A Third Beechjet Flameout Under Investigation

On June 14, Beechjet 400A N440DS lost all power from both Pratt & Whitney Canada JT15D-5 engines while the airplane was in cruise flight at FL380 near Norfolk, Va. Unsure if they could remain clear of clouds, the pilots decided to turn on the engine anti-ice. They told the NTSB that they turned on the engines' igniters and then retarded the power from 101.5 percent to 89.5 percent N1, but before they could reach up to turn on the anti-ice, both engines flamed out simultaneously. The left engine restarted on its own at about FL300 and the right engine restarted on its own at about FL240. Testing of the fuel that was drained from the airplane confirmed that icing inhibitor was present and in the correct concentration and that the fuel was jet-A. The NTSB is also investigating two previous Beechjet dual engine flameouts–on July 12, 2004, over the Gulf of Mexico and another on Nov. 28, 2005, near Jacksonville, Fla. Both of these aircraft were being operated by Flight Options. Investigations of all three incidents are ongoing.
