Narrative:

During descent for final approach and slowing to 180 KTS, first officer asked for flaps 5 degrees at about 220 KTS. I (captain) selected flaps 5 degrees and noticed no flap movement on flap indicator or amber leading edge in-transit light. Told first officer to maintain 210 KTS and informed ATC we would need to discontinue approach to work on a flight control problem. Checked hydraulic pressure and quantity to find all normal. Referenced QRH trailing edge flap disagree. Spoke with dispatch and maintenance. Maintenance asked me to cycle leading edge dc circuit breaker, after ensuring that flap handle was up. Proceeded with all flaps and landing. Determined 4900 ft of runway length required from odm. Asked first officer to check on field conditions and we would need runway 27R. Determined vref of 177 KTS. I spoke with flight attendant and passenger. I took control of the aircraft and first officer completed descent, approach and landing checklist. Declared an emergency and completed approach and landing. Flap malfunction checklist has always been very confusing. I continued for 2 days to review my actions, including reviewing QRH. After 2 days I realized that I went from trailing edge disagree to all flaps up landing incorrectly. I should have completed trailing edge flaps up landing checklist. This checklist would have led me to use the alternate flaps master switch to extend leading edge devices and lower vref by 15 KTS.

Title: AFTER A QUICK REF TO THE TRAILING EDGE QRH AND A CONFERENCE WITH COMPANY GND PERSONNEL, A NO FLAP APCH AND LNDG IS FLOWN BY A B737 FLT CREW WHEN UNABLE TO EXTEND THEIR FLAPS BY USE OF NORMAL MEANS AT ATL.

Narrative: DURING DSCNT FOR FINAL APCH AND SLOWING TO 180 KTS, FO ASKED FOR FLAPS 5 DEGS AT ABOUT 220 KTS. I (CAPT) SELECTED FLAPS 5 DEGS AND NOTICED NO FLAP MOVEMENT ON FLAP INDICATOR OR AMBER LEADING EDGE IN-TRANSIT LIGHT. TOLD FO TO MAINTAIN 210 KTS AND INFORMED ATC WE WOULD NEED TO DISCONTINUE APCH TO WORK ON A FLT CTL PROB. CHKED HYD PRESSURE AND QUANTITY TO FIND ALL NORMAL. REFED QRH TRAILING EDGE FLAP DISAGREE. SPOKE WITH DISPATCH AND MAINT. MAINT ASKED ME TO CYCLE LEADING EDGE DC CIRCUIT BREAKER, AFTER ENSURING THAT FLAP HANDLE WAS UP. PROCEEDED WITH ALL FLAPS AND LNDG. DETERMINED 4900 FT OF RWY LENGTH REQUIRED FROM ODM. ASKED FO TO CHK ON FIELD CONDITIONS AND WE WOULD NEED RWY 27R. DETERMINED VREF OF 177 KTS. I SPOKE WITH FLT ATTENDANT AND PAX. I TOOK CTL OF THE ACFT AND FO COMPLETED DSCNT, APCH AND LNDG CHKLIST. DECLARED AN EMER AND COMPLETED APCH AND LNDG. FLAP MALFUNCTION CHKLIST HAS ALWAYS BEEN VERY CONFUSING. I CONTINUED FOR 2 DAYS TO REVIEW MY ACTIONS, INCLUDING REVIEWING QRH. AFTER 2 DAYS I REALIZED THAT I WENT FROM TRAILING EDGE DISAGREE TO ALL FLAPS UP LNDG INCORRECTLY. I SHOULD HAVE COMPLETED TRAILING EDGE FLAPS UP LNDG CHKLIST. THIS CHKLIST WOULD HAVE LED ME TO USE THE ALTERNATE FLAPS MASTER SWITCH TO EXTEND LEADING EDGE DEVICES AND LOWER VREF BY 15 KTS.
