ATA 78

When loose rivets are found in the “5000” series engine inlets, please refer to Chapter 54-30-00 page 802 for instructions on replacement. Pay CAREFUL attention to the little detail that tells you that the rivet will STAKE high. The rivet head will NOT be flush so do not try to make it flush. The skin is not thick enough to do that, so in a few hours the rivets are loose again, with no material left in the “D” ring to replace them.
