Mechanics, the word is out. TM 1-1680-320-13&P (Nov 18), which covers the Black Hawk high-performance rescue hoist assembly, NSN 1680-01-552-3442, has been revised.
The TM went through a major revision addressing previous issues with the 2008 update. And the new revision includes more troubleshooting procedures, corrected schematics, and additional maintenance procedures for the internal rescue hoist.
Any previous manuals you have on the hoist are rescinded, so start using the new TM to perform maintenance on the hoist. If you discover any problems or issues with the revised TM, submit a DA Form 2028.
