13.
Maintenance
 CI=combustion inspection (flow slip, liner, transition
pitch), after 12000h
 HGPI= hot gas path inspection (flow slip, liner,
transition pitch, turbine blade, nozzle change
generator bearing, turbine bearing, all sensor(tem,
vibration) after 24000h )
 MI= major inspection (Generator rotor decoupling ,
retaining ring, generator inspection with HGPI work )
