The disclosure is directed to a system including a processor, a sensor interface responsive to the processor and memory responsive to the processor. The level member is rotatably attached to a mounting member that is secured to a wall. The first conductor portion is electrically connected to the first grounding point and to the common feeding point. A second bleed circuit is joined in flow communication between an intermediate stage of the compressor and aft cooling channels in the nozzle vanes to feed second cooling holes with pressurized secondary air at a second pressure less than the first pressure. A spiral or helical fastener, which is temporarily attached to the drive tube distal end, is positioned within the overtube lumen.
