Response: (SUMMARIZED) ON 1/8/91, THE FAA SENT A COPY OF THE SAFETY BOARD'S LETTER DATED 10/19/90, TO ALL 14 CFR PART 139 CERTI FICATE HOLDERS. THIS ACTION PROVIDED THE PART 139 CERTIFI CATE HOLDERS WITH AN ACCOUNT OF THE CIRCUMSTANCES OF THE ACCIDENT AS THEY RELATE TO THE DEFICIENCIES IDENTIFIED WITH THE KOVATCH A/S32P-18 WATER SUPPLY VEHICLE. BECAUSE 14 CFR PART 139 DOES NOT REQUIRE AIRPORTS TO USE WATER SUPPLY INSPECTORS TO REQUIRE THAT THESE VEHICLES BE INSPECTED. THE FAA HAS INSURED THAT THE CERTIFICATE HOLDERS ARE INFORMED OF THE IMPORTANCE OF INSPECTING THE SUCTION HOSES ON THE WATER SUPPLY VEHICLES THROUGH THE ISSUANCE OF A LETTER DATED 1/8/91, THAT STRONGLY RECOMMENDS THAT AIRPORTS USING THIS VEHICLE AS A SUPPLEMENT TO THE REQUIREMENTS OF 14 CFR PART 139 AIRCRAFT RESCUE AND FIREFIGHTING EQUIPMENT TAKE THE NECESSARY STEPS TO COMPLY WITH THE KOVATCH A/S32P-18 TECH NICAL SERVICE BULLETIN.
