Narrative:
We were cleared for the ILS and the aircraft confign was flaps 15 degrees, gear up. The airspeed was 170 KTS and our location was outside the LOM, on GS and on course. I was the PF. As we neared the LOM we had a visual on the runway. I disconnected the autoplt and autothrottles and was flying manually. We were about 3 mi behind another aircraft and #2 for landing. The right throttle was 'stiffer' than normal, making symmetrical thrust applications troublesome. As we approached the LOM, we contacted tower and were given landing clearance. My attention on the aircraft ahead, instrument xchk and the throttle difficulty completely absorbed my focus. So much so, that I missed the 1000 ft AGL call by the first officer or if I heard if, my brain didn't register the information. It wasn't until the GPWS vocal annunciation of 'too low, gear' sounded that I realized the aircraft wasn't configured for landing. The gear was extended, and then flaps were extended to landing position in normal sequence. The landing was made without further incidence. Besides the embarrassment of making a 'student pilot' error, I felt the dread of realization of 'what might have been,' had the GPWS not functioned! Perhaps the early wakeup (XA00 am), the end of a 4-DAY trip, the mid-afternoon slump or just plain 'get-home-itis' or all of these together in addition to my own complacency, added up to a very dumb mistake with possibly very serious consequences.
Original NASA ASRS Text
Title: B767-300 CREW FORGOT TO LOWER THE LNDG GEAR OR EXTEND LNDG FLAPS UNTIL THE GPWS WARNING SOUNDED.
Narrative: WE WERE CLRED FOR THE ILS AND THE ACFT CONFIGN WAS FLAPS 15 DEGS, GEAR UP. THE AIRSPD WAS 170 KTS AND OUR LOCATION WAS OUTSIDE THE LOM, ON GS AND ON COURSE. I WAS THE PF. AS WE NEARED THE LOM WE HAD A VISUAL ON THE RWY. I DISCONNECTED THE AUTOPLT AND AUTOTHROTTLES AND WAS FLYING MANUALLY. WE WERE ABOUT 3 MI BEHIND ANOTHER ACFT AND #2 FOR LNDG. THE R THROTTLE WAS 'STIFFER' THAN NORMAL, MAKING SYMMETRICAL THRUST APPLICATIONS TROUBLESOME. AS WE APCHED THE LOM, WE CONTACTED TWR AND WERE GIVEN LNDG CLRNC. MY ATTN ON THE ACFT AHEAD, INST XCHK AND THE THROTTLE DIFFICULTY COMPLETELY ABSORBED MY FOCUS. SO MUCH SO, THAT I MISSED THE 1000 FT AGL CALL BY THE FO OR IF I HEARD IF, MY BRAIN DIDN'T REGISTER THE INFO. IT WASN'T UNTIL THE GPWS VOCAL ANNUNCIATION OF 'TOO LOW, GEAR' SOUNDED THAT I REALIZED THE ACFT WASN'T CONFIGURED FOR LNDG. THE GEAR WAS EXTENDED, AND THEN FLAPS WERE EXTENDED TO LNDG POS IN NORMAL SEQUENCE. THE LNDG WAS MADE WITHOUT FURTHER INCIDENCE. BESIDES THE EMBARRASSMENT OF MAKING A 'STUDENT PLT' ERROR, I FELT THE DREAD OF REALIZATION OF 'WHAT MIGHT HAVE BEEN,' HAD THE GPWS NOT FUNCTIONED! PERHAPS THE EARLY WAKEUP (XA00 AM), THE END OF A 4-DAY TRIP, THE MID-AFTERNOON SLUMP OR JUST PLAIN 'GET-HOME-ITIS' OR ALL OF THESE TOGETHER IN ADDITION TO MY OWN COMPLACENCY, ADDED UP TO A VERY DUMB MISTAKE WITH POSSIBLY VERY SERIOUS CONSEQUENCES.
