Rework Procedure

The initial release of this letter contained software that corrected the Engine Protection Override Switch (EPOS) issue. Since then, several other improvements have been added to the software. This service letter has been revised to allow customers to receive the new improvements as well as the EPOS solution that the letter was originally written to address. This revised letter should not be applied to an engine that has already had PI1395 preformed.
