When ordering repairable items, always make sure you turn in unserviceable items to depot for repair. Consider it “one in” for every “one out.”
If you have any power turbine modules (PTMs), NSNs 2840-01-503-1700 and 2840-01-286-1909 for T700-GE-701C/D engine, turn them in to depot.
Note that the PTM, NSN 2840-01-286-1909, has been replaced by NSN 2840-01-503-1700. All unserviceable -1909 PTMs will be overhauled and converted to -1700 PTMs as a new configuration.
