Narrative: DATE.  First day back from days Off; started at TIME and was turned over 2 out of service aircraft; and a ferry flight.  Turnover for ferry flight was everything in order will require the inspection sign off and MFD; it was to be a 3 leg ferry due to biobore in the tanks.   Each leg requiring a new MFD (Maintenance Ferry Document).  First leg was scheduled for a XA:30 departure.  During this time I was updating logs; fielding phone calls; and reviewing ferry checklist.  Started to review ferry documents and noted that there were a few overtime items that were not documented in the logbook on logs N and 5N1. I then documented the missing items under log page N2.  Overdue items were transcribed.  Under this transaction you will find open log pages; open work control packages; and overtime items.  Aircraft was then issued MFD.  Checklist completed.2nd leg of ferry was ZZZ-ZZZ1.  Ferry arrange was prepared and sent when aircraft arrived ZZZ.  I discussed the inbound discrepancies with ZZZ;  a dual tire replacement due to one tire being underinflated.  We noted; log page N as stating one or more items have been identified as overtime or becoming overtime.  I again reviewed maintenance release and noted no change in items.  Paperwork was completed; inbound discrepancies addressed and MFD issued.3rd leg of ferry was ZZZ1-ZZZ2.  During review of paperwork in preparation for ferry; it was noted 2 additional items under maintenance release as being expired.  It was during this time I discovered that these 2 items must have expired in flight and were not in a log item or on the MFD.  Part of the Ferry checklist is to ensure time-controlled workload items that will expire by the end of the flight are documented.Task Card X and -0024 GVI (General Visual Inspection) Strut 1 and 2 Insp appear to have expired in flight.  At this point I spoke with my co-worker and we generated another log with the 2 out of time items.  I was asked if it showed due in maintenance release.  My reply was that I have been viewing out of time items under maintenance release which will show task that are currently out of time vs forecasted task.  My oversight led to expiring of time-controlled workload items in flight.  Policies; procedures and processes are area that I feel I am thorough in.  For me this is a lesson learned and something that I will not forget in future ferry flights.




Synopsis: Maintenance Control Technician reported numerous errors when completing the required paperwork for an ETOPS ferry flight with numerous flight legs; resulting in time limited items expiring in flight.
