Improper operation of the galley elevator on a United Airlines Boeing 747-400 caused serious injury to a flight attendant on a Singapore-Tokyo Narita flight on 9 June, and caused the captain to divert the aircraft to Hong Kong.
An initial US Federal Aviation Administration report of the incident says that the flight attendant was placing a galley cart on to the elevator in the main deck galley to move the cart to the upper deck when the elevator began to move upwards, causing the cart to roll off the elevator, strike the flight attendant and pin her against the galley wall.
The FAA quotes a United Airlines report of the accident as saying that inspection of the elevator at Hong Kong revealed that a piece of paper had been inserted into the interlock safety switch, disabling it and allowing the elevator to be operated without closing the galley elevator door.
