From the Wikipedia article
PenAir Flight 3296 was a domestic scheduled flight from Ted Stevens Anchorage International Airport in Anchorage, Alaska, to Unalaska Airport on Amaknak Island in the Aleutian Chain of Alaska. On October 17, 2019, the Saab 2000 operating the flight overran the runway after landing at Unalaska Airport. Of the 42 passengers and crew on board, one passenger (identified as David Allan Oltman) was fatally injured when a propeller blade penetrated the fuselage, one was seriously injured and ten suffered minor injuries. The aircraft was substantially damaged during the accident and written off.
Accident
On the day of the accident, the aircraft departed from Anchorage at 15:15 AST and was due to land at Unalaska two hours and 15 minutes later. While descending toward Unalaska, the crew received clearance for an RNAV approach to Runway 13, a 1372 m runway. As the aircraft approached the airport, the wind changed from 210 degrees at 8 kn to 180 degrees at 7 kn, but was reported as 270 degrees at 10 kn. The aircraft became unstable and a go-around was executed. The flight returned for a visual approach onto Runway 13. The wind speed increased and the controller reported that winds were 300 degrees at 24 kn.
According to the investigation report, the pilots believed there was a crosswind during the landing approach, based on seeing waves by the nearby shore and a windsock near the runway, but in contradiction to the weather control report and onboard witness statements.
The crew decided to continue with the landing and touched down at 17:40. The aircraft landed 305 m down the runway with reverse thrust and wheel-braking inputs by the captain. When the aircraft reached 80 kn, maximum braking was applied. As an overrun was imminent, the pilots steered the aircraft right to avoid going into the water past the runway end. Attempts to stop on the paved runway surface failed, and the aircraft crossed a section of grass and then broke through a chain perimeter fence and crossed a ditch. The aircraft struck a large rock, crossed a public roadway and finally came to a stop on the shore of Iliuliuk Bay. The port wing or propeller struck a 4-5 ft signal post, the port propeller struck a 6 to 8 ft yellow diamond shaped road sign, and again struck rock riprap as the plane came to a halt. This caused the port-side (left) propeller to shatter, sending debris and large pieces of the propeller blade into the fuselage. One of the blades was found inside the cabin. Two passengers were critically injured and another 10 had to receive medical care. David Allan Oltman died a day later.
Investigation and cause
Investigation
On the day of the accident, the National Transportation Safety Board (NTSB) launched an investigation. Two years later, on November 2, 2021, the final report was released, which stated that the accident had been caused by "the landing gear manufacturer's incorrect wiring of the wheel speed transducer harnesses on the left main landing gear during overhaul." Saab's design of wire harnesses, the Federal Aviation Administration (FAA) authorizing Unalaska Airport to operate the Saab 2000 without taking the runway safety area into consideration first, and the flight crew's decision to land in a tailwind that exceeded Saab's limits (which the NTSB labeled as inappropriate) were also factors in the accident.

NTSB narrative
On October 17, 2019, about 1740 Alaska daylight time, PenAir flight 3296, a Saab 2000, N686PA, overran the runway while landing at the Thomas Madsen Airport (PADU), Unalaska, Alaska. The airplane passed through the airport perimeter fence, crossed a road, and came to rest on shoreline rocks. Of the 42 passengers and crewmembers on board, 1 passenger was fatally injured, and several other passengers sustained serious or minor injuries. The airplane received substantial damage. The regularly scheduled domestic passenger flight was operating under the provisions of 14 Code of Federal Regulations Part 121 from Ted Stevens International Airport (KANC), Anchorage, Alaska, to PADU.
Probable cause
The landing gear manufacturer’s incorrect wiring of the wheel speed transducer harnesses on the left main landing gear during overhaul. The incorrect wiring caused the antiskid system not to function as intended, resulting in the failure of the left outboard tire and a significant loss of the airplane’s braking ability, which led to the runway overrun. Contributing to the accident were (1) Saab’s design of the wheel speed transducer wire harnesses, which did not consider and protect against human error during maintenance; (2) the Federal Aviation Administration’s lack of consideration of the runway safety area dimensions at Unalaska Airport during the authorization process that allowed the Saab 2000 to operate at the airport; and (3) the flight crewmembers’ inappropriate decision, due to their plan continuation bias, to land on a runway with a reported tailwind that exceeded the airplane manufacturer’s limit. The safety margin was further reduced because of PenAir’s failure to correctly apply its company-designated pilot-in-command airport qualification policy, which allowed the accident captain to operate at one of the most challenging airports in PenAir’s route system with limited experience at the airport and in the Saab 2000 airplane.
