Aircraft mechanic here. And yes i am a Little bit disturbed that a leak like this happened. Shouldn’t be because there are names of flight crew and mechanics. Apart from that there are more than one copy of the report. As you can read on the bottom of said report. The pink we got is meant to stay with the technical Departement
I'm also disturbed that this document is in the public domain, but having lived and worked in Jakarta, I am not in the least bit surprised.
