ENG FAILURE CAUSED BY CARB ICE MAKES A FORCED EMER LNDG NECESSARY.

Narrative

PROBLEM BEGAN AT 300 FT AGL SHORTLY AFTER TKOF. ENG RUNUP NORMAL; ALL INDICATIONS IN ENG INSTS NORMAL. APPLIED FULL PWR; ACCELERATION NORMAL; ENG INSTS NORMAL. ONCE AIRBORNE; ENG RAN ROUGH; SUSPECTED CARB ICE BECAUSE THIS PARTICULAR MAKE/MODEL OF ACFT IS SUSCEPTIBLE; ESPECIALLY SO; TO CARB ICE EVEN WHEN CONDITIONS NON-FAVORABLE FOR CARB ICE. AWOS RPTED TEMP 18 DEGS AND DEWPOINT -11 DEG F (LOW RELATIVE HUMIDITY). PULLED ON FULL CARB HEAT; ENG LOST ALL PWR; AND PWR WAS NOT REGAINED IN TIME TO PREVENT A FORCED LNDG. NOT ENOUGH RWY AHEAD REMAINING TO LAND AND WITH 90 DEG XWIND AND GUSTS; WOULD HAVE BEEN DIFFICULT WITH NO PWR. PLT ELECTED TO LAND ON A CLOSED RWY NOW USED AS A TAXIWAY; AS IT WAS ORIENTED INTO THE WIND AND AFFORDED MORE USEFUL DISTANCE TO LAND. SUCCESSFUL LNDG MADE AND ENG RUNUP WAS NORMAL AFTER LNDG. EXAMINED FOR OTHER POSSIBLE CAUSE OF ENG FAILURE; NON-OBVIOUS. PLT TAXIED FOR ANOTHER TKOF; ELECTED TO USE CARB HEAT AS PREVENTIVE MEASURE AND WAS SUCCESSFUL. REST OF FLT WAS UNEVENTFUL. POST-FLT DISCUSSION WITH OTHER PLTS REVEALED SIMILAR SITUATIONS; CARB ICE IN NON CARB ICE FAVORABLE CONDITIONS; WHEN CARB HEAT APPLIED; FULL LOSS OF PWR FOR AS LONG AS 40 SECONDS. ACFT; AN SMA. I BELIEVE PLT (ME) ACTED ACCORDINGLY; AND MADE SAFE LNDG DUE TO THE CIRCUMSTANCES AND TOOK APPROPRIATE ACTIONS. POSSIBLE REMEDY -- A CARB ICE DETECTOR (NOT JUST CARB TEMP GAUGE; WHICH THIS ACFT HAS).
