk to someone else. If hot dogging over people is done, then the 3rd parties are at risk of anything going wrong. Can't say what the probability of that is, nor can the pilot.

212man - seems like he should have made sure his 'mates' kept the video off social media - there is always someone with a camera/phone there when you decide to do something stupid - doh!

flounce
verb [ I usually + adv/prep ]
UK /flaʊns/ US /flaʊns/
to walk with large, noticeable movements, especially to attract attention or show that you are angry:
"Don't expect any help from me in future!" he said and flounced out of the room.

Some of Frank's decisions on weight savings drive me batty! You can get a machine with air conditioning but not a proper oil filler tube.
Final comment, note when you come out of the right-hand high-speed flight, that suddenly unloading the TR which swings the nose into the direction of flight will most times give a prompt overspeed of the engine (and MR) the governor is good, but not that good. Then have a look at the MM on overspeeds.... and then go check your bank account.
The real problem is that at least in my experience this is not taught during any flight training for PPL or leading up to commercial, as all flight training focuses on flying safe and conservative, staying away from the limits of the aircraft as far as possible. Many a R44 pilot would have been caught out unprepared the first time they experience it.
In my view that is wrong and dangerous. You need to know how the handle the a/c at the limit so that you are trained, and current, on what to do if the unexpected happens (e.g., windshear on landing, turbulence, etc.).
Every pilot who does aggressive manoeuvres or quick power changes (e.g., as part of game management work) knows this and readily and easily overrides the governor as required. Again, it's a non-event. It is covered in the POM too and really easy to handle once you have experienced it.
If the game/mustering is routinely resulting in winding up the rpm over the limits then it might be time to put a recorder on the machines that are doing that, I used a South African designed and built system 12 years ago, a simple addition.

But,
being "TIA",
maybe.....
The CP or owner's comments on the video would be interesting. If the pilot was the CP or owner, that also would be interesting.
The link to the local news headline has some other articles of interest about local aviation.
1. What happened at George in January? The 3 fatalities there, were they insursty or regulatory, curious on the experience levels quoted.
2. What was the 20 Y/O accident event with the C185 triple fatality, and what was the helicopter involvement in that case? That sounds odd.
The first flopping about that happens here on the far side of the pond is about 125' from the camera. Sound takes 0.11sec roughly to go across the area in between, roughly, its not standard atmosphere... its the bush at some altitude.
In the first of the turns, the RPM drops from almost exactly 102% to a shade under 99% (98.3%) and then a few seconds later get recovered to about 102%, still in the left turn. At that time there is not much doppler shift going on for the MR, in 6 seconds it shifts 9' closer to the camera. that's a +0.9% doppler shift from translation to the observer. The main frequency line is the exhaust harmonic to the main rotor blade rate (expected the TR line, but that comes later and is not the highest signal, and being a higher freq tends to fade quickly), and during that time the chopper is rotating relative to the observer and the exhaust signature shows that rotation. at the lowest and the highest RPM point, the exhaust is doppler high to the source, the rotor RPM is 98.3%, so the guvn'r is being defeated by the boot. using the same corrections the peak RPM reached is 104.9%..
So, in this case, it's the under-speed that was out of sorts, and the engine didn't quite beat the limit for the POH of 105%, except for the *** note on the engine, that intentional operation above max continuous is prohibited. (102%) So, the power on rotor limit is either 101 to 102^ but is almost certainly using the 99-102% normal range. Both the modest under and over-speed were either intentional, and breached the limitations, or were unintentional, and arguably didn't breach the limitations, just incompetence instead. Either way, it's not impressive.
Being kind, that is a modest excess twist of the throttle, it's not the governor's response... its doing a great job in spite of the klutz at the wheel (there was an excellent article on the governor response done some years ago, and the response is really neat. Was related to taking the RHC gov and putting it on an experimental helicopter, it's darn near dead beat in response to an error signal. The circuitry acts like a PID controller but does it in a curious way, 10 years since I read it last, so... anyway)
'IMHO"

fdr - I hadn't taken into account your experience as an air safety investigator - great audio analysis
