Released the nose wheel lock with plenty of pedal applied?

The AAIU has already determined it was not the crewís fault. The pilot was licensed and qualified by the authority and followed the published SOP to the letter, nobody to blame.

But even less seriously...looks like he wanted to taxi to the left, aircraft resisted so he tried a little harder, then remembered the nosewheel lock and when it released the aircraft spun left with full left pedal applied. This threw the pilot to the right still hanging on to the cyclic and collective. So on top of the yaw the pilot has now got the collective coming up and full right cyclic. The aircraft is truly embarrassed at the overreaction by the pilot to the initial slow left turn and rolls over in shame.

fodder for weeks to come on pprune

What surprises me is pilots are still finding new ways to needlessly prang helicopters.

The guy legging it towards the corner of the hangar caught on pretty quick. Best decision-maker portrayed here!

Yep, watch his body language as the 169 inches forward - he knows bad things gonna happen.
Puma guys can sympathize.

But this looks like an old way!

However, I do wonder if this has any similarity to the tragic accident at Leicester football ground....it looked like yaw control was completely lost.

Looks more like a load of pedal then a sudden release of nosewheel lock.

I wonder of the paws were a hindrance when it started to go?

Same happened a few years ago in UAE: different heli but same scenario, same cause, same ending.
It has been covered up (obviously) but the wreckage is still visible at the airport.

Yes, thatís obviously how it started but why no opposite pedal once it began yawing?

The main gearbox breaking up doesn't fill me with much confidence. I've seen a couple of roll overs, have been in one, but the gearboxes have kept their integrity.

The MGB looks intact as the shaft and beanie are still in place. The MR Head has come apart, little surprise. Fuselage retains shape and doors remain in place. Cabin door still slides open.

Sure looks like that, you can see when the nosewheel lock being released that the nosewheel swings 90degrees immediately indicating alot of left pedal...

Iím watching on my phone, but donít see the MGB breaking up?

Can't see MRGB break-up either.

Difficult to see why he didn't take any corrective action.

I think you'll find that entire post is sarcasm... :ugh:

It looks like a hardcover to the anti torque side (negative power pedal). Absolutely no response on the pedals. OR full left pedal tryin to defeat the nose wheel lock that either fails or is removed. Just can’t see why the opposite pedal is not put in. The puma goes instantly when the nose wheel over centres so cabs will spin easily once the nose wheels are in the 90 degree position. Just can’t get why opposite pedal seems absent.
