Press report (Guardian) states that after the previous very similar incident with a PW4077 engined UAL machine at Honolulu in 2018 examinations were mandated every 6500 cycles. The aircraft in that case was N773UA. The failed engine had approx 14000 cycles at the time of failure.
Previous checks had found an anomaly in the blade in question but had concluded it to be a paint issue.
