SSBJ UPDATE: Elsewhere in this issue (“In The Works,” page 78) is word of Sukhoi’s continuing work on feasibility studies on the S-21, a supersonic business jet that, according to the company’s general director of civil aircraft, could not appear before 2010 or 2012.

Gulfstream Aerospace hosted a NASA F-15 in Savannah, Ga., on February 14 for an aerial demonstration of its Quite Spike telescopic nose spike installation. If Gulfstream were ever to decide to launch a supersonic business jet, it would have to employ some means of suppressing the sonic boom while flying over land.
Mach 1, a Southern California aircraft broker, and two of its principals, Brian Doherty and John Mouyos, plan to appeal a jury’s decision that they are liable for fraud, according to their attorney. A Southern California Superior Court jury recently ordered the defendants to pay more than $30 million in damages to Jet Source, an FBO and aircraft sales firm at McClellan-Palomar Airport in Carlsbad, Calif.
Boundary Layer Research, the Everett, Wash. company that developed winglets for the Beech Duke some 10 years ago, is now designing winglets for King Air 200s and 300s. A prototype has been flying since late last summer. An announcement sent in December to King Air operators to gauge their interest in such a modification garnered an “overwhelming” response, claimed company president Bob Desroche.
MITSUBISHI MU-2B-35, HILTON HEAD, S.C., AUG. 1, 2001–The NTSB determined that the probable cause of the accident was the improper maintenance/installation and inadequate inspection of the airplane’s flap torque-tube joints during routine maintenance by company maintenance personnel.
A new control surface could reduce induced drag on commercial and business aircraft by up to 14 percent, resulting in fuel savings of more than $400 million per year across the entire U.S. air transport fleet. So claims Utah State University aeronautical engineering professor Warren Phillips, who recently introduced the devices, which he calls “twisterons.”
Cessna announced today that it is partnering with Winglet Technology of Wichita to offer the company’s patented elliptical winglets as a retrofit later this year for in-service Citation Xs. Though flight testing won’t begin until later this summer, Winglet Technology president Bob Kiser told AIN the design has been shown to “significantly improve performance” on hot days at higher elevations.
The Australian Transport Safety Bureau (ATSB) listed it as merely a serious incident but considered it significant enough to issue a full report. The incident involved the loss of control a Saab 340 experienced when it encountered icing. There were no injuries and no damage to the aircraft, but the pilots did not recover from the loss of control until the aircraft was only 112 feet above the ground.
In the year before April 26, 2003, when Sino Swearingen’s number-one SJ30-2 prototype crashed after entering an uncommanded and unrecoverable right roll during high-speed flutter testing, company engineers were attempting to deal with lateral stability issues with the twinjet, according to the NTSB’s recently released factual report on the accident.
