Narrative:

Established on final approach flaps 20 degrees. New co-pilot waited until after OM to lower landing gear. Landing gear still in transition to full, the flaps were extended to 25 degrees and a confign warning occurred until landing gear was fully extended. Flaps electrically shut off at approximately 24 degrees. Because the runway was long and dry and speed was approximately 140 KIAS, we continued the approach to land without incident at slightly less than landing flaps.

Original NASA ASRS Text

Title: B767 FLT CREW USES WRONG GEAR EXTENSION PROCS DURING APCH CAUSING AN UNSTABILIZED APCH TO ATL.

Narrative: ESTABLISHED ON FINAL APCH FLAPS 20 DEGS. NEW CO-PLT WAITED UNTIL AFTER OM TO LOWER LNDG GEAR. LNDG GEAR STILL IN TRANSITION TO FULL, THE FLAPS WERE EXTENDED TO 25 DEGS AND A CONFIGN WARNING OCCURRED UNTIL LNDG GEAR WAS FULLY EXTENDED. FLAPS ELECTRICALLY SHUT OFF AT APPROX 24 DEGS. BECAUSE THE RWY WAS LONG AND DRY AND SPD WAS APPROX 140 KIAS, WE CONTINUED THE APCH TO LAND WITHOUT INCIDENT AT SLIGHTLY LESS THAN LNDG FLAPS.
