However, the engineer failed to reset it to "auto" after completing the checking.Īfter the aircraft was returned into service, the flight crew overlooked the pressurisation system state on three separate occasions: during the pre-flight procedure, the after-start check, and the after take-off check. In order to carry out this check without requiring the aircraft's engines, the pressurisation system was set to "manual". They requested a full inspection of the door.
