Bulletin numbers are derived by assigning a sequential number and then appending a dash and the year of original issue. For example, bulletin “3-2000” is the third bulletin published in calendar year 2000. The date indicates the current version of the bulletin. Some gaps exist in the list because certain Engineering Bulletins have been withdrawn due to obsolescence as designs and regulations change.
