CL60 / A388, en-route, Arabian Sea, 2017

Summary

On 7 January 2017, the crew of a Bombardier Challenger en route at FL340 over international waters between India and the Arabian Peninsula temporarily lost control of their aircraft approximately one minute after an Airbus A380 had passed 1,000 feet above them tracking in the opposite direction. The Investigation is ongoing but has noted that both aircraft were in compliance with their air traffic clearances, that a major height loss occurred during loss of control with some occupants sustaining serious injuries and that after successfully diverting, the structure of the aircraft was found to have been damaged beyond economic repair.

Description

On 7 January 2017, the crew of a German-operated Bombardier CL604 Challenger en route from Malé, Maldive Islands to Abu Dhabi (Al-Bateen), UAE at FL340 in day VMC suddenly lost roll and pitch control of their aircraft shortly after an opposite direction Airbus A380-800 at FL 350 and en route from Dubai to Sydney had passed 1,000 feet above. Recovery was only achieved after an upset which included a loss of altitude of almost 9,000 feet in about half a minute during which time the left engine was shut down due to over-temperature. An emergency was subsequently declared and a diversion made to Muscat without further event. Two of the six passengers were seriously injured and two others and the cabin attendant sustained minor injuries. The aircraft was subsequently found to have been severely damaged during the upset and consequently a hull loss.
