1) Engine hoist. When engine was lowered after removal; it was found that the cable that goes around drum is kinked and separating. 2) Engine sling. When setting up the sling for removal of engine there were no instructions on how to make adjustments to sling to achieve proper balance. After talking to several other mechanics and numerous experiments and using the information provided for the sling referenced in the Gulfstream G200 Manual; we managed to get the sling connected properly. (No Instructions for this sling). 3) Engine stand. After removal of engine; while attempting to place engine on stand for safety concerns about cable and due to length of time engine would be off [aircraft]; we found that there are no Stand fixture brackets compatible with these stands. So the engine is hanging on hoist right now. Engine hoist: 1) Even though there is an equipment inspection before use card; if the cable is damaged underneath the other cable windings like this one; it will not be seen until the cable is let out. Is there too much cable wrapped around the drum. 2) Engine sling. Get some instructions made up for the sling that is being used on the Pratt-Whitney (P/W) 306A engine; so everyone can make adjustments. The engravings as to engine type are nice; but if something was reversed like the aft mount chain bracket and you did not know better; then it could cause some problems. 3) If Management wants; say; the engine removed; shouldn't the equipment be in place to do the work? Referencing the engine stand mounting fixtures; why are there none here in the hangar? Inspection. Engine hoist cable frayed.
An Inspection Authorized (I/A) Aircraft Maintenance Technician (AMT) reports that after removal of the Left PW 306A Engine from a G200 aircraft; they found the sling hoist cable was kinked and separating and the Engine Stand did not have compatible fixture brackets to lower the engine on to. As a result; the engine was left hanging on the hoist.
