From the FAA’s Accident/Incident Data System (AIDS), through its Aviation Safety Information Portal, as reported. The NTSB investigates accidents separately, and its record of an accident is the fuller one. The aircraft is matched to the registry by N-number and event date, checked against the reported make and model; the registry’s history has gaps, so older matches can be wrong. Compare the reported make and model.

What happened

The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.

On may 17, 2025, a Beechcraft, model 95-55 (T42A) departed kbjc Rocky Mountain Metropolitan Airport. Shortly after takeoff, the pilot radioed that they had a "door pop" and requested to return to land.

LC1 controller instructed a/c to enter right traffic to runway 30R. Pilot did not respond. LC1 controller observed the a/c flying at a low altitude and asked if they could climb. Pilot again stated the need to return due to the open door and stated they were having difficulty hearing the tower.

The a/c started a continuous slow descent with the landing gear extended entering a left bank that increased in roll rate until the a/c was in a left wing down and nose low dive. The aircraft crashed in a field approx. 1.5 miles north of runway 30R impacting the terrain in an estimated 90 degree left bank and nose down attitude. There was a post-accident fire and two fatalities.
