A1  MAINTENANCE APPROACH

     This machine type will be repaired to the sub-assembly level
during  on-site  maintenance  and  repair at  class  3  C.R.C.'s.
Limited  component  level repair may be  authorized  for  certain
class  2 C.R.C.'s.   Component level repair is authorized for all
class  1  C.R.C.'s,  however  a test bed may  not  be  authorized
depending on volume.   NOTE:  It may be to the C.R.C.'s advantage            
to  repair only to the sub-assembly level.   The  King of Prussia
production facility will repair to the component level.
