The primary objectives of this program were to assess the accident data gathered from various sources and to determine whether the existing cargo tank specifications in 49 CFR Part 178 need to be revised. A literature search for available cargo tank accident data was conducted, accident data was compiled and analyzed, and recommendations for revision to some sections of the standard were made. In particular, it was concluded that there is a need to improve the MC 306-type standards to reduce the high frequency of leakage in cargo tank overturn accidents. Under a contract modification, horizontal pipe loading, vertical roof loading, and actual tipover tests were conducted to determine the modes of structural failure that result in cargo leakage. Further research, including the collection of detailed accident damage data, and the conduct of additional overturn tests on representative tanks, was recommended to provide the data upon which to base specific standard revisions.
