SELECT tl_Aircraft.Registration, tm_AircraftDutySchedules.AircraftDutyScheduleID, tm_AircraftDutySchedules.AircraftID, tm_AircraftDutySchedules.StartAirportID,
                      tm_AircraftDutySchedules.EndAirportID, tm_AircraftDutySchedules.AircraftDutyLookupID, tm_AircraftDutySchedules.StartTime, tm_AircraftDutySchedules.EndTime,
                      tm_AircraftDutySchedules.StartTimeLocal, tm_AircraftDutySchedules.EndTimeLocal, tm_AircraftDutySchedules.HasUserNotes, tm_AircraftDutySchedules.Description,
                      tm_AircraftDutySchedules.IsTraxManaged, tm_AircraftDutySchedules.BWAircraftMaintenanceNoteID, tm_AircraftDutySchedules.StartVendorID,
                      tm_AircraftDutySchedules.EndVendorID, tm_AircraftDutySchedules.OrigStartTime, tm_AircraftDutySchedules.OrigEndTime, tm_Notes.NoteTypeID,
                      tm_Notes.DateCreated, tm_Notes.NoteText, tm_Notes.isactive,
                      datediff(mi,origstarttime,starttime) as TotalMinMoved
                     
FROM         tm_AircraftDutySchedules INNER JOIN
                      tl_Aircraft ON tm_AircraftDutySchedules.AircraftID = tl_Aircraft.AircraftID INNER JOIN
                      tm_Notes ON tm_AircraftDutySchedules.AircraftDutyScheduleID = tm_Notes.EntityKeyID
WHERE     (tm_AircraftDutySchedules.StartTime <> tm_AircraftDutySchedules.OrigStartTime) AND (tm_AircraftDutySchedules.StartTime >= GETDATE())
                  and (notetext like '%This aircraft schedule was auto-delayed%')
                 
order by tl_Aircraft.Registration asc


I tried max on tm_Notes.DateCreated but didn't have any luck.

Also, you can get rid of that ROW_NUMBER() / Instance_Counter field.  It's not necessary.
