Narrative:
Stick shaker during approach. ILS runway 2R approach to bna IMC. Approach control requested early slow and 150 degree turn through final course for separation. First officer noticed deceleration through target and I went from idle to 80% N1 to correct. Got stick shaker as deceleration continued, maximum N1 on throttle. Leveled wings, disconnected autoplt and recovered in less than 5 seconds. Continued approach to uneventful landing. Debriefed events with check airman deadheading in cabin. He said event felt like initial go around, smooth throughout. Passenger reaction was minimal. Buffet or stall never encountered. Distraction of multiple events drew appropriate attention away from airspeed. Personal shock of event has impressed upon me that immediate action procedures and simulator training is effective and for me to double my attentiveness during this phase of flight. Supplemental information from acn 563452: IMC instrument approach to runway 2R ILS at bna. ATC flew us through the localizer and had us slow early to approach speed to gain spacing on the preceding aircraft. During the vector back to the localizer, the aircraft leveled off at the assigned intercept altitude. The combination of the turn and leveloff caused the aircraft to decelerate through our target speed, so I made an 'airspeed' call. The captain immediately added power and at the onset of the stick shaker he rolled wings level and continued to advance power to maximum, while disconnecting the autoplt. The aircraft smoothly flew out of the stick shaker in a few seconds. We corrected onto the ILS and landed uneventfully. Buffet or loss of altitude was never encountered during the recovery.

Title: B737-300 CREW RPTED THE STICK SHAKER ACTIVATED WHILE ON VECTORS FOR THE APCH AT BNA.
Narrative: STICK SHAKER DURING APCH. ILS RWY 2R APCH TO BNA IMC. APCH CTL REQUESTED EARLY SLOW AND 150 DEG TURN THROUGH FINAL COURSE FOR SEPARATION. FO NOTICED DECELERATION THROUGH TARGET AND I WENT FROM IDLE TO 80% N1 TO CORRECT. GOT STICK SHAKER AS DECELERATION CONTINUED, MAX N1 ON THROTTLE. LEVELED WINGS, DISCONNECTED AUTOPLT AND RECOVERED IN LESS THAN 5 SECONDS. CONTINUED APCH TO UNEVENTFUL LNDG. DEBRIEFED EVENTS WITH CHK AIRMAN DEADHEADING IN CABIN. HE SAID EVENT FELT LIKE INITIAL GAR, SMOOTH THROUGHOUT. PAX REACTION WAS MINIMAL. BUFFET OR STALL NEVER ENCOUNTERED. DISTR OF MULTIPLE EVENTS DREW APPROPRIATE ATTN AWAY FROM AIRSPD. PERSONAL SHOCK OF EVENT HAS IMPRESSED UPON ME THAT IMMEDIATE ACTION PROCS AND SIMULATOR TRAINING IS EFFECTIVE AND FOR ME TO DOUBLE MY ATTENTIVENESS DURING THIS PHASE OF FLT. SUPPLEMENTAL INFO FROM ACN 563452: IMC INST APCH TO RWY 2R ILS AT BNA. ATC FLEW US THROUGH THE LOC AND HAD US SLOW EARLY TO APCH SPD TO GAIN SPACING ON THE PRECEDING ACFT. DURING THE VECTOR BACK TO THE LOC, THE ACFT LEVELED OFF AT THE ASSIGNED INTERCEPT ALT. THE COMBINATION OF THE TURN AND LEVELOFF CAUSED THE ACFT TO DECELERATE THROUGH OUR TARGET SPD, SO I MADE AN 'AIRSPD' CALL. THE CAPT IMMEDIATELY ADDED PWR AND AT THE ONSET OF THE STICK SHAKER HE ROLLED WINGS LEVEL AND CONTINUED TO ADVANCE PWR TO MAX, WHILE DISCONNECTING THE AUTOPLT. THE ACFT SMOOTHLY FLEW OUT OF THE STICK SHAKER IN A FEW SECONDS. WE CORRECTED ONTO THE ILS AND LANDED UNEVENTFULLY. BUFFET OR LOSS OF ALT WAS NEVER ENCOUNTERED DURING THE RECOVERY.
