Yes I agree, it will point you in the direction of where to look, just a shame so much is ash and may have destroyed the cause. Hopefully they will be able to ascertain what triggered the events that unfolded to prevent any reoccurrences.

I would love to see how they go about it, because would removing the remains to a site to examine them lose evidence when ash is moved? As the ash may indicate sources of fire etc, mind you would bad weather also destroy evidence? Fascinating stuff.

Having flown that airframe numerous times, itching to find out what happened!

So, oldbeefer, in view of your familiarity with this particular cab, can we take it that, despite the RAF's and Cobham's lack of assurance, it did not have FDR/CVR?

Some rather rusty metalwork very close to the scene. A hazard such as that could be difficult to see when putting the aircraft down in a hurry. I wonder if there were other bits of metalwork at the accident site.

Not much margin for error. Identifying and approaching that peak, only one chance to put it down successfully I imagine - coolheads and teamwork vital. You'd hate to be stuck in the back though. Any studes on board? Great learning opportunity!

All Canadian Griffens have a CV/FDR and an early generation HUMS. Bell has two CV/FDR and a modern HUMS kits available. I only know the HUMS is not fitted.

7 yrs out of date, but back then there was no FDR, just a HUMS. There was talk of a simple CVR based on a solid state memory, but don't think either would survive a fire like that.

RE FDR/CVR
 
The DHFS Griffins (412's) do have a CVR.

A while back when trying to investigate the cause of an engine that had been overtemp'd, they pulled the CVR. It records approx 4 hours of intercom and cabin sounds IIRC. To my knowledge it doesn't have a FDR.

Having thousands of hours in the machine I'm at a loss to understand what may have brought about an accident such as this. Will be interesting to learn. With tongue in cheek, some one drop his cigar, or a mobile phone decide to have a melt down?

Glad everyone is OK and as for buffing out, granite is pretty resilient and a good rain shower and you will never know it was ever there.:O

I hope they were able to drum up enough cash between them to get the train back down the mountain, or some marshmallows to toast. :E

It was on "Yr Aran" not Snowdon, so they had a downhill walk, it was a nice day though. A FWD could just about get up there. I have been there and done it on foot.

Looks like they are still removing melted aluminium this Tuesday, if the Notams are anything to go by.
Saw a Chinook, with underslung hook mechanism, returning towards Shawbury or Cosford a couple of days ago.

emergency airworthiness directive

Seems the similar AB412 is having trouble with it's combining gearbox - original EAD from before this accident.

The Sultan 17th Aug 2016 21:56

Gypsy

It states the main transmission which is built by Leonardo or a sub for AB412's. B412's have Bell transmissions. No link.

Ta. I knew someone would know.

A good job by all involved getting it off of there, an interesting location, most importantly of course is that all crew got out safely.

Shackman 14th Sep 2016 18:05

Following this accident, the skies round here have been extremely 'Griffin Free' until this evening - one airborne on what looks like an airtest. After an apparent grounding, any news yet on the original cause.

MapleTopGun 30th Sep 2016 04:04

Any more speculation, or factual updates yet?
