Narrative:

While configuring aircraft for landing, EICAS message 'trailing edge flap disagreement' and 'trailing edge flaps' light illuminated, with flaps 15 degrees at +/-2000 ft MSL. Since normal deployment of flaps was disabled, a go around was executed. I was PF (captain). The first officer and I complied with cockpit operating manual procedures, restoring normal power (hydraulic) to flaps. A normal 30 degree flaps landing was made. A maintenance write-up was initiated against the flaps to ensure the cause of the lights was not simply the flap handle possibly remaining out of the detent longer than 25 seconds.

Title: A B757 CREW MADE A GAR WHEN THE TRAILING EDGE FLAPS LOCKED OUT.

Narrative: WHILE CONFIGURING ACFT FOR LNDG, EICAS MESSAGE 'TRAILING EDGE FLAP DISAGREEMENT' AND 'TRAILING EDGE FLAPS' LIGHT ILLUMINATED, WITH FLAPS 15 DEGS AT +/-2000 FT MSL. SINCE NORMAL DEPLOYMENT OF FLAPS WAS DISABLED, A GAR WAS EXECUTED. I WAS PF (CAPT). THE FO AND I COMPLIED WITH COCKPIT OPERATING MANUAL PROCS, RESTORING NORMAL PWR (HYD) TO FLAPS. A NORMAL 30 DEG FLAPS LNDG WAS MADE. A MAINT WRITE-UP WAS INITIATED AGAINST THE FLAPS TO ENSURE THE CAUSE OF THE LIGHTS WAS NOT SIMPLY THE FLAP HANDLE POSSIBLY REMAINING OUT OF THE DETENT LONGER THAN 25 SECONDS.
