Narrative:

Final approach runway 9R mia. Reported winds as 060 degrees at 10 KTS. Tower issued proper regarding preceding 757 traffic. Our trailing distance was approximately 4 1/2-5 mi I was flying approximately 1/2 DOT high on GS to avoid wake turbulence. The 757 appeared to land slightly long. My plan was to land in the 1ST 1000 ft of the runway and avoid the vortices. I figured with the crosswind any effect would have dissipated. Wrong! At approximately 120 ft above the threshold I encountered a severe right bank of approximately 20-25 degrees of bank. We also received the bank angle warning from the GPWS twice. A bunch of left aileron left rudder and a fistful of power righted the aircraft. My approach speed had deteriorated from a plus 15 to minus 5 at touchdown. The landing was on centerline but slightly firm. After clearing the runway the passenger were briefed on the situation and no one voiced any comments as they departed the aircraft. I thought 4 mi of separation with a nice crosswind would provide enough protection. I was lucky to learn this lesson without injury or damage.

Title: WITH 30 DEG 10 KT XWIND AND 4-5 MI INTRAIL OF A BOEING 757 THE RPTR IN HIS BOEING 727 THOUGHT HE WOULD BE OUT OF THE VORTICES LNDG AT THE 1000 FT POINT BEHIND THE 757 THAT HAD LANDED LONG. HE ENCOUNTERED SEVERE WAKE AT 120 FT AGL. THE RECOVERY REQUIRED AILERON, RUDDER AND PWR TO RIGHT THE ACFT. EXPERIENCED FIRM LNDG.

Narrative: FINAL APCH RWY 9R MIA. RPTED WINDS AS 060 DEGS AT 10 KTS. TWR ISSUED PROPER REGARDING PRECEDING 757 TFC. OUR TRAILING DISTANCE WAS APPROX 4 1/2-5 MI I WAS FLYING APPROX 1/2 DOT HIGH ON GS TO AVOID WAKE TURB. THE 757 APPEARED TO LAND SLIGHTLY LONG. MY PLAN WAS TO LAND IN THE 1ST 1000 FT OF THE RWY AND AVOID THE VORTICES. I FIGURED WITH THE XWIND ANY EFFECT WOULD HAVE DISSIPATED. WRONG! AT APPROX 120 FT ABOVE THE THRESHOLD I ENCOUNTERED A SEVERE R BANK OF APPROX 20-25 DEGS OF BANK. WE ALSO RECEIVED THE BANK ANGLE WARNING FROM THE GPWS TWICE.

AFTER CLRING THE RWY THE PAX WERE BRIEFED ON THE SIT AND NO ONE VOICED ANY COMMENTS AS THEY DEPARTED THE ACFT. I THOUGHT 4 MI OF SEPARATION WITH A NICE XWIND WOULD PROVIDE ENOUGH PROTECTION.
