Narrative:

Faced with a passenger experiencing severe chest pains, we requested expedited handling into O'hare at our normal descent point. Cleared direct, we started a steep descent. In all the confusion of flight attendants, paramedic arrangements, being 'hot' on the approach and accomplishing checklists, the first officer does not remember changing over to tower and receiving landing clearance prior to T/D. The tower made no mention at all. Crew discovered the problem upon landing when first officer noticed radio frequency had not been switched to tower. This occurrence happened after an all-night flight, and I am sure that this fatigue played a part in the error. Fortunately, the tower had expected and apparently cleared the runway for our landing. There is a possibility that the call was made and the frequency switch de-selected. Memories are foggy, which is also a function of the all-night flying.

Original NASA ASRS Text

Title: MLG FORGETS TO CHANGE TO TWR AND LANDS WITHOUT CLRNC.

Narrative: FACED WITH A PAX EXPERIENCING SEVERE CHEST PAINS, WE REQUESTED EXPEDITED HANDLING INTO O'HARE AT OUR NORMAL DSCNT POINT. CLRED DIRECT, WE STARTED A STEEP DSCNT. IN ALL THE CONFUSION OF FLT ATTENDANTS, PARAMEDIC ARRANGEMENTS, BEING 'HOT' ON THE APCH AND ACCOMPLISHING CHKLISTS, THE F/O DOES NOT REMEMBER CHANGING OVER TO TWR AND RECEIVING LNDG CLRNC PRIOR TO T/D. THE TWR MADE NO MENTION AT ALL. CREW DISCOVERED THE PROB UPON LNDG WHEN F/O NOTICED RADIO FREQ HAD NOT BEEN SWITCHED TO TWR. THIS OCCURRENCE HAPPENED AFTER AN ALL-NIGHT FLT, AND I AM SURE THAT THIS FATIGUE PLAYED A PART IN THE ERROR. FORTUNATELY, THE TWR HAD EXPECTED AND APPARENTLY CLRED THE RWY FOR OUR LNDG. THERE IS A POSSIBILITY THAT THE CALL WAS MADE AND THE FREQ SWITCH DE-SELECTED. MEMORIES ARE FOGGY, WHICH IS ALSO A FUNCTION OF THE ALL-NIGHT FLYING.
