The cracked lugs resulted in the release of four 2nd stage turbine blades that penetrated the engine's cases and nacelle. The lugs cracked due to loss of material and resultant increase in stress load on the blade slot serrations due to excessve grit blasting when the hub was being overhauled  by Delta Air Lines. Contributing to the uncontained incident was the FAA's and Pratt & Whitney's failure to act in a timely manner when another PW2037 2nd stage turbine hub was found to have multiple cracks in the blade retaining lugs.","registration":"N666DN","state":"NV","summary":"Incident on August 6, 2008 at Las Vegas, NV: no injuries.","type":"INC"}],"num_engines":2,"other_names":"","plain_english":"N666DN is a Boeing 757-232, a fixed-wing airplane with more than one motor with turbofan engines, built in 1991.
