ASX Accident Report
On the morning of Saturday, May 17, 2025, a Beechcraft 95-B55 Baron, registration N4321Z, departed from Rocky Mountain Metropolitan Airport (KBJC) in Broomfield, Colorado. The aircraft, owned and operated by CEDOCS, was a privately operated 1972 twin-engine model with two occupants on board. Approximately three minutes after takeoff from runway 30R, at around 10:03 a.m. local time, the aircraft climbed to an estimated altitude of 300 feet above ground level before initiating a right-hand descending turn. This maneuver occurred shortly after the pilot made a radio transmission indicating the need to return to the airport due to an onboard issue.
Air traffic control recordings captured the pilot’s transmission stating, “We're going to have to go back and re-land. We've got the door popped open... we can hardly hear you, sir.” The tower immediately cleared the aircraft to return and land on any available runway. No further communication was received from the aircraft after that point. Witnesses and radar tracking confirmed that the aircraft lost altitude quickly and impacted a field east of Brainard Road, just north of U.S. Route 36, in the vicinity of the Carolyn Holmberg Preserve.
Emergency services were dispatched immediately following the radio call and subsequent disappearance of the aircraft from radar. Upon arrival, responders found the aircraft on fire and were able to extinguish the blaze rapidly. The crash resulted in the complete destruction of the airframe and the deaths of both individuals on board. The National Transportation Safety Board (NTSB) and the Federal Aviation Administration (FAA) began an investigation into the cause of the crash, and the site was secured for further examination. Data from ADS-B tracking and communications were preserved for analysis.
Preliminary findings suggest that the emergency originated from a mechanical issue involving the cabin door, which may have compromised cockpit communication or flight stability during a critical phase of flight. However, no conclusions regarding the root cause of the crash have been released pending full investigation results. The flight did not have a specified destination, and the nature of the flight was personal or private in purpose. Investigative teams continue to review physical wreckage, maintenance history, and pilot records to determine the underlying factors leading to the loss of control shortly after takeoff.
