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 HIGHWAY SAFETY BUREAU: CONTINUE ITS CONSIDERATION OF THE RECOMMENDATION CONCERNING SCHOOLBUS SAFETY MADE BY THE SAFETY BOARD IN ITS REPORT OF THE GRADE-CROSSING ACCIDENT AT WATERLOO, NEBRASKA, WHICH OCCURRED OCTOBER 2, 1967.
