Narrative:

Requested by ATC to maintain speed of 180 KTS until FAF (1400FT). Maintained speed and then called for flaps 30 when the speed was above max extension speed of 170 KTS. The first officer and I caught my mistake right away and the placed the flap handle back to 25. It was so quick that the flaps barely moved beyond 20. I immediately slowed to below 170 KTS and we extended the flaps to the 30 position. Normal landing. This situation may have happened because of wanting to observe the 180 KTS a little to long; a bit tired from the midnight wake up and then rushing to meet the stabilized approach criteria. I am very careful not to ever exceed an aircraft limit and in this case I'm not sure it did occur...but is was close.

Title: A B777 Captain called for Flaps 30 at 180 KTS before landing causing the FLAP LOAD RELIEF to activate. The flap handle was returned to 25 until the aircraft slowed to 170 KTS. Fatigue and time pressure were factors.
