What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
N178GC was in cruise flight on an air tour of the Grand Canyon when the flight crew reported hearing a loud squealing noise coming from the left engine, followed by a loud "bang" and loss of the left engine power. The flight crew secured the left engine following the emergency procedures checklist and made an uneventful landing at the Grand Canyon West Airport (IG4). During a post flight inspection, the flight crew noted the lower inboard section of the left engine cowling had several holes created by debris created when the engine suffered an uncontained engine failure. There was no damage noted to the aircraft fuselage or aircraft primary structure
