(LOUISVILLE, Ky.) — Newly released photos included in a National Transportation Safety Board preliminary report on the deadly UPS plane crash in Louisville show the moment the aircraft’s left engine came off during takeoff and ignited.

Federal investigators are focusing on metal fatigue cracks around the engine of the UPS plane that crashed on Nov. 5, killing 14 people, according to a new report by the NTSB.

In a preliminary report released Thursday, the engine is seen flying off the McDonnell Douglas MD-11 freighter plane’s wing, going up into the air, before a burst of fire engulfs the plane.

The plane was departing Louisville Muhammad Ali International Airport, and headed to Daniel K. Inouye International Airport in Honolulu, when the crash occurred.
