Abstract

Verbatim from NTSB Aircraft Accident Reports. Not paraphrased, not summarized.

Southwest 1380 (B737-700) Philadelphia, April 17, 2018 — uncontained engine failure, passenger fatality. Examines the uncontained failure of a CFM56-7B fan blade due to high-cycle fatigue that breached the engine inlet cowl, broke a passenger window, and killed one occupant. Drove revisions to the FAA Airworthiness Directive program for CFM56 fan blade ultrasonic inspections (AD 2018-09-10) and prompted EASA + FAA coordination on engine cowl and window certification.
