I have seen this a number of times. The guys biggest mistake was where he tied the rope. If it had been on the hook he might have gotten away with it if done very carefully. By hooking it by the door they didnt have a chance what so ever.
I say this based on 13 years of experience working with external loads under helicopters. Jet Rangers cant really do much.

Fly it like its a rental...

And if his insurance company had any questions, I'm sure the video cleared it all up.



I was going to take up Origami, but someone said the local club folded.

That's what known as a 'dynamic rollover'. Happens when the rotor is displaced at a greater rate than the controls can match. Also happens when a heli 'hangs' a skid, as on uneven terrain. Sad to watch.

Flying helis since gyros had springs.

it seems as if he had have tied the boat to the heli near the center, instead of on ONE skid, then it wouldn't have pulled the heli to the side so much and put him in. also....if he was a bit slowed on the power and gave the boat a chance to speed up and reduce drag somewhat, then MAYBE he could have gotten away with it. But otherwise i would have though, that if someone can fly a heli like that, then they should have had enough common sense not to do something like that.

Not meaning to sound mean .....but if the pilot didn't survive then i would be forced to walk onto his grave and laugh my Ars off at him.

it seemed like it would have worked, but he tried to go WAY too fast!! Did you see that boat get up on plane!!

If there was no way to hook it in the center, they could have at least tried flying side ways

I think he stalled the tail rotor. Too much torque on the main blades and not enough tail to keep up. Should be something you learn when getting your rating.

This is the correct analysis. It is also correct that the helicopter encountered a dynamic rollover, after the line was taut, which could not be countered by opposing cyclic. However, there are a lot of other alarming "best guesses" and "half-truths" on this thread, which are no better than the "best guess" and assumptions on the part of the helicopter crew on the video. Helicopters can tow things, and the JetRanger is certified to carry external loads, but require care, and knowledge, as well as requiring additional training and a FAR Part 133 External Load (in the US) certification to perform external loads. I would highly suspect that if anyone was asked before watching the video if towing with a helicopter is possible, I would suspect that most people would say yes. Only after the crash does everyone conclude that "what a dumb$#!+" and the like and how it was done incorrectly, and how they could have done it better. How many spectators to our hobby say the same thing after we wreck?

To support my point, flying sideways would not make a difference; the result would be the same. Also, the helicopter did not run out of tail rotor authority or stall the tail rotor.

Don't know why the modelers suddenly know more than rated pilots on this one.

hey i jsut made an observation. I'm not saying i know everything about full scale helis.

I dont think it would have dragged the boat under cuz i'm sure they unhooked the rope after the heli went down....

I do hope that everyone made it out of the heli though.

My apologies. Just a lament taking a guess at it. Didn’t mean to offend any of the experts.

Read all about dynamic rollover HERE

"Irrespective of the environment, dynamic rollover can happen to any helicopter pilot. The U. S. Navy SH-60B NATOPS (Naval Air Training and Operating Procedures Standardization) manual states, "The insidious aspect of dynamic rollover is that the roll rates which precipitate it are within the range the pilot would normally allow in flight." Put another way, this statement says that a helicopter could be placed in a rollover situation well before the pilot recognizes it."


There's tons of videos demonstating this in action. One that I vividly remember is a helicopter snagging it's landing gear in a railing while landing on a ship. Amazing how fast it goes over...

rob10000 is right , it was dynamic rolover that caused the crash. But however it wasnt what started it. Stupidity did. This is dynamic rollover in a nutshell.

I dont think it's dynamic rollover.

I think he would be able to recover the situation if he would have DROPPED the pitch. The tension on the line would drop, returning him cyclic control to put the heli straight.
With dynamic rollover as depicted (with heli on the ground), it seems you dont have this possibility.

If he dropped the pitch he would have only been swimming a few seconds sooner.
