On landing configuration when going from flaps 20 to flaps 25 received [a] Trailing Edge flaps disagree EICAS and amber Trailing edge discreet light ON. Performed a Go Around and kept speed below 165kias. performed Trailing Edge Flap disagree QRH and and received vectors back to [the runway]. Ensure priority handling [from ATC] then ran all appropriate checklists [for] landing. Crew switched from First Officer (FO) Pilot Flying (PF) to Captain Pilot Flying (PF) on downwind. On final approach when gear was extended EICAS reset with no faults. Taxied to gate with flaps extended for mechanical precaution. I am not sure of the mechanical nature that caused this event. I am assuming some sensor problem or computer error.
On Approach; we had been slowed to 170 Knots and Cleared for the ILS. We had been assigned 170 Knots until ZZZZZ Intersection. Configuration was Gear Up; Flaps 20; descending on the Glide Slope. About a half mile prior to ZZZZZ Intersection I called for Gear Down; and started to slow to Flaps 20 Bug of 160 Knots; once the gear was down I called for Flaps 25. Shortly after that we got a Trailing Edge Flap Disagree EICAS message with an associated Trailing Edge Discrete Light. We executed a Go Around; leaving the flaps in the extended position and remained slowed to 165 knots. The Flaps Handle was selected to Flaps 25; however the indicator showed the flaps just past the 20 Degrees. Staying at 165 Knots assured we would not over speed the flaps. Ran the QRH; and while on approach to [the runway] for the second approach; once the gear lowered again; the flaps moved to the original commanded position of Flaps 25. All Flap Message/Discrete lights extinguished. We landed; wrote up the event and debriefed with Maintenance.Received Trailing Edge Flap Disagree.This was a maintenance issue with the airplane. Felt like we were safe and complied with FOM and QRH and proceeded in the safest; most conservative way.
B767 flight crew reported a trailing edge flap disagree message that resulted in a go-around.
