Aircraft
On departure; we had a normal takeoff in gusty conditions. As gear was retracted we detected a sound and feel like a stick shaker. The Captain; who was flying; said it occurred several times. Normal airspeed and configuration were noted. Upon climb out; a Warn Elex status message appeared; then extinguished a few times; remaining out for the duration of the flight. At initial level off at FL350; the LE SLAT ASSYM EICAS came on; with the flap indicator showing needles between the 0-1 position. No adverse control; but the indication persisted. The Relief Pilot was called to observe the wings and Dispatch and Maintenance Control were obtained by radio. It was agreed that the safest course of action; in light of the stick shaker and the LE SLAT ASSYM was to return to the departure airport. It was noted by the pilots that the LE SLAT ASSYM had occurred previously; as indicated in the LOG History. While EICAS was on; we referred to the QRH procedures; requesting descent and coordinating return. EICAS extinguished en route. We executed holding to slow and carefully monitored initial flap configuration. All indications were normal. The Captain flew the ILS and landed normally. The crew coordination was great; and the Relief Pilot provided the landing performance data for possible contingencies; since Dispatch advised us that computerized performance was down.
A B767 Captain felt the stick shaker as the landing gear were retracted on takeoff followed by an intermittent Warn Elex Status Message. At cruise the LE SLAT ASSYM EICAS alerted so the flight returned to the departure airport.
