YouTuber and AA F/O Juan Browne does an excellent briefing on this with hydraulic system charts and such. He has a lot of time on the 757. He also points out the same jet had a no-flap landing back in February.

It is surprising they didn’t go to Liberia. They would have been there before they were done with the checklist.

I was in San Jose 3 weeks ago getting ready to leave when the handler said we couldn’t go because there was an inbound emergency. Turned out to be a DHL 757 returning after some sort of abnormal. Thankfully, it landed without incident. I’d be curious to compare the tail numbers.

Supposedly landed 07 with a 10kt tail wind.
From another source:


“The FCOM gives a landing distance of approx 5,400 ft for Hydraulic System Left Inop, good braking, MLW, 3,000 ft elev, 10 kt tail, and 1% uphill slope. The runway length is 9,878 ft. “
Can’t verify the accuracy of the data.

The problem appeared to asymmetric braking and/or reverse thrust, not over-run. They still had runway left, although it's possible somebody panicked with the end approaching.

Looks like they still had 2,500 ft useable runway left. Tried to turn off on high speed K without nose wheel steering..

No reason why just using rudder pedals wouldn’t work but they were going way too fast if that is what they tried.

My understanding is the rudder pedals would deflect the rudder (using center and right system) but not nose wheel w/o left system….ineffective under 60 knots. Our book say to use differential thrust and braking to clear runway if able..nothing about rudder steering…of course that all would be after stopping and assuring controllability.
