Air Crash Investigation ---- Helicopter Down ---- Part 5

Video Title :	Air Crash Investigation ---- Helicopter Down ---- Part 5
Description :	Sixteen oil rig workers' and two pilots' lives hang in the balance when their Super Puma helicopter is struck by lightning in a storm while flying to the Brae oilfield. The lightning strikes the tail rotor and it fails. The pilots perform an emergency autorotation and ditch in the sea. Everyone on board gets on a life raft, which is overcrowded and leaking in giant swells. Despite the conditions, the workers and pilots are rescued. The lightning struck due to the composite materials in the rotor blades, raising concerns among the investigators; more than 50% of the structures of the Airbus A350 and the Boeing 787 then being developed are slated to be composites, while the Airbus A380 is designed to be 20% composites.

i work offshore in the north sea, the possibility of this happening never leaves my mind

Yes, we know that from the previous parts.

We already know. You don't have to keep saying it. -_- It's quite annoying now.

Thanx for posting this Sasmaster12345! I love ACI and I haven't seen this one before!

Boeing 787 were also made from composite carbon too!!

And thats my major concern with them... this whole issue of read across or whatever im sure has happened to some extent with them... there was a boeing engineer who had expressed concerns about the safety of the new materials... was he perhaps referring to the electrical conductivity of the carbon fibre? Either way I don't want to fly on the 787 for the first couple of years as I don't trust them one bit.

Even Boeing 777 contain 50% of composite material. But, Boeing 787 contain 85% of composite material!!!

the reason the helicopter went down was because the rotor became unstable after a small part of one of the blades blew off after the blast, about 100g as they say. The composite materials on planes are mainly the bodywork, not the engines and therefor you won't be experiencing anything like this on a plane.

This is a fascinating documentary. Thanks for uploading!!!
