I took over Aircraft X which was scheduled for a ferry flight later that day from ZZZ to ZZZ1 for storage.  I started reviewing the logbook to find out which overtimes needed to be added to ferry permit; which items needed to be addressed before departure and any other items required before ferry could depart.  I found approximately 4-5 additional items that would be overtime and proceeded to make the open write-ups required and lock log pages for the ferry.  We also [were working] off of for deviations allowed for returning the aircraft to flying condition after storage.As part of this the most notable deviation allowed was the allowance to place (5th stage check vlv inspection) on DIP (Deferred in Place) for 5 cycles and placing one engine hi stage vlv on either MEL XXXXX or XXXXY.  This aircraft already had MEL XXXXY applied when I took it over; the DIP was not created yet.  After a thorough review of all log pages created; items I created; review with planning of overtime items and making sure all required log pages were locked for the ferry; which took over an hour; everything appeared to be in order.  Except for the fact I still hadn't started a log page for placing a DIP on accomplishing the FCD inspection.  Approximately an hour before schedule departure time we created a DIP on Log page for accomplishing remaining steps for AMM XX-XX-XX.  Once ZZZ stated they were done with all work required; I did one last review and everything appeared to be in order so the MFD was sent to the aircraft.  Approximately 45 minutes after the aircraft departed on it's ferry flight; it finally dawned on me about the DIP required and I wasn't sure if it had been accomplished.  I went back and searched DIP log pages and all closed log pages looking to see if it had been accidentally closed; it had not; and was determined the log page was never created and did in fact get missed.At no time was the safety of the aircraft in question so I planned to make the writeup and place it on DIP once the aircraft arrived in ZZZ1 for storage.
