Flight Crew Landed in Emergency Condition
Aircraft
On approach; noticed aircraft was hard to slow down when flaps selected to 1 and then 5; slowing to 180 KTS. Noticed the stall indication (red zipper) slowly come up 10-15 KTS below our airspeed around currently 190 KTS. [I] noticed that the flap indication showed flaps at zero. I believe the flaps were at zero; however; we never received an EICAS indication of a flap failure. We advised Approach and were vectored north to deal with problem. Due to low fuel (7.3) and without an actual EICAS indication; the Captain decided to do a flap zero landing and ran an All Flaps and Slats Up Landing even though the checklist advised to only run with a LE or TE Slat/Flap Asymmetry EICAS indication. Vectored to longest runway available; transferred controls and the Captain landed without incident. Also checked brake cooling chart after the 'After Landing Checklist'. Maintenance should look into why no EICAS indication was given when flaps did not extend. Maintenance close out found that '#1 FSEU with no power'. Could have [turned] into a stall at low altitude very easily had we not noticed the zero indication.
B757-200 First Officer reported loss of leading and trailing edge flaps on approach with no EICAS alert. Flight made a safe zero-flap landing.
