B727 captain experienced aircraft stickshaker when pwring back after takeoff for noise abatement procedure due to incorrect wing flap setting made by the first officer. He immediately increased power and the first officer added required flap setting to regain full aircraft control.

Narrative:
After taking off on runway 18L at cvg, followed noise abatement procedure. I was the so. Captain was flying and called for special quiet EPR of 1.65 EPR and flaps to 5 degrees. I reduced power to 1.65 EPR and first officer selected flaps to 2 degrees instead of 5 degrees. Captain maintained V2 +10. When we were at 2 degrees, stick shaker initiated. Captain initiated recovery and we all noticed at the same time that flaps were not in proper position. First officer reselected flaps to 5 degrees. At this time we were now at takeoff power. We may have set off the noise monitors at cvg due to this high power setting. I think this could have been avoided if first officer had monitored the flap handle position and the flap retraction sequence. Also, I could have doublechked the flap handle to be in the correct position and monitor more carefully the flap retraction.

Title: B727 CAPT EXPERIENCED ACFT STICKSHAKER WHEN PWRING BACK AFTER TKOF FOR NOISE ABATEMENT PROC DUE TO INCORRECT WING FLAP SETTING MADE BY THE FO. HE IMMEDIATELY INCREASED PWR AND THE FO ADDED REQUIRED FLAP SETTING TO REGAIN FULL ACFT CTL.
Narrative: AFTER TAKING OFF ON RWY 18L AT CVG, FOLLOWED NOISE ABATEMENT PROC. I WAS THE SO. CAPT WAS FLYING AND CALLED FOR SPECIAL QUIET EPR OF 1.65 EPR AND FLAPS TO 5 DEGS. I REDUCED PWR TO 1.65 EPR AND FO SELECTED FLAPS TO 2 DEGS INSTEAD OF 5 DEGS. CAPT MAINTAINED V2 +10. WHEN WE WERE AT 2 DEGS, STICK SHAKER INITIATED. CAPT INITIATED RECOVERY AND WE ALL NOTICED AT THE SAME TIME THAT FLAPS WERE NOT IN PROPER POS. FO RESELECTED FLAPS TO 5 DEGS. AT THIS TIME WE WERE NOW AT TKOF PWR. WE MAY HAVE SET OFF THE NOISE MONITORS AT CVG DUE TO THIS HIGH PWR SETTING. I THINK THIS COULD HAVE BEEN AVOIDED IF FO HAD MONITORED THE FLAP HANDLE POS AND THE FLAP RETRACTION SEQUENCE. ALSO, I COULD HAVE DOUBLECHKED THE FLAP HANDLE TO BE IN THE CORRECT POS AND MONITOR MORE CAREFULLY THE FLAP RETRACTION.
