USA– Work continues on the conversion of a 747-400BCF into a 20,000-gallon air tanker. Global Supertanker purchased all the physical assets and intellectual property related to Evergreen’s original SuperTanker except the 747-100 airframe itself, and is now refurbishing the retardant delivery system for what will be the third generation of the 747 Supertanker.

According to Bob Soelberg, the Program Manager for Global Supertanker, the C check is complete on the jumbo jet, including compliance with numerous Airworthiness Directives and Service Bulletins. All major modifications to the airframe are now finished. After the engines were ground checked at maximum power and the aircraft weighed, it was taken for a test flight in the Victorville, California area before departing to be painted in Marana, Arizona.

The eight fluid tanks, which will hold water or retardant, have been inspected, tested, painted, and mounted on cargo pallets. The air pressure tanks have also been painted and are ready to go. The complete system will be shipped to Marana and installed late in February.

The video below shows a landing gear swing test on a 747. (It is not the Supertanker 747.) In the video they tested just one or two at a time because the hydraulic unit on the ground did not have enough power to do them all at the same time.
