This report summarizes an investigation to determine the impact of the proposed revisions to airport rules at Boston-Logan International Airport regarding ground movement of aircraft by towing in lieu of taxiing as it affects the fatigue life of the DC-9 aircraft. Tests were conducted using an instrumented tow bar to determine the range of loads which could be expected to occur in service. These loads were then incorporated into a loads model which represents the Boston-Logan towing regime. This loads model was then utilized to perform analysis on the DC-9 nose landing gear and its support structure to determine the fatigue effects. Cost estimates of additional testing, inspection and replacement of affected parts is provided. The results of this investigation indicate that several nose landing gear components could be seriously affected depending upon the degree of exposure to the additional towing at Boston and the number of flights already accumulated by the part at the time the additional towing is initiated at Boston. The immediate effect on these components could be minimized by a redistribution of aircraft within the airline fleet to reduce the exposure of high-time parts of the Boston towing regime. (Author)
