While flying in instrument meteorological conditions (IMC), the pilot reported to approach control that the airplane had suffered a loss of its vacuum system. He requested a lower altitude in an attempt to descend into visual meteorological conditions (VMC). The pilot reported being unable to locate visual conditions. The airplane departed controlled flight and impacted the terrain. The primary vacuum pump was found inoperative with fractures of the rotor and vanes. The standby system was found not capable of operation due to a restriction in the system from the migration of sealing material or a gasket, blocking a hole drilled for the installation and operation of the standby system.
Probable Cause: failure of the pilot to maintain control of the airplane, due to spatial disorientation. Factors relating to the accident were: failure of the (primary) vacuum system and a restriction in the (standby) vacuum system.
