In general, we do not have the facility to access the raw QAR data on the line. In my previous experience, if we have an on-going fault that the troubleshooting is not rectifying, we may pull the QAR card or download the SAR file data, send it off to Tech Services who will review and advise of any action to be taken. The QAR is more there for reviewing flight incidents, than as a troubleshooting tool.
