left and right hand standby fuel pump switches together with the revision of the Emergency and Abnormal Procedures sections of the AFM to advise the flight crew of the proper procedures to follow in the event of failure of the standby fuel pump to shut off.
             The Directive is issued to prevent this inadvertent operation, which could result in inadvertent fuel transfer by the left or right wing fuel system and subsequent over-limit fuel imbalance between the left and right wing fuel loads.  This imbalance could affect lateral control of the aeroplane which could result in reduced controllability.
