Response: 6/1/76 - LETTER FROM MTB STATING EXISTING REGULATIONS SHOULD COVER RECOMMENDATION. PRODUCT QUALITY CONTROL IS COVERED BY THE ACT ONLY IN TRANSPORTATION. 11/12/76 LETTER FROM MTB TO CHAIRMAN TODD AGREEING THAT AN EDUCATIONAL PROGRAM REGARDING QUALITY CONTROL IS NECESSARY (RESPONSE TO 10/27/76 LETTER FROM NTSB). 4/27/77 - NTSB/MTB QUARTERLY MEETING. MTB BELIEVES AN EDUCATIONAL PROGRAM TO BROADEN THE AWARENESS OF THE MANUFACTURER, SHIPPER, OR CARRIER TO INCLUDE THE IMPORTANCE OF PRODUCT QUALITY CONTROL WOULD BE FAR MORE PRODUCTIVE THAN PROMULGATING A NEW SET OF REGULATIONS. IN THIS REGARD, DR. THOMPSON OFFERED TWO SAMPLE VEHICLES THAT MTB HAD PUBLISHED TO EMPHASIZE THE NEED OF FURTHER AWARENESS OF THE PUBLIC ON PRODUCT QUALITY CONTROL.
