Section IV. Maintenance instructions
2-11.1 Maintenance concept
Unit level and Intermediate Direct Support and Intermediate General Support (IDS/IGS) maintenance on the
interior lighting system Is performed onboard by barge crewmembers whenever possible.
Any IDS/IGS maintenance beyond capability of crewmembers is provided by a shore-based area support
maintenance unit. This unit also determines if depot support maintenance is required.
Intermediate support maintenance is accomplished by replacement of components or major end items.
Unless other intermediate support procedures are directed, IDS/IGS maintenance normally is provided by
an Army Transportation Corps floating craft intermediate support maintenance unit serving terminal operating area.
Components to be disposed of are processed by this unit.
Maintenance Allocation Chart (MAC) Is In TM 55-1930-209-14&P-18. For maintenance of other equipment
onboard, consult appropriate manual.
