Helicopter down outside Leicester City Football Club
STB -Thanks for the link. Looks “Power On” Crab are you able to confirm?
Stagger -
It was a dark, cold evening - you won't find too many insects flying around in these conditions.

No LTE. You can read the report in English towards the rear of the bulletin. There are of course other contributory factors but like is so often the case unless you are internal to the daily ops you only find out how people are living after these kind of accidents. Who knows if this Spanish accident is relevant but it does seem to have quite a few similarities?
Saw this & final report..

Does it mention in the report TR failure?

watch the clip carefully then a repetitive playback of just at what I believe to be TDP at around 53-56 seconds. not this earlier one. watch carefully in the top left corner of the picture. then take a look at the photos in the newspapers of one of the three tail rotor blades which looks ripped off. is that the blade departing?

It's notable that RAF Wessex crews at that time had no simulator training.

except around hot, bright stadium lights......
watch carefully in the top left corner of the picture.
However as has been pointed out, one would have thought that by now, there would have been reports of debris landing in the stadium.

The anticoll on the AW169 sits on a main bus which is shed during double generator failure.

the third blade is likely burnt from the fire, but the wait and see camp wont want to hear that until some form of scientific testing is completed in 2030.
A for what it is worth.....in this video....a Sikorsky S-58T lifting an AirCon from a RoofTop suffers a Tail Rotor Drive failure.....memory serves me the drive shaft couplings stripped causing the loss of drive with no components departing the aircraft.
I talked with the Pilot shortly after the event and he said he jettisoned the load and began to maneuver the aircraft towards a safe landing area and upon getting to a point he thought he could make an autorotation....he cut the engines.
When he lowered the nose to gain some airspeed to be able to flare.....is when it went all wrong.
He was genuinely remorseful when he said he regretted not being able to save the aircraft.

Without any implication with respect to the current accident, the pilot in the Wessex Welsh lake video seems to have done an outstanding job given the circumstances. Looks as though they managed to check some of the yaw and get some directional control before accepting more yaw and a reduced ROD and forward speed.
All the videos all show that once the yaw has accelerated following a serious anti-torque problem, stopping it is going to be extremely difficult, even with a lot of height.

I’m not defending Learmount but as someone who has done his fair share of punditry let me tell you what the media is looking for. They want a very complicated subject explained in two minutes in a way that 99% of the population will understand. This is while, depending on where you are being interviewed, someone is talking in your ear and you’re trying not to think of how many million are listening to you making an ar*e of yourself. Not as easy as you think.

The fast moving spec seen at 46 sec is, Imo, not a part of the aircraft. However the falling object appearing on the left at 54 sec's and disappearing into the floodlight glare at 58 is of more interest.
Hi Jeep’s
An autopilot with only 10% authority wouldn’t be much use as an autopilot. Individual series actuators typically have 10-15% authority with two actuators in series giving 30% (ish), this is then usually extended to 100% authority by use of parallel actuators. I totally agree an actuator runaway will be limited by its authority.
I‘m not suggesting any of this is relevant in this case.

Just worth noting that I know someone who was still at the game and has been to several and seen the helicopter take off.
apparently, it was all normal (including that first initial yaw input when it first looks controlled). You cannot make it out too well in the video, but the gear retracts and it begins a rotation - apparently as it always did.. At that point it never seems to recover.
im no expert and could be coincidence - but could that suggest a peddle / input problem. He stated that it actually didn’t sound too out of the ordinary. The strange noise people seem to be referring to from what he saw was the pitch of the blades against the air as it began to rotate seemingly uncontrollably.
just thought I’d share to maybe shed some insight from someone who has some basic understanding of aircraft / rotors rather than just a regular member of the public.
it maybe a result of the cause rather than the cause itself, but thought I’d share it with people much more knowledgeable than myself.
