Narrative:

Runway 1/19 was closed by a king air with collapsed gear. Humidity was high, outside air temperature approximately 42 degrees F. After approximately 1 hour flight in VMC, I was cleared to land straight in on runway 24. Engine ran smoothly and no problems noted. Carried power and full flaps to runway. After landing and pulling throttles to idle, engine quit. I was able to exit runway but not able to drift past the hold short line. As the other runway (1/19) was closed the airport was closed until I manually towed plane past the hold short line. Engine restarted easily after about 30 mins of waiting. Deduction -- carburetor ice. Comment: temperature and humidity ideal for carburetor ice. No evidence of ice found during cruise or approach. Piper pilot operating handbook does not recommend carburetor heat during approach. I have called lycoming and they agree that carburetor heat is not necessary. However, this has happened before, to both me and other piper pilots. Perhaps the pilot operating handbook should be amended to recommend carburetor heat on approach. Carburetor ice can form on warm humid days. Had engine quit earlier, this story might have ended differently.

Original NASA ASRS Text

Title: A PA28 PLT DISCOVERS THAT CARB ICE CAN OCCUR EVEN WHEN THE TEMP IS WELL ABOVE FREEZING.

Narrative: RWY 1/19 WAS CLOSED BY A KING AIR WITH COLLAPSED GEAR. HUMIDITY WAS HIGH, OUTSIDE AIR TEMP APPROX 42 DEGS F. AFTER APPROX 1 HR FLT IN VMC, I WAS CLRED TO LAND STRAIGHT IN ON RWY 24. ENG RAN SMOOTHLY AND NO PROBS NOTED. CARRIED PWR AND FULL FLAPS TO RWY. AFTER LNDG AND PULLING THROTTLES TO IDLE, ENG QUIT. I WAS ABLE TO EXIT RWY BUT NOT ABLE TO DRIFT PAST THE HOLD SHORT LINE. AS THE OTHER RWY (1/19) WAS CLOSED THE ARPT WAS CLOSED UNTIL I MANUALLY TOWED PLANE PAST THE HOLD SHORT LINE. ENG RESTARTED EASILY AFTER ABOUT 30 MINS OF WAITING. DEDUCTION -- CARB ICE. COMMENT: TEMP AND HUMIDITY IDEAL FOR CARB ICE. NO EVIDENCE OF ICE FOUND DURING CRUISE OR APCH. PIPER PLT OPERATING HANDBOOK DOES NOT RECOMMEND CARB HEAT DURING APCH. I HAVE CALLED LYCOMING AND THEY AGREE THAT CARB HEAT IS NOT NECESSARY. HOWEVER, THIS HAS HAPPENED BEFORE, TO BOTH ME AND OTHER PIPER PLTS. PERHAPS THE PLT OPERATING HANDBOOK SHOULD BE AMENDED TO RECOMMEND CARB HEAT ON APCH. CARB ICE CAN FORM ON WARM HUMID DAYS. HAD ENG QUIT EARLIER, THIS STORY MIGHT HAVE ENDED DIFFERENTLY.
