## Discrepancy

DURING A FATAL AIRCRAFT ACCIDENT INVESTIGATION, INTERNAL DETERIORATION OF MIL-6000 HOSE WAS FOUND PLUGGING A VENT LINE.  THE HOSE WAS DATED DURING 1977 AND 1986.  THE AIRCRAFT WAS OPERATING ON AUTO GAS (STC'D).  THIS CONDITION HAS BEEN SEEN AND REPORTED BEFORE.  IT IS IMPSSIBLE FOR A CAR GAS USER TO KNOW WHAT IS IN THE PRODUCT/GAS DUE TO REFINERY SWAPPING OF PRODUCT AND CO-MINGLING OF PRODUCTS.  SUBMITTER STATED C/W WITH STC, NOT POSSIBLE AS IT IS WRITTEN.
