A software update to the Eclipse 500 jet will solve a problem that was the subject of a recent FAA emergency airworthiness directive, Eclipse Aviation said on Tuesday. Earlier this month, two pilots on approach to Midway Airport in Chicago experienced a throttle failure, resulting in maximum uncontrolled thrust from both Pratt & Whitney Canada PW601F turbofan engines. Eclipse says its solution will increase the range limit of the throttle quadrant assembly to prevent the fault condition from occurring. The fix requires approval from the FAA. Eclipse also has updated the Eclipse 500 flight manual and quick reference handbook to include procedures for handling a similar incident. In the Midway incident, the FAA said, the pilot applied full throttle with enough force against the forward stops to exceed the design throttle position signal maximum range. The associated fault mode held the engine thrust settings at the last known throttle position, which was maximum. The pilots were able to land safely after shutting down one engine and declaring an emergency.
