Response: MANCHESTER REVIEWED ALL ITS DOT INSPECTION REPORTS PREPARED UP TO THE TIME OF THE ACCIDENT INVESTIGATION IN DECEMBER, 1988. THE SAME RECORDS WERE REVIEWED BY THE DOT REPRESENTATIVE WITHOUT ANY RESULTS BEING FOUND INAPPROPRIATE. MANCHESTER CANNOT CORRECT A PROBLEM UNLESS IT IS IDENTIFIED. WE HAVE RESTED CYLINDERS FROM A LOT THAT WAS NOT INVOLVED IN THE ACCIDENT, AS WELL AS TWO RETURNED FROM THE FIELD REPRESENTING THE LOT INVOLVED IN THE ACCIDENT. FURTHERMORE, WE MUST NOT LOSE SIGHT OF THE FACT THAT THE CYLINDER INVOLVED IN THE ACCIDENT DID NOT FAIL AS THE RESULT OF IMPROPER DESIGN, FAULTY MATERIAL OR FABRICATION PROCEDURES, BUT THE DIRECT RESULT OF AN EXTERNAL IMPACT. WE FEEL THAT WE HAVE ACTED RESPONSIBLY IN THE ENTIRE INVESTIGATION AND THAT APPROPRIATE CORRECTIVE ACTION HAS BEEN TAKEN. WE THEREFORE, REQUEST THAT ITEM I-90-2 BE PLACED IN A "CLOSED--ACCEPTABLE ACTION" STATUS.

Response: IT IS THE MANCHESTER POSITION THAT THE TWO LOTS OF CYLINDERS CITED AS BEING IMPROPERLY TESTED OR HAVING FAILED PRECRIBED TESTS HAVE NOW BEEN PROPERLY RETESTED WITH SATISFACTORY RE SULTS; WITHOUT KNOWLEDGE OF ANY OTHER IMPROPER TESTING PRO CEDURES OR TEST FAILURES, MANCHESTER FEELS THAT THE PUBLIC INTEREST FOR SAFETY HAS BEEN PROPERLY SERVED BY THE ACTION TAKEN AND PLANS NO FURTHER ACTION.

Response: MANCHESTER STATED IT UNDERSTOOD THAT THERE WERE TWO ISSUES TO RESOLVE REGARDING THIS RECOMMENDATION. THE FIRST CONCERNS THE FAILURE OF THE TOP HEAD SPECIMEN IN ELONGATION AND TENSILE STRENGTH FOR A 22-INCH DIAMETER 4BW 240 CYLINDER NOT INVOLVED IN THE ACCIDENT. THESE TEST SPECIMENS REPRESENTED CYLINDERS IN S/N LOT E-1604 THROUGH E-1800. THIS CONDITION WAS SUBSEQUENTLY RESOLVED IN ACCORDANCE WITH DOT REGULATIONS BY RECAPTURING AND TESTING TWO CYLINDERS FROM THE SAME LOT IN FEBRUARY 1989. REFERENCE: S/N E1678 AND E1671. TEST SPECIMENS WERE REMOVED FROM THE TOP HEAD AND RETESTED USING GUAGE MARKS OF 24T [24 TIMES THE THICKNESS OF CYLINDER WALL] AND SPECIMEN WIDTH OF 6T MAX [MAXIMUM OF 6 TIMES THE THICKNESS OF THE CYLINDER WALL]. THE VALUES OBTAINED ARE SHOWN ON THE TEST CERTIFICATES ATTACHED. THE TENSILE STRENGTH AND ELONGATION EXCEED THE MINIMUM VALUES REQUIRED. THE RECORD OF PHYSICAL TESTS OF MATERIALS FOR CYLINDERS HAS BEEN CORRECTED FOR THIS LOT OF CYLINDERS AND IS ENCLOSED. AS FOR THE CYLINDERS INVOLVED IN THE ACCIDENT, MANCHESTER IS STILL TRYING TO OBTAIN TWO CYLINDERS FROM THE RETEST PURPOSES. MANCHESTER PLANS TO DO THIS SOMETIME IN NOVEMBER 1990 AS THIS IS WHEN THE CUSTOMER CAN MAKE THE CYLINDERS AVAILABLE. THE CUSTOMER HAS BEEN ADVISED OF THE NON-COMPLIANCE OF THE DOT CYLINDERS IN THE CUSTOMER'S POSSESSION.
