Travis Barker Fixing Tats Damaged in Plane Crash

Barker was outside Zulu Tattoo in L.A. last week ... when he told us, "Where I got burned ... I started finishing some of the tattoos that got burned off."

As TMZ reported, Barker and DJ AM were the only two survivors of the 2008 plane crash -- when a private jet they were on blew a tire while taking off, lost control and crashed into an embankment. The plane burst into flames ... and four people were killed.

Months after the crash, Barker played a show in Vegas without a shirt -- revealing serious burn scars to his entire back.
