Narrative:
I departed ols at XA00 am MST flying direct slc. Trip uneventful until approximately 40-45 mi south of slc. I was flying at an altitude of 10500 ft MSL on top first officer a scattered cloud layer in haze/fog when visibility started dropping. I proceeded to make a 180 degree turn to the right. When my attitude indicator fell over, I glanced at my directional gyro. It was spinning, so I glanced over at my vacuum gauge and noticed I had lost all pressure. By then, I looked at my turn and bank indicator and noticed that my turn had developed into a sharper turn than I thought. Immediately, I leveled my wings. By then I was in IMC conditions. I contacted slc approach on 124.30, which I had been monitoring anyway. I informed the controller that I needed vectors out of IFR conditions and informed him that I had lost my vacuum pump and which gauges. The controller gave me minimum altitude that I should stay at and gave me vectors back to visual conditions. He then cleared me to enter class B airspace, landing uneventfully. The controller that was handling the traffic that late afternoon did an excellent job.

Title: A NON INST RATED PVT PLT LOST HIS INSTS WHILE VFR IN IMC.
Narrative: I DEPARTED OLS AT XA00 AM MST FLYING DIRECT SLC. TRIP UNEVENTFUL UNTIL APPROX 40-45 MI S OF SLC. I WAS FLYING AT AN ALT OF 10500 FT MSL ON TOP FO A SCATTERED CLOUD LAYER IN HAZE/FOG WHEN VISIBILITY STARTED DROPPING. I PROCEEDED TO MAKE A 180 DEG TURN TO THE R. WHEN MY ATTITUDE INDICATOR FELL OVER, I GLANCED AT MY DIRECTIONAL GYRO. IT WAS SPINNING, SO I GLANCED OVER AT MY VACUUM GAUGE AND NOTICED I HAD LOST ALL PRESSURE. BY THEN, I LOOKED AT MY TURN AND BANK INDICATOR AND NOTICED THAT MY TURN HAD DEVELOPED INTO A SHARPER TURN THAN I THOUGHT. IMMEDIATELY, I LEVELED MY WINGS. BY THEN I WAS IN IMC CONDITIONS. I CONTACTED SLC APCH ON 124.30, WHICH I HAD BEEN MONITORING ANYWAY. I INFORMED THE CTLR THAT I NEEDED VECTORS OUT OF IFR CONDITIONS AND INFORMED HIM THAT I HAD LOST MY VACUUM PUMP AND WHICH GAUGES. THE CTLR GAVE ME MINIMUM ALT THAT I SHOULD STAY AT AND GAVE ME VECTORS BACK TO VISUAL CONDITIONS. HE THEN CLRED ME TO ENTER CLASS B AIRSPACE, LNDG UNEVENTFULLY. THE CTLR THAT WAS HANDLING THE TFC THAT LATE AFTERNOON DID AN EXCELLENT JOB.
