WHILE ENGAGED IN CRUISE ON A SCHEDULED TRANSCONTINENTAL FLIGHT FROM NEW YORK TO LOS ANGELES, SEVERAL STAGE 1 HIGH PRESSURE TURBINE ROTOR BLADES WITHIN THE #1 ENGINE SEPARATED WITHOUT WARNING FROM THEIR PLATFORMS. THE INITIAL SEPARATION WAS FOUND TO HAVE ORIGINATED AT A BLADE FORWARD COOLING HOLE AND WAS DETERMINED TO BE FATIGUE INDUCED. THE FATIGUE WAS MOST LIKELY BROUGHT ON BY A DEGRADATION OF THE COOLING AIRFLOW PATTERN WITHIN THE BLADE INDUCED BY AN AIRFLOW LEAK NOT ASSOCIATED WITH THE BLADE COOLING HOLES. THE BLADE SEPARATIONS RESULTED IN DISINTEGRATION OF THE HIGH PRESSURE TURBINE ASSEMBLY AND SUBSEQUENT ENGINE FAILURE.
