TEWS Tactical Electronic Warfare System
TEWS Tactical Electronic Warfare Squadron
TEWS Tactical Effectiveness of Weapons Systems ), NSN 4940-01-514-0087, to wash helicopter engines.
The word is in aviation maintenance information message (MIM) GEN-MIM-06-004. It approves using the TEWS for washing and rinsing UH-60, AH-64, and OH-58 engines. The TEWS is added to the AVUM AVUM Aviation Unit Maintenance No. 2 shop tool set. It replaces the universal wash unit, NSN 4920-01-185-6215.
You can still use the universal wash unit for all T-700 engines, so don't get rid of it.
Before washing any engine, check out the engine cleaning procedures in the appropriate engine TM for each bird, and the commercial TM for the TEWS.
For the detailed scoop, check the MIM for info on authorized adapters that each helicopter engine uses.
