Mechanics, the T55 section of PM ATE (Advanced Turbine Engines) is working on adding steps that will affect over 90 troubleshooting work packages (WPs) in a future revision of the engine IETM, TM 1-2840-265-23&P (Apr 21).
 
Essentially, the work packages will be changed to read:

While troubleshooting engine faults using the TM troubleshooting work packages, it’s recommended the maintainer perform the following steps early in the process:
 
  • Identify the related electrical connectors and cannon plugs.
  • Remove, inspect for corrosion, clean; then re-install them per TM 1-1500-323-24 (Apr 14).
  • Retest system.
  • If the fault still exists, continue with troubleshooting using the appropriate work package in TM 1-2840-265-23&P (Apr 21).
