A 2026 helicopter crash in Flagstaff killing two DPS officers was caused by rotor failure, not gunfire, NTSB says.

A preliminary National Transportation Safety Board report attributes the February 4, 2026, helicopter crash in Flagstaff, Arizona, which killed two Arizona Department of Public Safety officers, to a mechanical failure in the main rotor system, not gunfire. Despite gunfire during the incident, no ballistic damage was found, and the aircraft experienced sudden rotor separation, leading to an uncontrolled descent. The crash occurred during a pursuit of suspect Terrell Storey, 50, who faces multiple felony charges, including first-degree murder. The final NTSB report is expected in a year or more.
