Background:

This AD results from several reports of pump chamber failure.  The actions in this AD are to prevent vacuum pump failure or malfunction during instrument flight rules (IFR) flight that could lead to loss of flight instruments critical for flight.  The loss of flight instruments could cause pilot disorientation and loss of control of the aircraft.
