A study conducted by NBAA has found that 15 percent of flights in business jets begin without a complete flight-control check, the association reported last week. The NTSB suggested a need for the study after its investigation of a fatal 2014 accident involving a Gulfstream G-IV at Hanscom Field, in Bedford, Mass. The safety board found the crew had not performed a flight-control check before takeoff, and as a result, they had no way of knowing the aircraft’s gust lock was engaged. The jet ran off the runway and caught fire, killing all seven on board.
