WAKE VORTEX: Enroute A380 wake flips Challenger 604 upside down
Not an accident per se, but the aircraft (Canadair Challenger 604 bizjet) was effectively destroyed at 35,000 feet by the wake from an Airbus A380. Interesting (and scary) read:
The aircraft received damage beyond repair due to the G-forces, and was written off.
According to information The Aviation Herald received on March 4th 2017 the CL-604 passed 1000 feet below an Airbus A380-800 while enroute over the Arabian Sea, when a short time later (1-2 minutes) the aircraft encountered wake turbulence sending the aircraft in uncontrolled roll turning the aircraft around at least 3 times (possibly even 5 times), both engines flamed out, the Ram Air Turbine could not deploy possibly as result of G-forces and structural stress, the aircraft lost about 10,000 feet until the crew was able to recover the aircraft exercising raw muscle force, restart the engines and divert to Muscat.
The Aviation Herald received information that Air Traffic Control all around the globe have recently been instructed to exercise particular care with A380s crossing above other aircraft. The Aviation Herald had already reported a number of Wake Turbulence Encounters involving A380s before:
