## Analysis

WHILE CRUISING AT 10000 FEET MSL, IN IMC CONDITIONS, THE PILOT REPORTED THAT POWER HAD BEEN LOST. DURING DESCENT TO 2000 FEET THE ENGINE RESTARTED AND FAILED SEVERAL TIMES BUT EVENTUALLY MAINTAINED IDLE THROUGHOUT THE REMAINDER OF THE DESCENT. PORTLAND APPROACH CONTROL PROVIDED VECTORS TO THE PILOT DURING DESCENT AND THE AIRCRAFT BROKE OUT INTO LIGHT RAIN/SNOW AT 300 FEET AGL, AND 1000 FEET FROM THE APPROACH END OF RUNWAY 06. DURING LANDING THE PILOT INTENTIONALLY SKIDDED THE AIRCRAFT, COLLAPSING THE GEAR, TO PREVENT THE AIRCRAFT FROM OVER RUNNING. THE PILOT STATED THAT FREEZING WATER IN THE ALTERNATE AIR SYSTEM PREVENTED THE ALTERNATE AIR GATE FROM OPERATING AND PREVENTED SUFFICIENT AIR TO THE ENGINE.
