Narrative:

As wkend duty supervisor; I was notified by maintenance operations to send a field trip to ZZZ to replace an ice impact panel. The maintenance operations said ZZZ mechanics would remove and replace the fan blades; ZZZ2 field trip mechanics would repair ice impact panels only. I dispatched a mechanic from the field trip list on may/xa/06. On may/xb/06 at XA00 he called and told me he was too tired to work and needed to go home. I called 2 more mechanics; informed them of the job at hand and gave them the cell phone number of the mechanic currently on the job so a job status could be given. I called the mechanic who wanted to go home and informed him relief mechanics are on the way. He said ok and that he would update them on the field trip request. Contributing factors: employee did not understand that ZZZ mechanics would remove and replace the fan blades. Supplemental information from acn 698495: a number of shift changes occurred during that time. I don't even recall seeing or meeting the individual or individuals who actually performed the repair; let alone observing him removing blades or having any knowledge of alleged blade or blades removal and reinstallation. I wish to reiterate that to the best of my knowledge the serial number xxxxx constituted all of the non-routine maintenance performed to facilitate the repair in question.
