From RBF:
FDR shows touchdown at Vref 143 kt. in quartering tailwind 4000' approx down runway. 5000' remaining sufficient for dry, but not wet.
Exited rwy at 79 kt.
"Question asked about poor deceleration [64 kt. over 5000' ] -- TSB will investigate."
Good question, wonder how you would make out rejecting close to V1 at max weight for the conditions if that is all the deceleration available?
Sounds like the investigators still have a lot of work to do.
