As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

THE PILOT IN COMMAND STATED THAT WHILE DESCENDING THROUGH 16,000 FT MSL, AND SLOWING FROM 190 KNOTS TO 160 KNOTS, THE AIRCRAFT ENCOUNTERED "SEVERE TURBULANCE."  AFTER LANDING AT MMH AND DOING A POSTFLIGHT INSPECTION, THE PILOT IN COMMAND STATED THAT HE DISCOVERED THAT BOTH WINGS SUSTAINED STRUCTURAL DAMAGE.
