Narrative:

The problem arose because an adel clamp cut through a torque tube. It was discovered upon landing or in-flight. Corrective action would be to place adel in another position, although when job was completed the adel clamp was not in contact with the torque tube because I had moved it to prevent any friction. The adel in question was replaced in the same confign as when it was first removed. The adel clamp was removed and refitted when replacing a defective microswitch and wire bundle.
