Narrative:
During the day I was tasked to replace a part on the aircraft. As I was replacing the part using aircraft maintenance manual (amm) 27-03-01 I hooked up a hoist that was called out for tooling in the amm. As the part was being replaced the hoist snapped causing damage to the aircraft. I notified my lead and supervisor. We took photos of the broken tooling. Our tooling supervisor took the tooling and was sending it to the manufacture to see why the tooling failure occurred. Maintenance control was notified and aircraft was placed out of service to repair damage.I believe this was a manufacture defect; but I think this tooling should be inspected at all stations to be safe.
