NTSB narrative
The on-demand passenger flight was cruising at flight level 190 when the passenger/crew door separated from the airframe. Visual meteorological conditions with no reported turbulence prevailed at the time of the incident. The door was recovered in the locked position. Examination of the door revealed a fatigue fracture of the upper aft latch bolt. There were no indications of damage to the door frame and latch plates.
Probable cause
The fatigue failure of the passenger/crew door latch pin during cruise flight.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
