The FAA last month released Airworthiness Directive 2007-10-15, which requires that operators of all 765 U.S.-registered Cessna Caravans install low-airspeed awareness systems at a cost of about $8,200 per airplane. The AD also requires that Cessna-issued AFM Supplement S1–which addresses operations in icing conditions–be incorporated into the Caravan AFM.
FAA Airworthiness Directive 2007-10-15, effective June 21, requires that operators of all 765 U.S.-registered Cessna Caravans install low-airspeed awareness systems at a cost of about $8,200 per airplane.
Pilatus PC-12, Bellefonte, Pa., March 26, 2005–The NTSB determined the probable cause of the crash of the PC-12 on an ILS approach to University Park Airport, State College, Pa., was the pilot’s failure to maintain sufficient airspeed to avoid a stall, which resulted in an inadvertent stall and spin. Factors also included the pilot’s failure to follow procedures/directives and clouds.
The NTSB has published the final report on the Icing-related crash of a Cessna Citation 560 that stalled during approach to Runway 26R at Pueblo Memorial Airport on Feb. 16, 2005. The two pilots and six passengers were killed.
By the middle of last month, Eclipse Aviation had delivered two airplanes to individual owners and three to air-taxi operator DayJet, which is using its airplanes for pilot training. DayJet plans to certify installation of a stand-alone attitude indicator to make its first airplanes Part 135 compliant until Eclipse receives certification for a third ADAHRS.
2003–The NTSB cited the flight instructor’s inadequate supervision of the flight of Grand Aire Express’s Falcon 20 N183GA, while practicing ILS approaches in IMC with low clouds and rime ice, for causing the airplane to crash.
In one of its longest investigations into a general aviation accident, the NTSB released its final report last month on the Oct. 10, 2000, crash of a Canadian-registered Bombardier Challenger 604 during a manufacturer’s test flight at Wichita Mid-Continent Airport. The two pilots and flight engineer died as a result of injuries sustained from the accident.
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.”
Comments are due March 5 on an FAA proposal to require a low-airspeed awareness system on Cessna 208 and 208B Caravans. The installation will cancel the prohibition against operating the turboprop single in moderate or worse icing conditions.
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.
