## Analysis

THE PLT REPORTED THAT DURING AN ILS APCH TO LAND, THE ENG LOST POWER WHEN THE ACFT WAS ABOUT 1/4 MI FROM THE THRESHOLD. HE STATED THAT HE 'CONFIRMED MIXTURE RICH, CARB HEAT ON, FUEL PUMP ON, FUEL FULLEST TANK.' THE PLT WAS UNABLE TO RESTART THE ENG. DURING AN EMERGENCY LANDING, THE ACFT WENT THRU A FENCE, CROSSED A SUBURBAN STREET & DROPPED INTO A DITCH. A POST-CRASH EXAM REVEALED THAT THE RIGHT FUEL TANK WAS EMPTY, THE LEFT TANK HAD APRX 2 INCHES OF FUEL REMAINING & THE FUEL SELECTOR HAD BEEN TURNED OFF. IN A PRELIMINARY PHONE CONVERSATION, THE PLT INDICATED A SUSPICION OF CARB ICE, BUT THIS WAS NOT VERIFIED. THE TEMP & DEW POINT WERE 72 & 62 DEG, RESPECTIVELY. ACCORDING TO ICING PROPABILITY CHARTS, THERE WOULD HAVE BEEN SERIOUS CARB ICE CONDITIONS AT GLIDE POWER, IF CARB HEAT HAD NOT BEEN USED.
