Narrative:

During a busy ILS runway 24R approach to lax, after approach had instructed us to 'switch to tower frequency once established on the approach,' failed to switch to tower frequency, and thus landed without tower clearance. Discovered error upon clearing the runway and holding short of the inboard, when attempted tower contact and reached approach control. Switched to tower immediately and checked in. Instructed to hold short. Fundamental step was missed during busy approach. Corrective action: carry out good habit patterns that have already been developed. Normally, as the PF, I always do a final check (which includes a landing clearance check) once all checklists are complete.

Original NASA ASRS Text

Title: AN MD83 LANDS ON RWY 24R AT LAX WITHOUT BENEFIT OF LNDG CLRNC.

Narrative: DURING A BUSY ILS RWY 24R APCH TO LAX, AFTER APCH HAD INSTRUCTED US TO 'SWITCH TO TWR FREQ ONCE ESTABLISHED ON THE APCH,' FAILED TO SWITCH TO TWR FREQ, AND THUS LANDED WITHOUT TWR CLRNC. DISCOVERED ERROR UPON CLRING THE RWY AND HOLDING SHORT OF THE INBOARD, WHEN ATTEMPTED TWR CONTACT AND REACHED APCH CTL. SWITCHED TO TWR IMMEDIATELY AND CHKED IN. INSTRUCTED TO HOLD SHORT. FUNDAMENTAL STEP WAS MISSED DURING BUSY APCH. CORRECTIVE ACTION: CARRY OUT GOOD HABIT PATTERNS THAT HAVE ALREADY BEEN DEVELOPED. NORMALLY, AS THE PF, I ALWAYS DO A FINAL CHK (WHICH INCLUDES A LNDG CLRNC CHK) ONCE ALL CHKLISTS ARE COMPLETE.
