On 2 February, an Airbus A380 in the cruise at night at FL 330 encountered unforecast clear air turbulence with the seatbelt signs off and one unsecured passenger in a standard toilet compartment sustained a serious injury as a result. The Investigation noted that relevant airline policies and crew training had been in place but also observed a marked difference in the availability of handholds in toilet compartments provided for passengers with disabilities or other special needs and those in all other such compartments and made a corresponding safety recommendation to standardise and placard handhold provision in all toilet compartments.
