Probable cause
The 4th stage turbine blade separation that resulted in an uncontained release of low pressure turbine blade material was Delta Air Lines' repair process for the turbine blades' tip shrouds. It was not possible to identify the part of the repair process that led to the premature wear of the blade's tip shoud and subsequent separation.
