This is a ørintscreen of a video tanken 1.30 mins before the actual crash. Are there any errors showing up in the panel? Ibb.co/hLcnJqJ

Can't see the VSI but doesn't 8FLI for 80kts/10° AOB seem like more power than necessary? Nose down attitude suggests the power isn't for a climb (that's how I interpret it).
(I'm alluding to potentially high disc loading and servo transparency with this question) |

Looking at the pic they show, there is significant damage to the couplings. More than I have ever seen. And I have dealt with many sudden stoppage instances over the last 17yrs of component overhaul and repair.
I have alot of questions on what I see here, and find it hard to believe that bolts could have fallen out, although it is possible in a bad case of the swiss cheeze holes lining up. I believe the engine was ripped from the airframe in this incident and gives pause to some of the damage seen as secondary. The reason I say that is because they show the aft driveshaft coupling torn apart, yet the tail rotor looks intact in the one picture. The liaison tube also bears significant secondary damage consistent with forced removal. Like I said, there is alot of questions still, especially since the ASB came out to look at these bolts. Are they a cause, or is it secondary damage as well. |

this a/c should have the latest mod i think. well beyond the blue head bolts..
there is longer bolts, the 12pt nuts and the higher torque loading now. if the bolts sheared thats one thing, but if they were loose for so long the nuts came off, or wore thru the bolts enough to disconnect, then theres some serious human factor errors at play from alot of levels |
Final report on the accident is published
The final report on the investigation of the accident near Alta on the 31st of August 2019 from the Norwgian safety investigation authority (NSIA) was published yesterday.
The translated version is here. "As a result of this investigation the NSIA submits 12 safety recommendations addressed to EASA, CAA-N and Helitrans AS, the helicopter operator. They concern measures to prevent servo transparency, training and safety of commercial sightseeing flights, survival aspects, including crash resistant fuel system and use of helmets, and requirements of lightweight flight recorders." |
