today.... :(

one of the pilots, RIP.

Flipn hekkk, when did that happen??:eek:

That made the hairs on the back of my neck stand..

RIP:sad:

NH-90 accident occurred today, June 1, during an air display at Vigna di Valle, the Italian Air Force Museum on Lake Bracciano, north of Roma.
:(

Also today, an Eriksson S.64 crashed while picking up water from a lake in Northern Italy, but on this occasion the two crew got out.

Oh! ***** :eek:

:sad:

R.I.P.

NH90 down in italy

Just got news today of one of the NH90 helicopters had a crash in Italy while showing off a rolling turn. It all went pear shape when the helicopter failed in the turn at low altitude and crashed into a lake, the pilot was killed.

These helicopters are built to withstand heavy crashes and it was lucky not all on board were killed.

The Video on u-tube has now been withdrawn (Thankfully)

RIP

Other video link to the accident.

A couple of weeks ago another crew landed briefly with the gear up and a multistar general rank officer onboard.:eek:

Condolences to the family members of the deceased crewmember.

An NH90 helicopter, serialled MM81519 EI-202 of the 1 Gr Sq of the Italian Army based in Viterbo crashed on June 1, in the Bracciano Lake at 15.15L causing the death of Cap. Filippo Fornassi. The other 2 POB (People On Board) were rescued and survived the injuries. The aircraft was at the end of its display in the Ali sul Lago airshow in front of the Italian Air Force Museum, at Vigna di Valle airport. I was attending the show when I saw the helicopter performing a fiesler with an apex at low altitude: as soon as the aircraft’s nose was diving towards the lake, I understood that the pilot could not recover the chopper before touching the water. The aircraft touched the surface of water and broke up in many pieces before ditching.

That's some photo.

Can anyone here familiar with the NH 90 comment on the maneuver?

With the limited set of facts available, is it possible to comment if this was done at too low an altitude, or if it may have been mechanical related?

"A Fieseler is an aerobatic maneuver named after Gerhard Fieseler. The pilot puts the aircraft into a vertical climb, then quickly points the nose straight down into a dive (by using yaw from a rudder or tail-rotor), pulling out at the same altitude as the maneuver started, but with the nose of the aircraft pointed in the opposite direction."

Also known as a "hammerhead" turn. I think the Cobra guys used the manouver to deliver ordinance straight down on otherwise defended positions.

Clockwise propellers go better to the left and counterclockwise main rotors (like on a Bell) go better to the right if I remember my hot dog days. Anybody current on this is welcome to correct.

Just looked at the video and it looked to me like more of a wing-over than a hammerhead. There was a pull-up, then a sloppy looking left roll to vertical with almost a bit of tuck. If it hadn't over-banked to vertical it probably would have worked out. As it was, not enough altitude to recover. It hit the water flat, and you can see the nose jerk up slightly just before it hit the water - that would be aft cyclic control input. I looked at the still picture of it hitting the water and again it looks like the pilot was doing what he could putting pitch on the blades. Another 50 ft and he would have made it.

Bad news! :(:(

On the footage, I can see during the descent, 2 lightnings located close the air intake. Any idea? the weather is grey, no sun....

I think, those lightnings are reflections on the windscreens...the airintakes are almost behind the main rotormast.
Another part is, the NH90 is completely Fly by wire, may be these computers limited the intended pull up???

Sad Accident

skadi

I normally don't comment on 'what happened here' videos, but all these fancy names for the turn don't appear to matter. It looks like a simple wingover carried out at very low level. What would help would be the video showing the entry height as it does not appear to descend that much after the turn. If you enter at very low level you give yourself NO margin for error. For everyone involved's reputation, I hope my simple view is wrong :(

I wonder if there is a particular difficulty in judging (or misjudging) height over water when carrying out a display, as I can think of several other similar accidents involving Fixed Wing aircraft - RN Jetstream at Weymouth and RAF Nimrod in Canada.

Anyone know the elevation of the lake in question?
