         2 . The compressor casing assembly of  claim 1 , wherein the removable cover is removably fastened to the midcompressor casing. 
     
     
         3 . The compressor casing assembly of  claim 1 , wherein the cavity is configured to prevent movement of the seal assembly in a radial direction. 
     
     
         4 . The compressor casing assembly of  claim 1 , wherein the seal assembly comprises a T-shaped member having a first projection and a second projection, and wherein the cavity has a notch adapted to receive the second projection. 
     
     
         5 . The compressor casing assembly of  claim 4 , a removable cover has a cover notch adapted to receive first projection. 
     
     
         6 . The compressor casing assembly of  claim 1 , wherein the removable cover comprises an arcuate member. 
     
     
         7 . The compressor casing assembly of  claim 1 , wherein the forward compressor casing is disposed in contact with the removable cover. 
     
     
         8 . A turbine engine, comprising:
 a midcompressor casing having a face surface and an inner surface, the midcompressor casing having a cavity formed on the inner surface and a groove formed on the face surface;   a plurality of arcuate seal segments configured to be inserted into the cavity;   a removable cover disposed in contact with at least one of the plurality of arcuate seal segments and being removably secured to the midcompressor casing.   
     
     
         9 . The turbine engine of  claim 8 , wherein each of the plurality of arcuate seal segments comprises a sealing surface extending a full circumferential length along each of the plurality of arcuate seal segments. 
     
     
         10 . The turbine engine of  claim 9 , wherein the sealing surface comprises one of an abradable seal surface, a honeycomb seal surface, and a brush seal surface. 
     
     
         11 . The turbine engine of  claim 8  wherein the removable cover is an arcuate member. 
     
     
         12 . The turbine engine of  claim 8  further comprising a forward compressor casing disposed adjacent to the removable cover. 
     
     
         13 . An assembly, comprising:
 a midcompressor casing having a face surface and an inner surface, the inner surface having a cavity and the face surface having a cover groove;   a plurality of arcuate seal segments configured to be inserted into the cavity; and   a removable cover adapted to be inserted into the cover groove, the removable cover disposed in contact with at least some of the plurality of arcuate seal segments and secured to the midcompressor casing.   
     
     
         14 . The assembly of  claim 13 , wherein the removable cover is removably fastened to the midcompressor casing. 
     
     
         15 . The assembly of  claim 13  wherein the cavity is configured to prevent movement of the plurality of arcuate seal segments in a radial direction. 
     
     
         16 . The assembly of  claim 13  wherein the removable cover is an arcuate member having a peripheral length that is longer than a peripheral length of each of the plurality of arcuate seal segments. 
     
     
         17 . The assembly of  claim 13  wherein each of the plurality of arcuate seal segments comprises a sealing surface extending a full circumferential length along each of the plurality of arcuate seal segments, the sealing surface extending a distance above and below a radially inner surface of the midcompressor casing when each of the plurality of arcuate seal segments is coupled the midcompressor casing. 
     
     
         18 . The assembly of  claim 17  wherein the sealing surface comprises one of an abradable seal surface, a honeycomb seal surface, and a brush seal surface. 
     
     
         19 . The assembly of  claim 13  wherein each of the plurality of arcuate seal segments comprises a T-shaped member having a first projection that engages a notch formed on the midcompressor casing and a cover groove formed on the removable cover. 
     
     
         20 . The assembly of  claim 13  further comprising a forward compressor casing disposed in contact with removable cover.
