What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
privacy data omitted Departed myat original destination kgsp diverted to kmlb. privacy data omitted Leveled at FL340 near MLB108098 being work by zma R2 frequency 119.82 squawked emergency and executed rapid descent from FL340 to 120, then reestablished communication with R2 and then advised thought he lost passenger door. The aircraft then landed without incident. Pilot states that the door was lost somewhere over the ocean. Inspection of the aircraft revealed a door hinge was largely intact but with separated/missing hardware where it attached to the door. The door hinge was still attached to the fuselage side. The airstair door handle anchor on the fuselage side failed in sheer, door damper support was bent out of shape with upper bolt head sheared, from the door departing the aircraft. The door plate strikers (X6) on the fuselage remained undamaged. It is determined that the failure is either within the door mechanism or the door was not latched properly. When asked, the pilot was sure he engaged the door lock properly before flight. Because the main door is missing, a final determination cannot be made. No further action can be taken at this time.
