What we do know is that if either or both of them floated the lack of beacon signals is an issue. If they did not float, then beacons would not have helped but clearly flotation devices would be an issue. Until one or both men are recovered, we can not answer these questions.

If designed to deploy on immersion, it obviously would not have triggered with that part of the wreckage being on land. If triggered by impact, I suppose it's possible that catastrophic damage occurring quickly enough could sever the connections between the ADELT and the relevant sensors before it was triggered. Posters on that forum also referred to other accidents where such devices had failed to deploy/transmit.

I'm posting this to try and give people an understanding of the level of detail and analysis that AAIU put in to their investigations. This report took 15 months to complete. SAR 116 will be infinitely more complex and I would expect it to take a lot longer before all aspects have been fully investigated. As happened with the Manx 2 crash in Cork, there will probably be a preliminary report issued but that may take 6 months to a year. I would urge people to read it as it may provide a balance to the fact vs speculation debate and also to my previous point that even if they are now focusing on human factors, they most certainly have not exhausted other aspects including mechanical issues.http://www.aaiu.ie/sites/default/files/report-attachments/REPORT%202017-005_0.pdf

That report won't give you anymore information than what is available right now, it won't reveal a cause.
Steve wrote: » There are a lot of people following this thread who may not be aware of the detail in an AAIU report, I was suggesting they read the one I linked to as an example to see the lengths they go into, not the prelim for 116 - I agree with you on that. In any case, it's been 30 days so we can expect that soon.
Jakey Rolling wrote: » Re manual or automatic inflation of lifejackets - there's good reason for them to be manual, as it would be nigh on impossible to escape from an upturned helicopter while wearing a fully inflated jacket ( this exercise forms part of standard offshore survival courses). Automatic inflation is more appropriate for yachtsmen or deck workers on fishing or other vessels where they are more likely to fall into open water, possibly as the result of a concussive blow.
TomOnBoard wrote: » This point highlights the extent to which the SAR crew(s) safety/ recoverability cannot rely on many of the safety devices/fallbacks that are taken for granted in boating/sailing etc. So much of the strategies and technologies relied on elsewhere is simply of limited utility in such a hostile environment as the wild North Atlantic Ocean, such as: radio beacons are of no use underwater, and can be seriously compromised on the surface due to monstrous wave heights; water temperatures are so low that hypothermia will occur quickly although mitigated by immersion suiting; ; life jackets are of limited use to a less than fully aware survivor due to the impracticality of using automatic inflation technologies; search areas are vast out there and terrain and conditions hazardous to surface rescue craft.
