The DC-9 departed and climbed to flight level 290. About 1 hour and 35 minutes after departure, the airplane was cleared by ATC to 17,000 feet msl. Upon receiving the clearance, the captain initiated approximately a 3,500 foot per minute descent, and slowed to 280 knots. While in the descent and passing flight level 235, the airplane encountered the wake turbulence of a cargo Boeing 747, which was 12 nautical miles ahead and also descending to 17,000 feet msl. The captain of the DC-9 pitched the airplane's nose up to exit the wake turbulence, and requested additional separation between the two airplanes from ATC. During the wake turbulence encounter, a flight attendant in the galley slipped, and seriously injured her right ankle.
Probable Cause: The wake turbulence from the proceeding Boeing 747.
