Looks like there is some considerable wind blowing as well -
I can only imagine the paperwork that this incident will create.

Quoting KPDX (Thread starter): Wow this has gotta suck! And also note the guy how he pushes the Blackhawk back over, are they really that lite?
I gues the blackhawk was standing on just one wheel, he was just fightin the wind to move the CG back to a place were it would rest on 2 wings, not carriying the entire blackhawk's weight on his arms. Anyway, what he did was stupid, he could have been killed, and maybe it wouldnt have tipped over if he hadn't tried to move it back into place, notice how it had more momentum after it was pushed.

A few points of note...
1.. It is NOT a Blackhawk.., but the Navy version called the Seahawk.
2.. It is NOT on a Carrier, but looks like an Arlegh Burke Class DDG Destroyer.
If you noticed the engine plug streams blowing in the wind, they were in pretty heavy winds - seas. I was shocked they were even getting ready to launch. Another point to note... they were not using the arresting system. This is a cable system that allows the helicopter to land on teh deck in rolling seas. The helicopter drops a hooh that locks into the track on the deck and pulls the helicopter down, locking it to the deck.

Are you guys seriously suggesting that the chap managed to make any impact on the motion of the 7 tonne Blackhawk as it rolled on the deck, due to the (obvious) gale force winds that were causing it to roll...
If you are Luisca, you're deluding yourself...
The helicopter rocks back because the wind drops, not because the guy makes a feeble attempt to push it over.

The ground crew had nothing to do with returning the helicopter to its level stance. The wind subsided and the copter fell back on its own weight. Can't imagine the hell that crew went through when they had to report to thier superiors!

Quoting TIMC (Reply 2): I think that video must be faked somehow.
If that was really filmed on an aircraft carrier, how did the cameraman keep his hand so steady with all the swell?
I feel the same way. In addition how could a helicopter weighing in at a couple of tons tip over while there are several crew members who do not appear at all to be affected by the ships movement. Could the heli be some kind of mockup for possibly training the ship's personnel in helicopter operations.

Doubt very highly it is a 'mockup'.
Couple of observations:
The wind is very definitely blowing the clothing of the crew as well as the 'remove before flight' pins on the Hawk. The crew provide a significantly less profile to the wind so they didn't get blown overboard.
After it tips over the wind still pushes it, ever so slightly, toward the railing.
A second crewman, apparently aware of the foolishness, urges/pulls/convinces the first crewman back after he tried to right the Hawk
At one point lights start flashing on and off on the tailplane. No, it's not a mockup.

I talked with a fellow co-worker today who is also a UH-60 Crew Chief in the Guard. I was told that gusts at 15kts require the blades be secured... gusts at 30kts require the helicopter to be chained down.... and if it's light on fuel.. look out.

No such wind restrictions apply to a plan vanilla UH-60. The rotor system may start and/or stop at wind speed up to 45 knots. So if the wind is 40 kts, go ahead and start your Hawk. The aircraft is a stable machine on the ground in windy conditions, as long as the tail wheel is locked and brakes set. I can't comment about shipboard conditions however. I've seen anti flap assemblies (on the main rotor head) broken from high winds, and the only other isssue was a broken tail lock pin from winds. The aircraft stayed on it's wheels just fine.
1.. It is NOT a Blackhawk.., but the Navy version called the Seahawk.
2.. It is NOT on a Carrier, but looks like an Arlegh Burke Class DDG Destroyer
Both correct.
Major difference is the Seahawk has the tailwheel near the back of the cabin vs. at the end of the tail. I'm not sure, but this may slightly raise the CofG while the helo is on it's wheels compared to the Blackhawk.
Also, carriers have a clear deck & sail directly into the wind during launch & recovery. Destroyers sail with the wind about 30 degrees to either side, since the superstructure would create unsafe & unpredictable turbulence if they had the wind directly on the bow.
If you look at the video, you can see two tracks on the deck where the hauldown system that EMBQA mentioned would travel while the helo was moved onto the deck from the hangar. I have no idea why it wasn't used, unless it was broken.
Could they have been doing some sort of maintenance checks that required an engine start?

They are carrying out a 'Straightening' which entails the moving of the helo with the Beartrap (RAST) system and the Tail Guide Winches (TGW). it could be an OHP class frigate (FFH7) or an Arliegh Burke [Flt 2](DDG51)
Look at the Video at 200% and you can see the TGWs on either side of the helo (from the deck edge hooked on to the tail) and the fact the helo is traversing aft leads me to believe they were straightening the helo outside the deck motion limits (3 deg pitch and 10 deg roll). The winds may have had some impact but deck motion is more likely without seeing the horizon it is hard to tell.

It's not an FFG-7 Perry Class Frigate as it has two arresting tracks. Perry Class Frigates only have one. My money is on a (Flight II) Arliegh Burke Class Destroyer. 'Flight II' is just the second generation class of the Destroyer were they added the Helo hangar.
My first 'real job' out of high school was working for the Maritime Engineering and Design company that designed the DDG-51 class.

Quoting Visityyj (Reply 5): There is no camerman, it's a CCTV camera fixed to the ship so it rolls with the ship giving a 'steady' image.
I'll look for it but last year I put up a video taken from the hoist winch of a USCG Jayhawk looking straight down at a hoist in the basket. It looks like the helicopter is rising up and down dramaticly, but in fact the helicopter is hovering at a constant height, and what you are seeing is the tops and troughs of the waves. Same thing is happening here.

Wasn't the wind, it was the rolling of the ship in the sea.

Just another day on the sea, the more time you spend out there the less it affects you.

I would say yes, I was in a Blackhawk unit in the Army, and seen a lot of USCG Jayhawks up close (Same tailwheel) and the naval versions definately sit with their arse up in the air.

Looks like the video came off the HOSS flight deck camera, it's mounted to the superstructure, not a handheld cam corder.
The flight deck is a FFG-7 frigate flight deck.
There are supposed to be pitch and roll limitations of what can be done at certain sea states. At certain trip points, the aircraft should have been secured for "heavy weather."
It looks like it was only held in place by the beartrap and it wasn't griped down properly. To me, it looks like the maintenance night crew got complacent, and just thought it was another night for maintenance, pushed the helicopter out the back for maintenance.
The ship driver will probably get some blame in all this as well even though he has no control over sea state, he'll get the blame for allowing the aircraft to go unsecured on deck.
Good judgement comes from experience. Experience comes from surviving bad judgement.

I stand corrected. After a second, better look it is indeed a Perry Class Frigate flight deck. I forgot they had two separate arresting tracks. It would be interesting to find out what really happened though....

Along with the LSO and the Deck Director. Someone on the bridge or in the Ops room knew what was happening because thats were the CCTV is controlled from and the camera followed the A/C as it rolled over.
