Delta's ship #6314 (N674US) was removed from storage yesterday (05/19) after spending over 50 weeks in the desert. I assume it takes many hours of work to bring it back to operational service. What exactly would be undertaken to accomplish this?
Also is this the next aircraft to go to Singapore for interior mods?

catching up on all the service checks and open inspections due, any Airworthiness inspections , the airplane has probably been "pickled" (preserved with covers and plugs) so the aircraft should be in decent shape as the Storage proceedures are going to arrest deterioration.. The engines will require high power runs and ground checks with all the systems exercised for leaks and operation. More than likely for a Ferry flight to where the pre-service work wil be accomplished..The work would not be a major deal unles the airplane had sustained damage.as even corrosion is slowed out in the desert where it's hot and Dry

Why is it headed to ANC? Does Delta do a lot of their maintenance there, or is that where they usually do the procedures to put stored aircraft back into service? Or is it going somewhere else after it lands in ANC to have all of that work done?
There are two mods due out of SIN soon. Flightaware shows N668US enrte from JFK-NRT and then to SIN today and later tonight. It's possible that 674 could go nonstop from ANC to WSAP (PayaLebar) as one of the aircraft out of mods went the reverse route awhile back. The SIN-NRT flight on the 22nd shows a modified 744.
Minor question: why would it stop in Phoenix on the way to Anchorage? If it's just going to be a positioning flight anyway. Would there be any paperwork or maintenance issues that could be done there but not at Marana?

Most likely businesswork that DL had to do that they could do at PHX. Also, a lot of planes stop over at PHX before going to Marana. Maybe better fuel services as well for the flight.

With the subject aircraft needing four powerplants installed and several systems probably needing systems flushed and seals checked, I would imagine that one or more LAF(s) - local acceptance flights - need to be accomplished prior to turning the equipment loose for a third if tge way or so journey around the world.
Some of the previous comments have tried to explain that there is more than towing to the flight line, adding crew, and filing a flight plan.
I have no knowledge of how Delta does this return to service of stored equipment, but I have participated in gathering powerplants to enable several DC10s to be flown from the storage facility to a vendor modification facility.
anyway, my 2 cents. So starting the ferry to the vendor facility from PHX makes sense.

I would be curious to know if the engines were removed prior to long-term storage on this aircraft. I know that when BA returns their B744s from MZJ to CWL, they take several weeks of maintenance work before returning to service; perhaps they are doing either a C or D Check after their long-term storage. I know that they get repainted after all that time in the sun as the paint definitely fades.
