1. GENERAL
Preventive maintenance checks are limited to external inspections and functionality checks of the UMARK
components. Service is limited to cleaning and lubrication when applicable. Repairs are limited to replacement of
quick-release pins and their associated lanyard assemblies. Assemblies and subassemblies may be replaced as
authorized by the Maintenance Allocation Chart (MAC) in Work Package 0028 00, and requisitioned as specified
in the Repair Parts and Special Tools List (RPSTL), Work Packages 0029 and 0030 00. Table 1 identifies the
UMARK preventative maintenance checks and services.
2. PRE-USAGE INSPECTION
WARNING
To prevent catastrophic failure do not use the UMARK
kit if its record log indicates 20 or more uses.
NOTE
Ensure each aircraft recovery (actual flight lifting) is
annotated in log. Once a single UMARK kit reaches 20
actual lifts, call Aviation Ground Support Equipment office
(SFAE-AV-AS-AG) at (256) 876-5145 or (256) 842-9947,
and turn in UMARK kit for post field analysis. Analysis is
also conducted at 40 and 80 lifts for first kit usage only.
This analysis is only for first kit reaching 20, 40, and 80
lifts. Normal analysis is visual as described in Table 1.
Each UMARK kit contains a usage log that shall be annotated after each usage. Do not use the kit if the usage log
indicates 20 or more uses. Upon reaching 20 actual lifts call Aviation Ground Support Equipment office (SFAE-AV-
AS-AG) at (256) 876-5145 or (256) 842-9947, and turn in UMARK kit for post field analysis.
