Narrative:Rolled rapidly to the inverted position and descend almost vertically into the ground while on approach to Billings' runway 27R. Upset caused by wake turbulence from a preceding Boeing 757. Horizontal separation was decreasing below 2.6 miles.
PROBABLE CAUSE: "The pilot-in-command's failure to follow established vortex avoidance procedures, as published in the airman's information manual, to provide his own wake turbulence separation."
