may be evacuated to the next higher maintenance organization. Higher maintenance levels will perform the
maintenance functions of lower maintenance levels when required or directed by the appropriate commander.

specified in the repair parts and special tools list appendix.

necessity, maintenance functions assigned to a maintenance level may, on a one-time basis and at the request

maintenance to which the function is assigned. The special tools, equipment, etc. required by the lower level
of maintenance to perform this function will be furnished by the maintenance level to which the function is

supervision and inspection of the function being performed at the lower level.
