Safety Recommendation H-71-033A
Details
Synopsis: INDICATIONS THAT THE STRUCTURAL ASSEMBLY OF SCHOOLBUS BODIES M BE INADEQUATE WERE FOUND AND REPORTED BY THE SAFETY BOARD IN A GRADECROSSING ACCIDENT WHICH OCCURRED OCTOBER 2, 1967, AT WATERLOO, NEBRASKA. THAT ACCIDENT SHOWED THAT MAJOR ELEMENTS OF THE SCHOOLBUS BODY HAD SEPARATED CLEANLY UNDER CRASH FORCES. THIS SEPARATION INVOLVED HIGHCRASH FORCES PRODUCED BY THE COLLISION BETWEEN A TRAIN AND A SCHOOLBUS. THE SEPARATIONS OCCURRED WHERE FASTENERS USED TO ASSEMBLE MANY ELEMENTS OF THE SCHOOLBUS WERE FEW AND WIDELY SPACED. BECAUSE NO OBSERVATIONS OF INJURIES WERE MADE, IT WAS NOT POSSIBLE TO DETERMINE WHETHER THE SPACING OF THE FASTENERS CONTRIBUTED TO THE FOUR FATALITIES IN THAT ACCIDENT. SINCE THAT TIME, THE SAFETY BOARD HAS REVIEWED TWO ADDITIONAL ACCIDENT REPORTS IN WHICH THERE IS SUFFICIENT INFORMATION TO RELATE CERTAIN FEATURES OF THE SCHOOLBUS STRUCTURAL FASTENINGS TO THE INJURIES.
Recommendation: THE NTSB RECOMMENDS THAT THE NATIONAL EDUCATION ASSOCIATION AND THE SCHOOLBUS MANUFACTURING INDUSTRY: ADOPT A POLICY OF USING FASTENING METHODS WHICH INHIBIT THE RAISING OF SHARP EDGES AND WHICH PROVIDE MUCH GREATER EFFICIENCY OF JOINTS TO PREVENT THE DISINTEGRATION OF SCHOOLBUS BODIES. THIS POLICY MIGHT WELL BE IMPLEMENTED BY VOLUNTARY SPECIFICATIONS ADOPTED BY THE NATIONAL EDUCATION ASSOCIATION AND USED BY SCHOOLBUS PURCHASERS AND MANUFACTURERS.
