FAA clears supertanker Spirit of John Muir to fly

Global SuperTanker Services, LLC has reported its firefighting B747-400, the Spirit of John Muir, has received its final safety and operational approvals from the FAA, the company said.

The company said Global SuperTanker completed the requested USFS testing and is awaiting the outcome from the Interagency Air Tanker Board (IAB).

Global SuperTanker´s converted B747-400 had previously been issued the FAA´s Supplemental Type Certificate (STC) authorizing the installation and utilization of its pressurized tanks. The FAA has now issued Federal Aviation Regulation (FAR) certificate 137, which allows Global SuperTanker to fly in revenue service. The Spirit of John Muir is now certified to operate as an aerial platform for wild land and marine firefighting, as well as oil spill remediation.

Global SuperTanker is currently working with the US Forest Service to achieve its final USFS certifications. While the aircraft awaits USFS approval, it is available not only to US states, counties, and cities, but also to overseas entities.

Flying at nearly 600 miles per hour, the Spirit of John Muir can leave its home base in Colorado Springs and reach any mission in the western United States in less than three hours. The range and speed of the B747-400 permits it the ability to arrive anywhere in the world in 20 hours with a single fuel stop.
