Flight 261 was headed from Puerto Vallarta, Mexico, to Seattle when it crashed on Jan. 31, 2001, some eight miles off the Ventura County coast near Anacapa Island.
The Ventura County Star says families gather each year at the Port Hueneme Beach Park memorial to celebrate the dead.
On Thursday, they prayed for the victims and read the name of each person who died. With each name, a bell rang and a rose was placed on the names ringing the 10-foot sundial monument.
Failure of a jackscrew in the plane's tail caused the crash.
