## NHTSA's summary

Field Change Program: To inspect auxiliary structure around front axle for not properly executed welds On the vehicles affected by this bulletin there is a possibility that the welding bead between some tubes of the front axle auxiliary structure and the main structure is insufficient. Although these tubes are part of the auxiliary structure, it is very important that these welding beads are checked and, if necessary, repaired to prevent corrosion damage by the intrusion of water and dirt in the long term. Besides that we ask to install reinforcement plates as mentioned further on in this Bulletin. The cause of this not well executed welds can be explained by the fact that due to a manufacturing process change the tubes of the auxiliary structure were not anymore well aligned with respect to the main structure when the robot starts welding. From vehicle 42725 onwards, the manufacturing process has been modified so that these tubes are again properly welded to the main structure of the front axle. This Service Information Bulletin has been released in order to inform service technicians how to inspect for/repair not properly executed welds in the front axle area of these coaches.
