LAS VEGAS, N.M. (KRQE) – The National Transportation Safety Board has released the final report detailing what caused the Bernalillo County Sheriff’s Office “Metro 2” helicopter to crash. The crash happened on July 16, 2022, and killed all four crew members, in Chapelle near Las Vegas, New Mexico.
According to NTSB, the probable cause of the accident was “due to poor maintenance.” The report states that the starter-generator input gear failed due to fatigue. The failure then led to the “starter-generator driveshaft shearing, accessory gearbox seizure, and a total loss of engine power.”

According to the report, about 17 flight hours before the accident, an engine chip event occurred and a small piece of ferrous metal was found on the magnetic chip plug. The oil system was then drained and flushed and the filter elements were removed, cleaned, and reinstalled. The chip and oil sample were shipped to a lab for analysis. However, the results of the lab analysis were not used by BCSO to troubleshoot the reason for the chip event. According to NTSB, “had the operator conducted an analysis, they could have potentially identified the deterioarting component and impending failure.”
The report also states that unsuccessful autorotation by the setting sun and high-density altitude contributed to the accident.
The Metro 2 helicopter was assisting fire crews with the East Mesa Fire. The crash killed BCSO Undersheriff Larry Koren, Lt. Fred Beers, Deputy Michael Levison, and Bernalillo County Fire Department Rescue Specialist Matthew King.
