Narrative:
On visual approach to runway 14R, ord, approximately 3 mi intrail of large transport (TCAS verified separation). Slight turbulence on final captain elected to fly slightly high on GS. Approximately 50 ft AGL, aircraft rolled rapidly to right then to left. Recovery started immediately, with 'firewall power'. Aircraft flew out of turbulence. Go around created conflict with departing traffic, but traffic in sight visually and TCAS issued no warnings. Vectored around for 14R again no further problems.

Narrative: ON VISUAL APCH TO RWY 14R, ORD, APPROX 3 MI INTRAIL OF LGT (TCAS VERIFIED SEPARATION). SLIGHT TURB ON FINAL CAPT ELECTED TO FLY SLIGHTLY HIGH ON GS. APPROX 50 FT AGL, ACFT ROLLED RAPIDLY TO R THEN TO L. RECOVERY STARTED IMMEDIATELY, WITH 'FIREWALL PWR'. ACFT FLEW OUT OF TURB. GAR CREATED CONFLICT WITH DEPARTING TFC, BUT TFC IN SIGHT VISUALLY AND TCAS ISSUED NO WARNINGS. VECTORED AROUND FOR 14R AGAIN NO FURTHER PROBLEMS.
