I think that you will find answers to your questions in Goodrich ASB No. 44301-10-15, revision No. 2.
But how can you rule the overload clutch to be technical deficienciant...?
Of the many hoist that have been overhauled at Goodrich it is the first time they have seen an overload clutch showing signs of actual wear.
Based on the findings it was concluded that the probable cause have been operations outside of the approved flight envelope and/or failure to perform maintenance activities correctly (Goodrich SIL-2013-01).
The proposed hoist overhaul interval of 200 hoist lifts would have devastating consequences. Such requirement would mean that we shall send our hoist of to overhaul once a week (!)
The cost per hoist cycle to would sky rocket to a ridiculous level.
