What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) After departing the Nome Airport, the PIC retracted the landing gear and heard a loud bang. Twenty seconds later he heard another. The right engine ingested a nylon cargo strap which was wrapped around the fixed intake vanes. This produced a disruption in the airflow enough to cause a compression stall. These types of nylon straps usually have a metal piece that holds them together. It is probable this piece of metal went through the engine due to small nicks that were on the forward compressor blades. A mechanic with Alaska airlines "blended the blades" on the C-1 (first set of compressor blades) then borescoped the rest of the engine. The aircraft was flown back to anchorage the next morning. The engine was removed three days after the incident due to an unfavorable "a" check pertaining to the damage from this incident.

THE RIGHT ENGINE INGESTED A NYLON CARGO STRAP WHICH WAS WRAPPED AROUND THE FIXED INTAKE VANES. THIS PRODUCED A DISRUPTION IN THE AIRFLOW ENOUGH TO CAUSE A COMPRESSION STALL. THESE TYPES OF NYLON STRAPS USUALLY HAVE A METAL PIECE THAT HOLDS THEM TOGETHER. IT IS PROBABLE THIS PIECE OF METAL WENT THROUGH THE ENGINE DUE TO SMALL NICKS THAT WERE ON THE FORWARD COMPRESSOR BLADES. A MECHANIC WITH ALASKA AIRLINES "BLENDED THE BLADES" ON THE C-1 (FIRST SET OF COMPRESSOR BLADES) THEN BORESCOPED THE REST OF THE ENGINE. THE AIRCRAFT WAS FLOWN BACK TO ANCHORAGE THE NEXT MORNING.
