When it issued Eclipse 500 Airworthiness Directive 2008-24-07, which becomes effective today, the FAA asked for comments from operators. The AD limits the Eclipse 500 to a maximum pressure altitude of 37,000 feet due to “several incidents of engine surge” of the jet’s Pratt & Whitney Canada PW610F-A engines. The surge is due to carbon buildup on the static vane during high bleed flow conditions.
