Narrative:

The captain I was flying with was new to the medium large transport. He became absorbed in observing my use of the autoplt and non flying duties and failed to switch from approach control to the tower. I failed to notice that we never made the frequency change and landed without a landing clearance. I have since added a landing clearance check in my 500' callouts. Supplemental information from acn 117280: during my first line trip after line training, we were doing an instrument approach to san and I failed to switch to tower for landing clearance. No conflict occurred. My inexperience in the aircraft caused me to focus more than normal attention to the IFR approach.

Original NASA ASRS Text

Title: ACR ACFT LANDED WITHOUT CLRNC.

Narrative: THE CAPT I WAS FLYING WITH WAS NEW TO THE MLG. HE BECAME ABSORBED IN OBSERVING MY USE OF THE AUTOPLT AND NON FLYING DUTIES AND FAILED TO SWITCH FROM APCH CTL TO THE TWR. I FAILED TO NOTICE THAT WE NEVER MADE THE FREQ CHANGE AND LANDED WITHOUT A LNDG CLRNC. I HAVE SINCE ADDED A LNDG CLRNC CHECK IN MY 500' CALLOUTS. SUPPLEMENTAL INFORMATION FROM ACN 117280: DURING MY FIRST LINE TRIP AFTER LINE TRAINING, WE WERE DOING AN INSTRUMENT APCH TO SAN AND I FAILED TO SWITCH TO TWR FOR LNDG CLRNC. NO CONFLICT OCCURRED. MY INEXPERIENCE IN THE ACFT CAUSED ME TO FOCUS MORE THAN NORMAL ATTN TO THE IFR APCH.
