A B737-300 CAPT RPTED THAT WAKE TURB WAS ENCOUNTERED AT ELP; CAUSING A RADICAL ROLLING MOMENT.

Narrative

TAXIED OUT FOR DEP FROM ELP. I BRIEFED THE FO TO EXPECT ME TO USE AN 'ADVERSE CONDITION PROFILE' FOR TKOF; AS THE WINDS WERE GUSTING TO 35 KTS FROM THE W RIGHT DOWN RWY 26L. WE TAXIED INTO POS AND HELD; WHILE A COMPANY B737-200 ACFT DEPARTED RWY 22 AHEAD OF US. THE RWYS INTERSECT AT THE DEP ENDS. THE -200 WAS AIRBORNE AND AT OR ABOUT OUR 1 O'CLOCK POS. WHEN THE TWR CLRED US FOR TKOF; THE -200 WAS ALREADY WELL OUT OF THE WAY; SO I ADVANCED PWR AND WE STARTED THE DEP ROLL. I HAD BRIEFED THE FO I WOULD USE THE INCREASED VR (152 KTS) BECAUSE OF THE GUSTY WINDS; SO HE WAS IN THE PICTURE AS TO MY INTENTIONS. WE REACHED V1; WHICH HE CALLED; AND VR; WHICH HE ALSO CALLED OUT; AND I CONTINUED DOWN THE RWY UNTIL REACHING 152 KIAS; AT WHICH POINT I ROTATED TO A 15 DEG NOSE UP ATTITUDE AND BEGAN CLBING OUT. AT THE POINT AT WHICH I CAME BACK INTO THE COCKPIT TO A FULL 'HEADS DOWN' POS TO MONITOR THE CLB; WE ENCOUNTERED A RADICAL ROLLING MOMENT TO THE R. I USED FULL AILERON (I THINK TO THE STOPS) AND A LITTLE L RUDDER TO COUNTER IT AND WAS STILL UNABLE TO KEEP THE WINGS COMPLETELY LEVEL. WE ALSO LOST 30 KTS OF INDICATED AIRSPD DURING THE ROLL. WE DEVIATED ABOUT 5 DEGS OFF HDG TO THE R BECAUSE OF THE ROLLING MOVEMENT; WHICH I CORRECTED AND WE CONTINUED THE CLBOUT; CLEANING UP NORMALLY. IN RETROSPECT; THE SIT WAS PROBABLY MY FAULT; IN THAT I DID NOT CONSIDER THE IMPLICATIONS OF THE -200 WAKE TURB WE MIGHT ENCOUNTER RIGHT AT THE JUNCTURE OF THE RWYS. HAVING SAID THAT; HOWEVER; I ALSO FEEL THE TWR DESERVES A LITTLE CRITICISM FOR NOT CONSIDERING IT; EITHER. TO BE FAIR; THOUGH; THEY WERE PROBABLY DOING EVERYTHING CORRECTLY FROM THEIR STANDPOINT; SINCE THE -200 WAS NOT A HVY JET AND DID NOT NECESSITATE A LONGER WAIT FOR OUR TKOF CLRNC BEHIND THEM. I FEEL WE ENCOUNTERED WINDSHEAR; ALONG WITH THE WAKE TURB FROM THE -200; AT ABOUT 150 FT AGL. HAD I NOT DECIDED TO USE THE INCREASED VR FOR THE TKOF; THE SIT MIGHT WELL HAVE HAD VERY SERIOUS CONSEQUENCES. THE EXTRA 20 KTS I WAS CARRYING AT THE POINT WE ENCOUNTERED THE TURB WAS A REAL CUSHION. SO FAR AS SAFETY IS CONCERNED; IN MY OPINION; I FEEL WE SHOULD PROBABLY DO MORE TO TRAIN FOR THESE TYPES OF SITS; THOUGH I AM NOT SURE WE COULD DUPLICATE THE SIT IN A SIMULATOR WITHOUT READOUTS FROM THE ACFT. I OFFER THIS RPT SO THAT IT MIGHT NOT HAPPEN TO SOMEONE ELSE. CONSIDER THE IMPLICATIONS OF INTERSECTING FLT PATHS; EVEN WHEN THE ACTUAL ACFT ITSELF IS NOT A FACTOR.
