We normally don’t report on individual aircraft incidents here, because the causal factors are related to a very narrow set of unique circumstances.
This instance is different, and should be of concern to all operators.
A Challenger 604 at FL350 operating from Male-Abu Dhabi passed an A380 opposite direction at FL360, one thousand feet above, about 630nm southeast of Muscat, Oman, over the Arabian Sea.
A short time later (1-2 minutes) the aircraft encountered wake turbulence sending the aircraft into an uncontrolled roll, turning the aircraft around at least 3 times (possibly even 5 times), both engines flamed out, the aircraft lost about 10,000 feet until the crew was able to recover the aircraft, restart the engines and divert to Muscat. The aircraft received damage beyond repair due to the G-forces, and was written off.
An official report is to be published by the German BFU. In the interim, the complete set of circumstances can be read at Aviation Herald.

Most aircraft don't have a large wake turbulence pattern to avoid, so they can get away with the RVSM of 1,000 feet. The worst, prior to the A380, was the 757, which had an unusual wake turbulence for an aircraft that size. For an aircraft the size of a 604 to get flipped, the A380 has to have a much bigger wake turbulence than expected.
