Narrative:

Arrived in boi area at time when air force 2 was departing. Airport was closed. Held VMC northeast of airport for approximately 5 mins. Cleared for visual approach. Approach did not hand me off to tower. I forgot to call tower. Landed west/O landing clearance. Talked with tower chief on phone. No traffic conflicts. I reported the incident to my management. How the problem arose: the captain, first officer and approach controller all forgot at the same time about switching to tower frequency. How it was discovered: when the first officer requested permission to cross the parallel runway. Contributing factors: nonroutine operations, ie, airport closed. I was conducting initial operating experience with the first officer. To this day, I remember hearing 'cleared to land,' when probably what I heard was 'cleared for the visual.' this is probably due to me hearing what I wanted to hear. From the time that I was cleared for the visual until the time I actually landed was approximately 3 mins. I'm a bit surprised that I was never contacted on approach frequency prior to landing concerning switching to tower frequency since the tower chief stated that the tower controllers tried twice to call me while I was on final--first attempt was while I was on a 5 mi final.

Original NASA ASRS Text

Title: ACR MLG LANDED WITHOUT TWR CLRNC.

Narrative: ARRIVED IN BOI AREA AT TIME WHEN AIR FORCE 2 WAS DEPARTING. ARPT WAS CLOSED. HELD VMC NE OF ARPT FOR APPROX 5 MINS. CLRED FOR VISUAL APCH. APCH DID NOT HAND ME OFF TO TWR. I FORGOT TO CALL TWR. LANDED W/O LNDG CLRNC. TALKED WITH TWR CHIEF ON PHONE. NO TFC CONFLICTS. I RPTED THE INCIDENT TO MY MGMNT. HOW THE PROB AROSE: THE CAPT, F/O AND APCH CTLR ALL FORGOT AT THE SAME TIME ABOUT SWITCHING TO TWR FREQ. HOW IT WAS DISCOVERED: WHEN THE F/O REQUESTED PERMISSION TO CROSS THE PARALLEL RWY. CONTRIBUTING FACTORS: NONROUTINE OPS, IE, ARPT CLOSED. I WAS CONDUCTING INITIAL OPERATING EXPERIENCE WITH THE F/O. TO THIS DAY, I REMEMBER HEARING 'CLRED TO LAND,' WHEN PROBABLY WHAT I HEARD WAS 'CLRED FOR THE VISUAL.' THIS IS PROBABLY DUE TO ME HEARING WHAT I WANTED TO HEAR. FROM THE TIME THAT I WAS CLRED FOR THE VISUAL UNTIL THE TIME I ACTUALLY LANDED WAS APPROX 3 MINS. I'M A BIT SURPRISED THAT I WAS NEVER CONTACTED ON APCH FREQ PRIOR TO LNDG CONCERNING SWITCHING TO TWR FREQ SINCE THE TWR CHIEF STATED THAT THE TWR CTLRS TRIED TWICE TO CALL ME WHILE I WAS ON FINAL--FIRST ATTEMPT WAS WHILE I WAS ON A 5 MI FINAL.
