What was found
DURING THE INSPECTION OF THE SURFACE DEICE BOOT ON THE HORIZONTAL STABILIZER, IT WAS DETERMINED THE SUPPLY LINE WAS NOT PROVIDING ADEQUATE PRESSURE TO PROPERLY INFLATE THE DEICER. FURTHER INSPECTION REVEALED THE SYSTEM PRESSURE ADJUSTED. THE LINE HAD CHAFED DUE TO LACK OF PROPER SUPPORT FROM CLAMPS AND COULD HAVE BENEFITED FROM CHAFE SLEEVING OR THE LIKE.
