On approach and selecting flaps from 1 to 5; EICAS message 'LE Flap Disagree' appeared. The Captain broke off the approach; declared an emergency; and we ran the QRH procedure. Upon completion of the checklist we maneuvered under radar vectors for a flaps 20 landing. Landed and cleared the runway and had the ARFF clear the gear/flaps area before continuing to the gate. Became aware today that this may be a NTSB reportable event and therefore the CVR circuit breaker should have pulled.
Upon later discussion it was determined that we should have pulled the circuit breaker for the data recorder and notified maintenance since the landing was a flight control anomaly. The event involved the Captain; First Officer and Relief Pilot (myself). The failure to pull the circuit breaker was the deviation causing this report to be submitted.
B767 flight crew experienced a LE Flap Disagree EICAS message when the flap lever was moved from 1 to 5 during approach. A go around initiated and the QRH consulted prior to returning for a flaps 20 landing.
