Great pilot job with recovery...but what is wrong with Holly fenestron and Airbus H135?
Nothing wrong with the helicopter
looks like a downwind approach and turning into wind in the high hover.
Fenestron dont like wind from some angles - lots of pedal movement necessary to do it smoothly.
would better have flown a turn with speed, still, he got away with it and has a story to tell and others can learn

If that was yesterday or today and the windspeeds in Poland were anywere near what we had in Germany, no wonder he nearly lost it. That fenestron and fin offers a huge surface for crosswinds. If he was even downwind in these winds, he's lucky he didn't crash it.
In the beginning somebody taught me to approach into the wind. I suppose that even holds true if the wind is very strong?
I would consider this straight into the wind. So what is wrong with the anti torque device (did somebody ask this question already?)

Not sure which way the wind was blowing, but it sure looks like a classic case of http://www.faa.gov/documentLibrary/m...ar/ac90-95.pdf, albeit with things spinning in the EU direction instead of the US direction.
Great recovery.

Someone with a video camera on every flight
Interesting footage and no assumptions made here as I have no idea of the circumstances. An ops director once told me "Assume that the authorities, Chief Pilot, Director of Ops and Safety Director are watching every take off and every landing". With social media it is so very true. Every 'boring' or 'routine' flight, is a good flight.

Well that's damn interesting. How do we account for the left yaw, then?
with 15 knots of wind?
Manageable - but you have to anticipate that wind from about 30-45 degree out of centerline, regardless if it is from the front or back, might give some wobble due to disturbed airflow around the fenestron.
No way to hurry through an outside landing-
Proper assessment of the landing site, how to approach and how to depart later shouldn’t be rushed. As you can see here, instead of landing and helping time will be wasted for paperwork (luckily only)

Big DC windbreak
That mahoosive distribution centre opposite would I suspect create some interesting dynamics and that coupled with little bit of fenestron stall - looks like it induced a little sphincter twitch..... still good recovery and fly away to calm the nerves.... remember this happening in a gazelle in Germany many moons ago - never seen an airtrooper run so fast 🤣🤣
Fenestron stall doesn't exist.

Glad that you seem to have better knowledge than the AAIB - they seem to think it existed and so did we 89-95 - BAOR / NI / Op Granby

just inappropriate Pedal movement
with Fenestron you have - non linear - longer travel

The whole construct of Fenestron Stall was demolished when Aerospatiale demonstrated recovery from in excess of 120 deg/sec left yaw with full right pedal and it stopped perfectly (albeit with the little red Tq light flashing).
It was later understood that Fenestrons have different handling characteristics to conventional TRs and need prompt and sometimes large pedal movements to control undemanded yaw where the pilot has got behind the curve regarding actual pedal position compared with required pedal position,
