If you haven’t heard, the Unit Maintenance Aerial Recovery Kit (UMARK) lifting limit criteria has been updated.
Completed MWO Means no lifting recertification required
With the completion of MWO 1-1670-260-50-3, users are no longer required to perform the five-year sling recertification. In addition, the 20 aerial lifts, 16 cumulative flight hour and 100 crane or hoist lift limitations are gone.
The MWO changed the UMARK NSNs 1670-01-454-9945 and 1670-01-501-8140 to NSN 1670-01-641-7829.
All the slings associated with the UMARK kit are condition-based maintenance items, so you maintain them using the guidance in TM 1-1670—261-23&P (Jun 16, w/Ch1, Nov 17). The slings have a 15-year service life, but no longer have lift limitations.
If you still have either of the old UMARKS, NSNs 1670-01-501-8140 and 1670-01-454-9945, they must be demilled and turned into DLA Disposition Services (DLA-DS). Follow the instructions in MWO 1-1670-260-50-3.
