What happened
During the flare phase of landing, the captain and first officer reported that the right propeller beta light illuminated. Following this illumination, the aircraft yawed to the right and descended with the right wing low, which subsequently contacted the ground. The aircraft remained on the ground, traveled off the runway, and came to a stop in the grass adjacent to the runway.
The investigation
Following the accident, the aircraft was removed from the site. The following day, under the supervision of the FAA, the right engine and propeller underwent operational testing. This inspection revealed no evidence of malfunction regarding the fuel flow, propeller blade angle rigging, or a worn flight idle gate.
