Ice road truckers could be out of business soon. Boeing and SkyHook are developing a hybrid heavy-lift helicopter/blimp capable of hoisting a 40-ton sling load and moving it 200 miles without refueling. The JHL-40 will be capable of transporting equipment and materials to remote drilling and mining locations in the Canadian Arctic and Alaska. The helium “envelope” will support the vehicle while the four main rotors will lift the payload.

Possibly as a result of its Repair, Alteration and Fabrication Team study, the FAA issued Special Airworthiness Information Bulletin SAIB NE-08-40, which reiterates the need for companies that make parts under Parts Manufacturer Approval regulations “to support the continued operational safety (COS) of their design.” While the agency said in the SAIB that “PMA and STC parts are thoroughly evaluated for compliance with respect to any changes th

South St. Paul, Minn.-based Ballistic Recovery Systems on July 24 performed a touchdown condition test on an OMF Symphony 160 fuselage. In the test, a conforming fuselage of the Part 23 two seater–sand bagged to simulate a mtow of 2,150 pounds–was hoisted to 8.5 feet and dropped by releasing the tow cable. Although no parachute was involved, the test created a descent rate calculated for a 5,000-foot density altitude.
