The Honorable John R. Block
The Secretary of Agriculture               ~HI
Dear Mr. Secretary:                               119946

      Subject: Cost Increases, Technical Problems, and Lack of
                User Interest Make Continuation of Helistat Program
                Questionable (GAO/MASAD-83-4)

      The Forest Service is developing a lighter-than-air vehicle
 consisting of a 343-foot-long blimp envelope with a frame which
 has four helicopters attached to it.  (See enc. I.) After com-
 pleting the development program in 1983, the Forest Service then
 plans to use this vehicle, called the Helistat, to demonstrate
 that aerial logging operations are economical in steep, inaccessi-
 ble mountainous terrain.

      When the Helistat program began in 1979, the estimated net
 cost was $6.7 million--it has subsequently increased to at least
 $31.7 million. The development was to require 28 months--it will
 now take at least 41 months. In addition, significant technical
 problems exist that must be resolved before the development pro-
 gram can be completed. Because the Forest Service has not
 developed a plan for resolving the technical problems and pre-
 pared a revised cost estimate, the final cost and completion are
 uncertain.

      In our previous report on the program (MASAD-81-31, June 2,
 1981), we noted that potential users saw little practical appli-
 cation for a vehicle of this type. The lack of user support,
 coupled with the dramatic increase in program cost, makes the con-
 tinuation of the program questionable.

      We have the following concerns.

      --Estimated net cost of the program has increased
        373 percent.

      --Engineering problems have delayed the program and
        caused concern about the structural strength of the
        vehicle.
