Incident
On June 28, 2015, at 2320 eastern daylight time, a passenger fell when exiting the aft lavatory on Delta Airlines flight 2219, an Airbus A320 (registration N335NW), while the airplane was in descent to Boston Logan International Airport (BOS), Boston, Massachusetts. According to flight crew statements, the seatbelt sign was illuminated and a public address announcement had been made to remain seated prior to beginning the initial descent.
Descent and Autopilot Disconnect
About 5 minutes into the descent, the autopilot was disconnected to manage the descent profile, which resulted in a "bump" in the flight path. According to flight attendant statements, around this time, a passenger fell while exiting the rear lavatory, injuring her ankle.
Medical Response
Doctors who were onboard assisted in applying ice and providing pain medication. The flight crew declared an emergency with air traffic control. Emergency medical personnel met the airplane at the gate and transported the passenger to the hospital, where she was diagnosed with a fractured right ankle and lower right leg.
Passenger's Account
Subsequent communication from the passenger to Delta stated that she had slipped on an area of water on the floor near the lavatory door. The aircraft was operating under 14 CFR Part 121 as a scheduled flight from Orlando International Airport, Florida.
