Two flight crew were injured as turbulence hit an easyJet aircraft as it prepared to land in Milan.
One of the cabin crew suffered a broken ankle and the other severe bruising, an air accident report revealed.
They were both take to an Italian hospital after medical staff were called to meet the aircraft.
None of the 137 passengers was injured on board the Airbus A320 flight from Gatwick on January 30, according to the report from the Air Accidents Investigation Branch.
The aircraft hit “two brief but severe” clear air turbulence encounters in quick succession in decent to Milan Malpensa airport.
The report said that in pre-flight preparations, the flight crew noted that only low levels of turbulence were forecast, ”although there had been a report of severe turbulence over the Alps at FL (flight level) 220 (22,000ft)”.
The report said: ”During the descent, the flight crew asked ATC (air traffic control) if there were any turbulence reports along their intended track and were told that light to moderate turbulence had been reported.
”The commander (captain) warned the cabin crew of the possibility of turbulence and instructed them to secure the cabin. A few minutes later, passing FL220, the aircraft had two brief but severe clear-air turbulence encounters in quick succession.’
”Two members of the cabin crew were injured in the turbulence encounters so the flight crew arranged for medical staff to meet the aircraft on its arrival.
”The injured crew members were taken to hospital where one was found to have suffered a broken ankle and the other severe bruising.”
