Initial inspection and recurring inspections must be documented. Chapter 14 contains the inspection log which must be
maintained for each block. Any deficiencies noted are to be corrected before the chain block is returned to service.
The external conditions may show the need for a detailed inspection which, in turn, may require the use of non- destructive
type testing. Any parts that are deemed unserviceable are to be replaced with new parts before the unit is returned to service.
It is very important that the unserviceable parts are destroyed to prevent possible future use as a repair item and are properly
disposed of.
Note: Only qualified personnel to perform chain block maintenance.
