I also agree. 'Knee-jerk' reactions to informed speculation.

This is a/the rumour network. .

I made an educated guess to what happened and i was spot on low RRPM / heavy landing.

But all the usual suspects jump up and down like schoolboys.

Silsoe sid i suggest you get round to your AME and get him to have a look at you. DESIGN ERROR clown

The machine was G BOUT.

No doubt pilot error
No, Cylclic Flare, that is not a guess, educated or otherwise.

Whirly - Thanks. Very kind of you to step in there. I obviously was commenting about the second post, not yours PB. The AAIB can presumably do their investigations from a photo in the newspaper now.

This is not an anti-Robinson thread. This is a general point (that has now been raised by others) that we cannot and should not apportion blame so easily.

If CF ever has the misfortune of being involved in an accident, I hope his "peers" are not so quick to claim pilot error without a full investigation. If somebody had been injured or worse, would he be so quick to post?
We know these posts are read by non-aviation types including press and families. Do we need to be so quick to point the finger, even if you may turn out (after a long investigation by the real experts) to be correct?

If I may recall an earlier post about R22 blades,
http://www.pprune.org/forums/showthr...94#post1703194

"High coning angles, Engine off in the hover allowing the rpm to drop to say 75% for couple of secs coluld that kink the blade."
Doesn't sound like a very good design to me and that is you saying this could happen!

But then again I have only got that bit of knowledge from an expert!

Interesting about kinked blades though!!

you sure it wasn't G-ROUT?? G-Bout comes up as a Nelson Cri-Cri??

G-Rout probably means it was Mike * onboard. Hope he's ok.

Can you cast your expert eye on this and let us know the cause. We're still unsure;


Birdstrike, could be either an emu, penguin or a Dodo, but without a doubt.....

As this is a "guess what caused the crash" thread!
IMO this could be one of the Lynxs loss of tail rotor control which led to the crew executing an EOL which unfortunately due to the soft ground led to a skid digging in leading to it ending up on its side..... judging by the coning on the blades and the MRH pitch control rod positions... mmm or it could be a dodo

R22 helicopter crash Stockport 22ND Jan

As a high time R22 Pilot, leaving my site in Romiley, I flew to Chester to collect the Owner of G-ROUT at 9.20am on the 22nd
At this point, the owner of the aircraft, flew me back to the initial take off site. On arrival at the site, approx 10.40am, we approached the site at 150ft....in a still hover. All seemed well and as a passenger of the aircraft, I was not alarmed at the approach, but at 100ft the low rotor alarm sounded. The aircrafts tail yawed to the left. At a first glance the carb heat was full out but then looking to the right the rotor RPM was at 80% with a voilent right yaw. As a co-pilot with no duals?? At this point we were 100 ft from the ground, and all went wrong...the solution to this would have been ??........ the comments are valued here...we both walked away to tell the tale!

As a medium time R22 owner and pilot, I think you did an incredible job to walk away from that. I will not venture to offer advice, but I will read the suggestions from those vastly more experienced than myself with great interest.

Well done that man. Glad you and the other chap managed to walk away.


Don't forget to submit your accident report to cyclic_flare though.

Think I would have had a few loud words to say to the pilot coming to a hover at a 150 feet !!!! Who trains these guys !!!!!!!!

it was a bad judgement at the time, i was thinking he was doing a closed area slow decent landing of some sort as a practice, but by the time of no return it was to late 80% 100 feet with only my right hand ?

Glad you both walked, well err probably crawled away from it I bet you needed a stiff drink afterwards
Was the landing site surrounded by obstacles? is that why the owner came to a 150' still hover
I see, just read your last post

Lucky escape

Very glad you got out OK that is the most important thing - never mind the machine. The statistics do not stack up well in your favour if it goes pear shaped at over 40ft in a Robbo - so well done , I doubt many of us could have done any better.

I know it is impossible to pin the cause down without a proper investigation but do you think it could have been carb icing? What were the ambient conditions?

I only ask as I have experienced what I believe to have been carb icing in an R22 I used to own with full carb heat applied.

Congrats on the recovery, and glad you both got out in one piece. Very interesting that you have been brave enough to come on here and tell the real story. Hopefully the speculation will stop now, and the AAIB can find the cause of the low RPM so we can all learn.
