## Analysis

THE ACFT CRASHED ON THE NORTH BOUNDARY OF THE ARPT WITHIN MINUTES AFTER HAVING BEEN SEEN DEPARTING RWY 27. DENSE GROUND FOG PREVAILED AT THE CRASH SITE. APPROXIMATELY 1-1/2 HOURS AFTER THE ACCIDENT EXAMINATION DISCLOSD VERY HEAVY FROST ON ALL ACFT PARKED ADJACENT TO THE SPOT WHERE THE ACFT HAD BEEN SEEN PARKED FOR TWO DAYS. ACCORDING TO THE PERSON WHO DROVE THE PLT TO THE ARPT THERE WAS FROST ON THE ACFT WHEN THEY ARRIVED AT THE ARPT. HE FURTHER STATED THAT HE DID NOT SEE THE PLT REMOVE FROST FROM ANY PART OF THE ACFT EXCEPT THE WINDSHIELD. THE CARBURETOR HEAT VALVE WAS FOUND JAMMED IN THE FULL HOT POSITION. ACCORDING TO ENGINEERING DATA OBTAINED FROM PIPER THE HEAT RISE OF THE CARB HEAT SYSTEM IS 129 DEG F AT 75% POWER & 28 DEG F AMBIENT AIR TEMP. THE POWER LOSS DUE TO CARB HEAT IS 1% FOR EACH 10 DEG HEAT RISE.
