Is it a low-flying airplane or a high-flying boat? You won’t be seeing one of these flying over the Kansas prairie, but if you need to travel over the high seas in the future, you may end up in one of Flightship Ground Effect’s wing-in-ground-effect (WIG) craft.

Owners of some 360 U.S.-registered Mitsubishi MU-2Bs won’t be required to install newly designed flap torque-tube joints, as proposed last September. Operators have been required to perform repetitive inspections of the joints under an AD issued in 1988, and the FAA found that there have been no service difficulty reports indicating cracks in joints for current design parts since that directive.

The termination of the agreement between Eclipse Aviation and Williams International, announced the day before Thanksgiving, is seen as a major setback for the Eclipse 500 very light jet program by many observers– particularly (and predictably) by the battalions of skeptics who have questioned the viability of the program since it was revealed in March 2000.

Carson Helicopters of Perkasie, Pa., has been granted FAA certification for new main rotor blades for the Sikorsky S-61. The design incorporates two airfoils and 12 degrees of twist, giving the venerable Sikorsky workhorse 2,000 pounds more lift in a hover and adding 15 knots to the cruise speed compared with the standard metal blades at the same power settings. Carson has signed a contract with NASA for exclusive use of the airfoils.
