Narrative:

Aircraft X, flight ab, diverted from ZZZ2 to ZZZ due to #1 engine being shut down by the flight crew for a 'thrust reverser unlock' light on, per pom. Flight was diverted to ZZZ2. During maintenance, I instructed the mechanic on how to isolate the indication and lock out the reverser for dispatch under the MEL. After the aircraft departed ZZZ2, I discovered that I did not instruct them to do the engine windmill inspection. To correct this error, the aircraft was stopped at the arrival station to have the windmill inspection performed. To eliminate a recurrence, I will do the in-flight shutdown report before an aircraft departs. This report requires the windmill inspection has been reviewed.

DURING MAINT, I INSTRUCTED THE MECH ON HOW TO ISOLATE THE INDICATION AND LOCK OUT THE REVERSER FOR DISPATCH UNDER THE MEL. AFTER THE ACFT DEPARTED ZZZ2, I DISCOVERED THAT I DID NOT INSTRUCT THEM TO DO THE ENG WINDMILL INSPECTION. TO CORRECT THIS ERROR, THE ACFT WAS STOPPED AT THE ARR STATION TO HAVE THE WINDMILL INSPECTION PERFORMED. TO ELIMINATE A RECURRENCE, I WILL DO THE INFLT SHUTDOWN RPT BEFORE AN ACFT DEPARTS. THIS RPT REQUIRES THE WINDMILL INSPECTION HAS BEEN REVIEWED.
