Washington, DC --The National Transportation Safety Board today issued two urgent recommendations to the Federal Aviation Administration to address a safety issue concerning a failure that resulted in uncontrollable engine thrust in an Eclipse 500 airplane and the lack of emergency procedures developed for that failure.
The Safety Board recommended that the FAA should require immediate inspection of all Eclipse 500 airplane throttle quadrants to ensure that pushing the throttle levers against the maximum power stops will not result in an engine control failure, and that the FAA should further require that all units that fail inspection be replaced and replacement parts be similarly inspected.
On June 5, 2008, an Eclipse 500 airplane, N612KB, on approach to Chicago Midway Airport, experienced a failure that resulted in uncontrollable maximum power thrust from two Pratt and Whitney
Canada PW610F turbofan engines. After referencing the emergency procedures of the airplane’s quick reference handbook, the pilots shut down one of the engines.
However, following the shutdown of the engine, the other engine rolled back to idle power and continued to be unresponsive to the throttle. The pilots declared an emergency, were cleared to land on any runway and were able to land the plane without injury to the two pilots or two passengers.
