What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) Uala flight yvr-ord diverted to seattle-tacoma airport because of a flight control vibration. The aircraft landed without incident.

A 8"-18" piece of the trailing edge wedge had broken away. The wing panels had a 8" span wise crack and a 6" hole which had the honeycomb core missing. The movement of the slat had made heavy rub marks on the wing skin. The top of the slat showed evidence of disbond of the aluminum skin from the honeycomb core. United airlines maintenance records indicate #6 slat was installed on 07-2003. Unable to determine if the installed slat was new or had been repaired. Injury summary not known by ASI.
