NTSB Releases Preliminary Report on Arizona Helicopter Crash
NTSB reports on the February 4 crash of an Arizona DPS Bell 407 helicopter during an active shooter incident in Flagstaff, resulting in two fatalities.
This article is based on an official press release from the National Transportation Safety Board (NTSB).
The National Transportation Safety Board (NTSB) has released its preliminary report regarding the fatal February 4 crash of an Arizona Department of Public Safety (AZDPS) helicopters in Flagstaff, Arizona. The incident claimed the lives of two crew members who were providing tactical air support during an active shooter situation.
According to the official NTSB release, the ongoing investigation is examining the circumstances that led the Bell 407 helicopter to crash in a residential area. The preliminary findings offer initial data points, though a final determination of the probable cause is not expected for several months.
NTSB issues its preliminary report for the ongoing investigation of the Feb. 4 crash of a Bell 407 helicopter in Flagstaff, Arizona.
Details of the Incident
On the evening of February 4, 2026, the AZDPS helicopter was dispatched to assist the Flagstaff Police Department with an active shooter incident. The crew consisted of Pilot Robert Bruce Skankey and State Trooper/Paramedic Hunter R. Bennett. Both sustained fatal injuries when the aircraft went down at approximately 10:15 p.m. local time, according to timelines cited by Beaumont Enterprise.
The aircraft was operating in clear weather conditions with light winds. According to reporting by Red Rock News, the helicopter was a 2004 model with tail number N56AZ. The same outlet noted that Automatic Dependent Surveillance–Broadcast (ADS-B) data indicated the aircraft entered a rapid climb late in the flight, with groundspeeds dropping to as low as 4 knots, before entering an out-of-control spin. Witnesses on the ground reported hearing a loud pop prior to the descent.
The Investigation and Aftermath
The NTSB, assisted by the Federal Aviation Administration (FAA), is leading the federal investigation into the crash. Investigators are analyzing the aircraft’s maintenance records, flight data, and environmental factors. Beaumont Enterprise reported that the aircraft crashed approximately 50 feet from a BNSF Railway line, resulting in a post-crash fire.
While the NTSB preliminary report outlines the factual circumstances of the flight, it does not establish a causal chain. The suspect involved in the ground shooting, identified in media reports as Terrell Story, was taken into custody. He has been indicted on multiple charges, including two counts of first-degree felony murder related to the deaths of the flight crew during the commission of a felony.
AirPro News analysis
The deployment of public-safety aviation units in urban environments at night introduces complex mission demands. Tactical air support requires sustained low-altitude maneuvering, frequent radio communications, and heightened situational awareness relative to terrain and obstacles.
We anticipate the NTSB’s final report will likely focus heavily on the mechanical integrity of the helicopter’s tail rotor and transmission systems, given witness reports of a pop and video evidence of an out-of-control spin. Additionally, investigators will evaluate whether the ground threat directly impacted the aircraft, though current public releases have not confirmed if the helicopter sustained gunfire.
