ABSTRACT:
A gas turbine engine plenum cover is repaired using a prefabricated repair cover SPAD. The SPAD repair cover has a spoolie boss that is aligned and attached to the body of the repair plenum cover prior to attachment to a plenum casting to form a repaired plenum chamber. Preattachment of the spoolie boss by brazing methods, as well as optional machining of a borescope hole prior to or after attachment of the repair cover, greatly simplifies the repair process, thereby reducing the time required and cost of repair.
