Whereas the probe remains to be on, the prelim report formally confirms that the “confirmatory (dope) check report of the pilot-in-command (PIC) was discovered non-negative” and that the Airbus A320 had suffered an especially uncommon a number of hydraulic failure.When the “occasion” occurred, “initially, (the plane) gained 372 ft and fell by 292 ft from its assigned flight degree of 36,000 ft…. seat belt indicators have been off. Consequently, some passengers and cabin crew suffered accidents,” the report says.
