The NTSB issued six recommendations stemming from the Sept. 19, 2008 overrun crash of a Learjet 60. In its recommendations to the FAA, the Safety Board wrote that it wants Bombardier to change the design of the Learjet 60 thrust-lever system so that the reverse-lever positions in the cockpit match the positions of the thrust-reverser mechanisms at the engines when the thrust reversers stow. Additionally, the NTSB is asking for improved aural or visual cues that would allow Learjet 60 pilots to recognize an inadvertent thrust-reverser stowage. The Board also recommends that all Learjet 60 pilots receive training on recognizing an inadvertent thrust-reverser stowage. Another recommendation calls for an evaluation of the Hawker 1000 thrust-reverser controls for similar potential failure modes.
