Narrative:
B767-300 aircraft planned takeoff weight of 400.5 pounds. Outside air temperature 14 degrees C, flaps 5 degrees, packs off. Load closeout was tow of 396.8 pounds. This allowed 5 degree flaps, packs on takeoff. Headwind of 5 KTS runway 9L. I elected to make a packs off takeoff anyway. On takeoff, nose felt heavy. I did not trim but used a gradual rotation to liftoff. Speed was reference +20 KTS at gear retraction 8 degrees nose up. At gear retraction, approximately 200 ft, we encountered a stick shaker of 3-4 seconds duration. I lowered the nose 1-2 degrees, stick shaker stopped and we continued climb with no further incident. Arrival fuel was 2000+ pounds which I would not expect if the aircraft was heavier than planned. I used +10 KTS for landing with no problems in the touchdown. Dispatch was notified and they requested a passenger count which was equal to the closeout. A bag count might have been performed.

Title: B767-300 ACFT HEAVILY LOADED WITH POSSIBLE OVERWT BAGGAGE EXPERIENCED STICK SHAKER AT GEAR RETRACTION, 200 FT. RPTR CAPT LOWERED NOSE TO COUNTER THE IMPENDING STALL AND FLEW OUT OF THE SHAKER.
Narrative: B767-300 ACFT PLANNED TKOF WT OF 400.5 LBS. OUTSIDE AIR TEMP 14 DEGS C, FLAPS 5 DEGS, PACKS OFF. LOAD CLOSEOUT WAS TOW OF 396.8 LBS. THIS ALLOWED 5 DEG FLAPS, PACKS ON TKOF. HEADWIND OF 5 KTS RWY 9L. I ELECTED TO MAKE A PACKS OFF TKOF ANYWAY. ON TKOF, NOSE FELT HVY. I DID NOT TRIM BUT USED A GRADUAL ROTATION TO LIFTOFF. SPD WAS REF +20 KTS AT GEAR RETRACTION 8 DEGS NOSE UP. AT GEAR RETRACTION, APPROX 200 FT, WE ENCOUNTERED A STICK SHAKER OF 3-4 SECONDS DURATION. I LOWERED THE NOSE 1-2 DEGS, STICK SHAKER STOPPED AND WE CONTINUED CLB WITH NO FURTHER INCIDENT. ARR FUEL WAS 2000+ LBS WHICH I WOULD NOT EXPECT IF THE ACFT WAS HEAVIER THAN PLANNED. I USED +10 KTS FOR LNDG WITH NO PROBS IN THE TOUCHDOWN. DISPATCH WAS NOTIFIED AND THEY REQUESTED A PAX COUNT WHICH WAS EQUAL TO THE CLOSEOUT. A BAG COUNT MIGHT HAVE BEEN PERFORMED.
