Narrative:

Instructed by approach to contact tower at the outer compass locator. Traffic was on parallel approach to 26L, we were on visual approach to 26R. I was anticipating a TCASII alert (RA) because of the closeness of the traffic. The preoccupation with the TCASII and traffic caused me to forget to switch to tower frequency. We landed without ever calling tower and receiving a landing clearance.

Original NASA ASRS Text

Title: LGT TOLD TO CONTACT TWR AT OM, FAILS TO DO SO. LWOC.

Narrative: INSTRUCTED BY APCH TO CONTACT TWR AT THE OUTER COMPASS LOCATOR. TFC WAS ON PARALLEL APCH TO 26L, WE WERE ON VISUAL APCH TO 26R. I WAS ANTICIPATING A TCASII ALERT (RA) BECAUSE OF THE CLOSENESS OF THE TFC. THE PREOCCUPATION WITH THE TCASII AND TFC CAUSED ME TO FORGET TO SWITCH TO TWR FREQ. WE LANDED WITHOUT EVER CALLING TWR AND RECEIVING A LNDG CLRNC.
