## Discrepancy

THIS UNIT WAS INSTALLED 12 MONTHS AGO.  THIS IS A TYPICAL LIFE SPAN.  CAUSE OF MALFUNCTION IS UNIT BEING OVERHEATED IN FLIGHT.  THEY CAN`T TURN DOWN THE HEAT BECAUSE OF THE WAY IT WAS CERTIFIED.  MOST PILOTS DO NOT KNOW THIS UNIT IS INOPERATIVE.  THE STALL WARNING HORN WILL SOUND EVEN THOUGH THE UNIT IS BAD.  (K)
