Narrative:

My first officer was flying, cleared for a visual to runway 29R at tucson. We were high. I was changing frequency to talk to tower and completing the before landing checklist. At approximately 2000 ft AGL, stick shaker occurred which surprised both of us. By that time, 2ND stick shaker occurred. I took controls, added power, looked around cockpit momentarily and noticed flight spoilers were extended. Retracted spoilers and flew a normal landing and approach. No injuries and no damage. After landing, I talked to first officer and suggested when spoilers were deployed, he never takes his hand off the lever until they are fully retracted. In this aircraft, it is very easy to forget about the spoilers being extended as almost every CRJ200 pilot can attest to at one time or another, myself included. Now, whenever I have a new first officer to fly with, my brief will include a requirement to keep a hand on the spoilers at all times when extended. Supplemental information from acn 620160: as we were being vectored to the final approach course, we were high and approach said we could 'south-turn' along final to lose altitude. I slowed enough to get gear down and full flaps. Spoilers were deployed to aid in the higher than normal descent rate. As airspeed bled off and we weren't at a steep enough descent to increase or maintain airspeed, so we got the stick shaker activated and autoplt disconnected. I took the controls and started the nose slowly over and the stick shaker went off again. The captain took the controls and advanced thrust, stowed the flight spoilers and the aircraft immediately was under control. Contributing factor were high workload time -- loss of situational awareness of airspeed.

Title: STICK SHAKER ACTIVATED ON AN APCHING CRJ200 WHEN THE FO FAILS TO MONITOR AIRSPD WITH THE SPOILERS DEPLOYED ON A HIGH APCH TO TUS, AZ.

Narrative: MY FO WAS FLYING, CLRED FOR A VISUAL TO RWY 29R AT TUCSON. WE WERE HIGH. I WAS CHANGING FREQ TO TALK TO TWR AND COMPLETING THE BEFORE LNDG CHKLIST. AT APPROX 2000 FT AGL, STICK SHAKER OCCURRED WHICH SURPRISED BOTH OF US. BY THAT TIME, 2ND STICK SHAKER OCCURRED. I TOOK CTLS, ADDED PWR, LOOKED AROUND COCKPIT MOMENTARILY AND NOTICED FLT SPOILERS WERE EXTENDED. RETRACTED SPOILERS AND FLEW A NORMAL LNDG AND APCH. NO INJURIES AND NO DAMAGE. AFTER LNDG, I TALKED TO FO AND SUGGESTED WHEN SPOILERS WERE DEPLOYED, HE NEVER TAKES HIS HAND OFF THE LEVER UNTIL THEY ARE FULLY RETRACTED. IN THIS ACFT, IT IS VERY EASY TO FORGET ABOUT THE SPOILERS BEING EXTENDED AS ALMOST EVERY CRJ200 PLT CAN ATTEST TO AT ONE TIME OR ANOTHER, MYSELF INCLUDED. NOW, WHENEVER I HAVE A NEW FO TO FLY WITH, MY BRIEF WILL INCLUDE A REQUIREMENT TO KEEP A HAND ON THE SPOILERS AT ALL TIMES WHEN EXTENDED. SUPPLEMENTAL INFO FROM ACN 620160: AS WE WERE BEING VECTORED TO THE FINAL APCH COURSE, WE WERE HIGH AND APCH SAID WE COULD 'S-TURN' ALONG FINAL TO LOSE ALT. I SLOWED ENOUGH TO GET GEAR DOWN AND FULL FLAPS. SPOILERS WERE DEPLOYED TO AID IN THE HIGHER THAN NORMAL DSCNT RATE. AS AIRSPD BLED OFF AND WE WEREN'T AT A STEEP ENOUGH DSCNT TO INCREASE OR MAINTAIN AIRSPD, SO WE GOT THE STICK SHAKER ACTIVATED AND AUTOPLT DISCONNECTED. I TOOK THE CTLS AND STARTED THE NOSE SLOWLY OVER AND THE STICK SHAKER WENT OFF AGAIN. THE CAPT TOOK THE CTLS AND ADVANCED THRUST, STOWED THE FLT SPOILERS AND THE ACFT IMMEDIATELY WAS UNDER CTL. CONTRIBUTING FACTOR WERE HIGH WORKLOAD TIME -- LOSS OF SITUATIONAL AWARENESS OF AIRSPD.
