Briefing

The Asiana Airlines flight crew mismanaged the descent of a 777 into San Francisco International Airport last July, the NTSB said in its probable-cause hearing in June. The pilots made several mistakes and by the time they decided to go around it was too late. The airplane hit the seawall, causing a fiery crash that killed three passengers and seriously injured 49. The board also found the complexities of the auto-throttle and autopilot flight director systems contributed to the crash, and should have been more clearly described both in Boeings documentation and in Asiana pilot training. Crew fatigue also was a factor. The board also said emergency responders on the scene, who ran over one of the crash victims with a fire truck, should have been better trained and equipped. The board followed up with 27 safety recommendations to the airline, Boeing, the aircraft firefighting group, and the city and county of San Francisco.

lectric-powered airplanes may still be far from mainstream, but interest in this technology continues to grow. In late April, Airbus engineers successfully flew the E-Fan, a tandem two-seater with a pair of electric-powered ducted fans on the tail. The batteries, carried in the wings, provide 30 minutes of flight.

Cirrus has been flying a Vision jet since 2008, but the first copy of the final production version flew for the first time on March 24. The jet is one of three conforming flight-test aircraft that will complete the flight-test regime, with deliveries expected to start late next year. Cirrus chief test pilot Mike Stevens flew the jet for an hour after takeoff from Duluth (Minn.) International Airport, and said it handled and performed very well and all systems functioned properly, just what you want in a first flight. The SF50 is a seven-seat, pressurized, single-engine jet, with a price of $1.96 million. Cirrus CEO Dale Klapmeier said the company has 500 reservations for the aircraft.
