On July 13 the 737 that Coulson Aviation has been converting into an air tanker made its first drops. In this case it was a series of water drops by Tanker 137 while flying out of San Bernardino, California.
Britt Coulson said, “The 4,000 USG RADS-XXL/2 performed perfectly as did the airplane. Our flight crew couldn’t have been happier with the handling characteristics and our split tank worked as designed with no CG shift during the drop.”
Next week they will finish flight testing with the FAA, and will soon begin static tests of the tank system. They are working with the Forest Service to schedule the grid test.
Mr. Coulson expects Tanker 137 will be ready to fight fire in August.
