## Probable cause

A No. 2 (right) engine failure due to a spinner fairing separation and subsequent impact with the fan blades that resulted in a midspan fracture of one fan blade. The spinner fairing separated as a result of a fatigue crack that originated from the heat affected zone of a tack weld that secured a spacer to the aft side of the fairing. Contributing to the incident was inadequate spinner fairing inspection procedures that did not require removal of the spinner fairing to inspect the aft side for earlier detection of crack indications.
