ECHANICS, WORKING IN THE SANDBOX IS NO JOKE. 3AND GETS INTO EVERY NOOK AND CRANNY
AND PUTS EXTRA WEAR AND TEAR ON EVERYTHING IN ITS PATH. 4HAT'S WHY IT'S IMPORTANT TO INSPECT
EVERYTHING THOROUGHLY TO THE NTH DEGREE.
&OR EXAMPLE, THE #HINOOK &7$ AND !&4 CARGO HOOK MECHANISMS CLOG WITH SAND FREQUENTLY
AND MAY NOT OPERATE PROPERLY DURING SLING LOAD OPERATIONS.
4HEY MAY NOT CLOSE ALL THE WAY AFTER RELEASING A
LOAD. 4HEN, WHEN YOU LIFT OFF¡OR DURING mIGHT¡IT
OPENS AND YOU LOSE A LOAD. /R, THE HOOKS MAY NOT
OPEN NORMALLY OR EVEN BY USING THE EMERGENCY
HANDLE. )F THAT HAPPENS, TENSION MUST BE PUT ON
THE SLING TO FORCE THE HOOK OPEN. 4HIS CAN PUT THE
LOAD AT RISK AND SOLDIERS IN HARM'S WAY IF THE CLEVIS
COMES LOOSE AND HITS TROOPS STANDING NEAR BY.
)NSPECT AND CLEAN THE HOOKS PRIOR TO EACH
OPERATION LIKE IT SAYS IN 4ASK 16-11 OF 40 55-1528-
298-2:-18. !ND ALWAYS PERFORM THE CARGO HOOK
OPERATIONAL CHECK LIKE IT SAYS IN 4ASK 16.1.9 OF 40
55-1528-298-2:-4 PRIOR TO SLING LOAD MISSIONS.
