Narrative:
Perform special item card #X on #2 engine, which required opening #2 engine fan cowling. Upon completion of the job I secured fan cowling closed. I was informed by management that the fan cowling had blown off upon aircraft landing in ZZZ1. Best of my knowledge I secured the fan cowling closed. Callback conversation with reporter revealed the following information: the reporter stated the right engine fan cowling was opened to accomplish a special item job card and after completion of the job was closed and the latches secured. The reporter said the cowling was secure for takeoff, climb and cruise and only on landing did the cowling come off. The reporter stated the fan cowling does not have a latch in the center of the fan cowl. The reporter said no unlocked latches were hanging down after closure.
