Incident Details
According to the director of aviation safety for the operator, after landing and while the aircraft was parked at the ramp, the pilot in command left the flight deck to open the main cabin door. Upon reaching the door, the pilot found the lead passenger standing directly in front of it, waiting to exit. The pilot was able to open the door from that position but did not have room to exit the aircraft ahead of the passenger.
As the passenger began descending the airplane's air stairs, her foot slipped. She landed on her knees and caught her balance by grabbing onto the handrails. A subsequent medical examination revealed that the passenger had broken her ankle.
Mechanical Status
The director of aviation safety reported that there were no pre-accident mechanical malfunctions or failures with the airplane that would have precluded normal operation.
